Adaptation: CCAP's Winkelman says transportation policy should complement federal cap-and-trade program

With Americans driving more and more each year, there is a new push on Capitol Hill for legislators to go beyond vehicle efficiency improvements and alternative fuels mandates be developing ways to encourage less driving in the United States. In his new book, "Growing Cooler: The Evidence on Urban Development and Climate Change," the Center for Clean Air Policy's Steve Winkelman says this can be achieved through smarter urban planning. During today's OnPoint, Winkelman, manager of adaptation and transportation at CCAP, explains how new urban areas can be developed to maximize the emissions reduction benefits of a cap-and-trade program. Winkelman explains why urban sprawl could undermine steps being taken on the local and federal levels to combat global warming and urges action in this year's transportation bill.
