Why It Matters
Removing the endangerment finding dismantles the primary legal basis for U.S. carbon regulations, exposing the economy to higher climate risk and opening the door to extensive litigation.
Key Takeaways
- •EPA to revoke 2009 greenhouse gas endangerment finding
- •Revocation threatens vehicle and power plant emission standards
- •Legal challenge likely under Massachusetts v. EPA precedent
- •Could expose automakers to new climate lawsuits
- •Sierra Club vows litigation to protect climate regulations
Pulse Analysis
The EPA’s 2009 endangerment finding was the cornerstone of federal climate regulation, translating decades of scientific consensus into enforceable limits on carbon‑intensive sources. By rescinding that finding, the Trump administration is not merely adjusting a rule; it is redefining the nation’s stance on climate science and signaling a retreat from the Clean Air Act’s authority to curb greenhouse gases. This reversal overturns a decision upheld by federal courts and contradicts the agency’s long‑standing mandate, raising immediate questions about the future of vehicle fuel‑efficiency standards and power‑plant emissions caps.
The legal ramifications are immediate. The Supreme Court’s 2007 Massachusetts v. EPA ruling affirmed that greenhouse gases are pollutants subject to the Clean Air Act, providing the judicial foundation for the 2009 finding. Environmental litigants, spearheaded by the Sierra Club, are poised to invoke that precedent, arguing that the rollback exceeds the administration’s statutory authority. If courts block the repeal, automakers and fossil‑fuel firms could face renewed compliance costs; if the repeal stands, the regulatory vacuum may invite a wave of state‑level actions and private lawsuits seeking damages for climate harms.
Beyond the courtroom, the policy shift reverberates through capital markets and corporate strategy. Investors increasingly price climate risk, and a federal retreat could accelerate the shift toward state‑driven carbon pricing, renewable‑energy incentives, and ESG disclosures. Companies reliant on fossil‑fuel inputs may experience short‑term cost relief, yet long‑term exposure to litigation and reputational damage could rise. Politically, the move deepens the partisan divide over environmental regulation, underscoring the importance of upcoming elections for the direction of U.S. climate policy and the stability of related industries.
Trump Admin To Make Climate Denialism US National Policy
Continuing the theme of complete idiocy and mass human harm, the Donald Trump administration is on the verge of making climate change denialism US national policy. Why? Because we are apparently a petrolstate being run by a mixture of Homer Simpson and Mr. Burns.
Steve Hanley will write a much longer piece diving into this topic soon, but with the news out today, here are some initial statements on the anti‑science, braindead policy shift from the Sierra Club:
“Today, in a brazen assault on the health and welfare of the American public, the Trump administration announced that it will finalize its rule revoking the Environmental Protection Agency’s longstanding greenhouse gas endangerment finding under the federal Clean Air Act. With the stroke of a pen at a White House event this Thursday, EPA Administrator Lee Zeldin will formalize climate denialism as official government policy and move to eliminate EPA’s ability to directly fight the climate crisis.
“The 2009 finding—based on the overwhelming scientific evidence that carbon dioxide, methane, and other greenhouse gases endanger our health, our economy, and our future by driving global climate change—has been upheld unanimously in federal court. The finding gives EPA the formal statutory authority and obligation to regulate emissions of these heat‑trapping gases from motor vehicles—the largest source of climate pollution in the United States—and laid the ground for control of greenhouse gas emissions from other major sources like power plants. It was adopted following a rigorous rulemaking process considering thousands of public comments and a massive record of scientific research, which has grown far more voluminous in the intervening years.
“Lee Zeldin and Donald Trump plan to toss out the endangerment finding on blatantly specious legal grounds, attempting to wish away the Supreme Court’s landmark 2007 holding in Massachusetts v. EPA that the Clean Air Act does cover greenhouse gas pollution. While this rule specifically concerns greenhouse gas emissions from vehicles, EPA has made clear that it will do the same for other major sources of climate pollution like power plants.
“Sierra Club has been involved in the legal fight for federal climate standards longer than any other organization. In December 2002, the Club filed the first climate case under the Clean Air Act in federal court, seeking to force EPA to limit greenhouse gas emissions from vehicles under the statute. That lawsuit ultimately led to the Court’s holding in Massachusetts and the agency’s issuance of the endangerment finding in 2009. Now, two‑and‑a‑half decades later, Trump and Zeldin are trying to destroy these hard‑fought victories and turn back the clock to the 19th century.
“Eliminating federal greenhouse standards will not only imperil the public, but could also open the floodgates to litigation directly against automobile manufacturers, fossil fuel companies, and other major sources of greenhouse gases who were otherwise shielded from such lawsuits under a 2011 Supreme Court ruling.
“In the wake of this week’s announcement, the Sierra Club and partners are exploring all legal options in response, including litigation.”
Let’s hope the legal efforts can get somewhere … but, really, there’s only one solution to this overall problem. Donald Trump and Republicans need to be booted from the White House.
“It appears that the Trump administration will make it their official policy that our lives, our health, and our future are of no importance to them, only polluter profits. Climate change is wreaking havoc right now, destroying communities and endangering our lives. Instead of fighting it, Donald Trump is instead just focused on helping corporate polluters profit,” Sierra Club Executive Director Loren Blackford summarizes. “Removing EPA’s authority to limit deadly greenhouse gas emissions is as shortsighted as it is reckless. Communities will suffer as extreme weather continues to threaten us all, costs will continue to rise, and we will saddle future generations with a world that grows increasingly unlivable and endangers the life we know. Donald Trump is abandoning his job to help the American people, and we will do everything in our power to block this misguided effort that puts polluters before people.”
