In a move to protect the environment through self-regulation, SAE International, on behalf of industry, is pursuing a voluntary program under which automakers could tout compliance to an evaluation procedure outlined in an SAE standard (J2727) aimed at reducing refrigerant leakage from vehicle A/C systems. An “SAE J2727-certified low-leak A/C” logo could be used by qualifying automakers on window stickers and in advertising materials. A design standard, J2727 (currently being updated) would assign leakage values to different types and designs of A/C system components. An A/C system using components of a combined value not exceeding certain U.S. EPA-proposed limits would qualify for use of the logo. The EPA, which is working with SAE on the program, is suggesting voluntary limits ranging from 25-40 g/vehicle/year for 2008 to 15-25 g/vehicle/year by 2010. The agency currently has no regulation on vehicle A/C refrigerant leakage.
