The Top 10 Cities Leading the Way on Climate Change

Boyd Cohen, CEO of CO2 IMPACT, a carbon origination company based in Vancouver, Canada, breaks down what these cities have done to reduce carbon emissions. Denver is #5:

"According to a city press release, Denver's Fast Track "is the most ambitious transit initiative in U.S. history building 119 miles of new light rail" within just a few years. Along with strong sustainability objectives, Denver is projecting a 37% increase in job growth by 2030, showing that the low carbon economy is alive and well."

And what is San Diego doing to be included?

"San Diego intends to take advantage of its great climate and abundant sun by adding 50 megawatts of renewable energy by 2013 (much of it being new solar capacity) while achieving a 50 megawatt reduction in energy use through efficiency and demand side management measures."
