Opinion | The Supreme Court May Rein In Efforts to Protect the Climate

If you continue to harbor doubts that the Supreme Court’s conservatives are advancing an ideological agenda, the next few weeks will probably lay those to rest.

Before breaking for the summer at the end of this month, the court is likely not only to strike down or severely curtail the constitutional right to an abortion and expand gun rights but also to undermine important environmental protections.

From my perspective as an environmental lawyer and a former clerk for Justice Sandra Day O’Connor, a case that looms large is West Virginia v. Environmental Protection Agency, which should be decided within weeks. The justices will determine how much authority the E.P.A. has to address the climate crisis by regulating emissions of climate-warming carbon dioxide from power plants.

The Obama-era regulation at issue never went into effect because the Supreme Court’s conservatives suspended the rule. And it never will go into effect because the Biden administration is in the process of proposing a new rule. So there is no dispute to resolve yet, and thus no “case or controversy” that would support the court’s jurisdiction.

Why is the court going beyond calling balls and strikes, as Chief Justice John Roberts memorably described his role, to take a case it arguably doesn’t have jurisdiction to hear? Some of the court’s conservatives seem eager to assist polluting industries by undercutting the power of agencies to regulate in the public interest. More specifically, certain justices have signaled their interest in sharply limiting the E.P.A.’s authority to regulate greenhouse gas emissions in the West Virginia case by invoking and expanding a “major questions” doctrine. That doctrine invites unelected judges to second-guess Congress when lawmakers give an agency the authority to regulate on matters that have “major” political or economic significance.

Agencies need latitude to regulate in a world of novel problems and scientific complexity. Congress routinely gives them expansive authority through broadly-worded statutes. And Congress puts its own limits on agency discretion. Laws like the Administrative Procedure Act require that agency actions be consistent with science and informed by public input. Further, Congress has ample tools to get a wayward agency back on track: confirmation and oversight hearings, budget instructions, or even statutory amendments if necessary.

Expanding the major questions doctrine would destabilize this legislative balance and shift power to the courts. The doctrine would leave agencies with little power to tackle new and pressing environmental problems like climate change without a steady stream of statutory instructions at a degree of detail that an inexpert and political entity like Congress is unequipped to provide. Worse, the doctrine is uncertain and manipulable. Even conservative justices struggle to define what triggers a “major question” review. Virtually any environmental regulation worth issuing has “major” impacts on some industry, so the doctrine invites polluters to challenge regulations and gives sympathetic judges a potent tool for striking them down.

The climate, and the world, are changing. What challenges will the future bring, and how should we respond to them?

Even more concerning, West Virginia v. E.P.A. may be only the beginning. In its next term, the Supreme Court will likely take up another important environmental case: Sackett v. E.P.A., which concerns the geographic reach of the Clean Water Act.

Once again, the court agreed to take up a case it would normally have declined: Appeals courts have consistently agreed on the scope of the statute relevant to the Sackett case, and the E.P.A. and the Army Corps of Engineers will likely soon finalize a new proposed rule to provide further clarity on how the law should work. So again, the court appears to be reaching out aggressively to hear a case that could advance a deregulatory policy agenda: restricting the scope of one of the country’s most important environmental laws, administered by an agency mandated to protect the public health and environment.

The Clean Water Act prevents polluters from dumping waste into the nation’s waters without a permit. Conservative groups and extractive industries want the court to hold that the law does not protect certain wetlands, which would benefit polluting industries to the detriment of downstream waters and people.

Americans are increasingly concerned about the environment, and two-thirds of us think our government should do more to protect it. Why then do the Supreme Court’s conservatives seem to be going so far out of their way to hamstring federal efforts to regulate polluters and slow climate change?

The reason is that the court’s five most conservative justices were seemingly selected primarily for their fidelity to an agenda that is so far outside the legal mainstream that even Charles Fried, President Ronald Reagan’s conservative solicitor general, called it “reactionary.” Moreover (and not coincidentally), they were confirmed by senators who together were elected with fewer votes than senators who opposed their confirmations. Three of them — Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett — were nominated by a president who lost the popular vote.

This profound disconnect between the will of the people and the court’s deregulatory agenda on the environment could not come at a more dangerous time. The Intergovernmental Panel on Climate Change warns that our window to avert irreversible climate harm is closing fast. If the Supreme Court chooses this moment to pursue an agenda of limiting federal regulatory power, it will serve the interests of corporations — particularly fossil fuel companies — while pushing people and the planet closer and closer to the point of no return.
