The objective of this project will be to quantify the populations of foams in California by the types of blowing agents utilized (ODSs, HFCs, CO2, and others) and a detailed accounting of the amount of foam stock by product category (e.g, small appliance refrigeration) including both assoicated banks and annual emissions. Specifically, for each application, the emissions rates (during foam production, installation, and lifetime), turnover rates, end-of-life, disposal emissions, sector-growth rates, refrigerant substitution rates, and banks will be generated. The timescales associated with emissions from foams (during lifetimes and after disposal) will be examined, as well as the effect of disposal method (shredding, landfiling, incineration) on Greenhouse Gas (GHG) emissions.
