On April 2 the Supreme
Court ruled that the Environmental Protection Agency had the authority to regulate carbon dioxide and other greenhouse gases from automobiles. The primary way that can be done, carmakers and
environmentalists say, is to increase automobile fuel economy. As a result, Detroit carmakers, which have a long history of fighting regulations, are saying they want an active role in the movement to
reduce the damage vehicles do to the environment.
Representatives of environmental groups are glad to see Ford's latest steps, but have not forgotten that the automaker has a history of pulling back on promises of building more efficient vehicles.
