Publishing its response to a three month public consultation on its draft Climate Change Bill, the Department for Environment Food and Rural Affairs pledged to make the Committee on Climate Change more powerful and said that its target to cut carbon emissions 60 per cent by 2050 could be made even more stringent.
Other changes to the bill include making the Committee more independent from government with the power to appoint it's own staff and a requirement to publish all its analysis and advice to government.
The governnment would also be required to report annually to parliament and to explain to parliament if it does not accept the committee's advice.
"We need to step up the fight against climate change and we need to do it fast," said Environment Secretary Hilary Benn.
"The draft bill we set out earlier this year, and have now refined, is a ground breaking blueprint for moving the UK towards a low carbon economy.
"It will bind us to legally enforceable emissions reduction targets at home, while giving us greater clout at the international negotiating table.
"I am extremely grateful for the invaluable input from the three Parliamentary committees, and from industry and the wider public that has brought us to this point. Thanks to their efforts we will now have a Bill that is stronger, more effective and more transparent," he said.
