The UK is writing carbon dioxide targets into law. But the draft Climate Change Bill is insufficiently strong to ensure the UK plays a fair role in avoiding dangerous climate change. We interviewed the then Environment Secretary, David Miliband, and put his responses to Dr Alice Bows (Tyndall Centre) and Martyn Williams (senior parliamentary campaigner, Friends of the Earth). – Why is the government using a target that is based on outdated science? – Is it right that the Bill would allow the government to meet 50% of its targets by buying up emissions credits from abroad? – Why aren’t emissions from aviation and shipping included in the Bill?
