The International Court of Justice (ICJ)’s recent advisory opinion on climate change represents a pivotal moment in the evolution of international climate law. By affirming that States can incur legal responsibility for failing to reduce greenhouse gas (GHG) emissions, the ICJ brought long-standing principles of State responsibility into sharper focus […]
The International Court of Justice (ICJ)’s release of its Advisory Opinion on the Obligations of States with Respect to Climate Change marks a watershed moment, not just because of what the court says about climate obligations, but also because of how it says it.

The climate footprint of the first fifteen months of Israel’s […]
The climate crisis has necessitated a wave of bold innovation. As new climate mitigation strategies have been developed, the law has often failed to keep up. This is especially clear in the ocean, where marine carbon dioxide removal (mCDR) projects – techniques that use the ocean to remove and store […]
