Leaders of local governments re-affirmed their commitment to reducing greenhouse gases, unanimously approving a historic environmental resolution Monday at the U.S. Conference of Mayors in Miami Beach.

The 259 mayors in attendance voted in favor of a resolution titled "100% Renewable Energy in American Cities," agreeing to set a goal of powering their communities exclusively by wind, solar, geothermal and wave energy by the year 2035.
