Vehicular air pollution: greenhouse gas emissions.

Existing law imposes various limitations on emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. Existing law generally designates the State Air Resources Board as the state agency with the primary responsibility for the control of vehicular air pollution. Existing law required the state board to adopt regulations that achieve the maximum feasible reduction of greenhouse gases emitted by passenger vehicles and light-duty trucks and any other vehicles determined by the state board to be vehicles whose primary use is noncommercial personal transportation in the state. This bill would state the intent of the Legislature to enact legislation that would direct the state board to reassert its authority to regulate tail pipe emissions if the upcoming federal midterm review process on fuel economy and greenhouse gas emissions standards results in a weakening of the proposed standards.
