The Washington Post reported that the environmentalists were placing yellow tickets on 15,000 SUVs in the capital and surrounding areas. The tickets made by the Chesapeake Climate Action Network say SUVs emit 40 percent more pollution than an average car.
Half of the ticket is a preprinted postcard addressed to Ford Motor Co. chief William Clay Ford Jr. It urges the company to keep its promise to introduce an efficient hybrid SUV, the Ford Escape, next year.
The initial goal of the campaign was to pressure automakers not drivers, but the drivers have been receptive, the activists said.
Climatologists have pointed to Washington's large number of SUVs as a key contributor to its Code Red smog alerts this summer, the Post reported.
