Now, the Trump administration basically is making the argument that any benefit from regulating tailpipe emissions of greenhouse gases don't justify the costs.

In the release the administration put out with this repeal, it says, quote, EPA now finds that even if the U.S.

were to eliminate all greenhouse gas emissions from all vehicles, there would be no material impact on global climate indicators through 2100.

How do you respond to that?

We risk falling behind?

What has the endangerment finding and the, you know, subsequent regulations, what have they actually accomplished?

I mean, last year, U.S.

greenhouse gas emissions rose after falling for a couple of years.

Have they made a big difference?

This is obviously going to play out in the legal system.

There's already been a big lawsuit against this move.

Do you think the repeal will hold up in court, if you had to guess?

All right.

Thank you so much for your time.

Along with repealing the endangerment finding, the EPA also eliminated all of the federal greenhouse gas emission standards for vehicles that were based on that finding.

To tell us more about how that will affect the auto industry and the kinds of cars and trucks they make, I talked with Rachel Moncrief.

Rachel is the interim CEO at the International Council on Clean Transportation.

It's a nonprofit research organization working toward cleaner road, marine, and air transportation globally.

And I posed the same burning question to Rachel.
