18 US states sue Trump administration over emission rules for vehicles

Environmental Protection Agency said last month that Obama-era rules, which aim to raise efficiency requirements to about 50 miles per gallon by 2025, would be revisited. But the states say it acted “arbitrarily” in changing the course on greenhouse gas regulations.

Eighteen US states have sued President Donald Trump’s administration over its push to “reconsider” greenhouse gas emission rules for the country’s auto fleet, launching a legal battle over one of former President Barack Obama’s efforts to address climate change.

Environmental Protection Agency (EPA) administrator Scott Pruitt in April said he would revisit the Obama-era rules, which aim to raise efficiency requirements to about 50 miles per gallon by 2025. Pruitt’s agency said the standards are “based on outdated information” and that new data suggests “the current standards may be too stringent”, The Washington Post reported.

But in the lawsuit, the states contend that the EPA acted “arbitrarily and capriciously” in changing the course on greenhouse gas regulations.

“This phalanx of states will defend the nation’s clean car standards to boost gas mileage and curb toxic air pollution,” California Governor Jerry Brown (D) said in a statement announcing the suit, which was filed on Tuesday in the US Court of Appeals for the District of Columbia Circuit.

The lawsuit comes amid a larger struggle over climate policy regarding US cars and light trucks. The Trump administration has drafted a proposal that would freeze the federal standards at 2021 levels, leaving them well below levels targeted under Obama.

The Trump administration plan, which is not final, would also challenge California’s ability to set its own fuel-efficiency rules. California has a separate set of standards that, because of the state’s huge car market, have pushed automakers to produce more fuel-efficient vehicles.

According to figures from the California New Car Dealers Association, California’s 20,48,000 new car sales in 2017 represented about 12 percent of the 17 million-plus cars sold in the United States last year.

Twelve other states participating in the lawsuit — including New York — have followed California in setting more stringent emission standards. The total market involved is 36 percent of sales in the United States, according to Margo Oge, a former EPA official who helped the agency set auto regulations during the Obama years.

“If you are a car company, that is a pretty big deal. You have uncertainty how this thing is going to work out, and today you have to be investing in cars you’re going to build five years from now,” she said.

The current standards were created under a 2011 agreement reached among the Obama administration, California officials and automakers. If enacted, they would avert 6 billion tons of carbon dioxide emissions from vehicles sold between 2012 and 2025, according to the EPA.
