Now that California is on record as mandating a 25 percent cut in the state's greenhouse-gas emissions by 2020 – a move that made headlines worldwide four months ago – leaders here are starting to lay out how they intend to hit that ambitious mark. First up: requiring transportation fuels sold in California to contain less carbon, a major greenhouse gas.
Gov. Arnold Schwarzenegger (R) announced Tuesday that he will issue, within weeks, an executive order that sets a new "low carbon fuel standard" in the state. Aimed at petroleum refiners and filling stations, the new standard will give them 13 years, until 2020, to cut the carbon content of the fuels they sell for passenger vehicles by 10 percent.
The intent is twofold: to stimulate investment in alternative low-carbon fuels, and to curtail actual carbon emissions from tailpipes, which the governor said account for about 40 percent of the state's total.
"This is going to stir billions in investment – inviting technology companies of all kinds to come up with innovative ideas to reduce carbon emissions," says Eric Heitz, president of the Energy Foundation, a partnership of seven foundations dedicated to advancing energy efficiency and renewable energy. "It puts market forces to work to find the lowest costs and the best methods with a clear environmental goal.... It [also] eases US vulnerability to volatile price fluctuations driven by foreign political events." The entire world community, he predicts, will be watching California's efforts to curb greenhouse-gas emissions, which many scientists say are responsible for global warming.
California is the world's ninth largest emitter of the greenhouse gases that trap heat in the atmosphere. In unveiling the new standard for fuel content, Governor Schwarzenegger said a year-in-the-making white paper showed the importance of addressing the transportation sector.
