Rule Pitched for Electricity, Less-Polluting Transport Fuels

By Published On: March 28, 2008

A draft low-carbon fuel standard, floated by the California Air Resources Board this week, aims to set ground rules for measuring the carbon emission levels of electricity and natural gas used in vehicles, as well for other non-traditional transportation fuels. The rule would hold utilities and other fuel providers responsible for meeting the standard, which would require the fuels’ carbon content by 2020 to be at least 10 percent lower than that of traditional vehicle fuels, like gasoline and diesel. “We are trying to address how every fuel fits into the standard, and looking beyond 2020 to 2025 and 2030,” explained John Courtis, Air Board alternative fuels manager, in a March 25 workshop. The proposed regulation would measure non-traditional transportation fuels against the carbon content of either gasoline or diesel. When used in cars, gasoline would be used for the comparison. For fuel used in trucks and other heavy vehicles, diesel fuel would serve as the yardstick.
