Global mercury emissions have fallen 70% since the 1980s
Mercury pollution has dropped 70% since 1982, marking one of the most significant environmental reversals in recorded history. Researchers confirmed the decline by analyzing mercury levels trapped in alpine plant leaves collected from the Tibetan Plateau near Mount Everest, revealing a clear link to global policy action and the worldwide shift away from coal. The UN’s Minamata Convention, adopted in 2013, and stricter emissions standards — including US regulations that cut American power plant emissions by roughly 90% — drove much of the progress. The achievement demonstrates that sustained international cooperation can reverse even deeply entrenched industrial pollution.
