California drops rule on heat-deflecting windows

  • 07-Apr-2010 03:33 EDT

In the face of opposition from individuals and groups, CARB (California Air Resources Board) has decided against imposing a rule that would have required new MY2012 and later vehicles to be equipped with windows that deflect or absorb solar radiation. Opposition to the rule, adopted in June 2009, centered on the concern that coatings on windows would compromise the performance of in-vehicle electronic devices that transmit or exchange signals with the outside world. The goal of the rule was to reduce use of air-conditioners and thus reduce CO2 emissions. CARB said it will pursue a different path to reduce the CO2 impact of vehicle AC systems.
