CO2 case before US Supreme Court

Car manufacturers could be forced to improve fuel efficiency
The US Supreme Court is to consider whether to force the government to regulate carbon dioxide emissions from energy producers and cars.

A dozen states and environmental groups asked the court to take up the case after a lower court ruled against them.

They argue the onus should be on the government's environmental protection agency to limit CO2 emissions.

They say CO2 is the primary greenhouse gas causing a warming of the Earth and so should be categorised a pollutant.

The US government says that CO2 is not a pollutant under federal laws and that even if it was, it would have discretion over whether or not to regulate it.
