EPA Administrator Lee Zeldin, acting on behalf of the Trump administration, proposed rescinding the 2009 endangerment finding on July 29, 2025. The Clean Air Act‘s federal regulations on emissions from vehicles, power plants, and industries are based on this finding, which categorizes greenhouse gas emissions as a threat to human health. With the elimination of these regulations, the proposed rollback is expected to save the industry $52 billion annually. Zeldin described it as a historic deregulatory step. Trump’s climate rollbacks could spark legal chaos, especially given the scale of changes targeting tailpipe emissions, vehicle efficiency standards, and Biden-era power plant rules.

The plan would also nullify California’s 2035 ban on new gasoline-powered car sales and end penalties in the fuel economy program. Key sectors affected include transportation (29% of U.S. emissions), electric power (23%), and heavy industries like steel and cement (23%).

What is the Response of the Industry?

Automakers, represented by the Alliance for Automotive Innovation, are reviewing the proposal. They seek a balance between environmental responsibility and market conditions. Ford, for instance, stressed the importance of stable standards to support $197.6 billion invested in U.S. EV and battery production. Some utilities, such as Duke Energy, back the rollbacks. They argue that relaxed coal ash and emissions regulations would lead to substantial cost savings.

In contrast, renewable leaders like NextEra Energy, aiming for zero emissions by 2045, warn the move could tilt markets back toward coal and natural gas. Trade groups are divided. The Edison Electric Institute is calling for regulatory consistency, while the American Petroleum Institute welcomes the repeal. Meanwhile, the U.S. Chamber of Commerce remains cautious, noting potential economic instability.

Legal and Economic Challenges

Reversing the endangerment finding will likely face steep legal resistance. The finding was upheld by the Supreme Court in 2007, and environmental groups argue that overturning it contradicts established scientific consensus. Trump’s climate rollbacks could spark legal chaos, especially as states like California prepare to challenge the repeal. This could result in a fragmented regulatory landscape and years of litigation.

Companies that have already committed to long-term emissions compliance investments, especially in the electricity industry, are concerned. The rollback might undermine investments worth $197.6 billion in EVs and jeopardize the stability of the energy market. Long-term consumer costs may also rise as a result. The estimated 7 billion metric tons of avoided emissions reductions from current auto regulations emphasize the environmental effects even more.

Further Consequences

The plan aims to reduce short-term costs for consumers and businesses as part of a larger deregulatory agenda. But it stands in stark contrast to global climate pledges.

The rollback runs the risk of increasing public health expenses and causing environmental harm, even though it might momentarily lower car prices. Today’s industries must balance immediate cost savings with long-term risks of negative legal, economic, and environmental effects.
