The Carbon Cycle Interagency Working Group (CCIWG) supports carbon cycle research across the Federal Government and is responsible for defining program goals, setting research priorities, and reviewing the progress of the research programs that contribute to carbon cycle science. As part of USGCRP’s sustained assessment process, the CCIWG led and coordinated the production of the Second State of the Carbon Cycle Report, the latest decadal assessment of the carbon cycle and its connection to climate and society in North America. 

Fourteen federal agencies and departments are part of CCIWG program activities. CCIWG works closely with other USGCRP Interagency Groups and engages with U.S. and international partners.
