On the campaign trail in New Hampshire on Friday, Sen. Barack Obama (D-IL) called for a National Low Carbon Fuel Standard (NLCFS) similar to one created in California earlier this year by Governor Arnold Schwarzenegger.

According to a news release, Obama’s proposal would require that all transportation fuels sold in the U.S. contain 5 percent less carbon by 2015 and 10 percent less carbon by 2020. The NCLFS would also create an incentive for the production of more flexible-fuel vehicles that can run on ethanol and more plug-in hybrid vehicles that run on electricity.

“It will take a grassroots effort to make America greener and end the tyranny of oil. This Earth Day should mark the beginning of a nationwide effort to harness our technology, our ingenuity and our will to achieve energy independence in our time,” Obama said.
