It’s Time to Repeal the Clean Power Plan
The CPP no longer serves any useful purpose, and keeping it on the books invites mischief by the Supreme Court.
The Clean Power Plan (CPP) was the Obama Administration’s signature climate effort. This 2015 regulation aimed to move state power grids away from coal and toward renewable energy. It immediately became ensnared in litigation and never went into effect. It’s now considered irrelevant for all practical purposes. Yet the Supreme Court is now set to …

They’re even worse than you probably thought.
The decision at the Glasgow climate conference to phase down fossil fuels is an important step forward — and not just because of climate change. We think of fossil fuels as a source of climate change, but that’s only a one part of the problem. From their extraction to their combustion, everything about them is …

A review of inventory, monitoring, and regulatory tools needed to reduce agricultural methane emissions
(This post was authored by Eric Peshkin, a JD candidate at NYU School of Law and CLEE summer research assistant) Last week, global leaders announced a commitment to reducing global methane emissions. In a previous blog post, I briefly reviewed some of the innovative strategies to reduce methane emissions from agricultural livestock and rice operations, …

Legislation Promotes New Housing, Infill Development, & Reduced Air Pollution
The California Legislature recently enacted, and Governor Gavin Newsom last week signed into law, two major housing reform measures. SB 9 and SB 10 represent California’s most transformative new housing laws in decades, and are a belated but welcome legislative response to the state’s longstanding housing crisis. SB 9, authored by California State Senate leader …

If we “beat” climate change, what will we have to show for it?
Suppose we bring climate change under control and deal with its fallout. What will have we achieved? We will have prevented great harm. That, of course, is the main goal. Untamed climate change means an dangerous, ugly future for all of us on “Spaceship Earth.” Preventing that future is surely enough of a reason to …

An opinion piece in the NY Times reveals a disconnect between history and what we expect from wildfires and air quality
There’s a lot of news coverage about the wildfires on the West Coast right now, and rightly so. But with that news coverage comes a lot of commentary, some of which might lead us down the wrong policy path. I want to highlight an example from the New York Times opinion page, not because it …

CONTINUE READINGWhy I Was Wrong About Methane
I didn’t think cutting methane was a high priority. Now I do. Here’s why.
I didn’t use to think that eliminating methane emissions should be a priority. True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. In contrast, CO2 emissions cause warming for 2-3 centuries or more. So methane emissions seemed to be something …

CONTINUE READINGCost-Benefit Analysis and the Biden EPA
The recent rescission of a Trump rule hints at how the Biden Administration views the role of cost-benefit analysis.
In its closing days, the Trump Administration issued a rule designed to tilt EPA’s cost-benefit analysis of air pollution regulations in favor of industry. Last week, EPA rescinded the rule. The rescission was no surprise, given that the criticisms of the Trump rule by economists as well as environmentalists. EPA’s explanation for the rescission was …

With a clever if contrived argument, the Second Circuit tries to eliminate climate change litigation.
On Friday, the Second Circuit issued an important decision in a lawsuit against the oil industry. New York City had sued the oil companies for harms relating to climate change. The appeals court ordered the case dismissed, on the ground that any harm relating to fossil fuel is exclusively regulated by the Clean Air Act. …

It’s not that the policy choices are that hard. It’s the 6-3 Supreme Court.
Coal- and gas-fired power plants are a major source of U.S. carbon emissions. The Obama Administration devised a perfectly sensible, moderate policy to cut those emissions. The Trump Administration replaced it with a ridiculous token policy. The D.C. Circuit appeals court tossed that out. Now what? It wouldn’t be hard to redo the Obama policy …
