The state needs to curtail carbon dioxide emissions with help from fuel efficiency, he said.
"It's a proposal that attacks the states' right to protect people from risky pollution, one that no one -- not the American public, not the states, not even most automakers -- really wants, and one that's being presented to the public under the false and easily discredited guise of improving public safety", the statement continued. We value the public's input as we engage in this process in an open, transparent manner. Those standards target a doubling of the fuel economy standards to 50 miles per gallon.
The Environmental Protection Agency said in a statement that relaxing mileage standards in the years ahead would give "the American people greater access to safer, more affordable vehicles that are cleaner for the environment".
The agency suggests keeping the Obama-era standards would add $2,340 to the cost of owning a new auto, "and impose more than $500 billion in societal costs" on the United States economy over the next 50 years.
The proposal argues that freezing the Obama-era standards at 2020 levels through 2026 will save consumers money and increase safety on the nation's roads.
The state coalition, led by California Attorney General Xavier Becerra, includes legal representatives from jurisdictions that have adopted California's more stringent vehicle emissions standards.
Schwarzenegger weighed in shortly after the Trump administration announced that it would move to roll back former President Obama's fuel economy and global warming standards for cars. "For 48 years - since one of my heroes, then-Governor Ronald Reagan, requested it - California has had a waiver from the federal government to clean our own air", Schwarzenegger wrote in a statement on Twitter.
Gillis says manufacturers have done a good job of meeting ambitious mileage standards and consumers have benefited.
"We can't comment on a determination we haven't seen, but remain absolutely convinced that one national program is the preferred policy path", Bainwol contended.
The Trump administration believes that expenditure would be offset by reductions of several thousand dollars in the cost of new vehicles.
"There are compelling reasons for a new rulemaking on fuel economy standards for 2021-2026", said Transportation Secretary Elaine L. Chao. Electric cars and trucks still account for a tiny fraction of those sold, and driver preference for SUVs, along with relatively low gas prices, have inhibited progress there.
At the same time, it plans to block California from putting its own mileage standards into place.
What started as a mandate in the mid-1970's to reduce foreign imports of oil morphed into a costly and unworkable environmental regulation thanks to bureaucrats in the previous Administration and in Sacramento.
