Boreal peatland restoration

Peatland restoration is the process of returning peat-forming vegetation and natural hydrologic conditions to degraded peatlands. Restoration of peatlands stops GHG emissions from peat degradation and removes carbon through sequestration in biomass and peat.

This solution focuses on non-coastal peatlands that have been drained, cleared of vegetation, harvested for peat, or otherwise degraded. Coastal peatlands are addressed in the Restore Mangrove Ecosystems and Restore Salt Marsh Ecosystems solutions.

Overview

Peatlands are diverse ecosystems characterized by waterlogged, carbon-rich soils consisting of partially decomposed dead plant material (Figure 1). Because decomposition occurs very slowly under low oxygen, waterlogged conditions, large amounts of partially decomposed plant material accumulated over millennia in peatlands. These carbon-rich ecosystems occupy only 3–4% of land area (Xu et al., 2018; United Nations Environment Programme [UNEP], 2022), but store an estimated 600 Gt carbon (~2,200 Gt CO₂‑eq), roughly twice as much carbon as is stored in forest biomass globally (UNEP, 2022; Yu et al., 2010; Pan et al., 2024). Approximately 12% of global peatlands (~57 Mha) have been drained or otherwise degraded for agriculture, forestry, peat extraction, or other uses. Restoration of degraded peatlands through revegetation and rewetting (returning to a waterlogged state; Evans et al., 2021) reduces ongoing emissions and can restore the ability of the ecosystem to sequester carbon.

Figure 1. These photos show the diversity of peatlands that occur in different places, including a fen peatland and meadow complex in California (top left), a peat swamp in Indonesia (top right), a peat fen and forest in Canada (bottom left), and a peat bog in New Hampshire (bottom right).

Draining and/or clearing peatlands increases CO₂ emissions, nitrous oxide emissions, and losses of dissolved carbon through waterways while also reducing carbon sequestration and methane emissions. CO₂ from peat decomposition is the largest source of GHG emissions from degraded peatlands (Intergovernmental Panel on Climate Change [IPCC] Task Force on National Greenhouse Gas Inventories, 2014; UNEP, 2022). When accumulated organic matter in the peat layer is exposed to air, it begins decomposing more rapidly, emitting CO₂ (Figure 2). Removal of overlying vegetation produces additional GHG emissions while also slowing or stopping carbon uptake and continued peat formation. Whereas emissions from vegetation removal occur rapidly following disturbance, peat decomposition and associated emissions can continue for centuries depending on environmental conditions and peat thickness (Leifield & Menichetti, 2018). Peatland restoration halts these emissions and, eventually, can restore the ecosystem's ability to take up carbon (Doelman et al., 2023; Humpenöder et al., 2020; Mander et al., 2024; Mander et al., 2025; Strack et al., 2022). 

Peatland disturbance and restoration also have complex impacts on nitrous oxide emissions, methane emissions, and carbon loss through waterways (Figure 2; IPCC Task Force on National Greenhouse Gas Inventories, 2014; UNEP, 2022). Intact peatlands are a methane source because methane-producing microbes thrive under waterlogged conditions, so restoring peatlands typically increases methane emissions (Evans et al., 2021; Günther et al., 2020; Huang et al., 2021; Mander et al., 2024). However, restoration typically reduces nitrous oxide emissions from oxidation of the peat layer. 

Figure 2. Intact peatlands (left) are a net greenhouse gas sink, sequestering carbon in peat through photosynthesis but also emitting methane due to waterlogged soils. Drained peatlands (right) are a GHG source, producing emissions from peat decomposition and drainage canals.

Peatlands can be restored to native vegetation or used for paludiculture, the practice of growing crops or trees in saturated conditions (Tan et al., 2021; Temmink et al., 2026). We assume that effective restoration involves both rewetting and re-establishment of perennial vegetation, and in this assessment we did not differentiate between carbon dynamics on peatlands restored to native vegetation and those on peatlands used for paludiculture. Because peatland emissions dynamics, total peatland areas, and the degraded peatland area all vary geographically, we evaluated tropical, subtropical, temperate, and boreal regions separately in this analysis. Most peatlands occur in boreal regions (~310 Mha, or 64% of the total), with another 25% (~121 Mha) in tropical regions (UNEP, 2022; Protect Peatlands). These regions also contain the largest areas of degraded peatlands that can be restored (26 Mha and 19 Mha, respectively; UNEP, 2022).

Halting the ongoing drainage and degradation of peatlands through effective protection, which is covered in Protect Peatlands, is an essential complement to restoration (Austin et al., 2025).

The Details

Current State

Using the IPCC’s Tier 1 methodology (IPCC Task Force on National Greenhouse Gas Inventories, 2014), we estimated the net effectiveness of peatland restoration at 19.0–56.0 t CO₂‑eq /ha/yr (100-yr basis), depending on the climate zone (Table 1a–d). 

The primary pathway by which peatland restoration reduces emissions is by slowing or stopping CO₂ emissions associated with loss of peat through oxidation. Because peat oxidation occurs more rapidly in warmer climates, the effectiveness of restoration is higher in tropical and subtropical regions than in temperate and boreal regions (IPCC Task Force on National Greenhouse Gas Inventories, 2014). We estimated that drained peatlands emit 15.1–49.7 t CO₂‑eq /ha/yr, while restored peatlands can range from carbon sinks (–1.6 t CO₂‑eq /ha/yr on average in the boreal) to small sources (0.5 t CO₂‑eq /ha/yr on average in temperate areas). However, site-level variability is high, with a recent review reporting values ranging from a sink of –42 t CO₂‑eq /ha/yr (in a restored Canadian sphagnum bog) to a source of 8 t CO₂‑eq /ha/yr (at a restored German sphagnum paludiculture site) (Mander et al., 2024; Oestmann et al., 2022; Strack et al., 2014).

Peatland restoration influences GHG emissions from several other pathways as well:

  • Revegetation can increase carbon sequestration in biomass. Here, we included carbon uptake in vegetation only for degraded peatlands that were originally forested (Olson et al., 2001) and are currently used for agriculture (UNEP, 2022), using reforestation carbon uptake rates from Robinson et al. (2025) and Busch et al. (2024) (see Restore Forests). Carbon uptake from reforestation on peatlands contributes 3.2–8.3 t CO₂‑eq /ha/yr (100-yr basis) on average within each climate zone, with larger emissions benefits in warmer climates. 
  • Nitrous oxide emissions associated with peat oxidation are reduced (IPCC Task Force on National Greenhouse Gas Inventories, 2014). 
  • Off-site CO₂ emissions from losses of dissolved organic carbon through drainage canals and surface waterways are reduced (IPCC Task Force on National Greenhouse Gas Inventories, 2014). 
  • Methane emissions arising from drainage canals are eliminated when canals are filled (IPCC Task Force on National Greenhouse Gas Inventories, 2014). However, methane emissions from canals can persist if they are simply blocked or partially filled (Peacock et al., 2021). These emissions remain uncertain, and our effectiveness estimates rely on the optimistic assumption that canals are fully filled, eliminating canal methane emissions.
  • Methane emissions from the peat itself typically increase as the peat returns to an anoxic state. Methane emissions from the surface of restored peatlands are estimated at 1.5–5.7 t CO₂‑eq /ha/yr (100-yr basis), compared to 0.1–0.2 t CO₂‑eq /ha/yr (100-yr basis) for drained peatlands (IPCC Task Force on National Greenhouse Gas Inventories, 2014). This increase in methane emissions is included in the effectiveness estimates. 
  • Restoring peatlands currently used for crop production can displace that production and expansion of agricultural land use elsewhere, producing emissions from land use change (Burney et al., 2010; Lobell & Villoria, 2023). We used a very simple approach to estimate emissions from this indirect land use change, assuming that the production lost from peatland restoration is replaced on non-peat ecosystems within the same climate zone at the average yield (see Methodology for additional details). These indirect land use change emissions, ranging from 1.7–4.9 t CO₂‑eq /ha/yr across ecosystems, slightly reduce the effectiveness of restoring peatlands.

The costs of peatland restoration are highly uncertain and variable. We estimated that the median cost of peatland restoration is approximately US$55/t CO₂‑eq (2023 US$), or US$1,884/ha restored (Table 2). These estimates are based on data from only three countries. In Scotland, peatland restoration costs are submitted as part of the Peatland Action Programme, which provides grants for peat restoration (Glenk et al., 2022). Based on data from 300 sites, they report a median cost of US$1,884/ha (equal to US$55/t CO₂‑eq , 100-year basis). In the United States, the U.S. Department of Agriculture developed models of restoration costs based on contracts with agricultural landowners for wetland restoration through the Wetlands Reserve Program, with costs ranging from US$170/ha to US$6,100/ha depending on the region. All other cost data used in our calculations are from Indonesia, with estimates ranging from US$237/ha to more than US$25,000/ha (Hansson & Dargusch 2018; Tan et al., 2022). Peatland restoration costs include the costs of restoring the natural hydrologic condition and of revegetation, and depend largely on the size of canals that must be dammed or filled (Hansson & Dargusch 2018). These estimates do not include forgone revenues from economic uses of drained peatlands, nor do they include potential new revenues from paludiculture, tourism, or ecosystem service payments.

Median 55

We define a learning curve as falling costs with increased adoption. There is no evidence that the costs of peatland rewetting and revegetation will fall with increasing adoption. Therefore, there is no learning curve for this solution.

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. Restore Peatlands is a GRADUAL climate solution, because the primary mode of action is a reduction in emissions that would otherwise occur on an annual basis over a long time. It has a steady, linear impact on the atmosphere. 

Adoption

Data on the current adoption of peatland restoration are very sparse, noncentralized, and largely not validated. Therefore, we do not provide a global estimate of the currently restored area. We found two countries for which there are national-scale estimates of restored area. The United Kingdom’s Peatland Programme reports that restoration activities were undertaken on 254,254 ha of peatland between the 1990s and 2024 (IUCN UK Peatland Programme, 2024). In Indonesia, the Ministry of Environment and Forestry reported 3.7 Mha of peatland restoration in a 2022 report based on estimates of the area with a water table depth of 40 cm or less as of December, 2021. However, only 6,000 of these ha were reported to have undergone some form of vegetation restoration, and water table depth is a limited proxy for peatland restoration status because it fluctuates substantially over time due to natural variability in water supplies. For instance, the area meeting the water table threshold had fallen to just 0.5 Mha by June 2022 (Jong, 2023; The Gecko Project, 2022). Based on published estimates, it seems likely that the peatland area that has been successfully restored is in the range of 0.5–5Mha.

Peatland restoration data are very limited and rarely temporally resolved. The available data are insufficient to calculate an adoption trend for this solution.

We estimated the adoption ceiling for peatland restoration to be 56.9 Mha (Table 3). This is the area of peatland that has been drained or converted to other land uses (UNEP, 2022) and represents ~12% of the total global peatland area. Approximately 37.8 Mha of drained peatlands are currently used for agriculture (croplands or grazing), 18.1 Mha are used for forestry, and 1.0 Mha are used for peat extraction (UNEP, 2022). Although restoring peatlands will involve displacing some of these activities to other lands. Though drained peatlands can be particularly high-yielding (Lloyd et al., 2023), these are relatively small areas in the context of global land use. For example, agricultural peatlands (including both croplands and grazing lands) represent less than 3% of total global croplands, which were estimated to cover ~1,500 Mha circa 2020 (Tubiello et al., 2023). Indirect land use change emissions arising from relocation of croplands are accounted for in our effectiveness estimates.

Drained peatlands are concentrated in boreal (26.3 Mha) and tropical regions (18.5 Mha), with smaller areas in temperate (9.9 Mha) and subtropical (2.1 Mha) regions (UNEP, 2022). The proportion of peatlands that have been drained is largest in temperate regions (28%), followed by the tropics (15%), subtropics (14%), and then the boreal (8%).

These values reflect best estimates of drained peatland area from the Global Peatland Assessment (UNEP, 2022). However, there is substantial uncertainty in the distribution of intact and drained peatlands, and efforts to map global peatlands are ongoing (Melton et al., 2022; Minasny et al., 2024).

Estimate 56,900,000

We assumed an achievable range of 25–50% of the adoption ceiling, equal to 14.2 – 28.4 Mha of peatland restoration (Table 4a–e). 

The momentum behind peatland restoration has been growing rapidly over the past several decades, including major international efforts such as the U.N. Decade on Ecosystem Restoration (2021–2030), the Global Peatlands Initiative, and the Peatland Breakthrough (Global Peatlands Initiative, 2025; UNEP, 2022; Wetlands International, 2025). Our estimate of the high achievable level of peatland restoration roughly aligns with the 30 Mha target of the Peatland Breakthrough, a global initiative to guide peatland restoration through unified targets and restoration principles that was launched at COP30 (Global Peatlands Initiative, 2025). Given that the current area successfully restored is likely in the range of 0.5–5 Mha, both the low and high achievable estimates will require an ambitious expansion of peatland restoration. 

Peatland restoration will very likely need to be directly incentivized through payments for ecosystem services such as emissions reductions, water quality, flood management, and/or biodiversity to achieve this level of adoption (Bonn et al., 2014). Paludiculture, or using restored peatlands for production of commodities that tolerate saturated conditions, may also boost restoration (Mander et al., 2024; Tan et al., 2021; Ziegler et al., 2021). In temperate and lower boreal regions, paludiculture is typically characterized by herbaceous vegetation, including cattails, reeds, canary grass, sedges, and alder, used for grazing or biomass and by cultivation of sphagnum for horticultural use (Temmink et al., 2026). Additional research is needed to develop suitable paludiculture systems for restored tropical peatlands (Uda et al., 2020), which are typically characterized by tree cover rather than herbaceous plants. Sustainable gathering and hunting of native peatland species is a form of paludiculture that has been practiced by indigenous communities for centuries, and tree crops such as sago and jelutong show some potential for economically viable paludiculture (Tan et al., 2021; Ziegler et al, 2021).

Impacts

We estimated that peatland restoration could reduce emissions by 0.48 Gt CO₂‑eq/yr at the low-achievable adoption scenario, 0.97 Gt CO₂‑eq/yr at the high-achievable adoption scenario, and 1.93 Gt CO₂‑eq/yr at the adoption ceiling (Table 5a–e). Our estimate of the climate impact at the adoption ceiling is approximately in line with literature estimates of annual emissions from drained peatlands (e.g., 1.98 Gt CO₂‑eq/yr from Leifield and Menichetti [2018]). 

Although the total area available for restoration is largest in the boreal biome, more than half of the adoption ceiling climate impact occurs in the tropics due to larger per-hectare emissions reductions from peatland restoration in warmer climates. Restoration in boreal regions is estimated to provide 26% of the climate impact at the adoption ceiling, with an additional 15% and 5% of the climate impact available through temperate and subtropical peatland restoration, respectively.

Extreme Weather Events

Peatland restoration can help communities adapt to extreme weather, though restored peatlands may be more sensitive than undisturbed peatlands to extreme weather (Loisel & Gallego-Sala, 2022). Because peatlands regulate water flows, they can reduce the risk of droughts and floods (IUCN, 2021; Ritson et al., 2016). Evidence suggests that peatlands can cool the immediate environment, lowering daytime temperatures and reducing daily temperature extremes (Dietrich & Behrendt, 2022; Helbig et al., 2020; Worrall et al., 2022).

Income and Work

Peatlands support the livelihoods of nearby communities, especially those in low- and middle-income countries. In the peatlands of the Amazon and Congo basins, fishing livelihoods depend on aquatic wildlife (Thornton et al., 2020). Peatlands in the Peruvian Amazon provide important goods for trade, such as palm fruit and timber and are used for hunting (Schulz et al., 2019). Peatlands can also support the livelihoods of women, allowing them to access more economic opportunities and contributing to gender equality. For example, in Indonesia women use raw materials from peatlands to create mats sold for use in significant events such as births, weddings, and burials (Goib et al., 2018). Selling commodities made from peatland materials increases household income and can increase the position of women to make decisions in a household (Goib et al., 2018).   

Restoring peatlands may come with some trade-offs to livelihoods if it prevents other productive uses. Paludiculture may help local communities to maintain their livelihoods on restored peatlands (Temmink et al., 2026; Yuwati & Pratiwi, 2022). Case studies in Southeast Asia have found that community-led restoration projects that consider local context and livelihoods are more successful than conventional restoration projects (Terzano et al., 2022).

Peatlands mitigate exposure to air pollution and can save money from reduced health-care expenditures (Kiely et al., 2021).

Health

When peatlands are drained, they are susceptible to fire, and rewetting reduces fire risk (Salmayenti et al., 2026). Peatland fires can contribute to air pollution because of the way these fires smolder (Uda et al., 2019). Smoke and pollutants, particularly PM2.5, from peatland fires can harm respiratory health and lead to premature mortality (Marlier et al., 2019). A study in Indonesia estimated peatland fires contribute to the premature mortality of about 33,100 adults and about 2,900 infants annually (Hein et al., 2022). Researchers have linked exposure to PM2.5 from peatland fires to increased hospitalizations, asthma, and lost workdays (Hein et al., 2022). 

Nature Protection

Peatlands support diverse flora and wildlife (UNEP, 2022; Minayeva et al., 2017; Posa et al., 2011), including many rare and threatened species (Posa et al., 2011). A study of Indonesian peat swamps found that the IUCN Red List classified approximately 45% of mammals and 33% of birds living in these ecosystems as threatened, vulnerable, or endangered (Posa et al., 2011). Peatlands also support a variety of insect species (Spitzer & Danks, 2006). Because of their sensitivity to environmental changes, some peatland insects can act as indicators of peatland health and play a role in conservation (Spitzer & Danks, 2006).

While restored peatlands are more biodiverse than degraded ecosystems, restored peatlands are often less biodiverse than intact peatlands (Renou-Wilson et al., 2019). For example, a large study of peatlands in Europe found that rewetting increased biodiversity of peatlands, but plant composition was different from natural, intact peatlands (Kreyling et al., 2021). Biodiversity benefits have also been identified in European paludiculture systems, though more research on the biodiversity impacts of paludiculture is needed (Martens et al., 2023).

Water Resources

Peatlands can filter water pollutants and improve water quality and are important sources of potable water (Minayeva et al., 2017). Xu et al. (2018a) estimated that peatlands store about 10% of freshwater globally, not including glacial water. Peatlands provide potable water for about 71.4 million people, primarily in the United Kingdom and Ireland (Xu et al., 2018a). 

Water Quality

For a description of water quality benefits, please refer to the “water resources” subsection above. 

Other

GHG emissions dynamics of rewetted peatlands remain uncertain because they can be highly variable depending on site level factors, such as land use history, type of restoration interventions, and environmental conditions (Mander et al., 2024). 

Effective peatland restoration faces many barriers, including cost of restoration, disruption to economic use, willingness of local community and landowners to support restoration, and technical challenges, particularly on severely subsided sites (Andersen et al., 2017; Harrison et al., 2020; Lestari et al., 2024; Zeng et al., 2020).

Peatland restoration, like other nature-based climate solutions, faces concerns related to the permanence of emissions reductions and carbon sequestration (Loisel & Gallego-Sala, 2022; Turetsky et al., 2015). Restored peatlands are vulnerable to drainage or clearing, which can be mitigated by coupling restoration with long-term protections. Restored peatlands are also vulnerable to natural disturbances, such as fires and droughts, though they tend to be more resilient than drained peatlands (Granath et al., 2016). 

Where peatland restoration involves removing agricultural or forestry land from economic use, it risks compromising the livelihoods of local communities (Lestari et al., 2024; Merten et al., 2021; Ward et al., 2020). Close collaboration with local communities can facilitate procedural equity and enable positive, durable outcomes for both the ecosystem and the community (e.g., Toumbourou et al., 2024). Additionally, restoring peatlands can trigger displacement of production activities onto other lands, resulting in land clearing elsewhere (i.e., leakage). We account for the emissions impacts of leakage in our effectiveness calculations. While restoration can reduce emissions associated with agriculture locally, these emissions can occur elsewhere if the production area shifts. Paludiculture can reduce the risk of negative economic impacts and leakage (Mander et al., 2024; Tan et al., 2021; Ziegler et al., 2021). 

Though healthy peatlands provide water quality benefits, peatland rewetting can mobilize nutrients and other contaminants into surface waters (Breznikar et al., 2024; Heuts et al., 2026; Silverthorn et al., 2026; van der Laan). Studies have found increases in phosphorus, nitrogen, and heavy metal loads from peatland rewetting, though effects are mixed. Water quality monitoring and appropriate mitigation near restoration sites can help manage water quality risks (e.g. Hoffman et al., 2026).

Peatland restoration can divert resources from other climate solutions, including protecting intact peatlands. Preventing peatland drainage is typically more cost effective and offers larger emissions benefits than does peatland restoration (see Protect Peatlands). Restoration should therefore complement, rather than compete with, efforts to reduce further disturbance of intact peatlands.

Peatland restoration can improve the health and function of adjacent ecosystems that are being protected or restored.

Competing

These solutions are all suitable to implement on degraded peatland, and thus are in competition with restoration.

Consensus of effectiveness in reducing emissions from disturbed peatlands: High 

Consensus of effectiveness in providing substantial net GHG removal in the near future after accounting for increases in methane emissions: Low

Degraded peatlands currently emit an estimated 1.3–1.9 Gt CO₂ ‑eq/yr (excluding fires), equal to ~2–4% of total global GHG emissions (Leifield and Menichetti, 2018; UNEP, 2022). Leifeld et al. (2019) projected that without protection or restoration, drained peatlands could produce enough emissions to consume 12–41% of the remaining emissions budget for keeping warming below 1.5–2.0 °C. Peatland drainage had produced a cumulative 80 Gt CO₂ ‑eq by 2015, equal to nearly 16 months’ worth of total global emissions (60.3 Gt CO₂‑eq/yr as of 2024). 

Peatland rewetting and restoration has been widely shown to stop ongoing CO₂ emissions from oxidation of drained peat and reduce lateral transport of carbon through waterways (Günther et al., 2020; Mander et al., 2024; Wilson et al., 2016). The net emissions reduction in rewetted relative to drained conditions is clear and consistent, despite large variability in the magnitude of carbon uptake and methane and nitrous oxide emissions following rewetting. While many restored peatlands regain their capacity to act as net carbon sinks, some sites remain emissions sources for decades following rewetting (Strack & Zuback 2013; Vanselow-Algan et al., 2015; Wilson et al., 2016).

 The results presented in this document summarize findings from 19 reviews, meta-analyses, and global databases reflecting current evidence for peatland restoration. The majority of the non-global literature is focused on Indonesia, the United Kingdom, and Northern Europe. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.
