SCAG is addressing the climate change challenge through implementation of recent State legislation. In 2006, Assembly Bill No. 32 (AB 32), the California Global Warming Solutions Act, passed into law requiring that statewide GHG emissions be reduced to 1990 levels by 2020. This would represent reducing about 30 percent from business-as-usual emission levels projected for 2020. On December 11, 2008, the California Air Resources Board (ARB) adopted a comprehensive Scoping Plan outlining the state’s strategy to achieve the 2020 GHG emission reduction target.
Senate Bill No. 375 (SB 375), effective January 2009, also intends to implement a portion of AB 32 to reduce the GHG emissions from the use of autos and light trucks through land use and VMT Reduction policies. In addition, as a long-term statewide goal, Governor’s Executive Order (S-3-05) requires that by 2050 California reduce GHG emissions to 80 percent below the 1990 level.
