Clean Air Act

Cars, Smog, and EPA

Over the past fifty years, EPA has overseen incredible reductions in auto pollution.

This is part of an occasional series of posts about the evolution of pollution standards. Today’s subject is pollution control for new vehicles, which have been known to cause smog since the 1960s. The history of these pollution standards is quite distinctive. At the high temperatures in internal combustion engines, some of the nitrogen in …

State Air Regulations Can Go Above and Beyond National Standards

State and local regulators can and should work to reduce particulate matter, ozone, and NOx emissions even when national standards are met.

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards (NAAQS) set by the U.S. Environmental Protection Agency (EPA) under the federal Clean Air …

The Utility Response to EPA’s Climate Rules

The power industry apparently shares some progressive doubts about CCS and hydrogen

There are three big takeaways from the utility industry’s comments on EPA’s proposed new climate rules. First, the industry seems to share progressive concerns about whether we can count on hydrogen and CCS (carbon capture and sequestration). Second, the industry doesn’t invoke the major question doctrine, making it clear that it does not view such …

Biden’s Proposed Power Plant Rule is a Solid First Step

The electric power sector remains 30 percent of the nation’s carbon dioxide emissions, and this rule can incentivize the push towards renewables.

On May 23, the Environmental Protection Agency (“EPA”) proposed emission limits and guidelines for carbon dioxide from fossil fuel-powered plants. To avoid the same fate as the Obama Administration’s Clean Power Plan, which was struck down by the conservative Supreme Court in West Virginia v. EPA last year, the new draft rule does not determine …

EPA and the Student Loan Decision

Will the major questions doctrine block EPA’s proposed rules?

Biden v. Nebraska, the student loan case, provided a new opportunity for the Court to apply the major question doctrine. Does this decision increase the threat that EPA’s proposed new regulations will be struck down under this doctrine? A careful reading of the majority opinion is at least somewhat reassuring. The Court painted a picture …

EPA’s Power Plant Rule is Not Bold. It’s What’s Required.

It’s important to remember the regulatory history—and the growing urgency—of limiting climate change-related carbon pollution from power plants. 

Today’s the day for the long-awaited release of Environmental Protection Agency regulations to tackle planet-warming pollution by the nation’s power plants. (Read the announcement here and the full text here.) The EPA is proposing a new standard for fossil fuel-fired power plants to avoid 617 million metric tons of carbon dioxide through 2042. For weeks, …

The Car Rule and the Major Questions Doctrine

Claims that the new rule violates the doctrine are groundless.

Ever since the Supreme Court decided West Virginia v. EPA, conservatives and industry interests have claimed that just about every new regulation violates the major question doctrine. When the Biden Administration ramped up fuel efficiency requirements through 2026, ideologues such as the Heartland Institute and states like Texas were quick to wheel out this attack. …

U.S. Climate Law: A Broad & Rapidly Growing Field

There’s a lot of law relating to climate change. A lot!

In preparing to teach a course on climate law, I was really struck by how broad and rich the field has become. Back in the day, it was nearly all international law, but nowadays there’s a huge amount of U.S. domestic law. Most people, even those who work on the field, tend to focus on …

Do Climate Change Cases Belong in Federal Court? The Biden Administration Weighs In.

In a very narrowly argued brief, the Administration calls for returning the cases to state court.

The Biden Administration, at the Supreme Court’s invitation, has now filed a brief giving its views about current lawsuits against oil companies. The gist of the brief is that the cases belong in state court., and that the Court should let that happen rather than stepping into the litigation. The brief is right about that, …

“Major Questions” for Texas (and for the Environment)

Defending clean car regulations and tracking judicial decision-making

Last June, the Supreme Court formally unveiled the “major questions” doctrine in the landmark environmental case West Virginia v. EPA. In rejecting EPA’s plan to regulate greenhouse gas emissions from existing power plants under Section 111(d) of the Clean Air Act, the Court stated that “agency decisions of vast economic and political significance” (i.e., those …

Can We Use Regulation to Reduce Inequality?

Contrary to some, I think the answer is yes. And here’s how we can do it.

An Important Groundwater Bill Lands on the Governor’s Desk

Guest Contributors Gabi Rosenfeld, Owen McAleer, and Adrianne Davies say AB 779, a bill they worked on with State Assemblymember Lori Wilson, will address inequities in groundwater adjudications.

The Overshoot Commission Addresses Geoengineering

The Commission tries to make it OK to talk about – not do – solar geoengineering. Its report proposes a moratorium, coupled with efforts to carefully build knowledge.

What’s a Major Question? Opinions differ.

Scholars don’t know the answer. Nor, apparently, do the federal courts of appeals.

No, There’s No Scientific Conspiracy About Climate Change

Anyone who thinks otherwise has never met a real live academic. We can barely conspire about where to eat lunch.
