SACRAMENTO – Following the June 2009 Board adoption of the cool cars regulation, stakeholders raised several new issues involving performance of electronic devices as they may affect public safety. After listening to this input and accounting for the legal deadline to finalize the rule, today we are announcing that the AB 32 “cool cars” rulemaking will cease. Instead, the Board will pursue a performance-based approach as part of its vehicle climate change program to reduce CO2 from air conditioning and provide cooler car interiors for California motorists
