As the world grapples with climate change, innovative solutions are being sought to reduce greenhouse gas emissions and promote sustainable practices. One such solution is the trading of soil carbon credits, a mechanism that could potentially offer farmers both profit and the opportunity to contribute to environmental sustainability. This emerging concept allows farmers to engage in carbon markets by sequestering carbon in the soil through improved farming practices and receiving credits in return selling carbon elsewhere. Can farmers trade soil carbon credits?
What are Soil Carbon Credits?
Soil carbon credits are a form of carbon offset that farmers can earn by capturing carbon dioxide from the atmosphere and storing it in the soil through specific agricultural practices. These practices include no-till farming, crop rotation and cover cropping—methods that improve soil health and increase its ability to absorb carbon.
Each carbon credit represents the equivalent of one metric ton of CO2 removed or prevented from entering the atmosphere. Once carbon is sequestered, it can be sold to businesses or governments needing to offset their carbon emissions. This trade helps fund sustainable farming practices and renewable energy, making it an attractive financial incentive for farmers.
The Role of Soil Carbon Credits in Sustainability
Increased urgency to act on climate change
- Climate change is a pressing issue that requires immediate attention.

- A surge in schemes to pay farmers and landowners for carbon is underway.
- The Farm Carbon Calculator tool is available for farmers to help them understand their carbon position.
Can farmers trade soil carbon credits? How Soil Carbon Credits Work
Soil captures CO2 in a natural cycle
- The length of time carbon stays in the soil varies depending on factors like climate and soil composition.
- Carbon farming methods like no-till farming and planting cover crops can slow down carbon loss and even increase carbon levels in soil.
- Studies show that agriculture has emitted ~100 billion metric tons of CO2 over the past 200 years.
- Soil carbon sequestration is a natural process that can be enhanced through sustainable farming practices.
Carbon credits are generated through sustainable farming practices
- Farmers can generate carbon credits by adopting regenerative farming practices that enhance soil health and sequester carbon.
- Project developers bring those credits to carbon markets where they sell them to emitters, providing farmers with additional income.
- Some may falsely claim to achieve certain carbon reductions without proper verification, making it essential for farmers to know what to consider.
- Farmers can get carbon credits from five sources: crop growers, livestock producers, forest managers, wetland managers, and urban forestry managers.
Carbon credits can be traded for profit
- Carbon credits can be sold to companies looking to offset their carbon emissions.
- The carbon credit market is growing, with increasing demand from companies looking to reduce their carbon footprint.
- Farmers can earn additional income by selling their carbon credits.
- Carbon credits can be traded on carbon markets, providing a new revenue stream for farmers.
Benefits of Soil Carbon Credits for Farmers

- Soil carbon sequestration can also improve soil fertility and structure.
- Farmers can benefit from improved soil health through increased crop yields and reduced soil erosion.
- Sustainable farming practices can also improve biodiversity and ecosystem services.
Implementing Soil Carbon Credits
Getting started with carbon credits farming
- Find the right carbon program that aligns with your farming practices and goals.
- Determine the baseline data needed to quantify and monitor emissions reductions.
- Plan for the changes your farm needs to implement regenerative agricultural practices.
- Partner with a reputable carbon certifier to ensure highest standards in carbon credit measurement and accounting.
Identifying suitable soil carbon schemes
- Research and identify suitable soil carbon schemes that align with your farming practices and goals.
- Consider factors such as scheme requirements, payment structures, and verification processes.
- Evaluate the credibility and reputation of the scheme provider.
- Choose a scheme that provides fair payment and transparent verification processes.
Implementing sustainable farming practices to generate carbon credits
- Implement sustainable farming practices that enhance soil health and sequester carbon.
- Consider practices such as no-till farming, cover cropping, and crop rotation.
- Monitor and measure the impact of your practices on soil carbon sequestration.
- Adjust your practices as needed to optimise carbon sequestration.
Key Considerations for Soil Carbon Credits
Permanence of carbon sequestration
- Permanence refers to how long the carbon is kept out of the atmosphere.
- The permanence of carbon is far easier to quantify and verify for woodlands and forestry than for soils.
- Improvements to soil organic carbon carries a higher risk of reversal compared to trees and hedgerow.
Additionality of carbon credits
- Additionality is essential for the quality and credibility of the carbon offset market.
- It’s about whether the payment a farmer or landowner receives plays a decisive role in helping remove carbon from the atmosphere.
Carbon leakage and its implications
- Carbon leakage refers to the possibility that a project could result in an increase of emissions elsewhere.
- Changes in farm management practice might deliver more carbon sequestration in one place, but could have the effect of creating a bigger carbon footprint elsewhere.
Accreditation and Regulation of Soil Carbon Schemes
Importance of third-party verification and accreditation
- Third-party verification and accreditation are essential for ensuring the credibility and integrity of soil carbon schemes.
- Accreditation ensures that schemes meet rigorous standards for carbon sequestration and verification.
- Verification ensures that carbon credits are accurately measured and accounted for.
Overcoming Challenges in Soil Carbon Markets
Addressing response rates and adoption rates of sustainable practices
- Response rates and adoption rates of sustainable practices can be improved through education and incentives.
- Farmers need to be aware of the benefits of sustainable practices and the potential for carbon credit sales.
- Incentives such as payment for ecosystem services can encourage farmers to adopt sustainable practices.
Motivations for practice adoption and concerns about soil carbon markets
- Farmers’ primary motivations for adopting beneficial farming practices were economic profitability and intergenerational resilience due to maintaining healthy soils.
- Farmers who participated in carbon markets adopted practices for various reasons, but the ability to participate in a carbon market was not the primary reason.
- Farmers viewed carbon market payments as helpful, especially for those who were already doing the on-farm activities.
The Future of Soil Carbon Credit Trading
Despite the challenges, the market for soil carbon credits is growing, supported by increasing demand for carbon offsetting from corporations, governments, and environmentally-conscious consumers. Governments and private sector organisations are investing in carbon credit markets, and new technologies are emerging to improve carbon measurement and verification processes.
What Are Agricultural Soils?
Agricultural soils refer to the layers of soil that are cultivated or used for growing crops. These soils are essential for plant growth, as they provide plants with nutrients, water, and support. Healthy soils are rich in organic matter, maintain good structure, and support biodiversity, all of which contribute to more soil quality and better agricultural productivity.
The Importance of Agricultural Soils
- Source of Nutrients: Agricultural soils provide essential nutrients like nitrogen, phosphorus, potassium, calcium, and magnesium, which plants need to grow. The fertility of the soil, which is determined by its nutrient content, directly affects crop health and yields.
- Water Retention and Drainage: Soils also play a key role in water management. They retain moisture for plant roots, reducing the need for frequent irrigation. Good soil structure helps ensure proper drainage, preventing waterlogging while avoiding drought stress in plants.
- Soil Carbon Storage: Soils act as carbon sinks, sequestering carbon from the atmosphere and reducing greenhouse gas concentrations. Through practices like no-till farming and cover cropping, agricultural soils can store significant amounts of carbon, contributing to climate change mitigation.
- Biodiversity and Ecosystem Services: Healthy soils support a wide range of organisms, including earthworms, bacteria, fungi, and insects. These organisms contribute to soil fertility, enhance nutrient cycling, and help break down organic matter, all of which support plant growth and resilience.
Farmers, particularly those already implementing sustainable practices, have the potential to benefit financially while contributing to a global effort to mitigate climate change. In the future, policy frameworks that support carbon credit trading, alongside advancements in agricultural practices and technology, could further incentivise this shift toward sustainability.
Soil carbon credit trading offers a promising way for farmers to generate income while promoting environmental sustainability. Through the adoption of carbon-sequestering agricultural practices, farmers can both profit and contribute to addressing climate change. While challenges such as verification, upfront costs, and market volatility remain, the growth of carbon markets and government support could make soil carbon credits an increasingly valuable opportunity for farmers worldwide.
