London Mayor Boris Johnson recently outlined (概述) 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 met in Seoul (首尔) two weeks ago for a summit (最高级会

谈) on combating (与……斗争) global warming, the third one held since 2005.

"What we should do in Seoul is that we will stop the endless addiction of mankind to the internal

combustion engine," said Johnson.

An urban (城市的) problem

"The problem of our planet is an urban problem," Johnson said, calling for "serious rcsults" in Seoul.

our city" and that London is committed to reduce carbon emissions by 60 percent by 2025.

A substantial program

Johnson proclaimed himself a "passionate cyclist" and said he would push ahead (推动) with cycle

buses, which could be replaced by low-carbon vehicles. There were also 32,000 taxis running on diesel
