The second paper, with Carola Klöck, explores to what extent countries use strategies such as sending more senior negotiators, maintaining delegations continuity, or sending non-governmental experts to compensate for small delegation size in #UNFCCC negotiations.

As 2025 draws to a close, I am happy to share two papers on the #UNFCCC climate change negotiations. In the 1st one, #open_access in Nature Scientific Data, we present an algorithm to retrieve data on parties’ participation and bargaining interactions in the negotiations, drawing from @enb.iisd.org.

10 years after the adoption of the #ParisAgreement, Nature Climate Change has published a reflection of what has been achieved and what still needs to be done. I’m honoured to have contributed the section on countries’ nationally determined contributions (#NDCs). Full text here: rdcu.be/eOpVp

🔥 ⚖️ 🌐HAPPENING NOW: Historic #ClimateJustice Ruling being delivered by the 🇺🇳 🧑‍⚖️ International Court of Justice. 🚨This ruling could signal a new dawn for climate law & accountability 📝 🧵 Live thread below with context, summary & analysis 👇 #ClimateJusticeAO #AOLetsGo

"IHRL, the climate change treaties, and other relevant environmental treaties...inform each other. States must, therefore, take their obligations under IHRL into account when implementing their obligations" Good to see IHRL coming out strongly as we go through the opinion

Ahead of today's ICJ #ClimateChange #AdvisoryOpinion, I've seen a lot of "but it won't be binding." This is, like a lot of things, technically true and also beyond the point. 🧵 #IntLaw

"The ICJ pointing the direction for the entire world and making clear that every nation is legally obliged to solve the climate crisis," says PIK director Johan Rockström in @rfi.fr. 1.5°C would now be recognised in international law as planetary limit. www.rfi.fr/en/internati...

World's top court paves way for climate reparations

The world's highest court Wednesday declared that states are obliged under international law to tackle climate change and warned that failing to do so could open the door to reparations.

70% of all fossil fuel emissions ever, occurred in my lifetime🤯

David Ho@davidho.bsky.social · last yr.

If you think climate change has gotten worse during your lifetime, you're right and there's a good reason. If you're Gen X like me, more than 3/4 of fossil fuel CO₂ emissions have occurred in your lifetime. Even if you're a Millennial, it's at least half. 📊: @neilrkaye.bsky.social

How can we assess the implementation gap existing between climate change #mitigation pledges under the #ParisAgreement and national policy-making? In our just published Climate Policy article, we use a public policy approach to develop two Vertical Policy Harmonization indices that do just that.

Just at the end of 2024 we finally published our DeCIRRA report on “Future use of Carbon Management to achieve Emissions Reductions and Removals in Switzerland: Scenario and Modeling Analysis“. (decirra.ch/publikationen/).
