Let the cars run free!

The momentous end to the federal government’s legal authority to fight climate change makes it official.

The United States will essentially have no laws on the books that enforce how efficient America’s passenger cars and trucks should be.

That’s the practical result of the Trump administration’s yearlong parade of regulatory rollbacks, capped on Thursday by its killing of the “endangerment finding,” the scientific determination that required the Environmental Protection Agency to regulate greenhouse gases because of the threat to human health.

Oh who cares about human health. What a silly thing to protect! The important health is the health of cars! They need to run free every day.

“The U.S. no longer has emission standards of any meaning,” said Margo T. Oge, who served as the E.P.A.’s top vehicle emissions regulator under three presidents and has since advised both automakers and environmental groups.

“Nothing. Zero,” she added. “Not many countries have zero.”

We’re special. It makes us so proud!

Car buyers could still vote with their wallets, demanding more fuel-efficient cars. California has vowed to sue to maintain stricter standards. And the Department of Transportation still regulates fuel economy under rules meant to conserve oil.

But last year, the Trump administration proposed weakening the fuel economy standards to largely irrelevant levels. The Republican-controlled Congress also set civil penalties for violations at $0, essentially making them voluntary for automakers. In addition, Congress last year blocked California’s clean-car rules.

Dirty air is better! It builds character.

Lee Zeldin, the E.P.A. administrator, called the end of the finding “the single largest deregulatory action in the history of the United States.” He accused Democrats of having launched an “ideological crusade” on climate change that had “strangled entire sectors of the United States economy,” particularly the auto industry, which has struggled to sell electric vehicles.

While pretending climate change/global warming is fictional or trivial or both is not ideological at all.
