(1/2) Such a pleasure discussing the importance of the EU CBAM for climate policy with Arvid Viaene. Listen to his podcast to hear more about our work on the Global Effects of CBAM, with @allanhsiao.bsky.social @cwolfram.bsky.social and @jmcolmer.bsky.social. www.buzzsprout.com/2412056/epis...

The DROP Act is introduced in the House with a heavy-hitting set of co-sponsors. mccaul.house.gov/media-center...

Good news re #CBAM in the EU-India trade deal: It's intact, and, even better, the EU committed not to give other countries a break. They also committed to support decarbonization in India to the tune of 500 million euros. www.reuters.com/sustainabili...

Yes, EU CBAM pushing Indian steel producers toward greener production processes. I only wish people would stop referring to #CBAM as a tariff. Tariffs treat foreign and domestic producers differently, while a CBAM levels the playing field. More like a VAT. www.canarymedia.com/articles/gre...

Anyone in #Canada selling swag off @mark-carney.bsky.social speech yet? A "Take Down the Sign" hat? Or too American? @blakeshaffer.bsky.social

Keeping an eye on this and hoping the EU holds firm on #CBAM. My read is that there's some chance of a fertilizer exemption but that's just the kernel of an idea right now. www.spglobal.com/energy/en/ne...

Graham sanctions bill may be moving forward. Ideally, Graham would work with McCormick and adopt parts of the DROP Act. www.politico.com/live-updates...

Here’s an interesting fact about the Venezuelan oil and gas sector: it’s ridiculously, off-the-charts dirty when it comes to methane emissions. In some earlier work, we had to change the scale to show Venezuela’s methane emissions per unit of energy produced.

I'd say the article answers the headline with a "yes", including quotes from @gzachmann.bsky.social at @bruegel.org. www.barrons.com/news/europe-...

Looks like the initial data on NYC congestion pricing say it’s working. 👏 🔌💡 #TalkAboutClimate www.bloomberg.com/news/article...

Households face annual costs of roughly $400–$900 from climate change—mainly from disasters, higher insurance, and energy costs—with lower-income families and certain regions hit disproportionately, from @kclausing.bsky.social, Knittel, and @cwolfram.bsky.social www.nber.org/papers/w34525

Faculty member @cwolfram.bsky.social efforts at #COP30 helped lead an international effort to strengthen and coordinate carbon markets reminding the U.S. carbon-pricing is "alive and well" globally.

An @eenews.bsky.social report on the Open Coalition on Compliance Carbon Markets. (People who have heard me talk about these issues recently won't be surprised that I'm the expert in the subtitle!) www.eenews.net/articles/new...

Canada's pipeline deal seems poised to strengthen industrial carbon pricing in Alberta (though "weak" carbon pricing in Canada is ~USD 65/ton on the margin). Go @mark-carney.bsky.social! www.politico.com/news/2025/11...

Really enjoyed this conversation with @jc-econ.bsky.social and Seth Carpenter. Thanks to @wendyedelberg.bsky.social for expert moderation and @brookings.edu for hosting! The event has passed, but you can still watch the video.

Climate inaction is ALREADY a big expense affecting US households' costs. One of the biggest? The impact of climate-related natural disasters on housing costs. New post and research by @kclausing.bsky.social @knittelmit.bsky.social @cwolfram.bsky.social legal-planet.org/2025/11/20/c...

Beautifully said by Daouda Sembene, PhD in this @cgdev.org blog post. Im so happy to have Daouda on our Global Climate Policy Project at Harvard and MIT climate coalitions working group! www.cgdev.org/blog/africa-...

Happy to be interviewed by @folha.com over the weekend about Brazil’s Open Coalition on Compliance Carbon Markets. The headline for the interview is (according to Google's translation), “The next step is to convince India, says the creator of a global carbon market.”

Próximo passo é convencer a Índia, diz Catherine Wolfram

The EU and China both endorse the Open Coalition - that's huge.

"EU, China Said to Join Brazil-Led Carbon Market Coalition" So, so thrilled to see this come together! Huge congrats to Cristina Reis (MofF, Brazil) and her team for getting it done and lining up so many of the important countries. Why is this important? A 🧵 www.bloomberg.com/news/article...

So fun to work on this with @brookings.edu.

Nice coverage of Brazil's push "to create a coalition of nations that would charge domestic manufacturers for carbon emissions and tax some imports from countries not in the coalition." And it's formidable leader Cristina Reis! #COP30 subscriber.politicopro.com/article/eene...

Really fun listen. My only minor complaint is that they describe the amassing of the shadow fleet as an "unintended consequence," suggesting that policymakers didn't expect it. I know for a fact that's not the case! Maybe economists should replace "unintended" with "unavoidable" (Greek shippers?)

More pressure on Russia, and on Trump to keep the pressure up. www.bloomberg.com/news/article...

Oil prices in Asian trading are up a bit on these reports, but maybe the market is flush enough to absorb some shut in of Russian oil? oilprice.com/Latest-Energ...

Curious to hear from others who subscribe to Carbon Pulse. I see a fair number of headlines I’d like to click through to, like the one below, but the subscription price is steep! Worth it? #climatesky

This is described as an "exemption" but since the UK and EU plan to align carbon markets so that UK and EU firms will pay the same price that's not quite right. It's instead aligned w the EU intent to credit domestic prices already paid. More a mini coalition! www.theguardian.com/politics/202...

Two points counter the top-line narrative in this piece: 1. Work by @constanzaabuin.bsky.social suggests that exporting more Canadian LNG can lower GHG emissions abroad, at least in the short run 2. The coming "climate competitiveness strategy” could be a #CBAM?!? www.wsj.com/world/americ...

Thanks to @kclausing.bsky.social for the great thread on our BPEA paper with @knittelmit.bsky.social! Bottom line: US households experience climate change primarily through wildfires and storms more than heat.

"The EU and China have expressed interest in joining the agreement, which may make it one of the most significant outcomes of the November summit..." Let's hope!! www.bloomberg.com/news/article...

NYT piece on Russia's shadow fleet frustratingly treats the build up of the fleet as an inevitable response to the price cap. That's not at all the case. The EU could have prohibited oil tanker sales to Russia, but for (I've heard) the desires of the Greek shippers. www.nytimes.com/2025/09/20/w...

I'm delighted to announce the release of the Flagship Report of the Global Climate Policy Project at Harvard and MIT Working Group on Climate Coalitions on "Building a Climate Coalition: Aligning Carbon Pricing, Trade, and Development." ceepr.link/3VmgC7g A 🧵 on what we do/find:

Interesting. This would presumably make it harder for the Democrats to pursue @ezrakleinbot.bsky.social's strategy to use gov't funding to extract concessions on domestic issues. www.politico.com/news/magazin...

Interesting that he didn’t mention purchases of Russian gas, which would be harder to stop buying, I’d guess.

COP30 President André do Lago and I took stock of recent developments as preparations for the COP intensify. We have important priorities, such as submitting good new NDCs, developing adaptation indicators and highlighting effective policy approaches like carbon pricing at COP30.

Nice coverage of the climate coalition work in today's FT! "Brazil now wants to use the COP30 presidency to push for a different international carbon pricing framework — one based on multilateral agreement, rather than with the EU as the de facto sole standard-setter." on.ft.com/4p0UnBv

Lessons from 3 years of Russia sanctions: (i) financial sanctions don't work on current account surplus countries; (ii) you need to hit exports, which the G7 cap does; (iii) enforcement of the G7 cap was terrible, which is mainly about poor EU governance... robinjbrooks.substack.com/p/lessons-fr...

Interesting perspective on sanctions, emphasizing the importance of enforcement. One point is the need for more resources for enforcement agencies. Investigative journalism is cool, but the authorities should be doing a lot of the work, in my view. www.nytimes.com/2025/08/24/b...

So important to have this kind of investigative journalism turning up what appear to be sanctions violations. on.ft.com/3UE7WZK

Really enjoyed this wide-ranging discussion by @natashasarin.bsky.social on @ezrakleinbot.bsky.social. What especially caught my eye was the mention of the tariff revenues (~$3T over 10 years) and what might replace them in a dem admin, including a carbon fee. www.youtube.com/watch?v=PI6R...

Disturbing to read the honorifics applied to Putin in these documents. "Luncheon in honor of his excellency Vladimir Putin."

Time for Graham & co to remember that they have 80+ votes in the Senate for tough sanctions.
