Summary

We define the Deploy Clean Cooking solution as the use of cleaner cooking fuels (liquid petroleum gas, natural gas, electricity, biogas, and ethanol) in place of polluting fuels such as wood, charcoal, dung, kerosene, and coal, and/or the use of efficient cookstove technologies (together called cleaner cooking solutions). Replacing unclean fuel and cookstoves with cleaner approaches can drastically reduce GHG emissions while offering health and biodiversity benefits.

Deploy Clean Cooking is a Highly Recommended climate solution. Cleaner cooking can reduce GHG emissions while offering health and biodiversity benefits, too.
Overview

Worldwide, cooking is responsible for an estimated 1.7 Gt CO₂‑eq/yr (100-yr basis), (World Health Organization [WHO], 2023), or almost 3% of annual global emissions. Most of these emissions come from burning nonrenewable biomass fuels. Only the CO₂‑eq on a 100-yr basis is reported here due to lack of data on the relative contributions of GHGs. The International Energy Agency (IEA, 2023a) states that 2.3 billion people in 128 countries currently cook with coal, charcoal, kerosene, firewood, agricultural waste, or dung over open fires or inefficient cookstoves because they do not have the ability to regularly cook using cleaner cooking solutions. Even when sustainably harvested, biomass fuel is not climate neutral because it emits methane and black carbon (Smith, 2002).

Clean cooking (Figure 1) reduces GHG emissions through three pathways: 

Improving Efficiency

Traditional biomass or charcoal cookstoves are less than 15% efficient (Khavari et al., 2023), meaning most generated heat is lost to the environment rather than heating the cooking vessel and food. Cleaner fuels and technologies can be many times more efficient, using less energy to prepare meals than traditional fuels and cookstoves (Kashyap et al., 2024). 

Reducing Carbon Intensity

Cleaner fuels have lower carbon intensity, producing significantly fewer GHG emissions per unit of heat generated than conventional fuels. Carbon intensity includes CO₂, methane, and nitrous oxide as well as black carbon. For instance, charcoal cookstoves emit approximately 572 kg CO₂‑eq /GJ of heat delivered for cooking (Cashman et al., 2016). In contrast, liquefied petroleum gas (LPG) and biogas emit about 292 and 11 kg CO₂‑eq /GJ, respectively (Cashman et al., 2016) and, excluding the embodied carbon, stoves that heat with electricity generated from renewable energy sources such as solar, wind, or hydroelectric have zero emissions.

Reducing Deforestation

Cleaner cooking also helps mitigate climate change by reducing deforestation (Clean Cooking Alliance [CCA], 2023) and associated GHG emissions.

Effectiveness

The climate impact of cleaner cooking depends on which fuel and technology is being replaced and what is replacing it. The WHO (2023) categorizes cooking fuels as clean, transitional, or polluting based primarily on health impacts. Clean fuels include solar, electric, biogas, LPG, and alcohols, while kerosene and unprocessed coal are polluting fuels. Biomass cooking technologies may be classified as clean, transitional, or polluting depending on the levels of fine particulate matter and carbon monoxide produced. Switching from traditional cookstoves (polluting) to improved cookstoves (transitional) can reduce emissions 20–40%, while switching to an LPG or electric cookstove can reduce emissions more than 60% (Johnson, 2009). Not including the embodied carbon, switching completely to solar-powered electric cookstoves can reduce emissions 100%.

We estimated the effectiveness of cleaner cooking by calculating the reduction in GHG emissions per household switching to cleaner cooking solutions per year (Table 1). Our analysis of national, regional, and global studies suggested that switching to cleaner fuels and technologies can reduce emissions by 0.83–3.4 t CO₂‑eq /household/yr (100-yr basis), including CO₂, methane, black carbon, and sometimes other GHGs. The large range is due to varying assumptions. For example, the IEA arrived at 3.2 t CO₂‑eq /household/yr (100-yr basis) by assuming that >50% of the households switched to electricity or LPG. In comparison, Bailis et al. (2015) assumed a switch from unclean cookstoves to improved biomass cookstoves, resulting in an emissions reduction of only 0.98 t CO₂‑eq /household/yr (100-yr basis).

While we calculated a median reduction of 2.3 t CO₂‑eq /household switching to cleaner cooking solutions/yr (100-yr basis), the actual reduction per household might be lower because households often stack cleaner cooking fuel with unclean fuel. This could result from multiple socioeconomic factors. For instance, a household may primarily rely on LPG as its main cooking fuel but occasionally turn to firewood or kerosene for specific dishes, price fluctuation, or fuel shortages (Khavari et al., 2023). In rural areas, cleaner fuels and traditional biomass (e.g., wood or dung) are used together to cut costs or due to personal preferences.

left_text_column_width
Cost

People can obtain traditional unclean fuels and traditional woodstoves for little or no cost (Bensch et al., 2021; Kapsalyamova et al., 2021). Our analysis estimated the cost of woodstoves at US$1.50/household and the monetary cost of biomass fuel at US$0.00/household/yr. Over the two-yr lifespan of a woodstove, the net annualized cost is US$0.75/household/yr. While collecting this fuel might be free, it contributes to poverty because households can spend one to three hours daily collecting fuelwood. This can contribute to children, especially girls, missing school (Jameel et al., 2022). 

We estimated the median upfront cost of transitioning from primarily unclean cooking fuels and technology to cleaner cooking to be approximately US$58/household, with stoves lasting 3–10 years. However, the range of annual costs is large because several cleaner cooking technologies have significant variations in price, and cleaner fuel cost is even more variable. Our analysis showed a median annual fuel cost of US$56/household/yr with costs ranging from savings of US$9/household/yr when buying less biomass for more efficient biomass stoves to costs of US$187/household/yr for LPG. We estimated that over a five-year lifespan, cleaner cooking solutions have a net cost of US$64/household/yr.

Our analysis may overestimate operational costs due to a lack of data on biomass and charcoal costs. The IEA (2023a) estimates that an annual investment of US$8 billion is needed to supply cleaner cookstoves, equipment, and infrastructure to support a transition to cleaner cooking. This translates to US$17/household/yr. 

The IEA (2023) assumes improved biomass and charcoal cookstoves are predominantly adopted in rural areas while LPG and electric stoves are adopted in urban regions because, in LMICs, economic and infrastructure challenges can limit access to LPG and electricity in rural areas. If every household were to switch exclusively to modern cooking (e.g., LPG and electricity), the cost would be much higher. The World Bank estimates the cost of implementing these solutions to be US$1.5 trillion between 2020 and 2030 or ~US$150 billion/yr over the next 10 years. This translates into an average cost of US$214/household/yr (World Bank, 2020).

The median cost per unit of climate impact was US$28/t CO₂‑eq (100-yr basis, Table 2), obtained by taking the difference between median cost of cooking with polluting sources and the cost of adopting cleaner fuel, then dividing by the median reduction per household (Table 1). Beyond climate benefits, cleaner cooking offers significant other benefits (discussed below). While the median cost presented here is a reasonable first-order estimate, the actual cost of GHG reduction will depend upon several factors, including the type of stove adopted, stove usage, fuel consumption, and scale of adoption.

Learning Curve

Deploying cleaner cooking is a mature technology, and prices are unlikely to decrease in high-income countries where cleaner cooking fuels and technologies have been completely adopted. Nonetheless, the high cost of cleaner cooking technologies and the fluctuating prices of cleaner cooking fuel have been among the main impediments in the transition of households experiencing poverty away from unclean fuels and technologies. For example, recent price surges in Africa rendered LPG unaffordable for 30 million people (IEA, 2022). Electricity prices have also fluctuated regionally. In Europe and India, prices were higher in 2023 than in 2019 (IEA, 2023b). In contrast, U.S. electricity prices have remained stable over the past five years, while China experienced an 8% decrease.

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 emergency brake, gradual, or delayed.

Deploy Clean Cooking 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

Households may continue using unclean cooking fuel and technologies alongside cleaner fuels and technologies (referred to as stacking). The data on cleaner cooking are typically measured as the number of households primarily relying on cleaner cooking fuel. This fails to capture the secondary fuel source used in the household. A review from LMICs revealed that stacking can range from low (28%) to as high as 100%, which would mean that every household is simultaneously using cleaner and unclean fuel (Shankar et al., 2020). This can happen due to factors like an increase in the cost of cleaner cooking fuel, cooking preference, unavailability of cleaner fuel, and unfamiliarity with cleaner cooking technologies. Stacking is challenging to avoid, and there is a growing realization from cleaner cooking practitioners of the need for cleaner approaches, even when multiple stoves are used. For example, electric stoves can be supplemented with LPG or ethanol stoves.

Permanence

There are significant permanence challenges associated with cleaner cooking. Households switch back from cleaner cooking fuels and technologies to unclean fuels and technologies (Jewitt et al., 2020). 

Finance

Finance is vital to supercharge adoption of cleaner cooking. Investment in the cleaner cooking sector remains significantly below the scale of the global challenge, with current funding at approximately US$130 million. This is many times lower than the amount needed each year to expand adoption of cleaner cooking solutions for the 2.4 billion people who still rely on polluting fuels and technologies (CCA 2023). At the current business-as-usual adoption rate, limited by severe underfunding, more than 80% of the population in sub-Saharan Africa will continue to rely on unclean fuels and technologies in 2030 (Stoner et al., 2021)

Climate funding, developmental finance, and subsidies have made some progress in increasing adoption of cleaner cooking. For instance, the World Bank invested more than US$562 million between 2015 and 2020, enabling 43 million people across 30 countries to adopt cleaner cooking solutions (ESMAP, 2023; World Bank, 2023). However, the emissions reductions these programs achieve can be overestimated. A recent analysis (Gill-Wiehl et al., 2024) found that 26.7 million clean cooking offset credits in reality only amounted to about 2.9 million credits. This discrepancy underscores the urgent need for updated methodologies and standards to accurately estimate emissions reductions and the cost of reduction per t CO₂‑eq (100-yr basis).

Current Adoption

The WHO (2025) estimated that 74% of the global population in 2022 used cleaner cooking fuels and technologies. This translates to 1.2 billion households using cleaner cooking (Table 2) and 420 million households that have yet to switch to clean cooking solutions (Table 6). The adoption of cleaner cooking is not evenly spread across the world. On the higher end of the spectrum are the Americas and Europe, where, on average, more than 93% of people primarily rely on cleaner cooking fuels and technologies (WHO, 2025). On the lower end of the spectrum are sub-Saharan countries such as Madagascar, Mali and Uganda, where primary reliance on cleaner cooking fuel and technologies is <5%. While current adoption represents households that enjoy cleaner cooking today, our analysis for achievable adoption and adoption ceiling focuses on quantifying households that currently use traditional cooking methods and can switch to cleaner cooking. 

To calculate climate impact of this solution, we defined the adoption unit as households switching to clean cooking after 2022. For this reason, current adoption in Table 6 and the solution summaries is not determined.

Global adoption of cleaner cooking fuel and technologies as the primary source of cooking increased from 61% of the population in 2013 to 74% in 2023 (WHO, 2025). This translates to roughly 21 million households adopting cleaner cooking technologies/yr (Table 3). This uptake, however, is not evenly distributed (see Maps section above).

Large-scale adoption across China, India, and Indonesia has driven the recent increase. Between 2011 and 2021, use of cleaner fuels and technologies as the primary means of cooking rose from 61% to 83% of the population in China. In India, adoption expanded from 38% to 71%, and in Indonesia, it increased from 47% to 87% (WHO, 2024a). In contrast, primary reliance on cleaner cooking in sub-Saharan Africa only increased from 12% in 2010 to 16% in 2020 (Stoner et al., 2021). 

Based on the existing policies, population growth, and investments, more than 75% of the sub-Saharan African population will use unclean cooking fuels and technologies in 2030 (Stoner et al., 2021). In Central and Southern Asia, about 25% of the population will use unclean cooking fuels and technologies by 2030 (Stoner et al., 2021).

Adoption Ceiling

The World Bank (2020) estimated that universal adoption of modern energy cooking services by 2030 is possible with an annual investment of US$148–156 billion, with 26% of the investment coming from governments and development partners, 7% from private investment, and 67% from households. Universal adoption and use of cleaner fuels and technologies is possible with an investment of US$8–10 billion/yr (IEA, 2023a; World Bank, 2020). We therefore set the adoption ceiling at 100% of households adopting and using cleaner cooking solutions, which entails 420 million households switching from unclean solutions (Table 4).

Achievable Adoption

Universal adoption and use of cleaner cooking solutions is achievable before 2050 (Table 5). This is because if the current adoption trend continues, all households that currently use unclean cooking fuels and technologies will have switched to using cleaner versions by 2043. 

China, India, and Indonesia have shown that it is possible to rapidly expand adoption with the right set of policies and investments. In Indonesia, for example, use of cleaner cooking solutions increased from 9% of the population to 89% between 2002 and 2012 (WHO, 2025).

Cooking from all fuel types is responsible for approximately 1.7 Gt CO₂‑eq (100-yr basis) emissions every year (WHO, 2023), on par with global emissions from the aviation industry (Bergero et al., 2023). Unclean cooking fuels and technologies are also the largest source of black carbon (Climate & Clean Air Coalition, 2024), a short-lived climate pollutant with a GWP several hundred times higher than CO₂ that contributes to millions of premature deaths yearly (Garland et al., 2017). 

The actual reduction in climate impact will depend upon the mix of cleaner fuel and technologies that replace unclean fuel. The IEA (2023a) estimates that if the cleanest cooking fuels and technologies (e.g., electric and LPG) are adopted, emissions could be reduced by 1.5 Gt CO₂‑eq/yr (100-yr basis) by 2030. In contrast, a greater reliance on improved cookstoves as cleaner cooking solutions will result in lower emissions reductions. The WHO (2023) estimates that much of the shift by 2030 will involve using improved biomass and charcoal cookstoves, especially in rural areas, reducing emissions 0.6 Gt CO₂‑eq/yr (100-yr basis) by 2030 and ~1.6 CO₂‑eq/yr (100-yr basis) by 2050, closely matching the IEA estimate.

According to our analysis, deploying cleaner cooking can reduce emissions by 0.98 Gt CO₂‑eq/yr (100-yr basis) between now and 2050 (Table 6). Our emissions reduction estimates are lower than those of the IEA because we do not assume that the shift to cleaner cooking will be dominated by LPG and renewables.

Additional Benefits

Income and Work

Simkovich et al. (2019) found that time gained by switching to cleaner fuel can increase daily income by 3.8–4.7%. Their analysis excludes the expenses related to fuel, as well as the costs associated with delivery or transportation for refilling cleaner fuel. Mazorra et al. (2020) reported that if 50% of the time saved from not gathering firewood were redirected to income-generating activities, it could lead to an estimated annual income increase of approximately US$125 (2023 dollars) in the Gambia, US$113 in Guinea-Bissau, and US$200 in Senegal. Health and Air Quality

Unclean cooking fuels and technologies produce household air pollution (HAP), with smoke and fine particulates sometimes reaching levels up to 100 times acceptable limits, particularly in poorly ventilated spaces (WHO, 2024b). HAP is linked to numerous health issues, such as stroke, ischemic heart disease, chronic obstructive pulmonary disease, lung cancer, and poor birth outcomes (Jameel et al., 2022). It accounts for more than 3.2 million early deaths annually (WHO, 2024b). In 2019, it accounted for over 4% of all the deaths globally (Bennitt et al., 2021). The World Bank (2020) estimated that the negative health impact of unclean cooking fuels and technologies is valued at US$1.4 trillion/yr. Globally, switching to cleaner fuels and technologies could prevent 21 million premature deaths from 2000–2100 (Lacey et al., 2017). A recent study offered empirical evidence of potential cardiovascular benefits stemming from household cleaner energy policies (Lee et al., 2024).

Equality

Unclean cooking disproportionately impacts women and children who are traditionally responsible for collecting fuelwood or biomass. Typically, they spend an hour every day collecting solid fuel; however, in some countries (e.g., Senegal, Niger, and Cameroon), daily average collection time can exceed three hours (Jameel et al., 2022). Time-saving cooking fuels are associated with more education in women and children (Biswas & Das, 2022; Choudhuri & Desai, 2021) and can additionally promote gender equity through economic empowerment by allowing women to pursue additional employment opportunities (CCA, 2023). In conflict zones, adoption of cleaner fuels and technologies has been shown to reduce gender-based violence (Jameel et al., 2022). Finally, cleaner cooking fuels can improve health equity as women are disproportionately exposed to indoor air pollution generated from cooking (Fullerton et al., 2008; Po et al., 2011). 

Nature Protection

The unsustainable harvest of wood for cooking fuel has led to deforestation and biodiversity loss in regions such as South Asia and sub-Saharan Africa (CCA, 2022). East African nations, including Eritrea, Ethiopia, Kenya, and Uganda, are particularly affected by the rapid depletion of sustainable wood fuel resources. In the Democratic Republic of the Congo, 84% of harvested wood is charcoal or firewood (World Bank, 2018). Switching to cleaner cooking fuels and technologies can reduce deforestation and protect biodiversity (Anenberg et al., 2013; CCA, 2022; Dagnachew et al., 2018).

Risks

The expensive nature of cleaner cooking presents a significant barrier to adoption. Households that have recently transitioned to cleaner cooking face a high risk of defaulting back to unclean fuels and technologies. For example, among the households that received free LPG connection as a part of the Pradhan Mantri Ujjwala Yojana in India, low-income households reverted to unclean fuels and technologies during extensive periods of refill gaps (Cabiyo et al., 2020). In total, 9 million recipients could not refill their LPG cylinders even once in 2021–22 due to high LPG costs and other factors (Down to Earth, 2022).

Beyond the cost, there is an adjustment period for the households adopting the cleaner cooking solution, which includes familiarizing themselves with the technology and fostering cultural and behavioral changes, including overcoming biases and adopting new habits.

Interactions with Other Solutions

Reinforcing

This solution also decreases the demand for wood and waste biomass. Because the total projected demand for wood and waste biomass across climate solutions exceeds the supply, reducing demand from clean cooking will help the following solutions increase their potential adoption by increasing the availability of raw agricultural waste and other biomass:

Trade-offs

Switching to electric cooking will meaningfully reduce GHG emissions only if the grid is powered by clean energy. A life-cycle assessment of cooking fuels in India and China (Cashman et al., 2016) showed that unclean cooking fuels such as crop residue and cow dung had a lower carbon footprint than electricity because in these countries >80% of the electricity was produced by coal and natural gas. 

LPG has been the leading cleaner fuel source replacing unclean cooking fuel globally (IEA, 2023a). The IEA (2023a) estimated that 33% of households transitioning to cleaner cooking fuels and technologies will do so using LPG to transition. Because LPG is a fossil fuel, increased reliance can hinder or slow the transition from fossil fuels.

Maps Introduction

The Deploy Clean Cooking solution applies to geographies where low-cost, inefficient, and polluting cooking methods are common. Sub-Saharan Africa is the overwhelming target, with only 23% of the population relying on clean cooking technologies (WHO, 2025). 

There are significant correlations between the lack of clean cooking solutions and levels of extreme poverty (World Bank, 2024). The financial cost of clean fuel and cookstoves is a significant barrier to adoption (WHO, 2023).  

Some of the key benefits of deploying clean cooking will vary based on geography and landscape. For instance, freeing up time spent collecting firewood will be more notable in areas with less dense forest, since people in such locations would have to travel farther to harvest wood (Khavari et al., 2023).

Barriers to the adoption of clean cooking can also vary with geography. Examples noted by Khavari et al. (2023) include robustness of supply chains, which can be influenced by population density and road networks.

Evidence Base

There is a strong consensus on the effectiveness of cleaner cooking as a climate solution. Research over the past two decades (e.g., Anenberg et al., 2013; Mazorra et al., 2020; Rosenthal et al., 2018) has supported the contention that replacing solid fuel cooking with cleaner fuel reduces GHG emissions. 

There is high agreement and robust evidence that switching cooking from unclean fuels and technologies to cleaner alternatives such as burning LPG or electric stoves offers health, air quality, and climate change benefits (Intergovernmental Panel on Climate Change [IPCC], 2022).

The IPCC (2022) identified unclean fuels such as biomass as a major source of short-lived climate pollutants (e.g., black carbon, organic carbon, carbon monoxide, and methane) and switching to cleaner fuels and technologies can reduce the emission of short-lived climate pollutants.

Regional and country-level analyses provide additional evidence of the efficacy of cleaner cooking solutions. Khavari et al. (2023) reported that in sub-Saharan Africa, replacing unclean solid fuels with cleaner cooking could reduce GHG emissions by 0.5 Gt CO₂‑eq/yr (100-yr basis). Life cycle assessments comparing different cooking fuels and technologies (Afrane & Ntiamoah, 2011; Afrane & Ntiamoah, 2012; Lansche & Müller, 2017; Singh et al., 2014) also have shown that cleaner cooking fuels and technologies emit less GHG per unit of energy delivered than unclean fuels.

The IEA estimated that switching completely to clean cooking fuels and technologies by 2030 would result in a net reduction of 1.5 Gt CO₂‑eq/yr (100-yr basis) by 2030 (IEA, 2023a). 

The results presented in this document summarize findings from five reviews and meta-analyses and 23 original studies and reports reflecting current evidence from 13 countries, primarily in sub-Saharan Africa. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.
