Copenhagen

I've finally arrived in Copenhagen, having had to do the last bit on the train, since they don't allow you to cross the bridge to Zealand (the island on which Copenhagen sits) on a cycle, so my trip wasn't completely zero carbon.

But I think this is an important illustration that individuals alone cannot defeat climate change - the reason why I could not cycle on the bridge is a political one, and it is a combination of individual action and politics that will be effective.

The rumours here are that a Copenhagen agreement, if we do get one, will be even worse than Kyoto, retaining its bad aspects - the offsets which mean there can be no true cap on emissions, and removing the good ones - the binding emission reduction targets, which would be replaced by voluntary ones.

Tomorrow I am making a presentation (10am to noon) and a press conference (3pm) on my journey and the solutions I have discovered, at the Klimaforum .
