Escalating Legal Attacks on California’s Longstanding Clean Air Act “Waiver” Authority

This past week, the U.S. Supreme Court issued important orders in two closely-related environmental cases previously decided by the U.S. Court of Appeals for the District of Columbia.  Last Friday the justices granted review in Diamond Alternative Energy v. Environmental Protection Agency, agreeing to decide whether fossil fuel manufacturers have legal standing to challenge an …

EPA Grants California’s Waivers for Clean Cars and Clean Trucks

By finally granting the Advanced Clean Car II waiver, the agency just undercut Trump’s planned attack on electric vehicles.

EPA just made the incoming Trump Administration’s efforts to stop the move toward clean, zero emission vehicles a whole lot tougher.  And ironically, the U.S. Supreme Court’s controversial decision overturning deference to agency actions, Loper Bright v Raimondo, may help California in any litigation over the legitimacy of the waiver request. EPA finally granted California …

Contrary to myth, Congress has actually passed laws relating directly to climate change.

It’s a common misconception that Congress has never passed any climate change legislation. But Congresshas passed at least laws regulating two powerful greenhouse gases, as well as a series of other laws stretching back almost forty years. The story begins under President Nixon and extends into the Biden years with the multi-billion dollar Inflation Reduction Act.

Will It Be Environmental Law & Policy Deja Vu All Over Again? Or Even Worse?

Californians who care about the environment likely–and justifiably–feel whipsawed this week.  Former President Trump (#45) has re-emerged as President-elect Trump (#47), interrupted by the intervening four years of the Biden-Harris presidential administration.  (Actually, this presidential whipsaw has been going on for decades: think Bush Sr.-Clinton-Bush Jr.-Obama-Trump-Biden-Trump redux.) In general, California’s progressive environmental laws and policies …

Six Sleeper Proposals in Project 2025

Project 2025 isn’t just its headline proposals. It’s a thorough, detailed attack on environmental protection.

Project 2025’s proposals involve reduced protection for endangered species, eliminating energy efficiency rules, blocking new transmission lines, changing electricity regulation to favor fossil fuels, weakening air pollution rules, and encouraging sale of gas guzzlers. There’s some pious talk about protecting the environment, but every proposal calls for weakening environmental protections.

The Election, Vehicle Emissions, and State Climate Plans

If the California car waiver survives a possible Trump presidency, we may have the overruling of Chevron to thank.

If one single thing about the election keeps state environmental regulators up at night, it’s how much a Trump victory would impact their ability to cut transportation emissions. As it turns out, Trump’s leverage would be reduced, ironically enough, because his conservative Supreme Court appointees  helped overrule the Chevron doctrine.  Trump can still cause a …

Climate Policy After the 2024 Election

In this UCLA Emmett Institute webinar, panelists discussed the climate implications of the 2024 election from the state, national, and international perspective.

The Supreme Court & Interstate Pollution

It was puzzling that the Court agreed to hear the case. How has it ruled? And why?

Months ago, the Supreme Court agreed to hear an “emergency” request to stay EPA’s new rule regulating interstate air pollution.  Like most observers, I was puzzled that the Court was bothering with the case before the D.C. Circuit even had a chance to consider the merits of the challenges. Months later, the Court has finally …

Some of the choices may surprise you.

What are America’s most important environmental laws? Some are familiar, such as the federal air and water pollution laws, and the Endangered Species Act. But there are other people rarely hear about — even in environmental law courses — but have done a lot to protect the environment.

EPA’s New Power Plant Rules Have Dropped. What Happens Next?

Media battles. Lawsuits. Stay requests. And political mayhem.

The release of Biden’s new climate regulations for power plants will unleash a maelstrom of legal and political battles. One key question: Will the Supreme Court short circuit the litigation process by staying the rules.
