Milestones in State Climate Policy

The first efforts to clean up the grid date back forty years, but state climate policy really got moving at the turn of the century.

The federal government’s interventions in climate policy have been erratic, driven by political polarization and alternating control of the White House. In contrast, state governments have engaged in steady campaigns to reduce carbon emissions.  Some people seem to think this has been a recent innovation, but it has now been ongoing for a generation.  Here are some the key milestone along the way, closing with Trump’s pledge to bulldoze state policies that don’t fall in line with his priorities.

Crafting a Roadmap for Zonal Decarbonization in California

An overhead view of a residential street that captures that main road and the houses on each side with their front and back yards.

A new series of briefs from the UCLA Emmett Institute offers legal insights for the gas transition. First up: SB 1221.

California has a $43 billion problem: that is the estimated cost of maintaining the state’s gas network over the next twenty years. That is an astronomical amount to spend on what state policy dictates will eventually become stranded assets: California won’t be able to meet its ambitious climate goals unless it moves away from natural gas altogether, so retirement of these assets is …

Using Maps to Make Housing Politics Easier

Setting clear borders as to where upzoning to advance housing would apply may help ease the politics of housing policy

A recent article in the SF Chronicle highlighted how it has been easier for housing advocates to get upzoning reforms that facilitate housing production in Oregon – with the upzoning provisions in Oregon having significantly fewer exceptions and carveouts than comparable provisions in California.  The result is that Portland has seen more movement in housing …

How California (And Other States) Can Drive Demand for Clean Trucks

The cover for a December 2025 Policy Report titled, "Driving Demand: Solutions to Increase the Market for Heavy-Duty Zero Emission Vehicles," with UC Berkeley Center for Law, Energy, and the Environment, UCLA Emmett Institute on Climate Change and the Environment, and Bank of America listed as collaborators. The cover has a picture of a green 18-wheeler truck coming out of a factory.

CLEE and the Emmett Institute release new report today and will hold Jan. 13 webinar with Energy Commissioner Nancy Skinner keynote.

This post is co-authored by CLEE fellow Marie Grimm. California’s policies to phase out polluting diesel trucks with zero-emission models took a major hit this year from the federal government. In June 2025, Congress voted to overturn federal permission for California’s zero-emission truck mandate (although this vote is now subject to litigation). In July, Congress …

A Full-Court Press on Methane, Climate in the Governor’s Race

A methane flare broken down in colors.

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

Replacing high-carbon fossil fuels with clean energy while also adapting to climate change — that’s the ballgame. But we may not get to the ninth inning in one piece if we don’t deal with methane first. That’s one takeaway from the COP30 UN climate summit. Pick your metaphor — and there are many — but …

At a Loss for Words? Resist Climate Silence

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

A few years ago, I was writing about how President Joe Biden was flying around the country to promote his landmark climate law without uttering the word “climate.” Seems so quaint. Now, we find ourselves in a place where “climate change” is on a list of banned words maintained by the U.S. Energy Department, along …

California Takes a Stab at Climate and Energy Costs

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

It’s remarkable that with everything else that’s raging, climate and energy bills still managed to dominate the legislative session that just wrapped in Sacramento. After all, the reason lawmakers were still at work this past Saturday — the day after the legislative session was supposed to end — was that negotiations on climate bills pushed …

California Must Invest in Climate and Communities to Drive Climate Progress

The state has pioneered an approach—what’s worked, and what’s next?

As solar and other climate infrastructure construction accelerates, and with Californians concerned both about the cost of living and about seeing local opportunities result from climate projects, the conversation about community benefits (commitments to hiring and other local investments made by developers in connection with new projects) has grown increasingly animated in California and even …

Young Climate Plaintiffs Won Big in Montana. Can They Again?

A “Welcome to Montana” sign stands in front of a dramatic scene split between a wildfire with smoke and a landscape of cracked, dry earth under an orange sky, suggesting extreme weather or climate change.

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

One of the biggest climate victories to date belongs to 19-year-old Eva Lighthiser and the other Montana youth climate plaintiffs who won their landmark case against state officials and saw it upheld in the state Supreme Court. Now, some of those same young people — Lighthiser included — are headed back to court next week …
