Saving The Climate Must Begin In Cities

Cities account for 75% of the world's enegry use. A few successful strategies to reduce emissions could cause massive changes in the environment.

"Cities are also the place where most of the world's people live. This year, the proportion of the world population living in urban areas passed 50% for the first time. And because of their dense transport and power systems, cities account for 75% of the world's energy use. But cities also have the power to change rapidly through schemes that make big cuts in emissions. Look at London's anti-congestion car toll...

...Other cities that have led successful initiatives include Toronto, which uses nearby lake water to cool its downtown buildings, and Seattle, the champion greenhouse-gas reducer with a 48% cut from 1990 to 2000. Even lowly Woking, near London, has built a leisure centre powered by a hydrogen fuel cell that emits only water."
