GLRPPR Sector Resource: US Cropland Greenhouse Gas Calculator
US Cropland Greenhouse Gas Calculator
Researchers at the W.K. Kellogg Biological Station, including Claire P. McSwiney, Sven Bohm, Peter R. Grace, and G. Philip Robertson, developed the Farming Systems Greenhouse Gas Emissions Calculator, a simple web-based tool to help users make economically and environmentally sound decisions. To calculate the greenhouse gas impact of different crop rotations and varying management practices, begin by moving your cursor over the map of the US below and click on a county. The next screen will show an estimate of the greenhouse gas cost (CO2 equivalents) of a 'baseline scenario' corn-soybean rotation in that county, based upon data from the USDA. To see how different management practices and farm conditions alter the greenhouse gas cost of the system, you can then change the crop, tillage type, fertilizer rate and environmental variables to create new scenarios.
