As California implements the climate change mitigation program, CARB has developed a variety of greenhouse gas monitoring and measurement capabilities to support California's short- and long-term climate goals. Measurements of these gases can help identify sources, evaluate the emissions from these sources, identify new emission reduction strategies, and track progress in reducing emissions. These efforts provide crucial information to help inform various elements of the program, including information to understand source characteristics; evaluate and inform CARB's greenhouse gas emission inventory; identify, implement, and validate effective emission mitigation strategies; evaluate program effectiveness; as well as track greenhouse gas emission trends in the state.
California's Greenhouse Gas Research Program utilizes regional, local, and source-level monitoring and measurements to inform California's climate protection program. These efforts are critical for the success of AB 32 and SB 32 programs, and provide useful information for policy analysis and program inputs. CARB utilizes three major components to advance the state of knowledge:
