Called the "Improved R134a Project" (IRCRP), the goal will be develop technologies to reduce atmospheric leakage by 50% and improve system efficiency by 30%. Two teams, one to address emissions and one to address efficiency, will include experts from Tier-1 and 2 automotive suppliers, OEMs, Mobile Air Conditioning Society (MACS) members, and refrigerant, hose coupling, and fitting suppliers. The IRCRP will begin later this year and continue through 2006.
