GENERAL INFORMATION ON CARBON SEQUESTRATION AND EMISSION OFFSETTING
What is carbon sequestration?
Carbon sequestration is the process of removing carbon dioxide (CO2) from the atmosphere and storing it in natural or technological reservoirs. Biological carbon sequestration occurs through natural systems like forests and plants, while technological carbon sequestration involves techniques such as carbon capture and storage.
How does carbon sequestration affect climate change mitigation?
Carbon sequestration is a key method for mitigating climate change because it reduces the concentration of carbon dioxide, a major greenhouse gas, in the atmosphere. By lowering CO2 levels, carbon sequestration helps to slow down global warming, which in turn reduces extreme weather events, sea level rise, and disruptions to ecosystems. This process is essential for achieving international climate goals and ensuring a sustainable future.

Myths and facts about carbon sequestration
Myths:
1. Carbon sequestration replaces emissions reduction: In reality, carbon sequestration is an important complementary method for reducing emissions but is not sufficient on its own to mitigate climate change. Emissions reduction efforts are still crucial.
2. All forests are equally effective at carbon sequestration: The effectiveness of forests in carbon sequestration depends on their age, growth conditions, and management. Older forests may be less efficient carbon sinks compared to younger and actively managed forests.
3. Technological carbon sequestration solves all problems: Technological carbon sequestration, such as carbon capture and storage (CCS), is promising but still developing, facing challenges in scalability and cost.
Facts:
1. Biological carbon sequestration is a natural process: Plants, forests, and oceans are effective carbon sinks that naturally absorb carbon dioxide.
2. Reforestation and forest management enhance carbon sequestration: Well-planned reforestation and active forest management can significantly increase forests' capacity to sequester carbon and improve ecosystem health.
3. Carbon sequestration is part of the overall climate solution: It needs to be combined with emissions reduction across all sectors, including energy production, industry, and transportation.
Understanding both the myths and facts about carbon sequestration is essential for effectively leveraging this tool in the fight against climate change.
Emissions compensation
Emissions compensation refers to the practice of offsetting or neutralizing one's own or an organization's emissions by funding projects that reduce or remove carbon dioxide or other greenhouse gases from the atmosphere. This practice is a key component of climate change mitigation, especially in situations where complete elimination of emissions is not immediately feasible.
Carbon offsets can cover a variety of measures, including:
1. Reforestation and forestry projects: Supporting reforestation projects or sustainable forest management can sequester carbon in biomass and soil, reducing atmospheric carbon dioxide levels.
2. Promotion of renewable energy: Investing in renewable energy projects can reduce reliance on fossil fuels and thereby decrease emissions.
3. Improvement of energy efficiency: Funding energy efficiency projects, such as the adoption of better technologies or energy-saving measures, can reduce energy consumption and consequently, emissions.
4. Enhancement of industrial processes: Supporting initiatives that reduce greenhouse gas emissions from industrial processes, such as technology development or carbon capture and storage (CCS).
Carbon compensation can serve as a tool for businesses, individuals and governments to meet their climate goals and commit to more sustainable practices. However, it should not replace direct actions to reduce emissions, such as improving energy efficiency or increasing the use of renewable energy sources. Its role is more of a complementary solution until permanent emission reductions can be achieved.
Carbon sequestration methods and technologies
Carbon sequestration involves various technologies and methods for capturing and storing carbon dioxide (CO2). These methods can be categorized into biological, geological and technological solutions.

Carbon sequestration on peatlands
Afforestation of peatlands is important for several reasons, with the most significant being environmental and climate impacts:
​
1. Carbon sequestration: Afforestation of peatlands helps to capture carbon dioxide from the atmosphere. Forests act as effective carbon sinks by absorbing carbon dioxide through photosynthesis and storing it in trees and soil.
​
2. Mitigation of climate change: Afforestation significantly reduces the carbon dioxide emissions caused by peatlands. Peatlands release significant amounts of carbon dioxide as peat decomposes. By afforesting these areas, this process can be halted or its effects reduced.
​
3. Promotion of biodiversity: Afforestation improves the habitat for many species that benefit from forest ecosystems. Forested areas provide shelter and food for a diverse range of animal and plant species.
​
4. Protection of water bodies: Forests help maintain water quality and reduce erosion and the risk of flooding, which is also important for preserving nearby ecosystems.
​
5. Improvement of soil: Forest vegetation can help improve the typically acidic soil and its structure in peatlands, which can increase soil fertility and biodiversity (The variety of different organisms and ecosystems that a specific area or environment contains).
​
For these reasons, peatlands are actively being afforested around the world as part of broader climate protection efforts and sustainable development goals.
Emissions from peatlands and voluntary carbon sequestration
​
Peatlands are significant sources of greenhouse gas emissions due to the processes of peat decomposition and burning. Here are the primary sources of emissions from peatlands:
​
1. Peat decomposition:
- Aerobic decomposition: When peatlands are drained for agriculture or other land use, the peat is exposed to oxygen. This exposure leads to aerobic decomposition, where microorganisms break down the peat and release carbon dioxide (CO2) into the atmosphere.
- Anaerobic decomposition: In waterlogged conditions, such as natural wetlands, peat decomposes slowly without oxygen, releasing methane (CH4), a potent greenhouse gas.
​
2. Peat burning:
- Controlled and uncontrolled fires: In dry peatland areas, fires can ignite either intentionally (for agricultural or land use purposes) or accidentally. Peat fires can burn for extended periods and deep within the soil, releasing large amounts of carbon dioxide, methane, and other greenhouse gases into the atmosphere.
- Biomass combustion: Peat is also used as an energy source in some countries. Burning peat directly releases carbon dioxide into the atmosphere.
​
3. Land management and cultivation:
- Effects of land drainage: Draining peatlands is often done to convert them to arable land. This process causes the peat to dry out and decompose, significantly increasing carbon dioxide emissions.
- Fertilizer use: Peatland agriculture often involves the use of nitrogen-based fertilizers, which can release nitrous oxide (N2O), a very potent greenhouse gas.
​
Reducing these emissions is a key goal in the restoration and carbon sequestration efforts for peatlands. Restoring peatlands, such as by re-wetting and planting vegetation, can help reduce these emissions and enhance the ability of these areas to sequester carbon.
Voluntary carbon sequestration​
​
Voluntary carbon sequestration can be an effective way to reduce emissions from peatlands in several ways. Here are some key methods by which voluntary carbon sequestration can help:
​
1. Peatland restoration:
- Restoring moisture: Re-wetting drained peatlands helps to prevent aerobic decomposition of peat, which reduces carbon dioxide emissions. Voluntary carbon sequestration projects can fund and implement these restoration activities.
- Planting vegetation: Restoration projects can involve planting appropriate vegetation that sequesters carbon and promotes the reformation of peat. This helps to reduce both carbon dioxide and methane emissions.
2. Preventing peat fires:
- Reducing fire susceptibility: Restoring moisture reduces the flammability of peat. Voluntary projects can support fire prevention measures and monitoring, helping to prevent large peat fires and the emissions they cause.
​
3. Sustainable land use:
- Training and support for landowners: Voluntary carbon sequestration projects can provide training and support to local landowners on sustainable land use practices, reducing the need for peatland drainage and cultivation. This can include alternative farming practices that do not require peat drying.
- Economic incentives: Through voluntary carbon sequestration projects, economic incentives can be provided to landowners for preserving and restoring peatlands, making sustainable land use more attractive.
​
4. Carbon sequestration credits:
- Selling carbon credits: Voluntary carbon sequestration projects can generate and sell carbon credits. These credit systems can finance restoration projects and offer businesses and individuals the opportunity to offset their emissions by investing in peatland restoration.
- Certification and monitoring: Carbon credits can ensure that restoration measures are implemented effectively and that they have real, measurable impacts on carbon sequestration and emission reductions.
​
5. Collaboration and networks:
- Working with stakeholders: Voluntary carbon sequestration projects can collaborate with governments, NGOs, and local communities to develop and implement effective restoration strategies.
- Sharing knowledge and best practices: Projects can serve as forums for sharing information and best practices, helping to increase understanding of peatland importance and effective restoration techniques.
​
In summary, voluntary carbon sequestration can significantly reduce peatland emissions by supporting restoration efforts, promoting sustainable land use, providing economic incentives and creating carbon credit systems. These actions help restore peatlands to their natural state and enhance their ability to act as carbon sinks.
The impact of reducing emissions from peatlands on climate change
​
1. Reducing greenhouse gas emissions:
- Decreasing carbon dioxide emissions: Peatlands are a significant source of carbon dioxide emissions because, when drained and decomposed, they release stored carbon into the atmosphere. By restoring peatlands and reinstating their moisture balance, carbon dioxide emissions can be substantially reduced.
​
2. Enhancing natural carbon sinks:
- Carbon sequestration: Restoring and reforesting peatlands can improve their capacity to capture and store carbon. This increases the capacity of natural carbon sinks, which is critical for mitigating climate change.
- Growth of trees and vegetation: Afforestation and vegetation renewal can capture additional carbon dioxide from the atmosphere and store it in biomass and soil.
​
3. Preventing emissions from peat fires:
- Reducing fire susceptibility: Restored and moist peatlands are less prone to peat fires, which release large amounts of carbon dioxide, methane and other greenhouse gases into the atmosphere. Reducing the risk of peat fires can prevent these large emissions spikes.
​
4. Promoting sustainable development and biodiversity:
- Biodiversity protection: Restoring peatlands improves habitats and promotes biodiversity, which enhances ecosystem resilience and adaptability to climate change.
- Ecosystem services: Healthy peatlands provide numerous ecosystem services, such as water purification, erosion control, and nutrient cycling, which are all important for sustainable development.
​
5. Achieving global climate goals:
- Paris Agreement: Reducing emissions from peatlands is a crucial part of many countries' strategies to meet the targets of the Paris Agreement, which aims to keep global warming well below 2 degrees Celsius and to pursue efforts to limit it to 1.5 degrees Celsius.
- National and international actions: Many countries' national climate strategies and policies include peatland protection and restoration, reinforcing international efforts to combat climate change.
​
By reducing emissions from peatlands, we can effectively mitigate climate change, enhance carbon sequestration, and promote sustainable development and the preservation of biodiversity.
The role of forests in carbon sequestration
Forests act as natural carbon sinks by sequestering carbon dioxide from the atmosphere through photosynthesis and storing it in trees, soil and other forms of biomass.
​​​​
Here are some key forestry practices that can improve carbon sequestration:
​
1. Afforestation and regeneration: Active afforestation and regeneration help to increase the area of ​​the forest and the growth of trees. New trees quickly bind carbon dioxide from the atmosphere.
​
2. Preserving diversity: Preserving biodiversity in forest management is important, as diverse forests can store more carbon. This includes the preservation of old trees, the use of different tree species and the maintenance of habitat diversity.
​
3. Selective logging: Selective logging, where only certain trees are removed and other forest vegetation is preserved, helps preserve soil structure and reduce carbon emissions.
​
4. Soil treatment: Soil treatment, such as fertilization and prevention of erosion, can contribute to the preservation and growth of soil carbon stocks.
​
5. Carbon balance optimization: This includes optimizing forest planning and management so that forests retain a large carbon stock and bind more carbon dioxide than they release.
Leaving dead wood and stands: By leaving dead wood and old trees in the forest, habitats are created for many species and soil carbon stores are increased.
​
6. Forest fire management: Controlling forest fires can prevent the loss of significant carbon reserves.
​
Compared to other ecosystems, forests are usually considerable carbon stores and sinks. Their ability to bind carbon dioxide is particularly significant when considering the carbon reserves of both biomass and soil. This makes forests a key target in mitigating climate change and promoting sustainable development.
The diversity of forests
​
The diversity of forests significantly affects their ability to sequester carbon through several different mechanisms:
1. Ecosystem stability and resilience:
- Increasing resilience: Diverse forests tend to be more resilient and resistant to disturbances such as disease, pests and climate change stressors. This stability enables continuous and efficient carbon sequestration.
​
2. The combined effects of different species:
- Structure and functions: Different tree species and vegetation provide different ecosystem services and utilize resources in different ways. This increases the total biomass and carbon sequestration potential of the ecosystem.
- Nutrient cycling: Different plant species can improve soil nutrient cycling and microbiological activity, which supports tree growth and carbon storage in the soil.
​
3. Diversity of growth stages and life cycles:
- Trees of different ages: Diverse forests usually have trees of different ages, which sequester carbon at different rates. Young trees grow quickly and sequester carbon efficiently, while older trees store large amounts of carbon in their biomass.
- Understory vegetation and shrubs: Diversity also extends to understory vegetation and shrubs, which increase the forest's total biomass and carbon storage capacity.
​
4. Protective ecosystem services:
- Soil protection: Diverse forests better protect the soil from erosion and improve its structure, which reduces the release of carbon from the soil and increases its storage.
- Water economy: Different plant species have a positive effect on the forest's water balance, which promotes the health and growth of trees and thus carbon sequestration.
​
5. Ecosystem productivity:
- Photosynthesis: Diverse forests can be more productive because they use light and other resources more efficiently. This increases total carbon sequestration through photosynthesis.
- Ecological compartments: Different species fill different ecological compartments, which enables more efficient use of resources and thus greater carbon sequestration.
​
In summary, the diversity of forests improves their ability to sequester carbon in many different ways. This makes the protection and restoration of diverse forests critically important for curbing climate change and promoting sustainable development.
The ability of forests to bind carbon dioxide
In general, forests are efficient carbon sinks, and their carbon sequestration capacity can be assessed using the following factors:
​
1. Forest type and age:
- Young forests: Young forests grow quickly and bind carbon dioxide efficiently. They can bind around 10–30 tons of carbon dioxide per hectare per year, depending on the growth rate and the density of the forest.
- Mature forests: Mature forests sequester less carbon dioxide compared to young forests because the growth rate slows down, but they store large amounts of carbon in their biomass and soil. They can bind approximately 5–15 tons of carbon dioxide per hectare per year.
​
2. Forest management practices:
- Well-managed forests: Forest management practices such as thinning and planting can improve the carbon sequestration capacity of the forest. A well-managed forest can sequester more carbon dioxide compared to poorly managed forests.
- Forest renewal: Forest renewal and afforestation can significantly increase the carbon sequestration capacity of forests.
​
3. Forest location:
- Tropical forests: Tropical forests are particularly effective in sequestering carbon dioxide due to the warm climate and continuous growing season. They can bind up to 20–40 tons of carbon dioxide per hectare per year.
- Birch forests and boreal forests: These forests tend to have a lower carbon sequestration capacity than tropical forests, but they are still important carbon stores. They can bind approximately 5–15 tons of carbon dioxide per hectare per year.
​
4. The role of soil:
- Soil: Forests not only sequester carbon in trees and vegetation, but also in the soil. The soil can store a large part of the forest's carbon stock. In well-managed forests, the soil can increase carbon sequestration.
​
In general, forests can sequester approximately 5 to 40 tons of carbon dioxide per hectare per year, depending on the type, age, location and management practices of the forest. This makes forests key actors in mitigating climate change and reducing carbon dioxide from the atmosphere.
Carbon sequestration and forest loss prevention
Preventing deforestation can improve carbon sequestration in several important ways:
​
1. Preservation of carbon stocks:
- Preservation of woody biomass: Deforestation leads to the loss of large carbon stores such as woody biomass. By preventing deforestation, we preserve these carbon stocks, which would otherwise be released into the atmosphere when forests are cut down.
- Soil carbon stocks: Deforestation not only affects the tree but also soil carbon stocks. Deforestation can reduce the amount of organic matter in the soil, leading to the release of carbon into the atmosphere. Preventing deforestation preserves soil carbon stocks.
​
2. Maintaining carbon dioxide binding capacity:
- Photosynthesis: Forests bind carbon dioxide through photosynthesis, where trees and plants convert carbon dioxide into biomass. When deforestation is prevented, forests continue to sequester carbon dioxide and grow.
- Preserving growth potential: By preventing deforestation, we ensure that forests can continue to grow and sequester carbon dioxide optimally, instead of having to renew their land and growth after disturbances.
​
3. Securing the functioning of the ecosystem:
- Ecosystem services: Forests provide important ecosystem services, such as water filtration and soil protection. Maintaining these services prevents erosion and nutrient leaching that could reduce carbon sequestration.
- Biodiversity: Diverse forests can improve forest resilience and productivity, which supports long-term carbon sequestration. Preventing deforestation protects diverse ecosystems that improve the forest's ability to sequester carbon.
​
4. Renewal and restoration of forests:
- Natural restoration: Preventing deforestation enables the natural restoration and regeneration of forests. This process improves the carbon sequestration capacity of forests in the long term as forests recover and grow.
- Planting measures: Preventing deforestation can also include active afforestation and planting measures that increase carbon sequestration and forest biomass.
​
5. Less carbon dioxide release:
- Less burning and soil disturbance: Deforestation often leads to an increase in forest fires or soil disturbance, which can release large amounts of carbon dioxide. By preventing deforestation, we reduce the risk of these disturbances and thus the release of carbon dioxide.
Preventing deforestation improves sequestration of carbon dioxide by preserving the carbon stocks of forests, continuing to sequester carbon dioxide through growth, securing the functioning of the ecosystem and preventing the release of carbon dioxide through forest disturbances. This makes combating deforestation a central part of curbing climate change and achieving the goals of sustainable development.
Reliability of emissions offset projects
The reliability of offset projects varies depending on the project type, implementer and certification methods. Evaluating the reliability of these projects involves several key factors:
​
1. Project transparency:
- Documentation: Reliable projects provide comprehensive documentation that includes detailed information about project implementation, calculation methods and emission reduction accounting.
- Reporting: Approved projects regularly publish reports that outline the progress of the project, the amount of emissions reduced, and other relevant details.
​
2. Project quality and implementation:
- Sustainability: Reliable projects focus on long-term impacts and are designed to be sustainable. For instance, reforestation projects that consider the needs of the local ecosystem and communities are often more dependable.
- Risk management: Good projects account for potential risks, such as forest fires or diseases, and include plans for managing and minimizing these risks.

3. Additionality and verifiability:
- Additionality: The project must demonstrate that the emission reductions are additional, meaning they would not have occurred without the project. This is a crucial factor in assessing the reliability of a project.
- Verifiability: Emission reductions must be measurable and verifiable. This means that the measurement and reporting methods used are accurate and reliable.
​
4. Diverse benefits:
- Multiple benefits: Reliable projects often provide additional benefits, such as improved local habitats, preservation of biodiversity, or community development. These additional benefits can serve as an indicator that the project is well-managed and responsible.

Reliable projects meet stringent criteria and offer verified, measurable, and additional emission reductions.
