Overview
This method enables ACCUs to be generated from adopting new management practices that increase the amount of organic carbon stored in soils.
The science
Soil organic carbon forms when plants and microbes decompose organic matter such as roots, crop residues and manure. Practices like minimal tillage, cover cropping, and rotational grazing can help retain organic inputs and reduce carbon loss. When these practices are sustained, soil carbon can build up, improving soil structure, fertility, and water-holding capacity.
Key Project Steps
- Engage an appropriately qualified professional to measure baseline soil carbon using core samples and lab testing.
- Prepare a land management strategy and register project with the Clean Energy Regulator.
- Introduce eligible practices that enhance carbon inputs or reduce carbon losses. There are numerous eligible practices within the method.
- Re-measure soil carbon after several years and use models to estimate change.
- Prepare reports on project actions and calculated abatement. ACCUs are issued for verified increases compared to the baseline.
Co-Benefits
Projects using this method can:
- Improve soil health and productivity.
- Enhance drought resilience.
- Boost nutrient cycling and microbial activity.
