Summary

Oil and gas methane management is the process of reducing methane emissions from oil and gas (O&G) supply chains. These supply chains release methane when pipes and other system parts leak or methane is intentionally vented for operation and safety reasons. We define the Manage Oil & Gas Methane solution as adopting approaches to reduce methane emissions, including fixing leaks in components, upgrading control equipment, changing procedures, and destroying methane by burning methane as a fuel or in flares.

Overview

Methane can be unintentionally released due to imperfections and faults along the supply chain or intentionally released as part of operations and maintenance. Atmospheric methane has a GWP of 81 over a 20-yr time basis and a GWP of 28 over a 100-yr time basis (IPCC, 2023). This means methane is 81 times more effective at trapping heat than CO₂.  Because methane is a short-lived climate pollutant that has a much stronger warming effect than CO₂ over a given time period, abating methane will have a relatively large near-term impact on slowing global climate change (IEA, 2023b).

The first step to reduce methane releases from O&G production is to identify where releases occur along the supply chain. Many occur during O&G extraction as methane is either intentionally vented or unintentionally emitted. The International Energy Agency (IEA, 2024) estimated more than 60% of global energy-related methane emissions originated from the O&G sector in 2023, with the remaining emissions mostly coming from coal use and some bioenergy (Figure 1). The United Nations Environment Programme (UNEP) has formed a transparency and accountability initiative whose members are responsible for 42% of global O&G production. It reported that activities involved in exploration and processing of O&G accounted for 83% of total reported O&G emissions from 2020 to 2023, with production processes being responsible for 90% of those emissions (UNEP 2024). Alvarez et al. (2018) found that in the United States, more than 58% of O&G methane emissions came from production and about 20% came from extraction in 2015.

O&G producers can reduce their methane emissions by preventing its release or by converting it to CO₂ through combustion. Strategies for reducing O&G methane emissions can be put into two broad categories (Climate & Clean Air Coalition [CCAC], 2021):

Device conversion, replacement, and installation is the practice of fixing leaks in pipes, valves, compressors, pumps, and other equipment. This can include converting natural gas–powered devices to electric, driving compressors/pneumatics with air instead of natural gas, or replacing emitting components with non-emitting ones (Pembina Institute, 2024).

Changes to operations and maintenance practices seek to reduce the intentional venting of methane. They include eliminating the need for blow-down (releasing gases during the maintenance or operation of pipe infrastructure), reducing venting, and capturing methane before it is released into the atmosphere, then using it as fuel for product refining or burning it to convert it into CO₂.

Leak detection and repair (LDAR) is the practice of regularly monitoring for methane leaks and modifying or replacing leaking equipment.

Effectiveness

Each Mt of methane that is not emitted avoids 81.2 million t CO₂‑eq on a 20-yr basis and 27.9 million t CO₂‑eq on a 100-yr basis (Smith et al., 2021). The GWP of methane is shown in Table 1. If the methane is burned (converted into CO₂ ), the contribution to climate change will still be less than that of methane released directly into the atmosphere. Methane abatement can have a more immediate impact on future global temperature rise because it has a larger and faster warming effect than CO₂. Mitigating methane emissions in the near term can give us more time for reducing GHG emissions in hard-to-abate sectors.

Cost

The cost of methane abatement will vary depending on the type of O&G production, the methane content of the O&G resource, and the strategies used to address it. We averaged the costs for various abatement strategies; methane content is sufficiently high to utilize methane abatement strategies, and energy infrastructure is available to utilize abated methane. The initial cost to abate 1 Mt of methane is US$594 million, the revenue is about US$193 million, and the overall net savings over a 30-yr amortization period is US$173 million. This means that reducing O&G methane emissions offers a net economic gain for O&G producers. We were not able to find operating cost information for the solution, meaning the net economic gain may be lower in practice. 

We considered the baseline scenario where O&G producers do not have systems or practices in place to monitor or stop methane from escaping to the atmosphere and found very limited cost data. We assumed baseline costs to be 0 for initial costs, operational costs, and revenue because current practices and infrastructure are releasing methane to the atmosphere as a part of their existing cost of doing business. 

Many of the initial cost data for methane abatement come from studies estimating how much capital would be required to reach methane emission targets for the O&G industry. These costs are for the global scale of O&G methane abatement and not from the point of view of an individual O&G producer. These studies do not go into detail about the cost of specific abatement strategies or their potential revenues. The context and assumptions are difficult to identify, since the abatement strategies must be tailored to each site. Ocko et al (2021) noted that most (around 80%) of economically feasible methane abatement actions are from the O&G sector. 

Table 2 shows the costs per t CO₂‑eq. The value of the methane sold, instead of released, will often bring in revenue that covers the costs of abatement. Refer to the Appendix for information on the proportion of strategies that O&G producers could implement at low to no cost.

Learning Curve

Many of the technology solutions for reducing methane emissions are mature, and we were unable to find literature suggesting the costs to implement these solutions will fall in the future. There may be efficiencies to be gained in LDAR, but little research offers insights into the costs of LDAR programs (Delphi Group, 2017, ICF, 2016).

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as gradual, emergency brake, or delayed.

Manage OIl & Gas Methane is an EMERGENCY BRAKE climate solution. It has the potential to deliver a more rapid impact than gradual and delayed solutions. Because emergency brake solutions can deliver their climate benefits quickly, they can help accelerate our efforts to address dangerous levels of climate change. For this reason, they are a high priority.

Caveats

Burning methane produces CO₂. Though the GWP is far less than that of releasing methane into the atmosphere, the practice still creates a negative climate impact. Depending on the type of O&G production, methane abatement is already practiced with natural gas production and is likely to bring added profit. However, oil producers who are not already producing methane for profit may not be able to abate methane at a profit. 

Avoiding fossil fuel extraction, transport, and use is the only way to permanently reduce emissions from O&G production. For many low- and middle-income countries (LMICs), O&G is the main source of energy, and it is challenging for them to completely eliminate O&G from their energy mix while they are simultaneously working to improve living standards. High-income countries can help LMICs develop clean energy infrastructure by providing financial and technological support. This will prevent new investments in O&G infrastructure (Laan, et al., 2024), which would result in ongoing emissions for decades. It would also allow LMICs a realistic pathway to transition away from their existing O&G usage. O&G demand must fall by 80% between 2022 and 2050 to stay in alignment with the net-zero emissions scenarios modeled by IEA (2023c). O&G methane abatement will decrease over time as the O&G industry produces less methane to be abated.

Our assessment does not include the impact of the CO₂ created from the destruction of methane.

Current Adoption

We found little literature quantifying the current adoption of methane management; much of the methane abatement research revolves around the amount of methane that needs to be abated to reach certain climate targets. Based on data from Global Methane Initiative (GMI, 2024), 0 Mt of methane was abated in 2023 and is shown in Table 3.


GMI (2024) provided a conservative estimate of cumulative methane emissions abated each year, with a total of 153.6 Mt CO₂‑eq (5.51 Mt methane) abated as of 2023. The methane is given as a cumulative value to show the incremental increase in total methane abated and to avoid double counting methane abated. GMI members only cover 70% of human-caused methane emissions, and the organization does not capture methane mitigation that occurs outside of GMI members. This suggests that even in years where methane was abated, it would likely still be an underestimate of what may have actually occurred globally. The untapped potential for methane abatement suggests that O&G companies are investing in increasing natural gas production, which may be due to relatively smaller profits from abatement and nonbinding regulations (Shindell et al., 2024).

Adoption Trend

Although there is little research specifically quantifying the adoption of methane abatement strategies over time, we estimate the average adoption trend in recent years to be about 0.35 Mt/yr of methane abated. To create this estimate, we relied on GMI analysis (GMI, 2024). GMI showed methane abatement gradually increasing from 2011 to 2023, then tapering off around 2020 and beginning to decrease among its member organizations. Table 4 shows the adoption trend for O&G methane abatement.

The IEA (2025) compiled country-level reporting for GHG emissions with data up to 2024. However, we were not able to use the data for the adoption trend because the changes in methane emissions could have been due to reasons other than methane abatement. In reality, methane emissions may be affected by multiple factors such as natural disasters, political conditions, changes in O&G demand, and changes in O&G industry practices.

Oil and Gas Climate Initiative (2023) data on methane abatement to date for 12 major O&G companies indicate that methane emissions decreased 50% from 2017 to 2022; however, we cannot assume the rest of the O&G industry has made the same level of progress.

Adoption Ceiling

We found an adoption ceiling of 80.7 Mt/yr of methane based on the IEA’s (2025) estimate for total methane emissions from the O&G sector. We assumed that current O&G methane emissions would remain the same into the future with no changes in O&G production or demand. Table 5 shows the adoption ceiling for O&G methane abatement.

Even in the IEA’s (2023c) highest methane abatement energy scenario, only 93% of the methane emissions are reduced by 2050. This would still leave methane emissions being released into the atmosphere by the O&G sector. Reduced O&G production will reduce the amount of methane emissions produced by the O&G sector and consequently reduce the amount of methane that needs to be controlled with methane abatement.

Achievable Adoption

Based on the limited data available for current adoption and adoption trend, we expect 3.26–8.84 Mt/yr of methane abated. The Achievable – Low value aligns with the IEA (2023c) baseline energy scenario (STEPS), in which partial methane abatement is used but not all technically possible methane is abated. The Achievable – High value aligns with the IEA (2023c) baseline scenario (STEPS), in which full methane abatement is employed (all technically possible methane is abated). We determined this range by taking the total methane abated in these scenarios and dividing by the difference between the target year and 2024 to determine an average amount of methane abated each year to reach the scenario target. Under both scenarios, reduced demand for O&G would reduce methane emissions produced and lower the adoption ceiling possible for methane abatement. Even in scenarios where there is reduced O&G demand, methane abatement would still be required to control fugitive methane emissions from O&G infrastructure and limit global climate change. 

The amount of methane that can be abated varies greatly depending on how much methane the O&G industry produces. If O&G production remains steady, cumulative methane abatement could be 21–81 Mt, according to the IEA energy scenarios. If O&G demand drops 80% (IEA’s Net Zero Emissions scenario), total methane emissions would decline to 18 Mt, and the use of methane abatement would reduce methane emissions further by 17 Mt, leaving only 1 Mt of methane emitted in 2050. 

There has been growing interest from governments and academia to more accurately identify methane emissions using technologies such as satellite sensing (MethaneSat, 2024); UNEP (2024) has set up a monitoring and operator’s alliance group that will share best practices among O&G producers. This alliance group has identified more than 1,200 methane releases, but only 15 responses from government or companies provided detail about the source of the emissions or whether any mitigation action was considered or taken. This shows there are still many opportunities to abate methane emissions. 

More than 150 countries (representing 50% of the world’s human-caused methane emissions) have joined the Global Methane Pledge to reduce methane emissions 30% from 2020 to 2030 (UNEP, 2021). The IEA (2023b) found that many governments already have announced or put into place measures to cut methane emissions, so we expect global methane abatement to grow. 

Conrad et al. (2023) found that the emission inventories reported by the Alberta, Canada, government underestimate the methane emissions from the O&G sector, with a large portion coming from venting. These sources of methane are relatively easier to address and can allow the O&G sector to quickly reduce methane emissions. Table 6 shows the statistical low and high achievable ranges for O&G methane abatement based on different sources for future uptake of O&G methane abatement.

We estimate that the O&G industry is currently abating approximately 0 Gt CO₂‑eq/yr on a 100-yr basis and 0 Gt CO₂‑eq/yr on a 20-yr basis using methane abatement strategies. 

As the O&G industry grows or shrinks its emissions, the amount of methane available to abate will change accordingly. If O&G demand and production stay constant to 2050, we estimate 0.09–0.25 Gt CO₂‑eq/yr of methane could be abated. 

However, if O&G demand drops, the methane abatement potential would drop because the O&G sector is producing less methane. This is projected in the different energy scenarios modeled by the IEA (2023). The range between the current O&G methane abatement and the adoption ceiling is shown in Table 7.

Additional Benefits

Air Quality and Health

Methane reacts with other pollutants to create ground-level ozone (Mar et al., 2022), and incomplete combustion of methane (Figure 2) releases other pollutants such as CO₂, carbon monoxide, black carbon, and volatile organic compounds (Fawole et al., 2016; Johnson and Coderre, 2012; Motte et al., 2021). These pollutants cause respiratory, reproductive, and neurological diseases; cancer; and premature death (Michanowicz et al., 2021; Motte et al., 2021; Tran et al., 2024), so reducing methane release can improve human health. Reducing or stopping flaring at a small number of the largest active sites can significantly reduce air pollution (Anejionu et al., 2015; Johnson and Coderre, 2012). Van Dingenen et al. (2018) estimate that ambitious methane reduction could prevent 70,000 to 130,000 ozone-related deaths worldwide each year.

Food security

Methane reacts with chemicals like VOCs to form tropospheric, or ground-level ozone (Fiore et al., 2002). Ground-level ozone has been linked to reduced crop growth and yields (Mills et al., 2018; Samperdo et al., 2023; Tai et al., 2021). Mitigating methane emissions from O&G could improve food security by reducing ground-level ozone and its harmful impacts on agricultural productivity (Tai et al., 2014; Ramya et al., 2023).

left_text_column_width
Risks

If natural gas prices drop there would be less economic reason for industries to voluntarily abate methane (IEA, 2021). Without policy support enforcing the use of methane abatement technologies, methane could continue to be released into the atmosphere. The use of methane abatement will be needed regardless of whether O&G demand remains the same or decreases over time because it has an immediate effect on reducing global temperature rise in the near term.

Interactions with Other Solutions

Reinforcing

Managing O&G methane can reinforce other solutions that reduce the amount of methane released to the atmosphere. The use of solutions such as applying changes to operations and maintenance; converting, replacing, and installing devices; and LDAR in the O&G industry can help demonstrate the effectiveness and economic case for methane abatement elsewhere and build momentum for adoption of methane abatement in other sectors. 

left_text_column_width

Competing

Managing O&G methane has the potential to compete with solutions that provide clean electricity and solutions that focus on fuel switching in transportation because this solution increases O&G supply and can reduce the cost of O&G products. As a result, it could prolong the use of fossil fuels and slow down the transition to clean electricity.

Trade-offs

Methane abatement could increase the use of O&G resources without a broader strategy to reduce reliance on O&G as an energy resource. The use of methane abatement strategies to extend the use of existing O&G infrastructure, or building new O&G infrastructure, will not result in a net decrease in emissions. Beck et al. (2020) found that more than 57% of the GHG emissions from the O&G supply chain are from methane emissions, while the rest is due to CO₂ emissions (15% from the extraction process and 28% from O&G energy use). Even with methane mitigation, continued use of O&G will generate CO₂ emissions and will contribute to global temperature rise.

Maps Introduction

Methane abatement is recommended for all oil and gas (O&G) production. The levels of achievable abatement can vary geographically, depending on the extraction technology used (i.e., conventional drilling versus hydraulic fracturing). The Middle East, Europe, Asia, and North America are among the largest O&G producers and have the highest related methane emissions, according to the IEA (2025). Research from Shindell et al. (2024) found that North America, Russia, and several countries in the Middle East and Africa have the most methane abatement potential in O&G. O&G methane abatement could be accelerated if technologies and strategies used in high-income countries are shared with other O&G producing countries.

Evidence Base

Consensus of effectiveness of abating methane emissions in the O&G sector: High

There is a high level of consensus about the effectiveness of methane abatement strategies. These strategies can be deployed cost effectively in many cases and have an immediate impact on reducing global temperature rise. 

Authoritative sources such as the IEA (2023d), UNEP (2021), and Global Methane Hub (2024) agree that reducing methane emissions can noticeably reduce the rate of global temperature rise. DeFabrizio et al. (2021) identified that methane abatement strategies such as LDAR, switching from natural gas fuel to electric power, using air for pneumatic devices, and using vapor recovery units could reduce O&G methane emissions by 40% by 2030 based on global 2017 O&G emissions. With methane being the second largest contributor to climate change after CO₂, reductions in methane emissions can quickly reduce global temperature rise.

Others (Marks Levi, 2022; DeFabrizio et al., 2021; Malley et al., 2023) have identified that many methane abatement strategies can use existing technologies, often at low cost. Dunsky (2023) found that implementing 24 of the least expensive abatement measures in the exploration and production phases of Canada’s O&G industry could help Canada achieve its 2030 methane target. The IEA (2023a) noted that the O&G industry was responsible for 80 Mt of methane in 2022 and had the largest potential for abatement in the near term. The O&G industry has the potential to abate 60 Mt of methane by 2030 using abatement strategies; 40% of that could be abated at no net cost based on average natural gas prices from 2017 to 2021 (IEA, 2023a).

The results presented in this document summarize findings from more than 15 reviews and meta-analyses and more than 10 original studies reflecting current evidence from two countries, primarily from the United States and Canada, and from global sources. We recognize this limited geographic scope creates bias, and hope this work inspires research and data-sharing on this topic in underrepresented regions.

MACCs indicate a range of potential climate actions and show at a glance the magnitude of financial return or financial cost across that range. In Figure A1, for the blocks below the horizontal axis, the value received from the sale of the captured methane is greater than the cost of the solution employed. The width of a block shows the annual amount of emissions a technology can abate, with wider blocks abating more emissions than narrower blocks.

MACCs are useful for identifying which climate action could have the most impact at reducing emissions or which options have a net economic gain. However, they do not illustrate the intricacies that may be in play among different climate actions and can lead users to ignore hard-to-abate emissions. The World Bank (2023) identified that MACCs are useful to find which option will reduce emissions by a set percentage but less useful for reducing absolute emissions to near zero.

Summary

Managing coal mine methane (CMM) is the process of reducing methane emissions released from coal deposits and surrounding rock layers due to mining activities. CMM is naturally found in coal seams and released into the atmosphere when the coal seams are disturbed. Coal mines can continue to emit methane even after being closed or abandoned, which is known as abandoned mine methane (AMM). CMM and AMM can be captured and then utilized as a fuel source or destroyed before they reach the atmosphere [U.S. Environmental Protection Agency (EPA), 2024a].

Food security,Health
Air quality
Overview

CMM is released from coal mines before, during, and after active coal mining and from coal being transported (EPA, 2024a). Atmospheric methane has a GWP of 81 on a 20-yr basis and a GWP of 28 on a 100-yr basis (Intergovernmental Panel on Climate Change [IPCC], 2023). This means methane is 81 times more effective at trapping heat than CO₂. Because methane is a short-lived climate pollutant that has a much stronger warming effect than CO₂ over a given time period, abating methane from coal mines will have a powerful near-term impact on slowing global climate change. If capturing methane is not possible, destroying the methane by burning it is preferable to releasing it.

CMM comes from five major sources throughout the coal mine’s life cycle (Figure 1): 

  1. Degasification systems – pipes installed in the ground to move methane into the atmosphere before starting mining
  2. Ventilation air – air escaping from underground mines when fresh air is used to push out underground methane during mining
  3. Surface mines – exposed coal seams that emit methane directly into the atmosphere during mining
  4. Fugitive emissions – already mined coal that emits methane while being transported or stored
  5. Abandoned or closed mines – coal seams and rock strata that are exposed to air, allowing AMM to escape through existing vents or cracks after mine closure.

Source: U.S. Environmental Protection Agency (2024d). Sources of coal mine methane. Retrieved November 5, 2024. https://www.epa.gov/cmop/sources-coal-mine-methane

CMM management relies on several practices and technologies to reduce the amount of methane released into the atmosphere. The CMM that is captured can be used as a fuel at high concentrations and destroyed through flaring or oxidation at low concentrations. The methane captured from degasification systems typically has a high concentration while fugitive and ventilation methane sources are low concentration. CMM management also includes leak detection and repair using satellites, drones, or other technologies to prevent methane from escaping into the atmosphere.

Underground coal mines have more methane abatement strategies available due to higher average methane concentrations and relative ease of capture. Surface coal mines are exposed directly to the atmosphere and can cover large areas, making them more difficult to abate methane, though there are technologies that can reduce CMM emissions. See the Appendix for more details on the abatement technologies specific to underground and surface coal mines.

Effectiveness

Each Mt of methane that is not emitted avoids 81.2 Mt CO₂‑eq on a 20-yr basis and 27.9 Mt CO₂‑eq on a 100-yr basis (Smith et al., 2021). The GWP of methane is shown in Table 1. If the methane is converted into CO₂ through burning the contribution to global climate change will still be less than if the methane were released into the atmosphere. Methane abatement can have a more immediate impact on future global temperature rise because it has a larger and faster warming effect than CO₂. Mitigating methane emissions in the near term can give us more time for reducing GHG emissions in hard-to-abate sectors.

Cost

The cost of methane abatement will vary depending on the type of coal mine, the methane content of the coal seam, the strategies used, and the availability of financial support for methane abatement. For our analysis, we average the costs for various feasible abatement strategies under two general assumptions: sufficiently high methane content for any of the major abatement strategies to be applied (IEA, 2024a) and the ability to use the abated methane on-site or sell it to natural gas companies. The initial cost to abate 1 Mt of methane is US$1.5 billion, the operating cost is about US$130 million, revenue is about US$260 million and the overall net savings over a 30-yr amortization period is US$90 million. We were only able to find revenue information from the IEA (2023b, 2024a), meaning the net cost could be different than shown here due to the site specific nature of methane abatement strategies. 

We considered the baseline scenario to be coal mining practices without methane abatement; all cost estimates here are relative to that scenario.

Cost data were limited for this solution. The available costs for a specific abatement strategy were normalized according to the cost of abating one Mt of methane, and it was assumed that a single strategy abated all of the methane for the coal mine. This results in an overestimate of the effectiveness of any individual strategy. In reality, multiple strategies are likely to be used. The costs shown in Table 2 are for the global scale of coal methane abatement and not from the point of view of an individual coal producer. Many studies that look at global coal methane abatement put multiple abatement strategies together and do not go into detail about the individual technology costs. The IEA (2024a) included costs for individual CMM abatement strategies; however, the costs were only applicable for coal mines that produce enough methane for it to be economically feasible to deploy the specific abatement strategy. Flaring is an effective strategy for destroying captured methane, but will not create revenue in the absence of a carbon market. For more details on important aspects for coal methane abatement strategies, refer to the Appendix.

Learning Curve

Many of the solutions for reducing methane emissions from coal mining are mature. Research from Rystad (2023) found that technologies for abating CMM emissions, such as drainage gas utilization, sealing and rerouting, and flaring, were considered mature in Australian coal mines. Regenerative thermal oxidation technology is in commercial use for destroying volatile organic compounds and can be used for destroying ventilation air methane (VAM), but the manufacturers have little interest in improving the technology for use in coal mines without confirmed markets (GMI, 2018; Rystad, 2023). We do not foresee the costs of implementing these solutions falling in the future. CMM regulations may encourage manufacturers to improve oxidation technology, but the technology is already used commercially, so there may not be large efficiency gains.

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as gradual, emergency brake, or delayed.

Manage Coal Mine Methane is an EMERGENCY BRAKE climate solution. It has the potential to deliver a more rapid impact than gradual and delayed solutions. Because emergency brake solutions can deliver their climate benefits quickly, they can help accelerate our efforts to address dangerous levels of climate change. For this reason, they are a high priority.

Caveats

CMM abatement consists of capturing methane that would otherwise be released into the atmosphere. If the methane is burned, CO₂ will be emitted as a byproduct; however, this provides a net climate benefit compared to the methane that would be emitted. CMM emissions management can be avoided by not extracting, transporting, or using coal in the first place. 

As coal demand drops, the number of closed or abandoned coal mines will increase. These mines will continue to release AMM into the atmosphere for many decades. Sealing underground mines can stop methane from being released, but seals have been known to fail and require ongoing monitoring to verify methane is not escaping (Kholod et al., 2020). Gas collection systems can be used to capture AMM, but the CO₂ produced will need to be captured for complete emission reductions. Flooding underground coal mines is very effective at stopping methane from being released; however, there are concerns about water contamination (McKinsey, 2021).

Our assessment does not include the impact of the CO₂ created from the destruction of methane.

Current Adoption

We estimated that the coal sector abated 0.59 Mt of methane in 2023 and released 40 Mt in 2024 (IEA, 2025). Reports from EPA (2022), and GMI (2023) estimated the amount of CMM abated to date, and the statistical ranges from the sources are shown in Table 3. However, most of the data focused on coal mines in the United States. The EPA (2024b) stated that 0.3 Mt of methane was captured in 2021 due to the Coalbed Methane Outreach Program. CMM is controlled at coal mines for health and safety reasons, but only in 2024 was regulation introduced for reducing methane emissions from the energy sector in the European Union (Assan, 2024).


GMI (2024a) reports that 0.79 Mt of methane was abated from coal mines in 2023 among its member countries. The organization includes 48 GMI member countries but covers only 70% of human-caused methane emissions and does not track methane mitigation that has occurred outside of the group. GMI (2024b) currently lists more than 471 CMM abatement projects in 20 countries worldwide. According to Global Energy Monitor (n.d.), over 6,000 coal mines were active in more than 70 countries as of April 2024. With these data sources, we consider our analysis of the current adoption of CMM abatement as conservative.

Adoption Trend

Although there are little data specifically quantifying the adoption trend of methane abatement strategies, we estimate the median adoption trend to be about 0.60 Mt/yr of methane abated.  Table 4 shows the adoption trend for CMM abatement.

GMI (2024) reported methane abatement staying relatively stable from 2016 to 2023 at about 0.8 Mt/yr, with a small increase to 1.0 Mt of methane in 2019–2022 before decreasing back to 0.8 Mt in 2023, causing the adoption trend to be higher than the current adoption value we state above. The EPA (2024a) Coalbed Methane Outreach Program showed fairly stable emission reductions of around 0.33 Mt/yr between 2016 and 2022. The annual methane emission abatement from this program gradually increased 2003–2011, followed by a continued trend of methane abatement at a slower rate 2011–2022. The IEA (2024b) found that almost 2.0 Mt of methane was emitted in 2023 by the United States coal industry, and 60% of those emissions could be abated.

Adoption Ceiling

We found an adoption ceiling of about 40.3 Mt/yr of methane based on the IEA’s (2025) estimate for total methane emissions from the coal mine sector. We assumed that current CMM emissions would remain the same into the future with no changes in coal production or demand. Table 5 shows the adoption ceiling for coal mine methane abatement.

Even in the IEA’s (2023c) highest methane abatement energy scenario, only 93% of the methane emissions are reduced by 2050. This would still leave the coal sector releasing methane into the atmosphere. Reduced coal production will reduce the amount of methane emissions produced by the coal sector and consequently reduce the amount of methane that needs to be controlled with methane abatement. However, methane abatement will still be important for abating the remaining CMM emissions and the growing proportion of AMM emissions (IEA, 2023c, Kholod et al., 2020).

Achievable Adoption

The amount of methane that could be abated from CMM varies greatly depending on global coal demand. We estimate an achievable adoption range of 2.83–4.40 Mt/yr of methane abated.The Achievable – Low value aligns with the IEA (2023c) Announced Pledges scenario, in which all announced climate policies are met and full methane abatement is employed, but net-zero emissions are not achieved. This range of high and low values was determined by taking the total methane abated in these scenarios and dividing by the difference between the target year and 2024 to determine an average amount of methane abated each year to reach the scenario target. 

The Achievable – High value aligns with Ocko et al.(2021), where all economically and technically feasible methane abatement is employed by 2030. DeFabrizio et al. (2021) estimated that the degasification of underground mines and flaring would be the source of most methane abatement from coal mining, with degasification of surface mines abating a smaller proportion of methane over time. However, research from Kholod et al. (2020) suggested there will be an increase in AMM emissions as coal mines are closed. Methane emissions from AMM are not extensively monitored right now, and there is limited research on the topic. Methane abatement strategies will be needed to abate growing AMM emissions (Zhu et al, 2023). 

In addition, some research suggested CMM is being underestimated, with global emissions being as high as 67 Mt/yr (Assan & Whittle, 2023). If coal demand drops by 90%, as outlined in IEA’s Net Zero Emissions scenario, total coal methane emissions would decline to 3 Mt/yr, and the use of methane abatement would reduce emissions by 2 Mt/yr, leaving only 1 Mt/yr of CMM emitted in 2050. 

With growing interest and investment from governments and academia in identifying methane leaks using technologies such as satellite sensing (MethaneSAT, 2024), the opportunities for methane abatement will increase. Over 150 countries have joined the Global Methane Pledge (representing 50% of the world’s human-caused methane) to reduce methane emissions by 30% of 2020 emissions by 2030 (UNEP, 2021). The IEA (2023a) found that even in a baseline scenario, many governments have announced or put in place measures to cut methane emissions; we would expect a growing trend in global methane abatement to occur. The IEA (2024c) states that in all scenarios global coal demand will decrease. Table 6 shows the statistical low and high achievable ranges for CMM abatement based on different sources for future uptake of CMM abatement.

Left Text Column Width

We estimate that the coal industry is currently abating approximately 0.02 Gt CO₂‑eq/yr on a 100-yr basis and 0.03 Gt CO₂‑eq/yr on a 20-yr basis using methane abatement strategies. This is about 1% of total methane emissions emitted in 2024 (IEA, 2025). 

As the coal industry opens or closes coal mines due to changing coal demand, the opportunities for CMM abatement projects will change along with it. If coal demand gradually drops by 2050, more than 0.12 Gt CO₂‑eq/yr of methane could be abated. However, if coal demand drops more quickly from the implementation of energy and climate policies, the methane abatement potential would drop because the coal sector is producing less methane. This is projected in the different energy scenarios modeled by the IEA (2023c). The range between the current CMM abatement and the adoption ceiling is shown in Table 7.

Additional Benefits

Air Quality and Health

Around 10% of anthropogenic methane comes from coal mines (IEA, 2024a). Methane released from coal mines contributes to ground-level ozone pollution, which can harm lung function, exacerbating conditions like asthma, bronchitis, and emphysema, and can contribute to premature mortality (Mar et al., 2022). Domingo et al. (2024) estimated that ground-level ozone accounted for about 6,600 excess deaths per year in about 400 cities globally. 

Methane released from coal mines also endangers workers’ safety in the mines, increasing the possibility of explosions, which are a significant source of fatalities and injuries (CDC, 2024). In the United States, from 2006 to 2011, mine explosions were responsible for about 25% of fatalities in the mining industry (CDC, 2024). While advances in methane mitigation technologies can prevent explosions and fatalities, mines across LMICs usually do not have methane mitigation protocols in place. Installing methane abatement strategies can potentially protect workers from such explosions (Tate, 2022).

Food Security 

Methane reacts with chemicals like VOCs to form tropospheric, or ground-level ozone (Fiore et al., 2002). Ground-level ozone has been linked to reduced crop growth and yields (Mills et al., 2018; Samperdo et al., 2023; Tai et al., 2021). Mitigating methane emissions from coal mines could improve food security by reducing ground-level ozone and its harmful impacts on agricultural productivity (Tai et al., 2014; Ramya et al., 2023).

left_text_column_width
Risks

CMM abatement strategies could be implemented on a voluntary basis due to favorable natural gas prices, but if natural gas prices drop there is less economic incentive to abate methane (IEA, 2021). Without policy support enforcing methane abatement, emissions could continue, especially from VAM and AMM, which are more difficult to capture and use. Ensuring long-term monitoring and abatement of CMM can be challenging if coal mines are abandoned due to owners going bankrupt, leaving environmental damages unpaid for and remediation up to nearby communities or taxpayers (Ward et al., 2023).

Interactions with Other Solutions

Reinforcing

Managing coal methane can have a positive impact on other solutions that reduce methane release to the atmosphere. The use of technologies such as degasification systems, methane destruction, and Leak Detection and Repair (LDAR) in the coal mine sector can demonstrate the effectiveness and economic case for employing methane abatement. This would build momentum for the widespread adoption of methane abatement because successes in the coal sector can be leveraged and applied to other sectors. In addition, LDAR is a key part in identifying where we can abate methane emissions and lessons learned from the coal sector can be applied to other sites, as well as identifying methane leaks in general.

Competing

CMM management interacts negatively with solutions that provide clean electricity as this solution captures methane that can be used as an energy source, prolonging the use of natural gas infrastructure and reducing the cost of methane as a fuel source.

Trade-offs

Methane abatement strategies are a powerful tool to reduce methane emissions; however, providing a secondary source of revenue for coal mining could increase the profitability and longevity of some coal mines. A broad strategy to reduce reliance on coal as an energy resource is needed to reduce the amount of CMM generated. Even with methane abatement strategies in place, methane used as a fuel or destroyed through flaring will still emit GHGs and contribute to global climate change.

Annual emissions from coal mine sources, 2024

Globally, coal mines are responsible for 40 of the 354 Mt of anthropogenic methane emissions in 2024. This is equivalent to 1,116 Mt CO2-eq based on a 100-year GWP time scale. Methane emissions occur throughout the life of a coal mine and can continue after mines are closed or abandoned.

Annual emissions from coal mine sources, 2024

Globally, coal mines are responsible for 40 of the 354 Mt of anthropogenic methane emissions in 2024. This is equivalent to 1,116 Mt CO2-eq based on a 100-year GWP time scale. Methane emissions occur throughout the life of a coal mine and can continue after mines are closed or abandoned.

Maps Introduction

Coal mine methane abatement is applicable in any area with coal mines. While China and the United States are the largest coal producers, Russia, Ukraine, Kazakhstan, and India also generated more than 10 Mt CO₂‑eq (100-yr) from coal mines in 2015 (GMI, 2015).

Levels of methane emissions from coal mines can vary geographically. The greatest abatement potential is in China, Kazakhstan, Australia, and several countries in Eastern Europe and Africa (Shindell et al., 2024). However, methane abatement is recommended for all coal mining activities, and high-income countries are in a position to share supportive technologies and practices for coal mine methane abatement with other coal-producing countries to reduce methane emissions from active and abandoned or closed mines.

Consensus of effectiveness of abating methane emissions from coal mines: High

There is a high level of consensus about the effectiveness of methane abatement strategies. These strategies can be deployed cost effectively in many cases and have an immediate impact on reducing global temperature rise. 

Authoritative sources such as the IEA (2024c) and UNEP (2021) agree that reducing methane emissions can noticeably slow global climate change. Methane is a short-lived climate pollutant that has a much stronger warming effect than CO₂ over a given time period. IEA (2023d) identified that close to 55% (22 Mt) of CMM emissions could be abated with existing technologies. However, there are significant challenges in measuring and recovering methane emissions in the coal sector. Analysis from Assan & Whittle (2023) found that global CMM emissions could be significantly higher than reported, 38–67 Mt/yr compared with the 40 Mt/yr reported by the IEA (2025).

The IEA (2023a) noted that more than half of CMM emissions could be abated through utilization, flaring, or oxidation technologies, with abatement being more practical for underground mines. Many studies (DeFabrizio et al., 2021; Malley et al., 2023; Shindell et al., 2024) have shown that methane abatement strategies can use existing technologies, often at low cost. In some countries, coal operators already identify the location and sources of CMM to meet health and safety regulations (Assan & Whittle, 2023); Setiawan & Wright (2024) noted that existing technologies such as pre-mine drainage and VAM mitigation have been proven in various places around the world over the past 25 years. According to UNEP (2021), coal methane abatement could reduce emissions by 12–25 Mt/yr, with up to 98% of the measures implemented at low cost. However, costs may vary significantly based on the available infrastructure and characteristics of an individual coal mine.

The results presented in this document summarize findings from 21 reviews and meta-analyses and 20 original studies reflecting current evidence from three countries (Australia, China, and the United States) as well as from sources examining global CMM emissions. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.

CMM abatement strategy constraints:

The type of coal mine, the amount of methane produced, and the available infrastructure greatly affect which abatement strategies are economical. Underground coal mines often produce more CMM and are likely to capture CMM using degasification systems and use it for productive purposes such as electricity generation or selling captured methane. However, VAM, which is a major part of CMM emissions, can be challenging to use for productive purposes due to the low methane concentrations. VAM requires regenerative thermal oxidation technology to effectively destroy and with more gassy coal mines. According to the IEA (2023b), technologies such as flaring and drained CMM can be used at less gassy mines with lower initial capital cost. Capturing methane for destruction has the disadvantage of not creating a source of revenue to offset the capital cost of methane abatement without a form of carbon markets in place. 

More than 60% of methane-related emissions from coal mining are from the ventilation of underground coal mines. Large amounts of fresh air are used to lower the concentration of methane and reduce the risk of explosions in underground mines. This makes it challenging to destroy or use the low concentrations of VAM (UNEP, 2022). It is also challenging to capture methane from surface mines because the coal is in direct contact with the atmosphere and over a larger surface area. However, thermal oxidation systems have been used to destroy VAM (U.S. EPA, 2019) and there have been examples of degasification systems used for surface mines as well (IEA, 2023b). Methane emissions from AMM can be dealt with by flooding underground mines with water (Kholod et al., 2020) or by sealing and using capture and utilization projects (Zhu et al., 2023). 

Technologies for reducing methane emissions can be divided between underground and surface coal mines:

Underground mines
  • Predainage prior to mining
  • VAM capture and utilization
  • Capture of abandoned mine gas
  • Sealing or flooding of abandoned mines 
Surface mines
  • Degasification of surface mines
  • Predrainage of surface mines

Summary

Electric cars are four-wheeled passenger cars that run on electricity, usually from the electricity grid and stored in onboard batteries (i.e., not including fuel cell electric cars). This definition includes electric pickup trucks, motorhomes, and other such vehicles. It does not include two-wheeled vehicles or hybrid cars (which combine an electric motor with a gasoline or diesel engine). It also does not include freight and commercial vehicles, such as electric heavy trucks, buses, and ambulances. We define Mobilizing Electric Cars as replacing fossil fuel–powered cars (i.e., those powered by internal combustion engines) with electric equivalents, as well as building out the necessary infrastructure (especially charging stations) to support them.

Overview

Electric cars provide the same functionality as fossil fuel–powered cars, but use electric motors rather than fuel-burning engines. The energy for the motors comes from an onboard battery, which is normally charged using electricity from the grid.

Electric cars have no direct tailpipe emissions, since electric motors do not burn fuel to function. The grid electricity used to charge their batteries may have come from fossil fuel-burning power plants, meaning electric cars are not entirely free of direct emissions. However, in most electrical grids, even those that mainly generate electricity from fossil fuels, electric cars usually still produce fewer emissions per pkm than fossil fuel–powered cars. This is for three reasons. First, large, fixed power plants and efficient electric grids can convert fossil fuels into useful energy more efficiently than smaller, mobile internal combustion engines in cars. In extreme cases, such as grids powered entirely by coal, this might not be the case, particularly if the grid has a lot of transmission and distribution losses. Second, the powertrain of an electric car delivers electricity from the battery to the wheels much more efficiently than the powertrain of a fossil fuel–powered car, which wastes much more energy as heat (International Transport Forum, 2020; Mofolasayo, 2023; Verma et al., 2022). Third, electric cars’ powertrains enable regenerative braking, where the kinetic energy of the car’s motion is put back into the battery when the driver brakes (Yang et al., 2024).

Electric cars reduce emissions of CO₂,  methane, and nitrous oxide to the atmosphere by replacing fuel-powered cars, which emit these gases from their tailpipes.

Effectiveness

Every million pkm shifted from fossil fuel–powered cars to electric cars reduces 48.52 t CO₂‑eq on a 100-yr basis (Table 1), or 49.13 t CO₂‑eq on a 20-yr basis. 

We found this by collecting data on electricity consumption for a range of electric car models (Electric Vehicle Database, 2024) and multiplying it by the global average emissions per kWh of electricity generation. Fossil fuel–powered cars emit 115.3 t CO₂‑eq/pkm on a 100-yr basis (116.4 t CO₂‑eq/pkm on a 20-yr basis). Electric cars already have lower emissions in countries with large shares of renewable, nuclear, or hydropower generation in their electricity grids (International Transport Forum, 2020; Verma et al., 2022).

These data come disproportionately from North America and Europe, and, notably, leave out China, which has made major progress on electric cars in recent years and has many of its own makes and models. 

Electric cars today are disproportionately used in high- and upper-middle-income countries, whose electricity grids emit fewer GHG emissions than the global average per unit of electricity generated (IEA, 2024). Electric cars in use today reduce more emissions on average than the figure we have calculated. 

Electric cars have higher embodied emissions than fossil fuel–powered cars, due to the GHG-intensive process of manufacturing batteries. This gives them a carbon payback period which ranges from zero to over 10 years (Dillman et al., 2020; Ren et al., 2023).

Cost

Including purchase price, financing, fuel and electricity costs, maintenance costs, and insurance, electric cars cost on average US$0.05 less per pkm (US$49,442.19/million pkm) than fuel-powered cars. This is based on a population-weighted average of the cost differential between electric and fossil fuel–powered cars in seven countries: Japan, South Korea, China, the United States, France, Germany, and the United Kingdom (Nickel Institute, 2021b, 2021c, 2021a). 

While this analysis found that electric cars are less expensive than fossil fuel–powered cars almost everywhere, the margin is often quite small. The difference is less than US$0.01/pkm (US$10,000/million pkm) in South Korea, the United States, and Germany. In some markets, electric cars are more expensive per pkm than fossil fuel–powered cars (IEA, 2022).

This amounts to savings of US$1,019/t CO₂‑eq on a 100-yr basis (Table 2), or US$1,006/t CO₂‑eq avoided emissions on a 20-yr basis). 

Our analysis does not include costs that are the same for both electric and fossil fuel–powered cars, including taxes, insurance costs, and public costs of building road infrastructure.

Learning Curve

For every doubling in electric car production, costs decline by approximately 23% (Table 3; Goetzel & Hasanuzzaman, 2022; Kittner et al., 2020; Weiss et al., 2015). 

In addition to manufacturing improvements and economies of scale, this reflects rapid technological advancements in battery production, which is a significant cost component of an electric powertrain (Weiss et al., 2015).

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as gradual, emergency brake, or delayed.

Mobilize Electric Cars is a GRADUAL climate solution. It has a steady, linear impact on the atmosphere. The cumulative effect over time builds as a straight line.

Caveats

The effectiveness of electric cars in mitigating GHG emissions is critically dependent on the emissions associated with electricity production. In electricity grids dominated by fossil fuels, electric cars have far higher emissions than in jurisdictions with low-emission electricity generation (International Transport Forum, 2020; IPCC, 2022; Milovanoff et al., 2020).

Electric car adoption faces a major obstacle in the form of constraints on battery production. While electric car battery production is being aggressively upscaled (IEA, 2024), building enough batteries to replace a significant fraction of fossil fuel–powered cars is an enormous challenge and will likely slow down a transition to electric cars, even if there is very high consumer demand (Milovanoff et al., 2020). 

left_text_column_width
Current Adoption

Approximately 28 million electric cars are in use worldwide (IEA, 2024). This corresponds to about 819,000 million pkm traveled by electric car worldwide each year (Table 4). We assume that all of this travel would be undertaken by a fossil fuel–powered car if the car’s occupants did not use an electric car. Adoption is much higher in some countries, such as Norway, where the share of electric cars was 29% in 2023.

To convert the IEA’s electric car estimates into pkm traveled, we needed to determine the average passenger-distance that each passenger car travels per year. Using population-weighted data from several different countries, the average car carries 1.5 people and travels an average of 29,250 pkm/yr. Multiplying this number by the number of electric cars in use gives the total travel distance shift from fossil fuel–powered cars to electric cars.

Adoption Trend

Globally, about 104 billion pkm are displaced from fossil fuel–powered cars by electric cars every year (Table 5). The number of new electric cars purchased each year is growing at an average rate of over 10% (Bloomberg New Energy Finance, 2024; IEA, 2024), although purchase rates have declined slightly from record highs between 2020–2022. Global purchases of electric cars are still increasing by around 3.6 million cars/yr. This is based on globally representative data (Bloomberg New Energy Finance, 2024; IEA, 2024).

Despite this impressive rate of growth, electric cars still have a long way to go before they replace a large percentage of the more than 2 billion cars currently driven (WHO, 2024).

Adoption Ceiling

The adoption ceiling for electric cars is equal to the total passenger-distance driven by the more than 2 billion cars worldwide (WHO, 2024). Using a population-weighted mean of the average distance (in pkm) traveled per car annually, this translates to about 59 trillion pkm (Table 6).

Replacing every single fossil fuel–powered car with an electric car would require an enormous upscaling of electric car production capacity, rapid development of charging infrastructure, cost reductions to increase affordability, and technological improvements to improve suitability for more kinds of drivers and trips. It would also face cultural obstacles from drivers who are attached to fossil fuel–powered cars (Roberts, 2022).

Achievable Adoption

The achievable adoption of electric car travel ranges from about 26–47 trillion pkm displaced from fossil fuel–powered cars (Table 7).

Various organizations have produced forecasts for electric car adoption. These are not assessments of feasible adoption per se; they are instead trying to predict likely rates of adoption, given various assumptions about the future (Bloomberg New Energy Finance, 2024; IEA, 2024). However, they are useful in that they take a large number of different variables into account to make their estimates. To convert these estimates of future likely adoption into estimates of the achievable adoption range, we apply some assumptions to the numbers in the scenario projections. 

To find a high rate of electric car adoption, we assume that every country could reach the highest rate of adoption projected to occur for any country. Bloomberg New Energy Finance’s (2024) Economic Transition scenario predicts that Norway will reach an 80% electric vehicle stock share by 2040. We therefore set our high adoption rate at 80% worldwide. This corresponds to 1,617 million total electric cars in use, or 47 trillion pkm traveled by electric car. An important caveat is that with a global supply constraint in the production of electric car batteries, per-country adoption rates are somewhat zero-sum. Every electric car purchased in Norway is one that cannot be purchased elsewhere. Therefore, for the whole world to achieve an 80% electric car stock share, global electric car and battery production would have to increase radically. While this might be possible due to technological improvements or radical increases in investment, it should not be taken for granted.

To identify a lower feasible rate of electric car adoption, we simply take the highest estimate for global electric car adoption. Bloomberg’s Economic Transition scenario predicts 44% global electric car adoption by 2050. This corresponds to 890 million electric cars, or 26 trillion pkm.

Electric cars are currently displacing 0.040 Gt CO₂‑eq of GHG emissions from the transportation system on a 20-yr basis (Table 8), or 0.040 Gt CO₂‑eq on a 100-yr basis. 

If electric cars reach 44% of the global car stock share by 2040, as Bloomberg (2024) projects, without any change in the total number of cars on the road, they will displace 1.263 Gt CO₂‑eq GHG emissions on a 100-yr basis (1.279 Gt CO₂‑eq  on a 20-yr basis).

If electric cars globally reach 80% of car stock share, as Bloomberg projects might happen in Norway by 2040, they will displace 2.296 Gt CO₂‑eq GHG emissions on a 100-yr basis (2.325 Gt CO₂‑eq on a 20-yr basis).

If electric cars replace 100% of the global car fleet, they will displace 2.870 Gt CO₂‑eq  GHG emissions on a 100-yr basis (2.906 Gt CO₂‑eq on a 20-yr basis).

These numbers are based on the present-day average emissions intensity from electrical grids in countries with high rates of electric car adoption. If more clean energy is deployed on electricity grids, the total climate impact from electric cars will increase considerably.

Additional Benefits

Air Quality

The adoption of electric cars reduces emissions of air pollutants, including sulfur oxides, sulfur dioxide, and nitrous oxides, and especially carbon monoxide and volatile organic compounds. It has a smaller impact on particulate emissions (Requia et al., 2018). Some air pollution reductions are limited (particularly PM and ozone) due to heavier electric cars and pollution from brakes, tires, and wear on the batteries (Carey, 2023; Jones, 2019).

Water Quality

Substituting electric car charging points for gas stations can eliminate soil and water pollution from leaking underground gas tanks (Yoder, 2023). 

Health

Since electric cars do not have tailpipe emissions, they can mitigate traffic-related air pollution, which is associated with asthma, lung cancer, increased emergency department visits for respiratory disease, and increased mortality (Anenberg et al., 2019; Guarnieri & Balmes, 2014; Pan et al., 2023; Pennington et al., 2024; Requia et al., 2018; Szyszkowicz et al., 2018). Transitioning to electric cars can reduce exposure to air pollution, improve health, and prevent premature mortality (Garcia et al., 2023; Larson et al., 2021; Peters et al., 2020).

The health benefits of adopting electric cars vary spatially and partly depend upon how communities generate electricity (Choma et al., 2020), but there is evidence that they have improved health. A study in California found a reduction in emergency department visits in ZIP codes with an increase in zero-emissions cars (Garcia et al., 2023). By 2050, projections estimate that about 64,000–167,000 deaths could be avoided by adopting electric cars (Larson et al., 2021).

Communities rich in racial and ethnic minorities tend to be located near highways and major traffic corridors and so are disproportionately exposed to air pollution (Kerr et al., 2021). Transitioning to electric cars could improve health in marginalized urban neighborhoods that are located near highways, industry, or ports (Pennington et al., 2024). These benefits depend upon an equitable distribution of electric cars and infrastructure to support the adoption of electric cars (Garcia et al., 2023). Low-income households may not see the same savings from an electric car due to the cost and stability of electricity prices and distance to essential services (Vega-Perkins et al., 2023)

Income & Work

Adopting electric cars can reduce a household’s energy burden, or the proportion of income spent on residential energy (Vega-Perkins et al., 2023). About 90% of United States households that use a car could see a reduction in energy burden by transitioning to an electric car. Money spent to charge electric cars is more likely to stay closer to the local community where electricity is generated, whereas money spent on fossil fuels often benefits oil-producing regions. This benefits local and national economies by improving their trade balance (Melaina et al., 2016).

left_text_column_width
Risks

Mining minerals necessary to produce electric car batteries carries environmental and social risks. This has been associated with significant harms, particularly in lower-income countries that supply many of these minerals (Agusdinata et al., 2018; Sovacool, 2019).

Electric cars might also pose added safety risks due to their higher weight, which means they have longer stopping distances and can cause more significant damage in collisions and to pedestrians and cyclists (Jones, 2019). This risk includes dual-motor electric cars that incorporate two electric motors – one for the front axle and one for the rear – providing all-wheel drive (AWD) capabilities. The addition of a second motor increases the vehicle's weight and complexity, which can lead to higher energy consumption and reduced overall efficiency. Moreover, the increased manufacturing costs associated with dual-motor systems can result in higher purchase prices for consumers (Nguyen et al., 2023). However, this configuration enhances vehicle performance, offering improved acceleration, traction, and handling, particularly in adverse weather conditions, which are valued by some consumers.

Interactions with Other Solutions

Reinforcing

Electric car batteries can potentially be used as stationary batteries for use as energy storage to balance electrical grids, either through vehicle-to-grid (V2G) technology or with degraded electric car batteries being installed in stationary battery farms as a form of reuse (Ravi & Aziz, 2022). 

The effectiveness of electric cars in reducing GHG emissions increases as electricity grids become cleaner, since lower-carbon electricity further reduces the emissions associated with car charging. 

left_text_column_width

Competing

Electric cars compete with heat pumps for electricity. Installing both heat pumps and electric cars could strain the electric grid’s capacity (Fakhrooeian et al., 2024).

left_text_column_width

Scaling up the production of electric cars requires more mining of critical minerals, which could affect ecosystems that are valuable carbon sinks (Agusdinata et al., 2018).

Getting travelers onto bicycles, sidewalks, public transit networks, or smaller electric vehicles (such as electric bicycles) provides a greater climate benefit than getting them into electric cars. There is an opportunity cost to deploying electric cars because those resources could otherwise be used to support these more effective solutions (APEC, 2024).

Trade-offs

Electric car batteries are currently quite emissions-intensive to produce, resulting in high embodied emissions. While the embodied emissions are higher for electric cars than fossil fuel–powered cars, the results are mixed when coupling these with operating emissions. Dillman et al.’s (2020) review of the literature on this topic found that producing the average battery-electric car emits 63% more GHG emissions than the average gasoline-powered car, and 77% more GHG emissions than the average diesel-powered car. Taking their lower tailpipe emissions into account, this gives them a GHG payback period of zero to more than 10 years. In some cases, the emissions payback period is longer than the expected lifespan of the electric car, meaning it will have higher life cycle GHG emissions than a comparable gasoline or diesel-powered car. However, the ITF (2020) found that the lifetime emissions from manufacturing, operation, and infrastructure are lower for electric cars. All of these studies relied on assumptions, including the type of car, size of battery, electricity grid, km/yr, and lifetime. 

There is some criticism against any solution that advocates for car ownership, contending that the focus should be on solutions such as Enhance Public Transit that reduce car ownership and usage. Jones (2019) noted “there is little evidence to suggest that EVs can offer the universal solution that global governments are seeking,” and that efforts to popularize electric cars “may be better directed at creating more efficient public transport systems, rather than supporting personal transportation, if the significant health disbenefits of car use during the past 150 years are to be in any way reduced.”

Milovanoff et al. (2020) offered similar criticism: “Closing the mitigation gap solely with EVs would require more than 350 million on-road EVs (90% of the fleet), half of national electricity demand, and excessive amounts of critical materials to be deployed in 2050. Improving [the] average fuel consumption of fossil fuel–powered vehicles, with stringent standards and weight control, would reduce the requirement for alternative technologies, but is unlikely to fully bridge the mitigation gap. There is therefore a need for a wide range of policies that include measures to reduce vehicle ownership and usage.”

Allocating the limited global battery supply to privately owned electric cars might undermine the deployment of other solutions that also require batteries, but are more effective at avoiding GHG emissions (Castelvecchi, 2021). These could include electric buses, electric rail, and electric bicycles.

Maps Introduction

Electric cars can effectively mitigate climate change in all geographic regions, although there is spatial variability that influences per-pkm effectiveness and potential solution uptake. Effectiveness heavily depends on the carbon intensity of the charging source, which varies greatly between and within countries. The effectiveness of electric cars decreases for larger vehicles, favored in some countries (Jones, 2019; Nguyen et al., 2023).  

The uptake of electric cars can be significantly influenced by socioeconomic factors, including the relative costs of fuels and electricity, the capacity of civil society to provide adequate charging infrastructure, and the availability of subsidies for electric vehicles.

Extreme temperatures can negatively impact vehicle range, both by slowing battery chemistry and increasing energy demands for regulating passenger compartment temperature, which can adversely affect consumers’ perceptions of electric car suitability in locations with such climates (International Council on Clean Transportation, 2024).

Electric cars are most effective in regions with low-carbon electricity grids (International Transport Forum, 2020; Verma et al., 2022). This includes countries with high hydro power (including Iceland, Norway, Sweden, and parts of Canada such as British Columbia and Quebec), nuclear energy (such as France), and renewables (including Portugal, New Zealand, and parts of the United States, including California and some of the Northwest) (IEA, 2024). Electric car adoption is growing rapidly in a number of regions. For future scaling, targeting countries with supportive policies, renewable energy potential, and growing urban populations will deliver the greatest climate benefits.

Evidence Base

Consensus of effectiveness in reducing emissions: Mixed

There is a high level of consensus among major organizations and researchers working on climate solutions that electric cars offer a substantial reduction in GHG emissions compared to fossil fuel–powered cars. This advantage is strongest in places where electricity in the grid comes from sources with low GHG emissions, but it persists even if fossil fuels play a major role in energy production. 

Major climate research organizations generally see electric cars as the primary means of reducing GHG emissions from passenger transportation. This perspective has received criticism from some scholars who argue that electric cars have been overstated as a climate solution, pointing to supply constraints, embodied emissions, and emissions from electricity generation (Jones, 2019; Milovanoff et al., 2020). Embodied emissions are outside the scope of this assessment. 

The Intergovernmental Panel on Climate Change (IPCC) (2022) estimated well-to-wheel (upstream and downstream emissions) GHG emissions intensity from gasoline and diesel cars at 139 g CO₂‑eq/pkm and 107 g CO₂‑eq/pkm, respectively. They estimated that electric cars running on low-carbon electricity (solar, wind, and nuclear sourced) emit 9 g CO₂‑eq/pkm; electric cars running on natural gas electricity emit 104 g CO₂‑eq/pkm; and electric cars running entirely on coal electricity emit 187 g CO₂‑eq/pkm. These estimates include upstream emissions, such as those from oil refining and coal mining.

The International Energy Agency (IEA, 2024) noted that “[a] battery electric car sold in 2023 will emit half as much as fossil fuel–powered equivalents over its lifetime. This includes full life-cycle emissions, including those from producing the car.” 

The International Transport Forum (ITF) (2020) estimated that fossil fuel–powered cars emit 162 g CO₂‑eq/pkm, while electric cars emit 125 g CO₂‑eq/pkm. This included embodied and upstream emissions, which are outside the scope of this assessment.

The results presented in this document summarize findings from 15 reviews and meta-analyses and 24 original studies reflecting current evidence from 52 countries, primarily the IEA’s Electric Vehicle Outlook 2024), the Electric Vehicle Database 2024), the International Transportation Forum’s life cycle analysis on sustainable transportation 2020), the Nickel Institute’s cost estimates on electric cars (Nickel Institute, 2021b, 2021c, 2021a). We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.

Summary

We define the Mobilize Electric Bicycles solution as increased travel by bicycles that have an electric motor to supplement the effort of the rider, but require the rider to turn the pedals to activate the motor. Some sources refer to electric mopeds or motorcycles as electric bicycles, but those modes of transportation fall within Project Drawdown’s Mobilize Electric Scooters & Motorcycles solution and are not covered here. Also known as pedelecs or e-bikes, electric bicycles can be deployed as privately owned electric bicycles or as shared electric bicycles, which are available as part of bicycle sharing networks typically operated at the city level for short-term rental on a per-trip basis.

Overview

Electric bicycles use electric power to supplement the muscular effort of the rider. Like conventional bicycles and other forms of nonmotorized transportation, electric bicycles get some of their motive power from human muscle power, which in turn comes from food calories – a form of closed-loop biomass power with no emissions (see Project Drawdown’s Improve Nonmotorized Transportation solution). Unlike conventional bicycles, however, electric bicycles get added power from electricity, which comes from the grid and is stored in a battery.

This partial reliance on grid electricity, as well as the production of the battery and electric motors, increases the carbon emissions and cost of an electric bicycle compared to those of a conventional bicycle. Nevertheless, electric bicycle emissions remain far lower than the emissions of cars (including electric cars), meaning that every passenger-kilometer (pkm) moved from a car to an electric bicycle achieves significant GHG emissions savings. 

Since the additional electric power enables electric bicycle riders to cover longer distances at greater speeds, climb larger hills, and carry heavier loads – and do it all with substantially less physical effort – electric bicycles can substitute for more car trips than conventional bicycles can. This can amplify electric bicycles’ potential carbon savings relative to conventional bicycles, even if the savings per pkm traveled are lower. Electric bicycles also tend to get used at high rates, and a large proportion of pkm by electric bicycle are pkm that would otherwise have been by car (Bigazzi & Wong, 2020; Bourne et al., 2020; Cairns et al., 2017; Fukushige et al., 2021).

Shared electric bicycles can enhance this effect. The need for docking stations and rebalancing services (i.e., the use of larger vehicles to reposition bicycles to avoid one-way trips that create shortages in some places and surpluses in others) increases the carbon emissions of electric bicycles per pkm compared with private electric bicycles. By renting out electric bicycles one trip at a time, however, bicycle-share systems can make electric bicycles affordable to a larger percentage of the public, further increasing the number of pkm that can be shifted to electric bicycles.

The adoption of electric bicycles reduces emissions of CO₂ and methane from cars by displacing pkm traveled via car. When electric bicycles replace a trip by a gasoline- or diesel-powered car, they also eliminate reliance on fossil fuels to complete that trip. Even if the electricity used to power electric bicycles comes from fossil fuels, those emissions are relatively small and could eventually be replaced with low-emission electricity through the deployment of renewables or similar technologies.

Effectiveness

Per 1,000 private electric bicycles, approximately 110.5 t CO₂‑eq/yr is offset by displacing trips taken by higher-emission transportation modes such as cars and public transit (Table 1a). 

Per 1,000 shared electric bicycles, approximately 14.44 t CO₂‑eq/yr is offset (Table 1b). This lower value is due to the additional emissions produced in the operation of a shared electric-bicycle system (e.g., due to the need to reposition bicycles after they accumulate in some locations while becoming depleted in others). Additionally, other modes of transportation are shifted to shared electric bicycles at different rates than privately owned electric bicycles – notably shifted less from car travel. These factors limit the total GHG emissions reduced per shared electric bicycle.

Cost

Electric bicycles vary significantly in cost, but generally are more expensive than traditional bicycles due to the cost of batteries, motors, and other electronic components, as well as the need for more durable mechanical components. 

Private electric bicycles cost about US$2,700, plus another few hundred dollars per year in maintenance costs. All told, assuming a 10-year lifespan, electric bicycles cost about US$600/yr to operate . The average privately owned electric bicycle is ridden 2,400 km/yr; since 28.67% of that distance is shifted from car trips, electric bicycles displace approximately 688 pkm/yr traveled by car. Car travel costs US$0.53/pkm while electric bicycle travel costs US$0.25/pkm, meaning every pkm traveled via electric bicycle saves US$0.28. Multiplied over 688 pkm/yr, this translates to every electric bicycle saving its owner approximately US$193/yr in avoided car trips (Bucher et al., 2019; Carracedo & Mostofi, 2022; eBicycles, 2025a; Ebike Canada, 2025; Gössling et al., 2019; Helton, 2025; Huang et al., 2022; International Transport Forum, 2020; Jones, 2019; Luxe Digital, 2025; Mellino et al., 2017; N, 2023; So, 2024; Weiss et al., 2015).

Most of the costs of riding an electric bicycle are up-front costs. As a result, electric bicycle owners who shift more trips from a car onto their electric bicycle will significantly increase their savings. Privately owned electric bicycles save US$1,748 for every t CO₂‑eq they avoid (Table 2a).

Shared electric bicycles are more expensive to the system provider than privately owned electric bicycles due to greater needs for infrastructure, maintenance, operating expenses, and services, such as rebalancing. Shared electric bicycles cost US$2.42/pkm and displace an average of 156 pkm/yr from car trips per bicycle. The same distance traveled by car costs US$83, meaning that shared electric bicycles cost an additional US$295/yr compared to traveling the same distance by car (Gössling et al., 2019; Guidon et al., 2018; Hanna, 2023; Matasyan, 2015; Summit Bike Share, 2023). Shared electric bicycles cost US$22,860/t CO₂‑eq avoided due to their higher costs, higher emissions, and the lower chance that riders on shared electric bicycles would otherwise have been traveling by car (Table 2b).

Learning Curve

Learning rates for electric bicycles are often negative (i.e., prices increase with cumulative production). This is largely because electric bicycle batteries have grown larger over time, causing the bicycles to become more expensive (Dekker, 2013; Weiss et al., 2015). The learning rate per electric bicycle ranges from 15% to –43% (Table 3a). This range has improved the general value proposition of electric bicycles, however, since larger batteries enable electric bicycles to go further and faster than before.

To compensate for this, it is useful to calculate the learning rate per kWh battery capacity rather than per bicycle. On this measure, Dekker (2013) calculates a learning rate of 7.9% cost reduction per kWh of electric bicycle battery capacity for every doubling of cumulative production (Table 3b).

These estimates are based on analyses published in 2013 and 2015, respectively, and therefore do not take into account more recent advances in electric bicycle production. More up-to-date research on electric bicycle learning rates is needed to inform future assessments on this topic.

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as gradual, emergency brake, or delayed.

Mobilize Electric Bicycles is a GRADUAL climate solution. It has a steady, linear impact on the atmosphere. The cumulative effect over time builds as a straight line.

Caveats

Electric bicycles do not only compete with cars for the total passenger transport demand; a given electric bicycle trip might also substitute for public transit. This can sometimes still be beneficial since, as electric bicycles often have lower per-kilometer emissions than public transit vehicles (International Transport Forum, 2020). However, an electric bicycle trip might also substitute for a conventional bicycle trip or for a pedestrian journey, in which case electric bicycle usage would actually increase emissions. Finally, some electric bicycle trips are new journeys, meaning that they would not occur at all if the traveler did not have an electric bicycle, which also increases emissions (Astegiano et al., 2019; Berjisian & Bigazzi, 2019; Bourne et al., 2020; Cairns et al., 2017; Dekker, 2013).

Generally speaking however, electric bicycles still shift enough passenger car trips to make up for this effect, although the scale can be more marginal with shared electric bicycle systems. However, electric bicycles are more likely to substitute more for whichever forms of transportation their users were already using previously (Wamburu et al., 2021). This means that wider adoption of electric bicycles in car-dependent North American suburbs, for example, will have a much clearer and more beneficial climate impact than in a dense, pedestrianized European city center, or in a low-income country where most people do not have access to a car (although in these contexts electric bicycles could still produce major social and economic benefits).

Our estimates of the total adoption ceiling potential of electric bicycles (described in the Adoption section) are based on the ratio of adoption between electric bicycles and cars, on the grounds that each electric bicycle avoids some amount of car travel. However, the relationship is not necessarily quite so simple. Car trips with passengers might require more than one electric bicycle trip to replace them (unless the passengers are children, who can be carried as passengers on electric bicycles). On the other side of the equation, some households own more than one car per person. Having more than one electric bicycle per car would therefore not meaningfully reduce car trips. Lastly, our approach of tracking electric bicycle adoption in relation to car ownership neglects people whose use of an electric bicycle enables them to avoid owning a car at all. Estimates of adoption should be taken as rough guesses, rather than authoritative forecasts.

Current Adoption

Private electric bicycles have experienced significant growth since 2015. We estimate there are approximately 278 million private electric bicycles in use in the world today (Table 4a). 

Data on this subject typically include throttle-assisted electric bicycles, e-scooter/trotinettes, and sometimes mopeds and motorcycles; these are not included in this solution. Data from China, the highest adopter of electric bicycles, does not usually distinguish between types of electric two-wheelers. For this reason, we used more conservative estimates, preferring to understate adoption than overstate it. We used several global estimates, data on electric bicycle sales in Canada, the United States, and Europe, and stock estimates from the Asia-Pacific region (eBicycles, 2025b; Mordor Intelligence, 2022; Precedence Research, 2024; Stewart & Ramachandran, 2022; Strategic Market Research, 2024; The Freedonia Group, 2024). To convert from European and American sales data to stocks data, we assumed that all electric bicycles sold over the past 10 years (the lifespan of an electric bicycle) are still in use today. We then calculated the number of electric bicycles per 1,000 people in each of the three regions, used those three values to calculate a population-weighted global mean adoption rate, and multiplied the result by the number of residents of high- and upper-middle income countries worldwide (where we assume most electric bicycle adoption takes place). This calculation provided a global estimate.

Shared electric bicycle schemes now exist in many cities around the world, with at least 2 million shared electric bicycles currently in use as part of electric bicycle sharing systems (Table 4b; eBicycles, 2025b; Innovation Origins, 2023; PBSC Urban Solutions, 2022; Strategic Market Research, 2024). This is a conservative estimate because research published in a reputable academic journal claimed that China has 8.7 million shared electric bicycles in 2022 (Shi et al., 2024).

Adoption Trend

Private electric bicycles are being adopted at a rate of about 37 million new bicycles every year (Table 5a; eBicycles, 2025b; Mordor Intelligence, 2022; Precedence Research, 2024; Stewart & Ramachandran, 2022; Strategic Market Research, 2024; The Freedonia Group, 2024). Electric bicycles are also attracting interest from consumers who do not normally ride bicycles, including people in rural areas (Philips et al., 2022) and members of vulnerable groups, such as the elderly. 

Shared electric bicycles are being added to cities at a rate of approximately 413,000/yr (Table 5b; eBicycles, 2025b; Innovation Origins, 2023; PBSC Urban Solutions, 2022; Strategic Market Research, 2024). Cities and private companies are adding shared electric bicycle systems at a rate of around 30/yr (Galatoulas et al., 2020). Based on these data, we calculate a 37.97% compounding annual growth rate in electric bicycle sharing system installations around the world.

Adoption Ceiling

Because we model electric bicycles as a solution primarily due to their ability to shift travel from fossil fuel–powered cars, we estimate adoption by reference to the ratio of electric bicycles to cars. This does not mean that people without access to a car will not use electric bicycles; it means that they are not shifting their pkm from fossil fuel–powered cars and therefore are not included in the calculations of shifting from car to electric bicycle. 

Private electric bicycles’ adoption ceiling (Table 6a) would be approximately 2 billion around the world: one for every car (World Health Organization, 2021). This would mean that every motorist has an electric bicycle as a ready alternative to a car.

Shared electric bicycles’ adoption ceiling can be measured similarly, except that we assume these systems are only viable in cities. Therefore, we set the maximum adoption ceiling of shared electric bicycles to be 1.3 billion (Table 6b) – the number of cars in cities around the world. we estimated by multiplying the global urban population (4.45 billion) by the global average car registrations per 1,000 people (286.2) (World Health Organization, 2021; World Bank, 2024).

This upper-bound scenario faces many of the same caveats as the upper-bound scenario for the Improve Nonmotorized Transportation solution. It would require a revolution in support for electric bicycles: new infrastructure, new traffic laws, a substantial increase in electric battery production capacity, and major changes to built environments, including increases in population and land-use density to make more journeys feasible by electric bicycle. However, this scenario would require less dramatic change than a similar upper-bound scenario for the Improve Nonmotorized Transportation solution because electric bicycles go faster, have higher carrying capacities, can travel longer distances, and are easier to use than nonmotorized travel modes (Weiss et al., 2015).

A limitation of this analysis is that one electric bicycle per car does not necessarily correspond to one electric bicycle per person traveling in a car. For example, it is possible that replacing one car trip with electric bicycles would result in multiple electric bicycle trips in order to carry multiple passengers. Our estimates should therefore be seen as approximate. 

It is also possible for total electric bicycle adoption and usage to exceed car use (i.e., electric bicycles also replace other modes of transportation or generate new trips). We do not consider this scenario in our adoption ceiling because additional adoption above car adoption would not produce a major climate benefit.

Achievable Adoption

Private electric bicycles are currently in use across the Asia-Pacific region at a rate of approximately 0.07 electric bicycles for every car. A low achievable adoption rate might see every country in the world achieve this same ratio, which would lead to a global electric bicycle fleet of 421 million (Table 7a). For a higher rate of adoption, we posit one electric bicycle in use for every two cars. This would see just more than 1 billion electric bicycles in use worldwide.

Using the median and 75th percentile of the ratio of shared electric bicycles to cars (for which we have data) as the rate of adoption seen in every city in the world leads to 22 to 69 million shared electric bicycles in cities worldwide (Table 7b).

Note: We based these estimates on electric bicycles per car rather than electric bicycles per person because the climate impact of electric bicycle adoption in a given place depends on the availability of cars to replace.

If every motorist had an electric bicycle they used to replace at least some car trips, it would mitigate 224 Mt CO₂‑eq/yr – equal to the total global carbon emissions produced by cars, minus the emissions that would be produced due to electric bicycles traveling the same distance. If there were one electric bicycle for every two cars, it would avoid 117 Mt CO₂‑eq/yr. And if global electric bicycle adoption reached the rate currently seen in the Asia-Pacific region (China, India, Japan, South Korea, Australia, and New Zealand), it would avoid 47 Mt CO₂‑eq/yr (Table 8a).

Our Achievable – Low scenario of 22 million shared electric bicycles in cities worldwide would save 284 kt CO₂‑eq/yr (Table 8b). Our Achievable – High scenario of 69.3 million shared electric bicycles worldwide would save 895 kt CO₂‑eq/yr. The maximum possible shared electric bicycle deployment would save approximately 16.6 Mt CO₂‑eq/yr.

Additional Benefits

Health

Electric bicycles provide quality-of-life benefits for some people who use them (Bourne, 2020; Carracedo & Mostofi, 2022; Teixeira et al., 2022; Thomas, 2022). Electric assistance reduces the physical fitness and other health benefits of cycling. However, electric bicycles still require pedaling, and studies show that this level of effort required can still have substantial health benefits (Berjisian & Bigazzii, 2019; Langford et al., 2017). Electric bicycles can also enable people to cycle who might not otherwise be able to (Bourne et al., 2020). Additionally, electric bicycles can reduce total car traffic, which could reduce the risk of injury and death from car crashes, which kill 1.2 million people annually (WHO, 2023). Similarly, electric bicycles can reduce health impacts of traffic noise (de Nazelle et al., 2011).

Income and Work

In addition to being cheaper than car travel, electric bicycles allow people to travel farther and faster than they could on foot, on a conventional bicycle, or (often) on public transit. Time savings from quick, longer trips, reduced traffic congestion, and money savings provide an economic benefit (Bourne, 2020). 

Air Quality

The fossil fuel–powered vehicles most similar to electric bicycles (motorcycles, scooters, etc.) are extremely polluting (Platt et al., 2014). Substituting electric bicycles for these can substantially reduce air pollution.

left_text_column_width
Risks

Electric bicycles pose some safety concerns, centering on an ongoing debate over whether electric cyclists ride more recklessly than other cyclists (Fishman & Cherry, 2016; Langford et al., 2015). While electric bicycles have a lower injury rate than conventional bicycles, when injuries do happen during electric bicycle travel the health consequences tend to be more severe due to the higher speed (Berjisian & Bigazzi, 2019). There may also be risks related to the bicycles’ lithium-ion batteries catching fire. Strong regulations can minimize this risk (Pekow, 2024). Improved infrastructure, such as separated bike lanes and paths, can also reduce the safety risks associated with electric bicycles (Roberts, 2020).

Interactions with Other Solutions

Reinforcing

Electric bicycles can complement other forms of low-carbon mobility, especially those that reduce dependence on private cars. People who rely on public transit, conventional travel, pedestrian travel, carpools, or other sustainable modes of transportation for some kinds of trips can use electric bicycles to fill in some of the gaps in their personal transportation arrangements (Roberts, 2023). For public transit in particular, electric bicycles can play an important last-mile role, enabling transit riders to more easily access stops. This is important because research suggests that the key to a low-carbon mobility system is to enable people to live high-quality lives without owning cars (Van Acker & Witlox, 2010).

left_text_column_width

Electric bicycles require a lot less space than private cars. If sufficient adoption of electric bicycles and other alternatives to private cars enables a reduction in car lanes, parking spaces, and related infrastructure, then some of this space could be reallocated to ecosystem conservation through revegetation and other land-based methods of GHG sequestration (Rodriguez Mendez et al., 2024).

Trade-offs

If an electric bicycle replaces primarily car trips, it provides an unambiguous climate benefit. If it replaces public transit, the size of the benefit will depend on the specifics of the public transit system it replaces. If it replaces pedestrian trips or conventional cycling trips, or generates new trips, the net climate benefit is negative. Travel survey data suggest that electric bicycles replace enough car journeys to more than offset any journeys by the more sustainable modes of transportation they replace (Bigazzi & Wong, 2020; Bourne et al., 2020; Cairns et al., 2017; Fukushige et al., 2021). However, electric bicycles in cities that already have very low-carbon mobility systems, or in lower-income countries where car ownership is rare, might have a net negative climate impact. 

Electric bicycles also require batteries, the production and disposal of which generates pollution (Yang et al., 2021). However, electric bicycles require much less battery capacity than many other electrification technologies, such as electric vehicles (Weiss et al., 2015).

Maps Introduction

Electric bicycle effectiveness in mitigating climate change varies by region, depending on the carbon intensity of the charging electricity, the extent to which they replace higher-emission travel (such as cars, motorcycles, or taxis), and the need and type of vehicle used for rebalancing shared electric bicycles (International Transport Forum, 2020). They are most effective in areas with cleaner electricity grids and where they can substitute for cars. 

Since electric bicycles are more effective when replacing cars, this means that wider adoption of electric bicycles in car-dependent regions, such as North American suburbs, will have a much more significant climate impact than in a dense, pedestrianized European city center or in a low-income country where most people do not have access to a car (although in these contexts electric bicycles could still produce significant social and economic benefits) (Wamburu et al., 2021).

Socio-economic and infrastructural factors play a major role in adoption. These include upfront costs of private electric bicycles, availability and affordability of shared electric bicycles, supportive cycling infrastructure, and policies such as subsidies or rebates. In many countries, electric bicycles increase the accessibility of nonmotorized transport to older adults, people with disabilities, and those commuting longer distances or in hilly areas by reducing physical effort (Bourne et al., 2020).

Future geographic targets for scaling adoption with strong climate and equity outcomes include South and Southeast Asian cities (e.g., Dhaka, Jakarta, Ho Chi Minh City) with high trip density, short trip lengths, and growing pollution concerns, all of which make them ideal for adoption. Sub-Saharan African cities (e.g., Kampala, Accra) where electric bicycles could complement or replace informal motorcycle taxis, reducing emissions and improving affordability and safety, are also important targets. North America has potential as both private and shared programs are beginning to expand in urban areas, helped by municipal investment and rising consumer interest.

Evidence Base

Consensus of effectiveness in reducing emissions: High

When people purchase electric bicycles, they tend to use them often, with many of the trips they take on electric bicycles replacing trips that would otherwise have been taken via private car (Bigazzi & Wong, 2020; Bourne et al., 2020; Cairns et al., 2017; Fukushige et al., 2021). The evidence is similarly conclusive regarding the ability of shared electric bicycles to replace a large number of car trips. However, evidence regarding the carbon benefits of shared electric bicycles is more mixed due to the additional emissions required to run a shared electric-bicycle system.

Berjiisian and Bigazzi (2019) reviewed much of the literature on electric bicycles. and found that electric bicycle trips are shifted from car trips (44%) and transit trips (12%) providing significant emissions benefits. Other net benefits include less travel by cars, lower GHG emissions and more physical activity. “E-bike adoption is expected to provide net benefits in the forms of reduced motor vehicle travel, reduced greenhouse gas emissions, and increased physical activity. A little more than half of e-bike trips are expected to shift travel from motor vehicles (44% car trips and 12% transit trips), which is sufficient to provide significant emissions benefits.”

Weiss et al. (2015) surveyed evidence of the economic, social, and environmental impacts of electric bicycles. They found that electric bicycles are more efficient and less polluting than cars. They reduce exposure to pollution as their environmental impacts come mainly from being produced and the electricity that they use, both of which are usually outside of urban areas.

Philips et al. (2022) investigated the potential for electric bicycles to replace car trips in the UK. Their geospatial model provided a good indication of what might be possible in other places and showed that electric bicycles have considerable potential in rural areas as well as urban ones. 

Li et al. (2023) reported that based on the mix of mode share replaced, shared electric bicycle trips decreased carbon emissions by 108–120 g/km carbon emissions than fossil fuel-powered cars per kilometer.”

This research is biased toward high-income countries. While there is substantial research on electric bicycles in China, that country often considers e-scooters (which do not have pedals) and throttle-assisted electric bikes as interchangeable with pedelecs electric bicycles. This made it hard to include Chinese research in our analysis. We recognize this limited geographic scope creates bias, and hope this work inspires research harmonization and data sharing on this topic in underrepresented regions in the future.
