“0.1 Microgram” Initiative

This is an initiative that builds upon Beijing’s earlier “One Microgram” campaign. It reflects the city’s ongoing commitment to air pollution control in the face of new challenges, such as diminishing room for additional emission reductions, increasing difficulty in making further improvements, slower declines in pollutant levels, and recurring short-term fluctuations. By emphasizing the importance of reducing fine particulate matter concentration by every 0.1 microgram, this initiative represents a more science-based, targeted, and meticulous approach to achieving air quality improvements.
