Radiohead's frontman Thom Yorke has launched a Europe-wide campaign for climate change action in Brussels.
The Big Ask Europe brings Friends of the Earth groups from 17 European countries together in a bid to bring legally binding annual emissions cuts.
Yorke has been part of the campaign since its UK launch in 2005.
In a statement, he said: "We will never wake from the nightmare of climate change unless our national governments and the European Union act.
'Play our part'
"They are the only ones who can put the structures in place that will help us tackle climate change."
He added: "That is why we are launching The Big Ask in 17 countries across Europe. By committing to annual cuts in our emissions at a national and European level we can play our part in tackling climate change, and set an example for the rest of world to follow."
In 2005, Yorke campaigned on behalf of the Big Ask, which called on the UK government to reduce British CO2 emissions by 3% a year.
Radiohead played a benefit concert for the Friends of the Earth campaign at London's Koko club in May 2006.
Friends of the Earth UK Director, Tony Juniper said: "I hope MPs and the Government listen to the thousands of people across the UK who support The Big Ask and strengthen the law."
The government revealed in 2006 the UK was unlikely to meet its target of reducing CO2 emissions by 20% by 2010.
