Mayor Bloomberg shows no sign of slowing down his drive to reduce New York City’s carbon emissions, which is of course a good thing. He’s now set to announce that municipal buildings in NYC will switch to solar power and move from dirty regular oil to a less-damaging biodiesel. Other mayors (and North American federal leaders!) should follow NYC’s example of emission cutting.

On Monday, Bloomberg said the city will issue a request for proposals for a pilot program to install solar panels on city-owned buildings in hopes of generating 2 megawatts of solar capacity _ offsetting about 320 tons of emissions per year, equal to taking more than 50 U.S. cars per year off the streets. The city will not pay for the installation but will buy electricity from the provider.
