The Washington State Department of Agriculture developed WaCSE for the Washington State Conservation Commission to use in the Sustainable Farms and Fields (SFF) program. Intended users are the Conservation Commission, conservation districts, growers, and anyone interested in reducing agricultural greenhouse gas (GHG) emissions. This interactive tool estimates the reduction of GHG emissions from different conservation practices across Washington’s diverse counties.
Values were determined by the United States Department of Agriculture’s Natural Resources Conservation Service (NRCS). NRCS reviewed field studies and applied a sample-based metamodeling approach to calculate potential GHG emission reduction coefficients. These values are derived from county-rectified major land resource areas (Swan et al. 2024).
NRCS and Colorado State University developed two tools to estimate impacts on GHG and soil carbon from conservation practices.
COMET-Farm is a field-specific tool that requires detailed management and parcel history to estimate the impact of conservation practices.
COMET-Planner is a simplified tool that evaluates GHG emission reductions by county rather than by a specific field with specific management history. It provides a more generalized, less accurate GHG reduction estimate, but is easier to use.
WaCSE uses the COMET-Planner dataset and provides identical estimates. With WaCSE, however, data can be compared between multiple counties and multiple practices at once. WaCSE provides data in tables and bar graphs that can easily be downloaded in spreadsheets and PDFs. WaCSE also helps the user understand their GHG reduction estimate by providing a calculator to convert the emissions data into equivalents from home energy use, consuming gasoline, charging smartphones, and more!
Negative values indicate a loss of carbon or increased emissions of GHG (Swan et al. 2024).
