California and Brazil Advance Joint Climate Action
The new MOU announced at New York Climate Week increased engagement and joint climate leadership ahead of COP30.
This week, California Governor Gavin Newsom led a high-level meeting with Brazil’s Environment Secretary Marina Silva to expand the long-running partnerships that exist between the Golden State and the largest country of Latin America. The meeting resulted in a new Memorandum of Understanding (MOU) between both governments to continue to collaborate on climate action. Although …

Lauren Sanchez has been named to the state’s most important climate job.
About 15 years ago, when presenting about California’s then-new climate change law AB32, I used to show a slide with six words on it — “Why Mary Nichols Rules the World”— along with a huge photo of Mary. The slide let me talk about the enormous authority and discretion bestowed by AB32 on one agency, …

They are highly effective, as CLEE’s new Factsheet series on Zero-Emission Trucks documents.
The world of zero-emission trucks is at a pivotal moment. On one hand, the technology is rapidly advancing, and manufacturers are producing a growing number of zero-emission truck models in Europe, China, and here in California. Yet on the other hand, this clean transition is facing significant political and legal challenges from the U.S. federal …

A new Sixth Circuit decision provides encouragement.
In May, Congress effectively killed the most recent efforts by California to clean up its vehicle fleet. Although many people seem to have assumed the contrary, this may not be the end of the road for California regulators. A new court of appeals decision is an encouraging signal that California may be able try again when the political forces in DC are less militantly anti-environmental.

The American Experience’s “Clearing the Air: The War on Smog” tells an extraordinary story. It premieres on PBS this Tuesday.
A few years back, a colleague of mine, who I very much wanted to remain at UCLA, approached me because he was contemplating accepting an offer at a Washington, D.C. law school. He feared remaining in Los Angeles, even though he wanted to stay, because he didn’t want his young daughter exposed to the southland’s …

The costs of Trump’s rollback of key climate rules far outweigh any benefits.
Trump’s rollback of regulations limiting emissions from power plants is an economic disaster. According to economists, health damages far exceed savings from lower compliance costs. Just considering health impacts alone, the net cost of the rollback will be $129 billion through 2050. Climate damages add another $148 billion in costs.

New research demonstrates that governments can reduce intractable emissions problems — if they have the right incentives
It’s no secret that Delhi has perhaps the worst air quality in the world, and it’s also no secret that crop-burning in nearby agricultural areas is one of the principal causes (along with topography). But what can you do about it? It’s illegal already, but because crop-burning is a cheap and effective way to get rid …

This new UCLA Law report aims to help policymakers understand the science and utility of methane satellites.
These days, I’ll take progress on climate change where I can get it. And one place to look right now is up — literally. New satellites are providing never-before-seen data about global methane sources, helping policymakers, industry, and others target that superpollutant in new ways. Today, some colleagues at UCLA Law and I are releasing …

Avoiding a climate disaster isn’t something today’s students can plan on tackling “over the course of their careers.” The most critical time will be the next fifteen years, which means you’ll need to get to work quickly.What we do together between now and 2035 will determine what your lives look like in 2050 and 2080, and what your children and grandchildren will see in the next century. So grab your books, get yourselves ready, and be prepared to head for the trenches when you graduate. No time to waste!

AI is fueling a surge in data center construction. Here’s what you need to know.
Data Centers have significant environmental footprints, which is going to raise several permitting issues except for those using clean energy sources. The permitting issue are mapped out in this post. The Trump Administration is clearly going to do its best to free the industry from environmental limits. We’ll see how successful that is going to be.
