COMET-Farm: Whole Farm and Ranch Carbon and Greenhouse Gas Accounting System

Sadie Shelton

COMET-Farm is a farm-level carbon and greenhouse gas accounting system and calculator for the United States. It uses information on management practices on an operation together with spatially-explicit information on climate and soil conditions from USDA databases (which are provided automatically in the tool) to run a series of models that evaluate sources of greenhouse gas emissions and carbon sequestration. It is based on the methods described in the report Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory.
