Reducing Financing Costs for New Transmission in California

New CLEE Report Release & Webinar on Wednesday, November 13th at noon PT

California will need a significant build-out of new high-voltage transmission lines to meet state goals for renewable energy deployment and a decarbonized grid by 2045, which requires quadrupling its current in-state solar and wind capacity. But if this new infrastructure is paid for solely through electricity rates, it could increase them significantly, when they have …

No More ‘House of Horrors’ Thanks to These New Laws

Several California laws prohibiting dangerous chemicals from household products go into effect on or after January 1, 2025.

Halloween is the one time when we welcome ghouls, ghosts, and goblins coming to our homes (and, if your neighborhood is anything like mine, a variety of tiny superheroes). This season, however, the Legislature is dealing with a different kind of house of horrors: dangerous chemicals in everyday products that affect millions of Californians’ health. …

The 2024 Election Outcome Could Boost the Case for Geoengineering

Reflecting Sunlight: Recommendations for Solar Geoengineering Research and Research Governance (2021) cover

A Trump victory would increase the odds that we will ultimately need to start blocking solar radiation as a last resort to limit climate change.

A Trump victory would increase the odds that we will eventually need to “break the glass and pull the red lever.”  To be prepared for that possibility, we would also need to do more in the short term to research various forms of geoengineering, their feasibility, and their potential side effects.  Basically, if you decide you’re going to start smoking a lot more cigarettes, you need to be prepared for the greater likelihood you’ll need chemo.

New Environmental Laws Focus on Public Health

Many of the environmental-focused bills that the governor signed this year involve ways to alleviate the health disparities faced by frontline communities.

The California State Legislature is now finally in its off-season. Governor Newsom had until Monday, September 30th to sign or veto bills that the legislature passed and sent to his desk. In a final tally of bills, according to CalMatters, Governor Newsom vetoed approximately 18% of the nearly 1,000 bills that landed on his desk …

We Need a Circular Economy for EV Batteries

California got close to making suppliers ensure EV batteries are managed responsibly at end of life. Here’s why 2025 should be the year California creates a circular economy for EV batteries.

California continues to make significant headway toward its target to eliminate in-state sales of new internal combustion engine vehicles by 2035. About one in five new cars sold in California are battery-powered. And it’s not just California: Battery-powered car sales are up globally, with projections showing 17 million will be sold worldwide in 2024. As …

Model Uncertainty in Politics and Climate Policy

The polls could be systematically off, not just due to random error. That’s a worry with climate models as well.

Yes, your favored candidate could sweep the swing states, and yes, climate change could be more moderate than we now expect.  But that shouldn’t give you much comfort on either issue, since the errors could equally be in the opposite directions. 

Obviously, we’d like to improve our models, but that’s not always easy. In the meantime, the smart thing is to plan on the basis of the best models we have but avoid overconfidence about our predictions.

The Election, Vehicle Emissions, and State Climate Plans

If the California car waiver survives a possible Trump presidency, we may have the overruling of Chevron to thank.

If one single thing about the election keeps state environmental regulators up at night, it’s how much a Trump victory would impact their ability to cut transportation emissions. As it turns out, Trump’s leverage would be reduced, ironically enough, because his conservative Supreme Court appointees  helped overrule the Chevron doctrine.  Trump can still cause a …

Why You Should Read CA’s ExxonMobil Plastic Lawsuit

Plastic pollution choking an LA County waterway

California’s lawsuit against ExxonMobil for lying about plastic recycling is the latest example of the state using old-fashioned legal tools to address more modern harms.

The media have moved on (understandably) from California’s recent lawsuit against Exxon over plastic recycling to other environmental stories like Hurricane Helene’s catastrophic damage and Hurricane Milton’s terrifying, rapid intensification. But anyone interested in the problem of plastic pollution—which should, frankly, be everyone—will appreciate digging deeper than the Day One headlines to read California’s 147-page …

A Small Win for Curbside EV Charging in California

AB 2427 marks progress for a key charging segment

Late last month, Governor Newsom signed Assembly Bill 2427, which represents a modest step in the effort to ensure all Californians have access to convenient electric vehicle (EV) charging, not just those who own their homes and have garages, by supporting efforts to invest in curbside EV charging. As CLEE described in a report issued …

A Good Day to Drop Big Oil

Major league sports teams like to talk about sustainability measures on Green Sports Day, which is Oct. 6. They should do something about their fossil fuel sponsors.

On Sunday, October 6, sports teams throughout the U.S. will participate in something called Green Sports Day, an annual event to promote sustainability in sports. Often, it’s a chance for a franchise to promote the recycling or energy conservation that goes on at its stadium.  One thing these teams almost certainly will not be talking …
