South Korea

Air pollution and South Korea research documents the air quality challenges facing this rapidly developed nation, including both domestic sources and transboundary pollution from neighbouring countries. Studies reveal high pollution levels in major cities that significantly impact public health, whilst highlighting innovative policy responses and technological solutions being developed. The evidence shows both the challenges of addressing pollution in a densely populated, industrialised country and the potential for coordinated regional approaches. Explore the research documenting South Korea's air quality situation and the lessons it offers for other developed nations.
  • South Korea has significantly improved air quality levels - dropped from 60 to 10 poor air days per year - 38% less PM2.5 since 2015 (Clean Air Fund, Feb 2025)
  • NO2 regulated under South Korea's Clean Air Conservation Act (POSTECH, 2025)
  • Ground monitors underestimated NO2 exposure by up to 11% in Gangwon-do and overestimated exposure by as much as 61% in Jeju-do (POSTECH, 2025)
