The National Highway Traffic Safety Administration published a corrected version of its final rule on 2017 emissions standards and fuel economy improvements for light-duty vehicles, which could affect school district white fleets.
NHTSA said in the Federal Register that the original final rule on Greenhouse Gas (GHG) emissions and Corporate Average Fuel Economy for 2017 and later model-year cars and trucks that was published earlier this week contained an incorrect value for vehicle lifetime miles traveled.
The correcting amendment is effective Dec. 14 of this year.
NHTSA said the CAFE standards portion of the mandate will increase fuel economy to at least 54.5 mpg by model-year 2025. By the same year, GHG emissions are expected to be reduced by one-half the level emitted by model-year 2010 cars and trucks. The EPA said the program will reduce domestic consumption of oil by 4 billion barrels and will reduce GHG by 2 billion metric tons, with a net social benefit estimated to be worth up to $451 billion.
But the Institute for Energy Research said the GHG rule does not affect global warming in "any meaningful way" and called the cost-benefit calculations as well as the entire rule "fatally flawed."
