8. Sweden

Sweden is estimated to comprise about 9 million hectares of wetlands, the majority being mires. Since the beginning of the 1900s, wetland areas have been cultivated, mainly by draining the land for improved agricultural and forestry practices. To some extent, drainage has also occurred for infrastructure projects and the peat industry. Since the 1980s, wetlands have gained greater protection, along with increased knowledge and interest in restoring drained land. In the past five years, restoring wetlands has received growing political attention as it plays a key role in achieving national climate objectives.
Naturvårdsverket. (n.d.)
Total net greenhouse gas emissions from organic agricultural soils are estimated at 10.8 Mt CO₂e, representing one-fifth of Sweden's total greenhouse gas emissions.
Naturvårdsverket. (2023a)

Swedish climate targets and role of wetlands

  • By 2045, Sweden aims to achieve zero net greenhouse gas emissions, with net emissions becoming negative thereafter. These calculations cover only emissions within Sweden's borders and exclude sectors under the EU ETS. Agriculture, which is not part of the EU ETS, accounts for about one-fourth of Sweden's total emissions.
  • Restoring and rewetting peatlands are key measures for reducing greenhouse gas emissions. These measures are crucial as achieving net-zero emissions in the agricultural sector is expected to be challenging. In Sweden, peatlands are expected to play a vital role in enhancing carbon sinks and reducing CO₂ emissions.
    Sveriges Miljömål (2023)

8.1 National rewetting policies and objectives

Sweden does not have a national target specifying the amount of land to be rewetted or the types of land to prioritise within a set timeframe. However, the primary goal of wetland restoration and rewetting is to achieve climate mitigation, aligning with Sweden's national climate strategy and its overarching objective to become climate-neutral by 2045.
Regeringen (2024)
In an official national assessment Vägvalsutredningen carried out for the government in 2020,
Statens Offentliga Utredningar (2020)
rewetting was suggested as a socio-economically efficient policy measure to reach the climate neutrality goal in time. The assessment identified that 100.000 hectares of forest land and 10.000 hectares of agricultural land has potential for rewetting. Rewetting drained peatlands is highlighted as a priority area for maximising emission reductions. Since 2020, the report has guided government rewetting policy initiatives, with forestry land becoming a strategic focus. Funds have been earmarked for wetland construction costs and compensation to landowners. However, there is still no overarching national goal specifying how much land or which types of land should be rewetted within a set timeframe. The national policy documents for rewetting are listed in Table 13 below.

Priorities of the Swedish Government 2023 – Climate and Energy

The National Action Plan for Climate Adaptation (2023) highlights how wetland restoration supports climate adaptation and mitigation while promoting biodiversity and healthy ecosystems.
Regeringen (2024)
The action plan highlights that re-establishing wetlands is essential for developing infrastructure that is resilient to climate change. Rewetting is valued for its role in preventing flooding, mitigating water scarcity during dry periods through water storage, and reducing fire risks by improving water retention. Wetlands are recognised as important CO₂ storage areas, with rewetting crucial for reducing CO₂ emissions from organic peatlands.
Regeringen (2024)
Wetland restoration and rewetting are also mentioned in specific climate strategies for the county administrative boards (länsstyrelserna).

Regulation letter 2023 to the Swedish EPA

The 2023 regulation letter from the Swedish government to the Environmental Protection Agency (EPA) outlines its responsibilities regarding wetland rewetting, including specific tasks to be carried out:
  • Develop a document identifying geographical areas suitable for wetland rewetting, prioritising wetlands that contribute to climate change mitigation, biodiversity, water balancing, water quality, and groundwater. This should be done in collaboration with the Swedish Board of Agriculture and other relevant agencies.
  • Evaluate the need for a new support model for rewetting ditches on agricultural land to enhance carbon dioxide uptake and capture, working alongside the Swedish Board of Agriculture.
  • Guide on legal issues related to rewetting ditched peatland to ensure cost-effectiveness while respecting ownership and user rights. This should be done in collaboration with the Swedish Forest Agency and the Swedish Board of Agriculture.
    Statens Offentliga Utredningar (2022)
The government has assigned the responsibility for wetland restoration and re-establishment to several public agencies. The EPA serves as the primary coordinator, managing government funding and distributing it to the relevant agencies. The EPA also provides an overview of available funding opportunities on its website, which gives a clear overview of which stakeholders can apply, available funding schemes and public authority is responsible for the administration.
The Swedish Forest Agency focuses on rewetting privately owned forestry land, while the Agency for Marine and Water Management allocates funds to regions and municipalities for local rewetting initiatives on state-owned land. Additionally, the National Property Board and the Fortifications Agency are responsible for rewetting efforts on state-owned protected land, though their activities are on a much smaller scale compared to the other investments.
Regeringen (2024)
The Forest Agency handles and decides on financial support for forest landowners whereas the Swedish Agency for Marine and Water Management handles funding for rewetting to the regions, municipalities and local stakeholders. Rewetting initiatives from the Swedish Agency for Marine and Water Management are divided into climate adaptation initiatives and to improve sea or water environment quality (hydrological restoration).
Regeringen (2024)

Rewetting for hydrological and biological purposes

The Swedish term återvätning refers specifically to rewetting for climate purposes, while hydrological or biodiversity-focused efforts are described as wetland restoration or construction. Efforts focusing on natural hydrology and biodiversity have been ongoing since the early 2000s, but according to this study there are no national targets or references to them in government policy documents.
In Sweden, rewetting for nature restoration serves different purposes than återvätning for climate. Wetland restoration is primarily guided by Sweden's Environmental Quality Objectives, with Objective 11, "Thriving Wetlands" (Myllrande våtmarker), being central to these efforts.
Regeringen (2024)
Environmental Quality Objectives states that wetlands' ecological and water storage functions must be maintained, and valuable wetlands preserved for the future. Sub-objectives include the distribution and regeneration of wetland types, their conservation status, and their capacity to provide ecosystem services such as biological production, carbon storage, water management, purification, and regulation of water flows.
Naturvårdsverket. (2023c)
As part of the environmental quality objective, specific environmental quality standards for water bodies are outlined in line with the EU Water Framework Directive. The Swedish Water Authorities manage a regional action programme for 2022–2027, which includes wetland restoration to prevent drought and water scarcity.
Vattenmyndigheterna (n.d.)
Since Sweden joined the EU in 1995, the agricultural sector has undertaken rewetting initiatives, primarily to prevent and reduce eutrophication from agricultural land by limiting nitrogen and phosphorus runoff. These efforts focus on water quality rather than climate change mitigation and adaptation. Funding for rewetting on agricultural land comes exclusively from the European CAP, as farmers are not included in the national rewetting strategy for CO₂ reduction or the annual government funding for this purpose.
The 2020 government assessment identified a rewetting potential of approximately 10,000 hectares of agricultural land to reduce greenhouse gas emissions.
Statens Offentliga Utredningar (2020)
In 2023, the Swedish Environmental Protection Agency further evaluated the climate potential of rewetting across various scenarios and land types. This assessment serves as a key foundation for deciding whether the agricultural sector should be included in future government funding to enhance rewetting efforts on organic agricultural land, aligning with climate objectives.
Naturvårdsverket (2023a)

8.2 Economic instruments for rewetting initiatives

Funding to enhance CO₂ retention and reduce emissions, in line with Sweden's climate goals, is provided exclusively by the government, with no contributions from the EU. This support targets drained peatlands in forested areas, protected areas, and municipal land. It covers direct rewetting expenses and provides lump-sum compensation for forest landowners but excludes costs like wages. For 2024, the Swedish government has allocated €30.85 million for rewetting projects, with €20.42 million for 2025 and €32.58 million annually from 2026 to 2030.
Pourmokhtari, R. (2023).
The funding is partially allocated for compensation and installation costs, while the remainder supports personnel at agencies and municipalities involved in rewetting activities and disseminating information about the funding. Table 14 below outlines the funding schemes aiming at reducing greenhouse gasses through rewetting initiatives.

Compensation agreement for forestry landowners

In 2024, the Forest Agency received €6.95 million to compensate landowners for rewetting drained forestry peatlands.
Skogstyrelsen (n.d.-a)
The Forest Agency handles all preparations, planning, and implementation of wetland restoration. The programme involves a 50-year agreement between the Forest Agency and the landowner, primarily aimed at reducing greenhouse gas emissions. The agreement outlines how rewetting should be carried out on the designated land.
Compensation is based on the estimated economic loss from reduced tree growth, averaging 25% of normal forestry practices. Rewetting also affects the land’s bearing capacity, limiting clear-cutting activities. Landowners receive compensation equivalent to 35% of the land's estimated value, with higher payments for more fertile soils due to their greater potential for net greenhouse gas emission reductions. As a result, southern Sweden, with its more fertile soils, is prioritised for these cost-efficient initiatives.
To maximise climate benefits, rewetting should focus on well-drained, nutrient-rich peat soils in southern Sweden, particularly organic agricultural land. In contrast, rewetting nutrient-poor soils, especially in northern Sweden, can sometimes risk increasing net greenhouse gas emissions. (Naturvårdsverket 2023c).
Landowners do not receive compensation for timber on the land, as the agreement allows them to retain ownership and the right to fell timber throughout the contract period. The maximum compensation per hectare of land is currently €2,780.
Skogstyrelsen (n.d.-a)

LONA Wetlands

The Agency for Marine and Water Management distributes funds to Swedish regions (länsstyrelserna), which are responsible for local rewetting projects through the LONA-wetlands funding scheme (Lokala naturvårdssatsningen). Only municipalities can apply for this funding, with grants covering up to 90% of eligible costs. In 2024, €8.08 million was allocated to the regions for these initiatives.
Havs och Vatten myndigheten (2020)

Action Programme for Protected Areas

The EPA is responsible for wetland restoration within protected areas, including nature reserves and national parks, as part of the Action Programme for Protected Areas. These areas contain habitats of exceptionally high natural value. In 2024, the EPA received €11.3 million to fund hydrological restoration efforts, with a primary focus on peat-rich bogs spanning extensive areas.
Naturvårdsverket (2023c)

Funding schemes for rewetting with hydrological and biological objectives

As outlined in national policies, there is also funding available with a broader focus on wetland restoration, which includes rewetting but has more focus on the restoration of pristine landscapes and therefore not focus on climate change mitigation. This funding targets other types of land, with the primary objectives of improving hydrological conditions, enhancing biodiversity, or reducing eutrophication. It is financed through a combination of government funding, private contributions from NGOs, and EU programmes such as LIFE and the CAP.
The Swedish Board of Agriculture allocates funds from the CAP to farmers for the re-establishment and restoration of wetlands. The primary aim of these investments is to reduce the transport of nitrogen and phosphorus from agricultural land into lakes, seas, and other water habitats. Farmers in Sweden have been receiving EU funding under the CAP programme since the country joined the European Union in 1995.
Jordbruksverket (n.d.)
In 2023, for the first time, funds were allocated to the National Property Board (€0.35 million) and the Swedish Fortifications Agency (€0.09 million) to implement rewetting initiatives on state-owned land.
Naturvårdsverket (2023c)
The objectives are to strengthen biodiversity and ecosystem services, reduce greenhouse gas emissions, decrease eutrophication, and improve groundwater infiltration.  
Swedish regions are responsible for funding schemes for local rewetting projects, through LOVA
Länsstyrelsen Skåne (n.d.)
(Lokala vattenvårdsprojekt) and LONA. Municipalities and local CSOs can apply for funding for restoration and construction of wetlands. Projects include closing ditches, restoring water habitats and swamp forests, and preparatory work for wetland restoration or construction. Under LOVA (specifically for wetlands), 80% of eligible costs are covered.
Naturvårdsverket (2023b)
However, neither LONA nor LOVA can compensate landowners for any lost economic profit on the converted land.
Naturvårdsverket (2023c)
The Swedish Society for Nature Conservation provides a 10% top-up on the 90% funding from LONA-wetlands. This allows landowners to receive grants covering 100% of construction costs for rewetting and restoration projects.
Naturskyddsforeningen (2023)
Municipalities, companies, CSOs, and public agencies can apply for rewetting funding through EU-LIFE, financed directly by the EU Commission. The programme primarily aims to restore and protect biodiversity. LIFE co-financing covers up to 60%, depending on the applicant type, and supports rewetting on both agricultural and forest land. The Swedish EPA provides guidance during the application process.
Naturvårdsverket (2023c)

Conflicts with other national objectives

In an interview with Swedish EPA, the multifunctional purposes of wetlands were raised with uncertainty, as rewetting is highly prioritised for climate change mitigation efforts in Sweden.
EPA, personal communication, November 11, 2024
In the interview it was expressed that rewetting initiatives on different land types have varying effects on the environment and carbon sequestration. Prioritising only the most climate-efficient outcomes, such as peatlands with high organic matter content, risks underprioritizing other wetlands, like nutrient-poor soils in the north, which support unique biodiversity. This could potentially negatively impact red-listed species and habitats. The EPA emphasises the importance of considering both climate and environmental perspectives when prioritising rewetting initiatives to ensure a balanced mix of outcomes.
Nutrient-rich peatlands, mainly in southern Sweden, are used for agriculture, while nutrient-poor peatlands in the north (mineral soils) support unique biodiversity and are used for forestry. According to the EPA, compensating farmers for rewetting agricultural land is more costly because the land is valuable for food production and has higher nutrient content due to cultivation. Before rewetting, nutrients may need to be removed to prevent eutrophication in nearby land and water bodies.
Stockholms universitets Östersjöcentrum (2024). Multifunctional wetlands – reality or utopia?
While rewetting in most cases are beneficial for both climate and the environment, the EPA highlights a risk of the government focusing too narrowly on uniform rewetting for climate purposes.
Rewetting forestry land can conflict with timber production, a key industry for Sweden and a major export sector, as it significantly slows tree growth on drained peatlands. However, according to the Forest Agency, this has not yet been a major issue (as of November 2024) since rewetting efforts have primarily targeted non-productive forestry land.
Skogsstyrelsen, personal communication, November 7, 2024
To accelerate CO₂ emission reductions, richer peatlands may increasingly be targeted for rewetting, potentially conflicting with timber production. A researcher from Stockholm University, part of the sounding board, highlighted this issue, noting the lack of political focus on forest restoration and protection. Instead, priority is given to the economic importance of the forest industry as a key export sector, which negatively impacts investments and prioritisation of rewetting forestry-drained peatlands.

8.3 Rewetting policy evaluations and monitoring

Rewetting for climate purposes in Sweden has only been a political priority since the early 2020s, so evaluations and monitoring of these policies remain limited. However, a few notable surveys and evaluations, as presented in the following sections, have been conducted, with some ongoing efforts assessing rewetting policies on both agricultural and forestry land.

Peat-map to guide rewetting initiatives

In December 2023, the Swedish EPA, in collaboration with the Board of Agriculture and the Forest Agency, completed a mapping of the most suitable geographical areas for rewetting on drained peatlands. The Forest Agency manages the “peat-map,” which helps landowners determine if their land is suitable for rewetting.
Skogstyrelsen (n.d.-b)

Compensation agreement forestry landowners

A 2024 survey by the Swedish EPA explores forest landowners' attitudes toward rewetting since financial compensation and agreements were introduced in 2020. The key finding for the survey is that landowners primarily are motivated by environmental benefits, such as improved biodiversity and ecosystems, rather than the climate impact of rewetting. This is likely because biodiversity and ecosystem effects are more tangible and visible, while climate benefits are more abstract. This insight will likely influence communication and advisory efforts, particularly by the Forest Agency and the Board of Agriculture, when engaging with landowners about rewetting.
Naturvårdsverket (2024)
A recent evaluation of compensation agreements for forest landowners examines the main drivers and barriers for committing to rewetting agreements. The study also found that biodiversity benefits are the primary incentive, while climate effects are seen as secondary. Economic compensation was considered less important, though forest owners noted that higher compensation could encourage more participation, as current levels do not fully cover their costs. A notable barrier is the historical perception of rewetting, as older generations worked hard to drain the land, and some landowners view rewetting as undoing that effort. Additionally, many landowners feel there is a lack of knowledge about rewetting and its long-term impact on their land. While those who had direct contact with the Forest Agency reported positive dialogues, uncertainties remain regarding the economic and ecological effects over time. This report is part of a larger assessment of rewetting agreements, which will be completed and available in early 2025.
Isaksson et al. (2024)
Additional insights on the experiences from current rewetting agreements were shared by a Forest Agency policy expert during an interview for this study.
Forest Agency, personal communication, November 3, 2024
Since rewetting became a priority in Sweden's climate strategy, the government expects rapid reductions in CO₂ emissions. However, many landowners remain unaware of rewetting, its effects, eligibility for compensation, and what the agreements cover, leading to a slow start. The Forest Agency representative highlighted the need for extensive efforts to inform landowners about available compensation and educate them on the benefits for climate and biodiversity. To accelerate rewetting agreements, the agency emphasises the need for greater awareness among landowners and additional resources to engage directly with landowners.
The Forest Agency states that the compensation value for landowners has not yet been evaluated. Assessing whether it is appropriately priced or if adjustments in compensation levels could improve efficiency would be useful. The Agency states that further analysis is needed to determine if the current level is optimal from a socio-economic perspective. According to the EPA survey on landowners' attitudes toward rewetting, the current compensation level does not appear to be the primary motivator for rewetting. Instead, the positive effects on biodiversity and ecosystems are the main drivers. However, it is still mentioned by the landowners that higher compensation could potentially incentivise landowners less focused on environmental benefits to engage in rewetting. Nevertheless, there is not enough understanding today of to what extent the compensation level aligns with landowners' perceptions of their land's value when rewetted.

Legal barriers to rewetting initiatives

In 2024, the government tasked the Swedish EPA, in collaboration with the Swedish Agency for Marine and Water Management and the Swedish Board of Agriculture, to review legislation that may hinder rewetting initiatives. The agencies will assess the need for changes to soil drainage regulations to facilitate wetland restoration where no conflicting interests, such as productive agricultural or forestry land, exist. The investigation will analyse laws related to land and property ownership, identifying obstacles such as outdated drainage regulations and overly complex contracts. Many contracts are so old that finding the original landowners is difficult, and larger rewetting projects often involve multiple landowners. To make rewetting initiatives more efficient and ensure their intended climate benefits, regulations for water operations and land drainage must be updated. The results from the investigation will be finalised in 2025.
Regeringen (2024)

Basis for rewetting wetlands – analysis from the EPA to the government

In a report to the government published by the Swedish EPA in 2023, rewetting and its climate potential are evaluated in relation to the support mechanisms implemented.
Naturvårdsverket. (2023c)
The rewetting potential of 100,000 hectares of forest land and 10,000 hectares of agricultural land, identified in the 2020 government assessment, was re-evaluated in light of the new available funding. The 2020 report's suggestions remain valid as effective measures to support the goal of climate neutrality by 2045. However, the report highlights that counselling efforts are crucial for achieving rewetting objectives on time. Improved local support and direct dialogue with landowners are essential to raise awareness of support mechanisms and enhance knowledge about rewetting and its effects. The EPA recommends prioritising these efforts to accelerate progress. This conclusion is echoed by the Forest Agency, which notes that insufficient resources have been allocated to these activities, despite their importance in speeding up rewetting.
Skogsstyrelsen, personal communication, November 7, 2024
It is furthermore recommended by the Swedish Board of Agriculture to implement previously suggested measures to restore 10,000 hectares of agricultural land into wetlands, as this is the most effective method for significantly reducing CO₂ emissions from agricultural land.
Markensten et al. (2018)
Consequently, the compensation scheme should be adapted to also include drained agricultural land.
Naturvårdsverket (2023c)
Emission reduction calculations show a decrease of 1 to 9 tonnes of CO₂e per hectare per year for forest land and approximately 21 tonnes per hectare per year for agricultural land on organic peatlands. These figures represent net reductions, factoring in the initial rise in methane emissions after rewetting, which diminishes over time.
Statens Offentliga Utredningar (2020)

Reporting on area and emissions reductions from rewetting initiatives

The Swedish University of Agricultural Sciences has analysed the effects of rewetting activities under several national programmes, including LONA (LONA wetlands), LOVA, The Forest Agency´s compensation agreement to forestry landowners, the Rural Development Program, the Action program for protected species, the Action program for valuable nature, and other forms of funding support. The report was commissioned by the Swedish EPA and published in 2024.
Lundblad (2023)
It states that in 2023, 2,100 hectares of drained wetlands were rewetted through the government budget initiative, including 1,500 hectares of peatlands, covering a total of 588 projects. These efforts were estimated to have reduced emissions by 6.1 kt CO₂eq. Table 15 shows an overview of the total rewetted area supported by the national programs in the years 2021-2023.

The climate effects of rewetting are not yet included in Sweden's official climate reporting (CRF tables). This is mainly due to the IPCC's unreliable guidance, based on limited studies, and the lack of sufficient data from various programmes. However, the report’s findings will be included in Sweden's next annual climate report to the IPCC.
Lundblad (2023)

8.4 Concluding remarks

The main objective of Swedish rewetting (“återvätning”) policies is climate change mitigation. However, there are no clear political targets for rewetting or wetland restoration, including specific areas to be rewetted or expected emission reductions. While studies by the EPA, the Forest Agency, and the Board of Agriculture have estimated the hectares required to meet climate goals, as well as the types of land and incentives needed, these suggestions have not been formalised into policy. The absence of clear targets makes it difficult for agencies to prioritise initiatives. Currently, only forestry land receives government funding for rewetting, while agricultural land is supported through the CAP plan, focusing on eutrophication rather than GHG mitigation. The EPA has suggested expanding Forest Agency rewetting agreements to include agricultural land to ensure long-term protection and offer financial incentives for farmers. Despite the vague policy landscape, the centralised responsibility delegated to the EPA provides a clear and accessible overview of Sweden’s rewetting policies.
