Guest contributors Maeve Anderson and Mackay Peltzer write that regulatory updates are needed to ensure California’s coastal planning remains consistent with the intent of the Coastal Act.

California’s iconic coastline is simultaneously a source of pride and tension for the state. As increasingly severe storms, intensified by climate change, accelerate the erosion of beaches and bluffs, the conflict around land use at the coast has also intensified.  Nowhere exemplifies this reality better than the City of Pacifica, a popular surfing destination located …

Takings Between the Sheetz

…in which I actually praise Brett Kavanaugh

It seems absurd to blog about legal doctrine nowadays, but I, like many, am preparing for Spring term classes, and Takings represents one way that the Supremes might try to destroy American government. So it is always good to keep it in mind. Most of us know the issues concerning exactions – when a government …

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 …

Everything is Awesome!

A line graph of metric tons of CO2 over time titled, "China's O2 emissions have now been flat or falling for 18 months. Emissions from fossil fuels and cement, MtCO2, rolling 12-month totals."

Well, not really, but China’s astonishing progress in curbing emissions points to a technological way forward — and how the United States is being left behind.

There is so much that is awful, so let’s see some good news for once: China’s carbon dioxide (CO2) emissions were unchanged from a year earlier in the third quarter of 2025, extending a flat or falling trend that started in March 2024. The rapid adoption of electric vehicles (EVs) saw CO2 emissions from transport fuel drop by 5% …

The Promise and Growing Pains of Managed Aquifer Recharge

field flooding for recharge

By Dave Owen, Helen E. Dahlke, Andrew T. Fisher, Ellen Bruno, and Michael Kiparsky

  Around the world, groundwater mismanagement is a major driver of water crises. An emerging method for addressing such mismanagement, called managed aquifer recharge, has generated excitement among scholars and water managers. In a newly published article (Owen et al. 2025), we argue that this excitement, while often justified, should also be tempered by acknowledgment …

What to Know About the TFFF Announced at COP30

Four different images of lush trees, forests, and jungles.

A bold new investment fund aims to channel billions into tropical forest protection – one key change can make it better.

The world is losing vast swaths of forests to agriculture, logging, mining and fires every year — more than 20 million acres in 2024 alone, roughly the size of South Carolina. That’s bad news because tropical forests in particular regulate rainfall, shelter plant and animal species and act as a thermostat for the planet by storing carbon, keeping it out of …

Is Diversity A Strength? Not Always

On the left side of the image is a headshot of Andrew Cuomo and on the right side is a headshot of Zohran Mamdani.

Environmental history shows that specifics matter

To absolutely no one’s surprise, Zohran Mamdani defeated Andrew Cuomo Tuesday in the race for the Mayor of New York City, becoming the Big Apple’s first Muslim mayor. Also to absolutely no one’s surprise, much of the campaign against Mamdani descended into Islamophobia – less from Cuomo himself and more from his supporters and outside …

Lighting Candles in Dark Times: Environmental Law Centers in the Trump Era

These law school centers show it’s possible find ways to make a difference.

Environmental law  have become vibrant parts of the law and policy ecosystem. At a time when despondency seems all too common, the work of these law school centers offers beacons of hope for the future of environmental protection.  Some of that work is playing defense — pushing back against deregulatory efforts — while other work plays offense by identifying innovative directions for environmental policy. A comprehensive survey isn’t practical, but I’ll provide examples from several different centers.

This week, California Governor Gavin Newsom led a high-level meeting with Brazil’s Environment Secretary Marina Silva to expand the long-running partnerships that exist between the Golden State and the largest country of Latin America. The meeting resulted in a new Memorandum of Understanding (MOU) between both governments to continue to collaborate on climate action. Although …

The perils of federal abundance legislation

Political polarization at the federal level is a steep obstacle to any major abundance reforms

I recently wrote an assessment of the ROAD Act, a bill in the US Senate that would do some (mild) changes to NEPA and develop some guidelines and incentives for state and local governments to amend their zoning to facilitate more housing production.  While the ROAD Act may be fine policy, one question is whether …
