US House supports emissions bill

The US House of Representatives has passed a historic climate change bill aimed at reducing the country's emissions.

The legislation will put curbs on pollution and apply market principles to attempts to tackle global warming.

Mr Obama earlier said the Clean Energy and Security Act, which seeks cut emissions by 17% by 2020 and force a shift from fossil fuels to renewable sources, would "open the door to a new, clean energy economy" and reduce US dependence on imported oil.
