The UK’s political leaders have pledged to work together to combat climate change, whatever the election result. In a joint statement, David Cameron, Ed Miliband and Nick Clegg said climate change was one of the most serious threats facing the world. They said climate change threatens not just the environment but also security, prosperity and poverty eradication. They have promised to end coal burning for power generation in the UK – unless it uses new clean-up technology. Environmentalists say the pledge is significant because it quells some of their fears that the Conservatives might adopt a more climate-sceptic line.
