Hybrid Taxis in NY to Reduce Emissions from Cabs by 50%

New York Mayor Michael Bloomberg is implementing a plan to reduce carbon emissions from the taxi fleet by 50% by 2012. By October 2008, all new vehicles entering the fleet must achieve at least 25 miles per gallon.

As part of this effort, Yahoo has donated a fleet of 10 hybrid taxis to New York. It's also sponsoring a competition to identify the greenest city in America.
