When Custom Binds All States 🌍⚖️

MARKUS GEHRING (@mwgehring.bsky.social) on the International Court of Justice's trailblazing findings on customary international law as it applies to climate change.

Quote: “The ICJ clarifies that rejecting or breaking the existing international treaty regime on climate change does not diminish any State’s obligations to actually address the underlying global challenge that is climate change.”

Excited to share new work with Cristian Heredia Ligorria and Cara Schulte! ✨ Our report reviews 78 climate laws in the Caribbean, showing how the region is advancing resilience, climate finance, and rights-based approaches — despite its vulnerability to climate change.

💡According to the Sabin Center’s Maria Antonia Tigre (@matigre.bsky.social), the ICJ’s decision will likely “create [a] new wave of climate litigation.” Read reporting from @NPR.org: buff.ly/ifwfLGV

"A Single Paragraph’s Promise"

LENA RIEMER on the International Court of Justice's advisory opinion on climate change and the understated question of climate-induced human displacement.

Quote: “This one seemingly modest paragraph may have profound implications for millions of people fleeing across borders due to climate change, potentially reshaping the legal landscape for those seeking protection and at least offering minimum guarantees against their removal to a place where they would be at risk.”

The UK gov has just published new guidance for environmental impact assessments for oil & gas projects. Despite reports/industry spin, it includes a genuinely robust, credible approach to assessing the emissions caused by burning oil & gas. Let's take a look! 🧵

Rosebank & Jackdaw fields face 'tightened' approval process
Last year, the Supreme Court ruled that firms must account for emissions created by the burning of fossil fuels.

Key questions before the court:
🌍 Is there a serious threat to Lliuya’s property?
💨 How much did RWE’s CO₂ emissions contribute?

Lliuya, a Peruvian farmer and mountain guide, argues that Europe’s biggest emitter should pay its share of damages for the glacier melt threatening his home. In 2022, German judges even traveled to Peru to assess the risk—a rare step in climate litigation.
