WASHINGTON, August 27, 2013 – The Climate Change Program Office of the U.S. Department of Agriculture's (USDA) Office of the Chief Economist today released and requested public comments on the report Science-Based Methods for Entity-Scale Quantification of Greenhouse Gas Sources and Sinks from Agriculture and Forestry Practices. The report is the work of 38 scientists from across academia, USDA and the federal government, who are experts in greenhouse gas (GHG) estimation in the cropland, grazing land, livestock and forest management sectors. The report has undergone technical review by an additional 29 scientists.

The report outlines a set of consensus methods for quantifying GHG emissions and carbon storage at the local farm, ranch or forest scale. It is important that the methods exhibit scientific rigor, transparency, completeness, accuracy, and cost effectiveness, as well as consistency and comparability with other USDA GHG inventory efforts. The report can be downloaded at www.usda.gov/oce/climate_change/index.htm. A Federal Register Notice is included on the web site and provides detailed instructions for comment submission. Comments must be received within 45 days of the August 28, 2013 publication of the Federal Register Notice.
