"Since 1993, OMB [Office of Management and Budget] has reported over $154 billion in funding for federal climate change activities, spread across the government--raising questions about fragmentation, overlap, or duplication. GAO [Government Accountability Office] was asked to review federal climate change funding. This report examines (1) reported federal funding from 2010 to 2017 and the extent to which reports on such funding are clearly linked to the federal fiscal exposure to climate change; (2) the extent to which selected agencies reported climate change funding that supports programs where addressing climate change is the primary purpose; and (3) the extent to which the primary purpose programs are fragmented, overlapping, or duplicative. GAO reviewed OMB climate change funding reports; analyzed budget justifications for six agencies--the Departments of Agriculture, Commerce, Defense, and Energy; the National Aeronautics and Space Administration and the National Science Foundation--representing 89 percent of OMB-reported climate change funding in fiscal year 2014; analyzed documents on primary purpose programs against GAO's fragmentation, overlap, or duplication criteria; and reviewed GAO's prior work on fiscal exposures."
