An anonymous reader quotes a report from The New York Times: The Trump administration is expected on Tuesday to announce its final rule to roll back Obama-era automobile fuel efficiency standards, relaxing efforts to limit climate-warming tailpipe pollution and virtually undoing the government’s biggest effort to combat climate change. The new rule, written by the Environmental Protection Agency and the Department of Transportation, would allow vehicles on American roads to emit nearly a billion tons more carbon dioxide over the lifetime of the cars than they would have under the Obama standards and hundreds of millions of tons more than will be emitted under standards being implemented in Europe and Asia.
Trump administration officials have raced to complete the auto rule by this spring, even as the White House is consumed with responding to the coronavirus crisis. President Trump is expected to extol the rule, which will stand as one of the most consequential regulatory rollbacks of his administration, as a needed salve for an economy crippled by the pandemic. […] The new rule, which is expected to be implemented by late spring, will roll back a 2012 rule that required automakers’ fleets to average about 54 miles per gallon by 2025. Instead, the fleets would have to average about 40 miles per gallon. To meet the new number, fuel economy standards would have to rise by about 1.5 percent a year, compared to the 5 percent annual increase required by the Obama rule. The industry has said it would increase fuel economy standards by about 2.4 percent a year without any regulation. The new standard would lead to nearly a billion more tons of planet-warming carbon dioxide released and the consumption of about 80 billion more gallons of gasoline over the lifetime of the vehicles built during the terms of the rule, according to a recent draft of the plan. The report says about 20 states are expect to sue the Trump administration to undo the rule in a case expected to be resolved by the Supreme Court in the coming years.
