Mayor Boris Johnson Monday 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 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 (内燃机)," said Johnson. He said at a press
conference the world's cities consume 75 percent of the world's energy and produce
80 percent of the emissions which cause climate change. "The problem of our planet is
an urban problem," Johnson said.
He said the British capital wants to use the Olympics "to drive the greening and the
improvement of our city" and noted that London is committed to reduce carbon dioxide
emissions by 60 percent by 2025.
Johnson said the key measure was being taken to solve problems relating to housing
and commercial buildings, which accounted for 70 percent of carbon dioxide emissions
in London. This involved retrofitting (翻新) -- installing lagging -- in large numbers
of public buildings.
Johnson proclaimed himself a "passionate cyclist" and said he would push ahead
with cycle superhighways around London.
London's air quality problem, he said, was caused by vehicle emissions from 8,300
worn and used diesel (柴油) buses, which could be replaced by low-carbon vehicles.
In addition, there were also 32,000 taxis running on diesel fuel, which could be replaced
by electric vehicles.
Johnson said there would be a few programs in the next few years to produce a
"cleaner, greener" bus for the city. "The age of the diesel bus has got to be over in
London."
