London eyes 'greenest' city by 2012

SEOUL: Mayor Boris Johnson yesterday outlined plans to make London "the cleanest, greenest city on Earth" by the 2012 Olympics and called for commitments from other world cities at a climate change conference.

Leaders of the world's 40 largest cities, plus 17 affiliate municipalities, are meeting in Seoul this week for a summit on combating global warming - the third to be held since 2005.

"What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine," said Johnson.
