EPA Administrator Zeldin is using the proposed Endangerment Finding repeal to suggest rolling back rules that limit vehicle pollution. This would mean dirtier air in our communities and higher fuel costs for drivers.
Trump’s EPA is throwing out a major tool that allows it to regulate harmful and costly pollution. The EPA Endangerment Finding repeal will make our air dirtier, our lives more expensive, and our planet less healthy. EPA Administrator Lee Zeldin and President Trump are behind this effort to enrich Big Polluters at our expense. Here’s what you need to know.
EPA’s 2009 Endangerment Finding shows greenhouse gas emissions are bad for public health based on decades of scientific evidence. Since it was enacted, it has provided legal and scientific support for rules that limit air pollution – specifically greenhouse gases – under the 1970 Clean Air Act.
By rescinding the Endangerment Finding, the Trump administration has effectively said they don’t believe greenhouse gas emissions and climate change don’t harm human health. But they do. Repealing it is all a part of their plan to give polluters free rein to dump as much pollution into our air and water as they want.
At its core, repealing the Endangerment Finding is a giveaway to polluting industries and extreme climate deniers. The oil and gas industries’ ultimate goal is to maximize profits. EPA is supposed to make sure they don’t harm our communities and environment in the process. Lee Zeldin and Donald Trump are giving these industries a free pass to pollute as much as they want and ignore their impact on our health and the price we pay for energy.
This action fits into the administration’s larger plan to get rid of health and safety guidelines to benefit Big Polluters. It is the latest in a slew of anti-environmental, pro-polluter actions coming out of the Trump administration, including:
Setting the value of human life at $0. EPA announced it will ignore the monetary value of human lives saved, heart attacks and strokes prevented, asthma averted, and other health effects when setting air pollution limits. This aims to keep the public in the dark about the impacts of climate pollution on their health.
Eliminating EPA’s Office of Research and Development to shut down independent science that could make it harder to give handouts to Big Polluters… and try to fool the public.
Forcing out career staff who have spent decades working to protect clean air and water.
Implementing processes intended to kill solar and wind projects. These projects could help lower energy costs for us all, but Trump’s cronies are working overtime to stop them in order to benefit their fossil fuel donors.
Dismantling EPA’s environmental justice office, removing the agency’s ability to support communities that have been particularly hard-hit by the climate crisis.
Repealing the Endangerment Finding would have major impacts for all of us, including:
More frequent and severe disasters fueled by climate change, such as wildfires, hurricanes, tornadoes, and floods. Rebuilding from climate disasters is expensive, so more disasters would also mean increased costs.
Greater health issues, including higher rates of cancer, asthma and more. Just as Republicans in Congress defund healthcare programs, rising pollution will make us sicker and drive up our medical costs.
Higher energy costs as Republicans ban clean, affordable energy choices and force us back toward polluting costly fossil fuels – particularly outdated and obsolete coal.
Yes. Because of the repeal, EPA Administrator Zeldin was able to eliminate rules that limit pollution from cars, SUVs, and pickups. This would remove the requirement that automakers reduce tailpipe pollution, which they often do by making more fuel-efficient cars. That means the cost of driving would go up, as we’d need to buy more gas, more often. It also means vehicles would spew out more pollution, making our air dirtier and worsening health conditions like asthma. Rolling back vehicle pollution standards would disproportionately harm Black, Brown, and low-income communities who tend to live closer to highways.
The Endangerment Finding repeal is Donald Trump and Lee Zeldin’s core strike against climate protections. They’ve already proposed going after greenhouse gas emissions standards from power plants. Unfortunately, we know there is more to come.
Lee Zeldin and Trump have repealed the Endangerment Finding, so that’s it, right? Not quite.
Thanks to decades of science and court rulings supporting it, getting rid of the Endangerment Finding isn’t that simple.
In 2007, the Supreme Court ruled that EPA has the authority and responsibility to regulate greenhouse gas emissions under the Clean Air Act. In 2012, this ruling was upheld by the D.C. Circuit Court. In the years since, the negative impacts of greenhouse gas pollution on our health have become more and more obvious.
But MAGA Justices dominate the Supreme Court and Trump is quickly appointing more political extremists to federal judicial positions. Sadly, it’s fair to question whether these judges are more concerned with supporting President Trump’s agenda than following the laws and Constitution. And Trump himself has flat-out ignored the law and many court rulings that aren’t favorable to his agenda.
While the Endangerment Finding is on solid legal and scientific footing, that doesn’t mean much to an administration known to flout both the law and science. However, there are likely to be multiple lawsuits challenging the reversal.
We must work to hold Trump and Zeldin accountable for this blatant denial of climate science and the harm it will cause for our communities and climate. Contact your member of Congress today to urge them to hold President Trump and EPA administrator Zeldin accountable for repealing the Endangerment Finding.

Act Now
President Trump and EPA Administrator Zeldin have repealed the endangerment finding, one of the most important foundations for federal protections for our public health and the environment. This repeal gives Trump's Big Oil & Gas donors a free pass to pollute the air we breathe, so they'll get richer while everyday people get sicker. Tell Congress: Hold Trump and Zeldin accountable — we need an EPA that protects people, not corporate polluters!
