No matter what gloss is put on it, there can be little doubt that the Copenhagen Summit has failed. It was supposed to produce a legally binding treaty. Instead it has produced an 'accord'. The whole thing cost £130 million to put on and was attended by 15,000 people. Planting £130 million of trees would have been a better use of the money.
I never thought it would end in anything else but abject failure. It was never going to be possible for a committee of 15,000 to come up with anything other than a giant piece of fudge. If it had been a summmit of 192 presidents and prime ministers, each with two advisers, it would have been difficult enough. But with 15,000 people? Never.
The main outcome of the summit is the guarantee that they will now become regular events. As Iain Murray writes: "The future of climate change summits is assured".
