How, Exactly, Has Trump Gone After EVs?
A close look at the Administration’s wreckage, in six steps
The second Trump Administration has brought a flood of obstacles to the national effort to transition away from petroleum-powered vehicles to electric vehicles (EVs). These challenges have come in many forms across multiple levels of government; they are in most cases completely unprecedented, and in many cases legally dubious (to put it mildly). The push …

Hegseth and the “God Squad” may have just stepped into a morass.
As expected, the Endangered Species Committee issued a blanket exemption, preventing any challenges to oil and gas drilling in the Gulf that threaten endangered species. Hegseth’s request for the exemption is premised on the existing (but possibly insufficient) protections that the government is currently giving endangered species. Thus, it’s not quite a license for Exxon to send out harpoon boats to kill off whales. It does, however, raise the suspicion that the current protections are grossly inadequate and that the government expected to lose in court, before in effect breaking the glass and pulling the red emergency lever.

The Iran War it is hitting energy markets hard. Will that affect the energy transition?
The Iran War has been a big shock to the global energy system. It’s natural to wonder what the long terms will be. What it will lead to an orgy of oil and gas drilling, or will it speed up the energy transition? There are enormous uncertainties, and making confident predictions would be a clear mistake. In this post, I’ll try to unpack some of the issues and offer a semi-educated gas about the answers.
Why do Governments Around the World Use Supply-Side Regulations to Boost Clean Transport?
New CLEE report explores the benefits these policies provide to transition off fossil fuel dependency
While the U.S. may be backsliding on requiring more fuel efficient and zero-emission vehicles, the story globally is largely the opposite. Governments around the world are still seeking to improve air quality and meet greenhouse gas goals and are increasingly moving towards supply-side regulations for their vehicle fleets. These policies include fuel economy standards, emission …
CONTINUE READINGDoes Federal Law Still Preempt State Standards Relating to Fuel Efficiency?
The answer may depend on what being “in effect” means.
If a tree falls in the forest but no one hears it, does it still make a sound? If a law hasn’t been formally repealed but can be violated with complete impunity, is it still in effect? This matters because federal law preempts state fuel efficiency standards if, but only if, a federal standard is “in effect.” Congress just eliminated any penalty for violating the federqal standards. Which means at best they have only a kind of ghostly existence, but no substance to speak of.

First in a series of posts outlining key challenges and opportunities facing California’s next governor.
In collaboration with California Environmental Voters, CLEE is leading a nonpartisan initiative to educate all candidates running for governor, as well as the public, on critical climate, energy, and environmental issues. In February, CLEE and CEV co-hosted a candidate forum featuring 90 minutes of discussion on these issues. And we’ve launched a public website, www.climatevote.org, …

CONTINUE READINGWhat Happens to State Regulation if the Endangerment Findings are Gone?
Answer: State authority wouldn’t suffer from the change and might expand in some ways.
If the Trump EPA successfully repeals the endangerment findings for vehicles and stationary sources, states will be the only resort for climate regulation. A key question is how the repeals would impact state power to regulate carbon emissions. The bottom line answers are: (1) the impact on state power regulate tailpipe emissions seems unclear but could be positive, (2) there would be no effect on state power to regulate stationary sources like power plants, and (3) plaintiffs suing oil companies would probably benefit. The detailed analysis is below.
CONTINUE READINGThe Overlooked Precedent Supporting EPA Regulation of Greenhouse Gases
Even Roberts and Scalia agreed that Mass. v. EPA is the law
An important precedent has been overlooked in the coverage of the Trump EPA’s repeal of the 2009 Endangerment Finding. The 2009 finding relied was based on , in which the Court had held that the Clean Air Act covers air pollution and directed EPA to determine whether greenhouse gases are harmful. One reason to worry about the litigation is that the conservatives Justices all dissented from Massachusetts v. EPA over the repeal. But there’s another equally important precedent: American Electric Power v. Connecticut (AEP). That ruling was joined by Chief Justice Roberts and Justice Scalia, so it may carry more weight.
CONTINUE READINGThe Affirmative Case for Finding Endangerment
Despite hairsplitting by the current EPA, finding endangerment is a no-brainer.
or EPA to decide that vehicle greenhouse gas (GHG) emissions aren’t harmful is iike NASA deciding that the earth isn’t round after all. Over the next year or two, lawyers will be picking over EPA’s detailed legal arguments. Let’s not get mired in the weeds. It’s crazy that this issue is even being raised.
In 2007, the Supreme Court told EPA to do two things: (1) consider whether GHGs endanger human health and welfare, and (2) if the answer is yes, regulate vehicle emissions of GHGs. That’s exactly what EPA did. Nothing has changed in the meantime.
Hot Take on the Endangerment Repeal
It’s a tweaked version of arguments that the Supreme Court rejected in 2007.
EPA’s argument for repealing the Endangerment Finding is basically a rehash of legal arguments that were rejected by the Supreme Court in 2007. These arguments haven’t improved with age. Notably, EPA doesn’t dare contest the science.
