Ford...has been attacked by its own sustainability committee for failing to do enough to cut vehicular greenhouse gas emissions, in spite of a 4.8 per cent drop in the US this year. In response to the company's annual sustainability report, issued on Tuesday, the committee of academics, environmental lobbyists and socially responsible investment groups said Ford's efforts to reduce carbon dioxide emissions "fall far short of the necessary response to climate change". The committee called for clear targets to improve fuel economy, but welcomed efforts made to cut CO2 emissions from factories.
