The farm carbon calculator allows farmers to calculate their carbon footprint including both emissions and sequestration from a variety of data sources whuch include fuels, electricity, machineries, fertilizers, etc. It shows output in various level including scope 1, 2, 3 emissions, emission hotspots and nitrous oxide and methane emissions. The calculator can be used by farmers growing livestock, arable, etc and in any soil type in any place. Benchmarking and monotoring farm GHG emissions can enable it to analyze the emissions and reduce emissions accordingly. It not only reduces emissoions but also enhances energy efficiency while increasing production.
