Legislation in the United States to combat global warming has suffered a serious setback after Republicans in the Senate blocked efforts to bring the bill for a final vote.
Democratic Party leaders in the Senate fell 12 votes short of the 60 required to end a Republican delaying tactic on the measure.
The bill would have put a cap on carbon emissions, introducing a target cut of 70 per cent by the middle of the century.
White House spokeswoman Dana Perino said it would be wrong to support a bill that damaged the economy.
"The President supports tackling the problem of climate change in a way that will be effective, meaning that it would actually reduce greenhouse gas emissions around the world in a way that would not harm our economy," she said.
