ProfileKeith Paustian is University Distinguished Professor in the Department of Soil and Crop Sciences at Colorado State University. A major focus of his work involves modeling, field measurement and development of assessment tools for soil carbon sequestration and greenhouse gas emissions from soils. He has published over 250 journal articles and book chapters. Research activities include development of models and inventory methodology used to estimate US soil C and N2O emissions that are reported annually by EPA to the UNFCCC; development of a web-based tool (COMET-FarmTM) for estimating on-farm greenhouse gas (GHG) emissions and carbon sequestration used by USDA (http://cometfarm.nrel.colostate.edu/) and project-scale systems for GHG assessment of sustainable land management projects in developing countries (http://www.unep.org/cbp_pim/). He served as Coordinating Lead Author for the IPCC 2006 National Greenhouse Gas Inventory Methods and the IPCC 2003 Good Practice Guidance for LULUCF and on two National Academy of Sciences panels (2010, 2018) dealing with land use and greenhouse gas measurement issues. He is a Fellow of the Soil Science Society of America and 2015 recipient of the Soil Science Society of America’s Outstanding Research Award.
