Trump weakens fuel economy standards, rolling back key U.S. effort against global climate change

The Trump administration on Tuesday weakened One of the nation’s most aggressive efforts to combat global climate change , releasing new fuel efficiency standards for cars and trucks that handed a victory to the oil and gas industry.


The new rule, from the Environmental Protection Agency and Transportation Department, will soon be plunged into litigation as environmental groups and states with stricter standards, led by California, decide to challenge it.

If the administration’s policy survives those fights, it might spare automakers from having to satisfy ambitious gas mileage and emissions requirements put in place in 2012 under President Obama.

It is among the most important steps the administration has taken to reverse an existing environmental policy.

The proposal may be a dialed-down version of the one the administration originally planned.

Instead of proposing zero improvements in fuel efficiency in coming years, it might require automakers to extend fuel economy across their fleets by 1.5% a year, with a goal of achieving a mean of 40 miles per gallon by 2026.

That’s still a serious departure from current rules, which mandate annual increases of 50, reaching a mean of 54 mpg by 2025.
