This week the makings of a change in the culture of Washington will be on display, and as the Presidentâ??s words here indicate there could be no better example than todayâ??s announcement of a breakthrough on fuel economy and greenhouse gas emissions standards. Whereas these issues seemed destined to be the subject of eternal political clashing just last year, today the President was joined on stage by the Presidents, CEOs, or other top executives from Ford, Toyota, General Motors, Honda, Chrysler, BMW AG, Nissan, Mercedez-Benz, Mazda, Volkswagon, and the United Auto Workers to announce a new consensus.
