Beijing has reached an unprecedented environmental milestone, recording its cleanest air quality since monitoring began, according to the city’s annual government work report released Sunday. The remarkable achievement stems primarily from the massive adoption of new energy vehicles and comprehensive clean energy initiatives throughout the Chinese capital.
Mayor Yin Yong, presenting the report during the Beijing Municipal People’s Congress annual session, revealed that the city’s transformation toward ecological improvement reached new heights in 2025. The breakthrough came as Beijing’s fleet of new energy vehicles surpassed 1.3 million units, while renewable energy sources constituted 36% of the city’s power supply. For the first time in history, the city enjoyed good air quality on over 80% of days throughout the year.
The most significant indicator of this environmental progress emerged in the dramatic reduction of PM2.5 pollutants—dangerous fine particulate matter that poses serious health risks. Monitoring data showed the average annual concentration dropped to 27 micrograms per cubic meter in 2025, representing an 11.5% improvement over the previous year and the lowest level ever recorded.
Beijing’s manufacturing capacity for electric vehicles now stands at 700,000 units annually, creating a robust foundation for continued green transportation expansion. The city government announced ambitious infrastructure plans for 2026, including the installation of 30,000 new public charging stations to support the growing EV ecosystem and further accelerate the transition from fossil fuel vehicles.
