Clean Car Standards - Pavley, Assembly Bill 1493

Background

On June 30, 2009 the U.S. EPA granted California authority to reduce greenhouse gas emissions standards for new motor vehicles, beginning with the current model year.

The first California waiver request was made in December 2005 and was denied in March 2008 by U.S. EPA.  U.S. EPA's decision was based on an interpretation of the Clean Air Act finding that California did not have a need for its greenhouse gas emission standards to meet “compelling and extraordinary conditions.”

Back in September 2004 the ARB’s Board passed regulations to reduce greenhouse gases (GHG) from new passenger vehicles starting in 2009. These regulations were authorized by the 2002 legislation Assembly Bill 1493 (Pavley).  The regulations would reduce GHG emissions from California passenger vehicles by about 22 percent by 2012 and about 30 percent by 2016. Prior to June 30, 2009, these regulations had been stalled by automaker lawsuits and the U.S. EPA’s refusal to grant California an implementation waiver.  ARB plans to update this website as information becomes available.
