The greenhouse gas limits, which would be the same as the federal government has proposed for vehicles nationally, should cut those auto emissions by a third more in 2025 than required under current standards. To meet the new limits, the board staff anticipates the auto industry will make greater use of advanced hybrid technology, stronger and lighter materials and improved emission control equipment.
If oil companies don't reach an agreement with the state to voluntarily install alternative fueling stations, such as for hydrogen fuel cells, the new rules will also require them to do so when a certain number of cars using that fuel is reached. The outlets could be placed at an existing gasoline station or a free-standing site.
The California clean car rules also address emission standards for gasoline and diesel-powered vehicles by extending limits on greenhouse gas emissions and smog forming pollutants. Again, by 2025 all new vehicles must emit 34% fewer global warming gases and 75% fewer smog forming emissions. California has over 26 million cars and the top five smoggiest metropolitan areas in the country.
The California Air Resources board estimates that the initial increase in cost will be offset by an average of $6,000 worth of fuel savings over a vehicle’s lifetime. (Think Progress, 1/30/2012, LA Times, 1/28/2012)
