As Congress continues to debate a federal climate policy, cities and counties throughout the United States have already begun to implement energy efficiency standards and policies to help reduce emissions. During today's E&ETV Event Coverage of the USEA's 19th Annual Energy Efficiency Forum, Trenton, New Jersey Mayor Douglas Palmer, Seattle, Washington Mayor Greg Nickels, and York, Pennsylvania Mayor John Brenner, explain what their cities have done to improve energy efficiency and reduce emissions. The panelists give their take on why there is such a disparity between federal and local action and also discuss the issues that may arise once a federal climate bill is passed and there are a patchwork of regulations throughout the country. The panel is moderated by E&ETV host Monica Trauzzi.
