Is China Emitting a Climate Super Pollutant in Violation of an International Environmental Agreement?
Concentrations of HFC-23, one of the world’s most potent greenhouse gases, remained elevated in East Asia after China, a known past polluter, agreed to curb emissions.
Preliminary atmospheric monitoring data from a remote South Korean island off China’s east coast shows elevated concentrations of hydrofluorocarbon-23 (HFC-23), a greenhouse gas 14,700 times more potent than carbon dioxide on a pound-for-pound basis, according to the World Meteorological Association.
