Yesterday, a quiet public hearing on a hot August day in Washington D.C. drew a surprisingly large crowd. The official reason for the hearing, conducted by the National Highway Transportation and Safety Administration (NHTSA), was to take comment on the Environmental Impact Statement (EIS) for revised Corporate Average Fuel Economy (CAFE) standards. A lawsuit forced NHTSA to draft an EIS that assessed global climate change impacts – including health – from improved fuel economy in the U.S. car and light truck fleet.
The 400-page document is technical, turgid, incomplete and misleading, and asserts that it is not possible to distinguish between the future health and climate impacts of a 41 mpg fuel economy versus the present 25 mpg. Needless to say, EDF does not agree with that conclusion or the methods used to come to it, but the comments at the hearing were far broader than just the EIS. Most striking was the lineup of citizens who called on NHTSA to take definitive action on climate change to help protect their future.
