New Bill Takes Up Local Oil Drilling Phase-Outs

Oil and gas interests want to weaponize new case law from the California Supreme Court. AB 3233 would clarify the scope of local authority over drilling operations.

When the California Supreme Court ruled last August that Monterey County could not enforce its voter-approved ban on new oil and gas wells, lawyers for Chevron said the company was “pleased” to end the 7 years of litigation.

The New EPA Car Rule Doesn’t Violate the Major Questions Doctrine

They both relate to climate, but West Virginia v. EPA involved a very different regulation raising very different issues.

In West Virginia v. EPA, the Supreme Court struck down the Obama-era Clean Power Plan.  The heart of the ruling was that EPA had engaged in a power grab, basing an unprecedented expansion of its regulatory authority on an obscure provision of the statute.  Conservative groups have claimed since then that virtually every government regulation …

Replacing McConnell

If the GOP flips the Senate, who will lead them on environmental issues?

Who will lead the Senate in 2025?  The odds are that it will be a Republican. Democrats have a slim margin and face some close races, while all the GOP seats seem secure. That makes the question of who will replace Mitch McConell as GOP leader all the more important for climate and energy policy. …

How to Cooperate with China on Climate

A conversation with Joanna Lewis about what has worked, and what hasn’t, when it comes to bilateral climate cooperation with China.

China is the world’s largest producer of both CO2 emissions and green technology to cut those emissions. It installed more solar panels last year than the U.S. has in its history, and yet keeps building coal-fired plants too. And Chinese officials just announced that the country will accelerate the construction of solar, wind and hydropower. …

Duncan McLaren and Olaf Corry reflect on the implications of the UNEA-6 non-decision on solar radiation modification for research and governance

As we wrote in part 1, a Swiss-led proposal to the UN Environment Assembly (UNEA) to establish an expert group on solar radiation management (SRM) proved divisive and was eventually withdrawn. Here we explore why, and what that means for any global conversation about SRM. SRM has long generated concerns that, as a powerful lever …

The SEC’s Watered-Down Climate Rule

Now that the SEC has approved its limited climate disclosure rule, the spotlight is back on California’s more stringent disclosure laws that still need backing.

After months of discussion, the U.S. Securities and Exchange Commission (SEC) voted 3-2 to adopt climate reporting standards that will mandate publicly-traded companies disclose some of their greenhouse gas emissions. The SEC’s rule was proposed way back in 2022, and the initial draft would have required companies to disclose their “Scope 3” supply chain emissions, …
