Eleven chemical plants in China and one in the U.S. emit a climate super-pollutant called nitrous oxide that’s 273 times more potent than carbon dioxide

Proven, low-cost pollution controls could quickly curb those emissions, but neither China nor the U.S. require abatement measures used by other plants around the world.
