UN General Assembly Passes Landmark Climate Resolution Despite Opposition from US, Russia, and Iran

The UN General Assembly has passed a landmark, non-binding resolution backing a court opinion that countries have a legal duty to fight climate change. The resolution, which passed 141-8, was opposed by major oil producers including the US, Russia, and Iran. Led by the island nation of Vanuatu, the measure urges a transition from fossil fuels and is expected to boost climate litigation worldwide.
