“The EPA's rollback of greenhouse gas emissions standards is projected to save Americans $1.3 trillion.”

WASHINGTON – Alongside President Trump in the White House's Roosevelt Room, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced the single largest deregulatory action in U.S. history. In this final rule, EPA is saving American taxpayers over $1.3 trillion, eliminating both the Obama-era 2009 Greenhouse Gas (GHG) Endangerment Finding and all subsequent federal GHG emission standards for all vehicles and engines of model years 2012 to 2027 and beyond. The final rule will save Americans over $1.3 trillion by removing the regulatory requirements to measure, report, certify, and comply with federal GHG emission standards for motor vehicles, and repeals associated compliance programs, credit provisions, and reporting obligations that exist solely to support the vehicle GHG regulatory regime.

WASHINGTON – Today, March 20, the U.S. Environmental Protection Agency announced final national pollution standards for passenger cars, light-duty trucks, and medium-duty vehicles for model years 2027 through 2032 and beyond. These standards will avoid more than 7 billion tons of carbon emissions and provide nearly $100 billion of annual net benefits to society, including $13 billion of annual public health benefits due to improved air quality, and $62 billion in reduced annual fuel costs, and maintenance and repair costs for drivers.

On February 12, 2026, U.S. Environmental Protection Agency finalized its rescission of the 2009 Greenhouse Gas Endangerment Finding, which served as a prerequisite for regulating emissions from new motor vehicles and new motor vehicle engines. This is the single largest deregulatory action in U.S. history and will save Americans over $1.3 trillion.

More than forty years of experience with the Clean Air Act has shown that America can build its economy and create jobs while cutting pollution to protect the health of our citizens and our workforce. Most recently, EPA's peer-reviewed 2011 study found that clean air programs established by the 1990 CAA amendments are expected to yield direct benefits to the American people which vastly exceed compliance costs. The study's central benefits estimate in 2020 exceeds costs by a factor of more than 30-to-1, and the high benefits estimate exceeds costs by 90-to-1.

A coalition of more than 20 U.S. states, along with 10 dozen cities and counties, filed a legal challenge Thursday against the U.S. Environmental Protection Agency (EPA), contesting the agency's rescission of the 2009 Greenhouse Gas Endangerment Finding. The EPA finalized its rescission on Feb. 12, 2026, describing the action in official materials as the "single largest deregulatory action in U.S. history" and projecting cost savings of more than 1.3 trillion U.S. dollars.

Attorney General Jeff Jackson joined a coalition of 24 attorneys general in challenging an EPA rollback that the agency's own analysis shows will raise fuel costs and cost consumers more than it saves. The EPA's own analysis shows that eliminating vehicle pollution standards will cost consumers nearly $1.5 trillion in higher fuel and vehicle maintenance costs.

The Trump administration's decision today to repeal greenhouse gas emissions standards for cars and trucks will raise costs for American families and businesses by billions of dollars in the coming years. Today's rule wipes out $61 billion a year in total consumer savings for passenger vehicles.

White House press secretary Karoline Levitt framed the repeal as a way to lower costs for Americans, saying it would save the public roughly $1.3 trillion in part by making new vehicles cheaper. She estimated average savings of more than $2,400 on a light‑duty car, truck or SUV.

An analysis by Resources for the Future (RFF) indicates that if the EPA conducted a cost-benefit analysis using updated electricity demand projections, the repeal of the Carbon Pollution Standards would fail a traditional cost-benefit test. The climate and health damages from this regulatory repeal will be 4–8 times the savings from reduced compliance costs, leading to a total net cost of $128.9 billion (2024 US dollars) through 2050 to US society in their central case.

The administration projects $1.3 trillion in reduced compliance costs and claims vehicle savings of about $2,400, while removing EV-related regulatory pressure. The administration estimates the repeal could save Americans $1.3 trillion by reducing regulatory requirements. Vehicle owners could see average savings of $2,400 per car, according to the EPA.

The EPA's “regulatory impact analysis” assumed that rolling back tailpipe rules would save automakers around $1.3 trillion in manufacturing costs, which they would pass on to consumers, lowering the sticker price of cars. What Trump did not say, but was buried in an analysis by his own EPA, is that the repeal would increase fuel and repair costs by $1.5 trillion between now and 2055, more than wiping out the potential sticker price benefits.

The American Public Health Association (APHA) states that federal government actions are dangerously turning back progress on lowering greenhouse gas emissions, and that EPA's plan to roll back the 2009 Endangerment Finding and Greenhouse Gas Vehicles standards deliberately ignores decades of science research and rulings, putting current and future generations at risk for premature death and compromised health.

The American Lung Association highlights that the regulatory landscape has changed dramatically with drastic consequences for air quality and lung health due to EPA's proposed rules to repeal greenhouse gas emission standards and weaken other air pollution limits for fossil fuel-fired power plants. These actions would reverse key protections, leading to higher levels of hazardous air pollution and accelerating climate-linked health impacts.

On February 12, 2026, the U.S. Environmental Protection Agency (EPA) announced its repeal of the 2009 Endangerment Finding... This comes as the latest move by the Trump Administration in its deregulatory agenda.

Last week, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced the single largest deregulatory action in American history. ATR applauds this historic action, which will save Americans a whopping $1.3 trillion. Not only will this action result in an average cost savings of over $2,400 per vehicle, but it will also lower prices of all products by lowering the cost of trucks.

In addition, EPA repealed greenhouse gas emissions standards for light-, medium-, and heavy-duty vehicles. This new rule overturns the agency’s own scientific finding established after years of scientific and economic analysis.

EPA leadership stated that removing the related rules will lower vehicle costs, reduce regulatory burdens, and allow consumers more freedom to choose the vehicles that best meet their needs.

Donald J. Trump’s Environmental Protection Agency prioritized environmental deregulatory actions in 2025 and plans more of the same for this year. One EPA priority is continuing action to rescind the key scientific finding behind US climate rules.

EPA regulatory impact analyses often project cost savings from rollbacks, but such figures are typically based on agency models and contested by environmental groups as underestimating health and climate costs; the $1.3 trillion figure aligns with Trump-era deregulatory claims but lacks independent verification in early 2026 reporting.

The EPA has reversed its position on whether or not it can regulate greenhouse gas emissions, eliminating influential rules that were put in place during the Obama administration.
