EVALUATE POTENTIAL CARBON SEQUESTRATION AND GREENHOUSE GAS REDUCTIONS FROM ADOPTING NRCS CONSERVATION PRACTICES

NRCS Conservation Practices included in COMET-Planner are only those that have been identified as having greenhouse gas mitigation and/or carbon sequestration benefits on farms and ranches. This list of conservation practices is based on the qualitative greenhouse benefits ranking of practices prepared by NRCS.
Begin by naming your project and selecting your state and county
Select the class of conservation practices that best describes the practice you
would like to evaluate
Cropland Management
Grazing Lands
Woody Plantings
Cropland To Herbaceous Cover
Select a NRCS Conservation Practice Standard and a Practice Implementation
that best describes your system. You may add multiple practices. If you would like
to add a practice under a different class of practices, return to Step 2.

How are your carbon sequestration and greenhouse gas emission reduction estimates calculated?
Emission reduction coefficients were largely derived using a sample-based approach and model runs in COMET-Farm, which utilizes USDA entity-scale greenhouse gas inventory methods. Coefficients were generalized by multi-county regions defined by USDA Major Land Resource Areas. Emissions estimates represent field emissions only, including those associated with soils and woody biomass as appropriate, and do not include off-site emissions, such as those from transportation, manufacturing, processing, etc. More information on quantification methods can be found in the COMET-Planner Report.

Each emission reduction is calculated using the following equation:

Emission reduction = Area (acres) * Emission Reduction Coefficient (ERC)

Recommended use of COMET-Planner
This evaluation tool is designed to provide estimates of the net greenhouse gas reductions of specific conservation practices included in the CDFA Healthy Soils Program ( https://www.cdfa.ca.gov/oefi/healthysoils/). Please note that a comprehensive assessment of site specific conditions may not be accounted with this tool.
