Trump’s Greenhouse Gas Rule Will Get a Court Test Sooner Than We Thought The Supreme Court agreed to hear Suncor Energy Inc. v. County Commissioners of Boulder County, which concerns jurisdiction for “public nuisance” claims.

The federal government claiming state preemption after killing the endangerment finding “feels like a bad ex-boyfriend who says, I don’t want to date you anymore, but you can’t date those other people either,” Georgetown Prof. Vicki Arroyo told @emilypont.bsky.social

Trump’s Greenhouse Gas Rule Will Get a Court Test Sooner Than We Thought The Supreme Court agreed to hear Suncor Energy Inc. v. County Commissioners of Boulder County, which concerns jurisdiction for “public nuisance” claims.

It will take years for cases related to the Trump EPA's repeal of the endangerment finding to work their way through the courts.

Meanwhile, SCOTUS just agreed hear a case that touches on many of the same arguments.

Trump’s Greenhouse Gas Rule Will Get a Court Test Sooner Than We Thought The Supreme Court agreed to hear Suncor Energy Inc. v. County Commissioners of Boulder County, which concerns jurisdiction for “public nuisance” claims.

Legal challenges to the EPA's big reversal on the endangerment finding could take years to get to the Supreme Court.

But the Court will now have to confront the agency's actions as soon as this fall when it reviews Colorado's lawsuit against Exxon.

How to Save Ski Season Europeans have been “snow farming” for ages. Now the U.S. is finally starting to catch on.

Sometimes solutions are deceptively simple. As in: Ski areas aren’t getting enough snow to open for the season? What if you made a REALLY BIG PILE OF SNOW to save for the next year? heatmap.news/adaptation/s...

This bill passed the state House yesterday, albeit with some trimming to get it past the Microsoft/Amazon lobby. It's still a good bill implementing the recommendations of our data center workgroup. Also need to pass 2245/5982, to make sure large new loads comply with the 100% clean electricity law.

The 3 Arguments Trump Used to Gut Greenhouse Gas Regulations Whether any of them will hold up in court is now the big question.

How did EPA ultimately justify its decision to reverse course on greenhouse gas emissions?

The agency's 3 arguments will define the inevitable court battle over this move. Here's what they are. heatmap.news/climate/epa-...

The Trump administration finally issued its justifications for repealing the endangerment finding for greenhouse gases.

Now the big question: Will they hold up in court?

This New Wildfire Risk Model Has No Secrets CarbonPlan has a new tool to measure climate risk that comes with full transparency.

I wrote about the first 100% transparent climate risk tool. You can look up your home's wildfire risk, w/ all underlying data, methods, and code available to dl. The hope is to get this info out of black box models and invite public/scientific scrutiny and collaboration. heatmap.news/adaptation/c...

The Climate-Smart Program Trump Didn’t Kill (Yet) New guidelines for the clean fuel tax credit reward sustainable agriculture practices — but could lead to greater emissions anyway.

The Treasury's guidance for 45z, the Clean Fuel tax credit, indicates its moving forward with allowing biofuels producers to account for "climate smart agriculture" — which could ultimately just make the credit an even bigger subsidy for ethanol heatmap.news/politics/45z...

The 3 Big Unknowns About the EPA’s Biggest Climate Science Rollback Ever What to watch for when the agency releases its final decision on the greenhouse gas endangerment finding.

We are expecting the EPA to make a decision about its "endangerment finding" for greenhouse gases in the next week or so. While many expect the agency to rescind it, there's a few important questions to look out for about how the move is justified. Here's why. heatmap.news/climate/epa-...

Why Michigan’s Big Oil Lawsuit Is Not Like the Others Fossil fuel companies colluded to stifle competition from clean energy, the state argues.

Michigan's new fossil fuel lawsuit is fascinating. The state is alleging antitrust violations, arguing that Big Oil colluded to stifle competition. I spoke to experts about the case and the challenge of proving conspiracy vs. independent responses to market pressures. heatmap.news/climate/mich...

The great e-bike crackdown has begun New Jersey just approved a wildly out-of-step new law that restricts all e-bikes, regardless of speed or power capabilities. Will other states follow?

"Forcing someone who owns an e-bike without a throttle that can’t go faster than 20mph to register their bike with the DMV, acquire a license, and buy insurance ... will absolutely harm efforts to encourage more sustainable transportation" -@andyjayhawk.bsky.social

there's a new-ish player in the world of ultra-long duration (100+hour) battery storage: Noon Energy. last week, the startup announced the successful demo of its carbon-oxygen battery, which it hopes to commercialize as soon as next year to provide behind-the-meter power to data centers

Chris Wright Is Overhauling $83 Billion of Loans. He Won’t Say Which Ones. The Secretary of Energy announced the cuts and revisions on Thursday, though it’s unclear how many are new.

The DOE revealed today that it cancelled some $30 billion in loan guarantees for Biden-era clean energy projects and is "revising" another $53 billion worth. Those numbers include public cancellations from last year like Grain Belt, but the remainder is ????

Scoop: Trump Administration Refuses to Allow Safety Fixes at Vineyard Wind The offshore wind developer was in the process of completing necessary repairs when the administration issued its stop work order, according to court filings.

Vineyard Wind is sounding the alarm that Trump's stop work order is getting in the way of its efforts to replace the defective blades that caused the 2024 broken blade fiasco, paradoxically creating new hazards.
