Step 1: Begin by naming your project and selecting your state and county
Step 2: Select the class of conservation practices that best describes the practice you would like to evaluate
Step 3: 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.
Conservation Practice Standard (CPS):
Conservation Practice Implementation:
Step 4: Enter the acreage associated with each conservation practice you selected
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 generalized estimates of the greenhouse gas impacts of conservation practices and is intended for initial planning purposes. Site-specific conditions (not evaluated in this tool) are required for more detailed assessments of greenhouse gas dynamics on your farm. Please visit COMET-Farm if you would like to conduct a more detailed analysis.
