Politicians in America have passed laws to increase the fuel efficiency of new vehicles by up to forty per cent. It's the first such legislation in more than thirty years. Supporters say it will help break America's 'addiction to oil'. This report from Rajesh Mirchandani:

Congress also ordered a massive increase in the production of ethanol, an alternative fuel for cars: up sevenfold over fifteen years.

The Bill had bipartisan support. The most senior Democrat in the Senate, Harry Reid, said America must begin to break its addiction to oil and reverse global warming, and that this Bill would make strides towards that.

Senate Democrats didn't have it all their own way though. In order to win enough votes they had to drop parts of the Bill that called for billions of dollars in taxes on oil companies. This may yet prove to be a sticking point. The lower House of Representatives has approved the bill with the tax package and will now have to vote again on the reduced measure.
