* Chris Huhne deserves congratulations for winning the cabinet battle over climate targets, as does the prime minister for backing him. The decision will give a boost to the coalition's tattered green credentials. David Cameron must now get on with the urgent task of fast tracking the policies that will ensure that the UK's bold climate targets are met. This means strengthening the energy bill to slash energy waste in our homes and communities, putting electricity decarbonisation by 2030 at the heart of electricity market reform and ensuring that the fight against climate change is central to UK transport policy.  andy atkins  Executive director, Friends of the Earth
