Some Good News About the El Segundo Chevron Explosion

The Drain is a weekly roundup of environmental and climate news from Legal Planet.

When the state’s second-largest refinery emitted a fireball into the heavens last week, it was bad. But it wasn’t all bad. The “incident” at the Chevron refinery in El Segundo was a good reminder that air pollution is present during the entire life cycle of oil and gas products, from when it comes out of …

Webinar: Climate Policy without the Endangerment Finding

UCLA Law’s “Up in the Air” webinar explores the future of federal and state climate policy if the endangerment finding is repealed.

As Environmental Protection Agency Administrator Lee Zeldin rushes to rescind the endangerment finding — which some have called “the Holy Grail of U.S. climate policy” — the UCLA Emmett Institute hosted an expert panel discussion on the reasoning and ramifications of such a move.  The effort underlines “an extraordinarily dark time in U.S. environmental politics,” …

New CARB Chair, New CARB Mandate

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, …

Why are California’s Zero-Emission Truck Standards Under Attack?

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 …

Can California Try Again with Vehicle Pollution Limits?

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.

Watch “Clearing the Air: The War on Smog”

LAPL

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 Woeful Economics of a Misguided Rollback

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.

What Do Bureaucrats Maximize?

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 …

How Methane Satellites Work and Why it Matters

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 …
