Environment groups throw down the green gauntlet to London mayoral candidates
Meanwhile, Matthew Spencer, director of environmental think tank Green Alliance, said London was at risk of becoming a victim of its own success. "London is a dynamic city, but if it's to remain a healthy place to live and work it also has to become a greener city," he said. "London is unusual in the UK in having most of the powers it needs to make itself greener without waiting for central government. We've suggested 20 practical ways the next mayor can use their power on behalf of London citizens seeking a more liveable city."
