Enhanced rock weathering is a carbon removal technique gaining lots of attention, but we’re still figuring out best ways to do it. In collab with @climatejesper.bsky.social, we synthesized scientific results to explain what we know, and grapple with what we don’t. carbonplan.org/research/enh...

Carbon credits are everywhere, but the data about where they come is hard to track down and difficult to work with.
OffsetsDB is a new database that collects, standardizes, and provides daily updates of offset project data from five of the largest registries.

I wrote a pair of short blog posts on the climate value of temporary carbon storage, now available at the Kleinman Center for Energy Policy at Penn. Part 1 explains why temporary offsets are *not* equivalent to the permanent harms of CO2 emissions.

Earlier this year I (with Frances Sawyer) published a paper suggesting the 45Q CCS tax credit is structured in a way that could incentivize huge costs + increased GHG emissions from the US power sector. DOE rebutted it, and we were allowed to reply. Those pieces are up today:

Exclusive: UC researchers were tasked with finding carbon offsets the university system could rely on to cancel out emissions. But they couldn't. Now, all 10 campuses are being charged a carbon fee that will be invested into direct emissions reductions instead.

🧵In the newly published Best Practices Guide to Ocean Alkalinity Enhancement (OAE) Research, we make recommendations for monitoring, reporting, and verification (MRV), the multistep process to quantify the amount of CO₂ removed by OAE, a promising CO₂ removal technique. 1/5

I wrote about California Governor Gavin Newsom's ambivalence toward corporate climate accountability laws for @heatmap.news, drawing on his response to four new bills the state legislature sent to his desk this year.
tl;dr one veto and two hostile signing statements that could chill implementation

Heidi Blake has a long piece in the New Yorker on carbon offsets. No matter how bad you think things are, the people involved in big projects keep telling us how much worse things actually are.

There is increasing evidence that the world has warmed faster over the past 15 years than it has since the 1970s. Surface records, ocean heat content, and the Earth's energy imbalance all support an acceleration of warming, as I argue in today's @nytimes.com: www.nytimes.com/2023/10/13/o...
