A view from the Youth Climate Strike in S.F.

Youth Climate Strike signs and the young marchers holding them in San Francisco today were fed up, hopeful, witty and powerful—and offered helpful lessons to those of us entrusted with training the next generation of environmental advocates. Protesters offered concrete green visions (Only 363 offshore wind turbines needed to power the city of San Francisco); […]

Welcome to the Next Phase of the Great California-Trump Car Wars

First lawsuit filed, more to come

California didn’t wait long to file its first court challenge to the rules just finalized by the Trump Administration related to California’s GHG and ZEV car emissions standards (discussed here and here by Julia and Ann).  Here’s the complaint filed by California together with 23 other states, along with the cities of LA and NY.  […]

CLEE comments on Governor Newsom’s water portfolio executive order

Governor Gavin Newsom has directed state agencies to prepare a water resilience portfolio. Executive Order N-10-19 describes a set of broad principles to inform the development of the portfolio, as well as extensive outreach that should accompany the process, which is being conducted on an aggressive timeline. The EO states, correctly, that California needs a […]

EPA/Transportation Announcement of California Waiver Revocation is Full of Falsehoods and Irony

How Many Misstatements Can You Find?

This morning, the Environmental Protection Agency and Department of Transportation formally announced — as expected — that the Trump Administration is revoking California’s waiver to set its own vehicle standards. Yesterday, Trump tweeted the news, coupling it with falsehoods claiming that the rollback would save lives and save consumers money.  As I blogged yesterday, both […]

American Public Wakes Up, Smells the Coffee

Further evidence of a shift in public opinion on climate change.

As I discussed in a September 9th post, public opinion has been shifting toward greater recognition of climate change and the need to respond.  Much of the evidence came from polls dating back a few months. Further evidence is provided by two polls released this week. People do seem to be waking up to the […]

Trump’s Tweet about Yanking California’s Waiver is, Shockingly, Full of Falsehoods

The rollback will not make drivers safer and will not save consumers money

President Trump just sent out a series of tweets announcing and defending his decision to revoke California’s permission to issue its own tough standards to reduce carbon pollution and require manufacturers to sell Zero Emission Vehicles in the state.  Julia has a great analysis of why the decision is terrible policy and bad law that […]

Trump Announces Waiver Rollback on Twitter

Revoking California’s Clean Air Act Waiver Is Bad Policy and Legally Indefensible

This post was originally published on the American Constitution Society’s Expert Forum on September 18, 2019.  President Trump announced the revocation on Twitter this morning. It’s not news that the Trump administration has been planning, via its so-called SAFE Rule, to freeze Obama-era fuel economy standards, roll back tailpipe greenhouse gas (GHG) emissions standards, and […]

Black Carbon, 3 Billion Strong

I have been blogging about climate solutions and barriers to implementation and scale. Among the most important solutions are those that address short lived climate pollutants, primarily methane, black carbon, and HFCs, because if we stop or sequester those emissions, they will disappear from the atmosphere relatively quickly, unlike CO2. According to the UN Climate […]

A Welcome Victory in the D.C. Circuit

This is what it looks like when judges just buckle down and do their jobs.

Last Friday, the D.C. Circuit decided Wisconsin v. EPA. The federal appeals court rejected industry attacks on a regulation dealing with interstate air pollution but accepted an argument by environmental groups that the regulation was too weak.  Last week also featured depressing examples of the drumbeat of Trump Administration rollbacks, so it was especially nice […]

Green Growth That Works

New book explores natural capital policy and finance mechanisms from around the world

Since the Industrial Revolution, growth in human numbers and economic activity has dramatically transformed our planet. Rapid economic development has lifted hundreds of millions of people out of poverty and raised the standard of living and life expectancies of many more, but these forms of growth have also deeply eroded the natural capital embodied in […]

What Hath California Wrought?

Has California climate policy succeeded? Yes, but it’s complicated.

California’s climate policy have been a success, but quantifying the effects is complicated. It’s harder than it might seem to determine whether a climate regulation has succeeded.  California has clearly hit or exceeded its target for overall carbon emissions reductions under its method of carbon accounting.   But if we ask how much global emissions are […]
