The math on why the Trump administration’s fuel standards report is seriously flawed – Christopher Knittel

Fuel economy standards are an important way for the U.S. to combat climate change. However, a 2018 study conducted by the Trump administration proposes hitting the pause button on regulations, potentially leaving billions of dollars in benefits on the table.

This is a significant change from the Obama administration, which ramped up prior fuel economy standards. That administration mandated the fleet-wide fuel economy of passenger vehicles and light trucks to reach 54.5 miles per gallon by 2025. The federal government’s cost-benefit analysis, completed in January 2017, concluded that this was technologically feasible and that benefits exceeded costs by over US$90 billion.

The current administration challenges that conclusion and recommends freezing standards at model year 2020 levels through 2025. Their analysis finds that the costs exceed the benefits by over $170 billion – a difference of over $260 billion from the previous report.

Who is right? The answer matters, because fuel economy standards are the last remaining major federal regulation to fight greenhouse gas emissions. The current administration has eliminated other regulations related to clean power and is promoting coal consumption. If the Obama administration’s analysis is correct, then pausing fuel standards will cost the economy money and impact the environment. If the Trump analysis is correct, then this may be the right call. There is a lot at stake.
