Lionesses. Utterly brilliant. Spain were Amazing. Great final. Rather emotional in this European household.

Researchers including Professor @bengroom.bsky.social are working to restore trust in carbon offsetting by demonstrating the more robust ways their impact can be measured. @leepinstitute.bsky.social @exeter.ac.uk news.exeter.ac.uk/faculty-of-e...

One last view over Bergen following a nice #EAERE2025 conference. Always happy to meet friends and colleagues I seldom have the occasion to cross paths with. Including @profejzrobinson.bsky.social @bengroom.bsky.social @elchinosauro.bsky.social And many others @eaere.bsky.social

I was recently asked “What is the most important piece of advice you would give to a new assistant professor?” My new blog post covers the answer. #EconSky

Our latest working paper provides new insights into the economic value of the Congo Basin forests and how the supply of this value is distributed across categories of rightsholders, thereby linking values to the different groups who make management decisions about the forest. www.lse.ac.uk/granth...

I ll present on Tuesday at 2 pm in the session “Forests, land use, and economic development”

Listening to PM on BBC R4 today you would think that the Treasury Green Book is the source of all problems concerning levelling up, regional disparities of government investment and inequality writ large. The Green Book handles value for money. Not the lack of strategy by successive governments.

@moritzdrupp.bsky.social, my supervisor Martin Hänsel and co-authors incl. @bengroom.bsky.social @climatefran.bsky.social @frikknesje.bsky.social @ctraeger.bsky.social were recognized with the Frontiers Planet Prize for planetary health with a paper on the increasing value of nature

There are ways the grid operator can kind of manage this today, but it would happen much more directly if the prices in different parts of the country better reflected the supply/demand balance from hour-to-hour in each region. That’s the idea anyway.

Thank you EDF for requesting this FOIA together the latest EPA GHG Inventory out. We may need to do the same for facility-level GHG emissions from EPA's GHG Reporting Program.

What self-respecting tree surgeon goes ahead with this unquestioningly? Perhaps linking ati.woodlandtrust.org.uk (ancient tree inventory) with upcoming jobs via the @arbassociation.bsky.social would be a good way of quickly raising red flags? Is this a new idea? www.bbc.co.uk/news/article...

This editorial is worth a close read, and a course of action. Fight like our democracy depends on it, because it does. www.nytimes.com/2025/05/01/o... [gift link]

"It is to build a coalition of Americans who disagree about many other subjects...yet who believe that these subjects must be decided through democratic debate and constitutional processes rather than the dictates of a single man." Read, discuss, share. Don't ignore.

On climate policy, all eyes are on California's reauthorization of its world-leading cap-and-trade program. Today, I had the privilege of testifying about the program and its revenue spending priorities before the CA assembly climate budget subcommittee. Start at 1:01:30. #climatesky #energysky

Carbon border adjustment mechanism policies reduce emissions leakage, boost domestic competitiveness and encourage global carbon pricing — without disproportionately harming lower-income countries from @kclausing.bsky.social, Colmer, Hsiao and @cwolfram.bsky.social https://www.nber.org/papers/w33723

Amazing work @bengroom.bsky.social. Did we mention Ben works on the RENEW project? Just saying.

Funny not funny.

The XXVI Annual BIOECON Conference on "Integrating Biodiversity Conservation and Climate Change Solutions," taking place on 1-2 September 2025 at St. John’s College, Cambridge University. Call is here. SUBMIT!! @GRI_LSE @UniofExeterNews @EAERE_envecon www.bioecon-network.org/pages/26th_2...

BIOECON Deadline today!!! Submit your papers on the economics of biodiversity, ecosystem services and conservation. It’s at St John’s, Cambridge Uni. August 31st to September 2nd. Below

This happened. More to follow on the journey that culminated in the paper and how @moritzdrupp.bsky.social and Martin Hansel guided it through. @leepinstitute.bsky.social @universityofexeter.bsky.social www.lse.ac.uk/granthaminst...

Looking forward to an insightful discussion on the future of EU climate policy for @jungeakademie.bsky.social and with the Young Academies of Ireland, Italy and Sweden and the Global Young Academy, on May 27 (register under link 👇) www.diejungeakademie.de/en/events/kl...

This looks like a great opportunity : www.bangor.ac.uk/sns/commonwe...

A classic paper by Ben Bernanke (from 1980!) seem especially salient today. Perhaps more than ever before. It was eventually published in QJE in 1983. www.nber.org/papers/w0502

Articles like these are total BS. Russia has been declaring "ceasefires" like these for years (including pre-full invasion), then not respecting them itself. These "ceasefires" are not a sign of anything. www.bbc.com/news/article...

Just under two weeks left for applications to this postdoc position. Come join us at LSE! #econsky

Note that this is decidedly different from saying Trump can halt the low-carbon transition. He can't: gwagner.com/policy-pendulum But he can surely delay things, and hurt US competitiveness in the process. And the erratic nature of it all, of course, only hurts.

"Many of the world’s largest shipping nations decided on Friday to impose a minimum tax of $100 for every ton of carbon dioxide emitted by ships...effectively the first global tax on greenhouse gas emissions." apnews.com/article/ship...

Really good analysis. The basics are important.

Aggregate US prices rise by 5%. Sectors with >8% US price increase are metals, clothing, electronics, food, chemicals, and other industrial products. /n

Just a reminder that there is no existing substitute for NIH in terms of biomedical research funding--anywhere in the world. These losses will be felt worldwide. And given spending as of the end of March, we're looking at an effective 60% cut to NIH funding.

Madness. These exports help fund our own students and funnel £ into the university towns and cities outside London. We should be looking to expand capacity to take in foreign students who would previously have chosen the US.

One challenge for trade policy, is that the benefits to consumers (like lower prices) feel vague & abstract—it's hard to see what we'd lose without free trade. Job threats feel immediate, driving support for protectionism. More recent on views on trade👇

(1) Rapid GE trade modeling returns for April 2nd tariffs. We model: April 2nd tariffs + 25% on CAN/MEX imports + 20% on PRC imports + 25% on iron/steel/alum/cars. Fig. shows total tariff by country. Avg. is 20.4%, about 10X pre-Trump rates. What are US and foreign country impacts?

I’m going to start using this phrase, probably daily, as a means of diluting / coping with the dystopic. “What is this place you’ve brought me to Roger?”. Reliable and actual comedy from Alexei Sayle. www.bbc.co.uk/sounds/play/...

🤩🤩 Paper finally out in the AER! With my co-authors (incl. @bluebery-planterose.com & @s-stantcheva.bsky.social) we surveyed climate attitudes in 20 countries covering 72% of global emissions. In brief, people want ambitious, global, and fair climate policies. A 🧵⬇️ www.aeaweb.org/articles?id=...

Funny, I was just thinking that this is a possible framing for all this. $50 is the Obama SCC more or less. It is possible to administer carbon taxes without being so regressive though.

A great job in environmental politics👇

If you like maps, here is a PhD opportunity to work @inrae-france.bsky.social with the wonderful @leatardieu.bsky.social

@ctraeger.bsky.social & I have a chapter in the new Handbook of the Economics of Climate Change (Eds: Lint Barrage & Sol Hsiang, Elsevier)! We synthesize insights from 2+ decades of research on how uncertainty shapes optimal climate policies and affects the SCC. Our main takeaways: 🧵 1/

Thrilled to be attending LAERE 2025 in beautiful Bogotá! Today at the keynote session by @bengroom.bsky.social, exploring practical ways to price biodiversity. Also, excited to reconnect with colleagues and especially happy to return to Uniandes after so many years. 💚

@uknee.bsky.social EnvEcon in full swing at the @royalsociety.org . Excellent conference as always.

Learning the 'lay of the land' of the carbon dioxide removal industry can be very time-consuming for newcomers. To speed up this process and make it a bit easier, I've created a concise resource guide designed for those looking to enter the field. open.substack.com/pub/rickberg...

This short piece is well worth your time. Europe either stands together or falls as individual member states. The suggestions here may sound impossible, unimaginable, but we live in truly exceptional times and must strive for exceptional solutions.

New paper out with the marvellous Frank Venmans. “The Social Value of Temporary Carbon Removals and Delayed Emissions”. Emissions delays can be valuable sometimes, even if not permanent. Temp-perm equivalence is useful, but transparency needed. www.journals.uchicago.edu/doi/10.1086/...
