Cap and Trade for Cars Is Coming to the Northeast
Nine Northeastern states and the District of Columbia committed yesterday to forming a cap-and-trade system for the transportation sector, embarking on one of the most ambitious regional programs ever undertaken to cut carbon dioxide.

California has special authority under the Clean Air Act to set vehicle emissions standards.
