"The Trump administration's plans for addressing vehicle emissions may not be as good for society as an Obama administration rule, according to a review released Monday by the Environmental Protection Agency’s (EPA) independent science board.
The analysis from the Science Advisory Board (SAB) found “significant weaknesses in the scientific analysis” of the 2018 Safer Affordable Fuel-Efficient Vehicles rule.
The Trump administration has argued that reducing fuel economy requirements will allow automakers to produce more affordable cars. As customers replace older gas guzzlers with new cars, officials argued, overall emissions output will decline.
Those new emissions targets would be rolled out alongside a measure that would freeze average fuel economy at 37 miles per gallon (mpg) by 2026 rather than the 54.5 mpg ordered by the Obama administration."
