Breaking: the @echr.coe.int just ruled in @greenpeace.de Nordic v. Norway — the first procedural #ClimateRights decision. States must now run science-based, timely, comprehensive EIAs before approving fossil projects ⚖️🌍

The kids who sued America over climate change aren’t done yet
They want an international human rights body to hold the U.S. accountable — and are spotlighting Indigenous communities on the frontlines.

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.”
