UCS Climate & Accountability Campaigns

Today, Administrator Zeldin took a chainsaw to the Endangerment Finding, undoing this long-standing, science-based finding on bogus grounds at the expense of our health.

Statement by Julie McNamara, associate policy director of the Climate and Energy Program at the Union of Concerned Scientists (UCS)" “Reality doesn’t lie: coal is a rapidly dwindling relic of the past, not a solution for the future. "

Today, the Trump administration announced a series of initiatives attempting to prop up struggling coal-fired power plants.

🛢️Why are fossil fuel companies so threatened by offshore wind?

@ucs.org Senior Energy Analyst Susan Muller explains how powerful interests are using disinformation to slow clean energy progress and why we can’t let them.

Write to your members of Congress TODAY and tell them: No Immunity for Big Oil!

House Member Crafting Legislation to Stop Climate Lawsuits Against Big Oil | Center for Climate Integrity Following Reports the Oil Industry is Lobbying for Total Immunity from Climate Lawsuits, Harriet Hageman (R-WY) told A.G. Bondi that She Is Working on A Bill

As communities move closer to putting Big Oil companies on trial to make them pay for the damage their climate lies have caused, the fossil fuel industry is panicking and pleading with Congress for a get-out-of-jail-free card.

Let’s be clear: you don’t need immunity unless you are responsible.

🚨 A U.S. House representative said she is crafting legislation to stop climate lawsuits and climate superfund laws that would make Big Oil companies pay for climate damages.

It’s time for leaders in Congress to speak out and make clear that Big Oil is not above the law.

Trump Administration to Cut Common-Sense Flood Rule that Saves Homes, Lives and Taxpayer Dollars Repealing the standard endangers the most vulnerable among us.

The impact of this repeal will be felt disproportionately, harming low-income residents, people of color, the elderly, and those with disabilities.

Trump Administration to Cut Common-Sense Flood Rule that Saves Homes, Lives and Taxpayer Dollars Repealing the standard endangers the most vulnerable among us.

It ensured HUD’s federally funded projects would be built to withstand current and future #flood risk. This means new buildings, facilities and homes, and substantially damaged improvements to them will be at an increased risk from #SeaLevelRise and severe weather super-charged by #ClimateChange.

Trump Administration to Cut Common-Sense Flood Rule that Saves Homes, Lives and Taxpayer Dollars Repealing the standard endangers the most vulnerable among us.

"The Trump administration is set to repeal the US Department of Housing and Urban Development’s (HUD) rule establishing requirements on implementing the Federal Flood Risk Management Standard (FFRMS) which went into force May of 2024."

Trump to repeal Obama-era finding foundational to US climate rules Climate groups vow to fight rollback of 2009 finding determining CO2 and other greenhouse gases harm health

“The science establishing harm to human health and the environment from global warming emissions was evident in 2009 and it’s even more undeniable today,” said UCS President & CEO @gretchentg.bsky.social to @theguardian.com regarding the Trump admin’s rollback of the endangerment finding.

Thank you @davids.house.gov for pushing back on attacks on federal fuel economy standards. These rules save drivers thousands, cut pollution, and strengthen U.S. energy security. #CleanerCars #RouteZero

These US states want polluters to pay for the rising insurance costs of climate disasters Proposals by California, Hawaii and New York lawmakers aim to hold fossil fuel industry accountable for soaring rates

People can’t afford home insurance, and Big Oil is to blame.

"States need every tool available to protect their residents, including the ability to make the big oil corporations most responsible for this mess pay their fair share of the rising costs," said CCI's @iylas.bsky.social.

Minnesota moves closer to putting Exxon, Koch, and American Petroleum Institute on trial | Center for Climate Integrity A three judge panel rejected Big Oil’s latest arguments for escaping the state’s climate and consumer fraud lawsuit.

Minnesota is one step closer to putting ExxonMobil, Koch Industries, and the American Petroleum Institute on trial for climate and consumer fraud. 🙌

"These defendants prioritized their profits over the people of Minnesota, and deception was their business model,” said @ag.state.mn.us last year.

Climate Change Is Erased From a Manual for Federal Judges

Dr. Delta Merner is quoted, noting that the end of the Chevron deference means that judges “must more carefully assess scientific evidence when interpreting the law. That elevates the importance of clear, well-supported science in the courtroom and robust standards for evaluating expert testimony.”

Big Oil Has Been Lying to Us for Decades: Don’t Let It off the Hook As people and communities seek accountability, the industry is pleading for an escape hatch.

Consensus about the causes & threats of climate change is nearly universal in the scientific community after decades of research. Judges should have access to this information. We can't keep letting the deep-pocketed, destructive, deceptive fossil fuel industry override the public interest.

Who Wrote the Trump Administration’s Flawed Climate Report? Meet the Architects of Disinformation Industry-backed actors create the illusion of legitimate debate, exploit uncertainty, and delay action.

Meanwhile, it’s telling that the critics of the climate science chapter referenced a recent Dept of Energy report that was conducted in secret by five known climate contrarians with ties to the fossil fuel industry. This report has been thoroughly debunked by dozens of scientists.

"Withholding climate science from judicial education does not protect neutrality; it weakens the court’s ability to fairly evaluate facts in cases that increasingly reflect the real-world impacts of climate change on people and the economy, while potentially favoring polluters.”

What to Watch in Climate Litigation in 2026 The year ahead will be a test of climate accountability.

"Courts around the world are already grappling with nearly 3,000 climate-related cases, many of which hinge on robust scientific evidence about causation, risk, and harm. Judges need access to the best available science to understand the evidence before them and make informed decisions.”

Quote from our @ucs.org colleague Dr. Delta Merner: “The decision to remove climate science from a judicial reference manual is deeply concerning and fundamentally misguided.”

Climate science removed from judicial manual after GOP complaints Republican attorneys general argued the new chapter would put judges “firmly on one side” of climate lawsuits against the fossil fuel industry.

More disturbing news today about the removal of scientific evidence from decision-making processes in our federal government. Censoring educational materials about the climate crisis will not make it go away - it will just make our public institutions less equipped to deal with it.

Huge. Laws like this were designed to punish investors for taking basic steps to address climate risk.

(Also worth noting: the firms targeted were never actually “boycotting” fossil fuels—that was political misinformation all along.)

Authors Sam Gomberg and Rachel Licker were guests on the #CleanPowerHourPodcast to talk about how we're planning for yesterday's climate while tomorrow's storms are already here. The result? Billions in damage, lives lost, and communities left powerless when they need electricity most.

“Someone has to pay — and it will be us, if Big Oil gets immunity,” said Shemona Moreno of @350seattle.bsky.social.

Big Oil knowingly fueling the climate crisis, and communities are paying the price.

Congress must protect our right to hold polluting corporations accountable.
