FAST-GHG is a fertilizer and soil tool designed to help quantify greenhouse gas emissions in crop production. Developed by Cornell faculty in partnership with researchers at Environmental Defense Fund and The Nature Conservancy, FAST-GHG quantifies how soil management practices can reduce greenhouse gas emissions. In particular, the FAST-GHG methodology and online calculator provide valuable support to companies that aim to reduce GHG emissions in their agricultural supply chains but who may have limited information about the emissions generated in the production of commodities they sell. The methodology has been carefully and transparently documented to allow any individual to implement the accounting method.
In September 2020, FAST-GHG was included in Walmart’s Project Gigaton to allow Walmart suppliers to calculate their avoided emissions from adopting soil health practices.
