Carbon pricing is one of our best assets for the climate. Over 80 countries now have a carbon price. Today we launch the Open Coalition on Compliance Carbon Market. Together with Brazil and other partners, let’s do it right, and let’s do it together.

Do not miss this one!

🚨 Carbon dioxide (CO₂) levels set a new monthly *record high* in May 2025 - 430.51 ppm (seasonal maximum) This is the second largest May-May increase in this dataset (3.6 ppm higher than 2024). This is not good... 🫣 Data from gml.noaa.gov/ccgg/trends/

I think Miliband is right in pointing out that we have made progress and the biggest reason why is the profit motive.

Nice proposal! While some countries are tempted to profit from the sacrifices of others [ahem!] without making any themselves, Boyer and Gollier propose that the EU and Canada unite to set a single price for carbon and impose a tax at their borders on external countries that avoid this constraint.

We’re probably at the stage where an asteroid hitting Washington DC and decapitating the US federal government would make the stock markets go up

For environmental political economy nerds: a yellow vest hangs in a window, at the French consulate in London.

Juan Pablo Rud Keynote presentation kicks off the congress of LAERE. Can windfall government transfers from mining royalties (“Canon”) boost local economic activity?

In the next few days, I will be sharing some of our work that I am most proud of from my time at NOAA/GFDL. But I would also like a little normalcy today on my feed, so here's my go-to sea ice data viz update. #Arctic sea ice extent still remains the *lowest* on record for the date (JAXA). Not good

Amazing.

Great paper by @tbourany.bsky.social . IAM with heterogeneous countries and international trade. Optimal climate agreement has incomplete participation, tax lower than SCC and substantial tariffs on non members.

Monday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 520,000 km² below the 2010s mean • about 1,050,000 km² below the 2000s mean • about 1,620,000 km² below the 1990s mean • about 1,940,000 km² below the 1980s mean Plots zacklabe.com/arctic-sea-i...

Second day of the RIDGE workshop on environmental economics. Invited lecture by Juan Pablo Montero on the optimality of low emissions zones and subsidies for EVs and hybrid cars.

Cristobal Ruiz-Tagle: prenatal and early childhood exposure to wildfires in Chile had long term effects on hospital admissions and educational outcomes.

The 6th RIDGE workshop on environmental economics kicked off at the Central Bank of Chile. Presenting now Pedro Costa. São Paulo School of Economics: Impact of sanitation on infant health in Brazil.

3 days to go!!

New publication: 🚨📑 In a new @centreeuropeanref.bsky.social policy brief, @aslak.bsky.social and I assess the impacts of the EU CBAM, one year after its implementation. What effects do we see on trade flows and trade discourse? What impacts has it had on climate policy? www.cer.eu/publications...

Are low-skilled workers the losers of the green transition? My JMP tests the skill-bias of green technology. I show that firms increase their demand for highly educated workers in manufacturing and transportation – in most other sectors, green technology favours workers without higher education 1/3

After many iterations my paper on endogenous climate in deforestation modeling is reborn! (an amazing photo from the one and only Sebastião Salgado:)

Carbon dioxide (CO₂) averaged 422 ppm in October 2024 10 years ago October averaged about 396 ppm Preliminary data: gml.noaa.gov/ccgg/trends/ 🧪⚒️

The extent of sea ice globally continues to be a record low for this time of year. Sea ice cover is currently quite low at both poles. More sea ice graphics available at zacklabe.com/global-sea-i... 🌊

It’s done. This is the moment Britains last remaining coal power station came off the electricity system for the final time, marking the end of 142 years of coal generating electricity in Great Britain. HT National Grid ESO
