Estonia tops 2026 Environmental Performance Index as UK ranks third and US places 27th

The 2026 Environmental Performance Index from Yale and Columbia ranks Estonia as the world's most sustainable country. Estonia cut emissions 40% by retiring old oil shale power plants. European nations dominate the top 15 spots. The UK ranks third, while the US sits at 27th. China ranks 129th due to heavy coal reliance. India and Bangladesh are near the bottom. The EPI scores 177 countries on 47 metrics including climate change, air quality, and ecosystem vitality. Researchers warn that even top performers fall short on critical sustainability challenges. Analysts note that Estonia's big emissions cut came from a one-time plant closure, and deeper reductions will require harder work. Critics argue the rankings oversimplify global environmental issues. No single country can solve climate change alone. But the index provides a useful snapshot of which nations are making progress and where gaps remain.
