Principal Investigator / Author(s): Katy Wolf, Ph.D.
Contractor: Institute for Research and Technical Assistance

Topic Areas: Greenhouse Gas Emissions, Stationary Sources
As part of the California Air Resources Boardís (CARBís) responsibilities under AB 32, the Global Warming Solutions Act of 2006, the agency sponsored projects focused on developing an inventory of greenhouse gases (GHGs) in California. This project, which is part of that effort, involved developing bottom up estimates of emissions of GHGs for 2010 and 2020 for solvent, fire protection and other applications. The approach used here relied on local air district permits and information from equipment installers and suppliers to generate emission estimates for solvents and fire protection equipment and the bank of agents in fire protection equipment. The results demonstrated that emissions will decline in both of the applications that were analyzed over the period because of trends already underway. Cumulative emissions from solvent and fire protection applications are estimated at 0.186 and 0.363 million metric tons of carbon dioxide equivalent respectively over the ten year period. Cumulative emissions from other applications that were analyzed are estimated at 0.017 million metric tons of carbon dioxide equivalent. The project also involved investigating non-GHG alternatives and alternatives that are reasonably cost effective were identified for most applications. CARB could adopt policies to reduce emissions further, particularly in solvent applications.
