As you're probably aware, Labour is deadly serious about climate change. They're seriously thinking about possibly making a start.
Their latest attempt comes in the form of the Climate Bill, a serious piece of legislation which will set a series of legally binding carbon budget periods lasting five years each. Unfortunately the draft target for 2050 is inadequate: a 60% reduction on 1990 levels, and more pertinently, the bill excludes Aviation - the fastest growing source of greenhouse gasses in the UK. The draft bill - before consultation - had a built-in loophole you could fly a jumbo through, and everyone knew it.
