In late September, the California Air Resources Board (CARB) voted unanimously to adopt a strong set of regional targets for passenger vehicle emissions reduction under SB 375, the state's anti-sprawl law. The historic vote was the culmination of a two-year effort which included the entire Regional Targets Advisory Committee process and report, intense research by modeling experts, proposed targets from metropolitan planning organizations, and public workshops around the state. In the end, CARB adopted the staff-recommended targets for the big four regions, including the Bay Area's Metropolitan Transportation Commission (MTC) -- 13-16% by 2035, and 10% for the San Joaquin Valley. These percentages represent a reduction in per-capita greenhouse gas emissions from passenger vehicle trips, and will be achieved through regional planning that will align housing growth goals with transportation funding.

For MTC, which in advance of the CARB meeting voted to adopt a 15% reduction in per capita emissions from passenger vehicles (from a 2005 baseline), this is a very significant change. The region's adopted Regional Transportation Plan (RTP) otherwise would have increased these emissions by 2% in 2035.

At the same meeting, CARB approved a 33% renewable portfolio standard for energy utilities by 2020. This means that the state's investor-owned utilities like PG&E, which are now required to source 20% of their electricity from renewables, will have to increase that percentage significantly over the next 10 years. This policy is expected to reduce carbon dioxide emissions by about 12-13 million tons/year beginning in 2020. While the SB 375 targets will remove only 3 million tons/year in 2020, it will ramp up to 15 million tons/year by 2035.
