In January, the U.S. Supreme Court heard oral arguments in a pair of related cases — Loper Bright Enterprises v. Raimondo and Relentless v. Department of Commerce — which could be among the most consequential decisions for U.S. democracy that the Court has ever issued. That’s because the cases urge the Court to overturn a longstanding judicial doctrine called Chevron deference. Over the last 40 years, that doctrine has provided a practical framework for mediating the growing separation-of-powers fights among the three branches for control over administrative agencies, with the preservation of the administrative state’s essential democratic foundation as its guiding star.

How should the United States manage the largest biodiversity conservation system to be greater than the sum of its parts? This vexing question for the national wildlife refuges has received scant attention for the past quarter century. Now the U.S. Fish & Wildlife Service (Service), which administers the refuge system, has proposed a rule to guide specific refuge decisions to ensure they contribute to a national network rather than incrementally fray the web of conservation.

A profound energy transition is sweeping the United States. In addition to mitigating dangerous greenhouse gas emissions that contribute to climate change, it means new economic opportunities and a safer and healthier environment for communities across the country. A better future is certainly within reach, or at least it is for some communities, which are the ones that will be able to capitalize on the green transition. But for many others, there is no guarantee that this clean energy transition will be a just and equitable one. Why is this the case? As we explore in a new report and interactive map, it turns out that one of the biggest obstacles is self-inflicted: local ordinances that restrict new renewable energy development projects, including wind, solar, and battery storage.

On February 7, the U.S. Environmental Protection Agency (EPA) finalized new and stronger air quality standards for fine particle pollution (commonly known as soot), a harmful pollutant and byproduct of burning coal, manufacturing, oil refining, and motor vehicles. Soot is one of the nation’s most dangerous air pollutants, and one of the most widespread, though it disproportionately impacts the health of structurally marginalized communities. Multiple reports have found that people living within half a mile of warehouses have higher rates of asthma and heart attacks than residents in the area overall, increased risk of cancer, and nervous system effects.

As North Carolinians continue to grapple with rolling blackouts and rising energy bills, yet another pending environmental catastrophe is developing in our backyards. Duke Energy, our state’s monopoly utility provider, has submitted filings for two new methane gas power plants — one at the current Roxboro coal plant in Person County and another at the Marshall plant on Lake Norman.

EPA has just issued a rule tightening the air quality standard for PM2.5 — the tiny particles most dangerous to health — from an annual average of 12 micrograms per cubic meter down to 9 micrograms per cubic meter. EPA estimates that, by the time the rule goes into effect in 2032, it will avoid 4,500 premature deaths, 800,000 asthma attacks, and 290,000 lost workdays. Most likely, by the time this post goes up, someone will have filed a lawsuit to overturn the EPA rule. What legal arguments will challengers raise, and what are their chances of winning? Let’s consider the possible challenges one by one.

In 2023, the Supreme Court ended 50 years of broad federal protection of wetlands in Sackett v. United States. It is only when you look back at the history of federal wetlands regulation that you realize just how radical and destructive this decision was.

Later this month, the U.S. Supreme Court will hear oral argument about whether to stay a plan issued by the U.S. Environmental Protection Agency (EPA) to limit upwind states from creating ozone pollution that impacts other states. As I wrote before the Court decided to hear the arguments, the issues here seem less than earthshaking, and for that matter, less than urgent. It was puzzling to me why after many weeks, the Court was still sitting on the “emergency” requests of the upwind states to be rescued from the EPA plan. Given that the Court seems to think the issues are important enough to justify oral argument, however, it’s worth examining what seems to be bothering the Court about implementing the EPA plan.

I find the Center for Progressive Reform’s pursuit of environmental justice inherently appealing, but this work raises provocative questions: Should U.S.-focused groups like the Center and policymakers pursue an environmental justice mission that does not account for potentially negative trade-offs in developing countries? Or, are there ways to account for those trade-offs to ensure environmental justice work and efforts to address climate change benefit people across the globe?
