EPA approves California greenhouse gas rules

Four days after the US House of Representatives narrowly passed a legislation aimed at curbing climate change, the US Environmental Protection Agency has granted California’s request to apply its own tough emission standards for motor vehicles. The approval is to boost fuel efficiency and reduce greenhouse gases linked to climate change.

When California requested the Clean Air Act waiver from the EPA in 2005 it was denied by the Bush administration. The Tuesday's approval is a reversal of the 2005 decision. While acknowledging California's need for a tight emissions programme, the EPA said this decision marked a return to the "traditional legal interpretation of the Clean Air Act."

Now the California state can start implementing a 2004 law that requires automakers to increase the fuel efficiency of cars by 40 per cent.

EPA administrator Lisa Jackson said, "After review of the scientific findings, and another comprehensive round of public engagement, I have decided this is the appropriate course under the law."
