Taking the lead in London

London mayor Ken Livingstone is at it again, this time with a detailed plan for how London will cut its carbon emissions by 60% over the next twenty years. As Britain's capital, this is not only a highly symbolic move but with significant practical implications for tackling climate change. The plan focuses on current technologies and methods, which are all immediately do-able.

I'm all for blue-sky thinking, such as cloudseeding ships to create more cloud to reflect sunlight, but the fact remains that decentralized energy and energy efficiency still have a long way to go and they can do the job without much fuss. Transport, offices, homes, the energy supply - if we each do a little, we all do a lot.

The mayor said:
"Londoners don't have to reduce their quality of life to tackle climate change, but we do need to change the way we live"

Too right.
