This report investigates the clarity and completeness of federal reporting on climate change funding. The Office of Management and Budget (OMB) annually reports on federal spending in four categories: technology for emission reduction, science for climate understanding, international assistance, and tax expenditures. However, the Climate Change Science Program (CCSP) only reports on science. This examination covers federal climate change funding from 1993 to 2004, analyzing changes in total and categorized funding, and the comparability of this data over time, as well as changes in agency-specific funding and its comparability.

This report provides a detailed examination of federal climate change funding, focusing on the period between 1993 and 2004. It scrutinizes the reporting methods employed by the Office of Management and Budget (OMB) and the Climate Change Science Program (CCSP), highlighting areas where clarity and completeness could be improved. The analysis includes trends in overall funding, categorized expenditures, and agency-specific allocations, utilizing charts and tables to illustrate the findings. The report aims to inform a better understanding of how federal resources are directed towards climate change initiatives.
