Environment & Climate Change

Harvard Project on Climate Agreements Director Robert N. Stavins delivered a presentation titled "Climate Change: Efficiency and Equity," at The Graduate Institute in Geneva, Switzerland, on November 29, 2011. The talk was one in the Geneva Environmental Dialogue Series of public keynote lectures that the Institute holds annually on a theme related to the international environment. The theme for the 2011–2012 term is "Justice and the Environment."

"Because CAFE standards increase the price of new cars, the standards have the unintentional effect of keeping older — dirtier and less fuel-efficient — cars on the road longer. This is counterproductive.

Also, by decreasing the cost per mile of driving, CAFE standards — like any energy-efficiency technology standard — exhibit a rebound effect — namely, people have an incentive to drive more, not less, thereby lessening the anticipated reduction in gasoline usage."
