Speaker: Valerie Karplus, MIT. Cars and light-duty trucks are a major contributor to the climate problem in the United States, but what role will they play in a solution? Come learn and share your thoughts on what the new fuel economy (CAFE) standards, incentive programs for alternative fuels, and a potential U.S. national climate policy could mean for the carbon footprint of personal vehicle transport. We'll review the latest developments and compare policy options, then open the floor for a lively discussion.
