The California Air Resources Board (CARB) recently conducted the workshop “Cool Paints and Solar Reflective Glazing” to discuss approaches to reduce emissions from mobile air conditioners, including solar reflective paints and window glazing.

Discussion focused on the planned regulatory approach for these reductions that resulted from California Assembly Bill 32. This legislation, signed into law in 2006, directed ARB to reduce California’s greenhouse gas emissions from all sources.

The use of air conditioners in motor vehicles greatly increases vehicular fuel consumption which translates into greater carbon dioxide emissions. Therefore, an obvious proposal to reduce carbon dioxide emissions has been to reduce air conditioner use. The proposed measure would require manufacturers to equip new vehicles with technologies that will reduce the solar heat gain of a vehicle parked in the sun. Some approaches to reducing interior temperatures include solar reflective paints and window glazing.

During the workshop, CARB staffers informed stakeholders about the proposed action, solicited input as to the most effective way to author the regulation and gathered information about the anticipated cost. The Automotive Service Association (ASA) participated in the workshop.

Comments regarding the proposed regulation are being accepted in writing or by e-mail from interested stakeholders. Comments or questions can be directed to Dr. Marijke Bekken at mbekken@arb.ca.gov. A copy of the comments should be sent to Sharon Lemieux at sclemieu@arb.ca.gov. Comments may also be faxed to (626) 459-4480.
