Air pollution levels in Beijing fell significantly in the first quarter of 2015 compared to the same period last year, according to environmental campaign group Greenpeace.
However, the capital city still ranks among the worst polluted Chinese cities and the air quality continues to pose a threat to public health, it said.
PM2.5 concentrations in Beijing were down 13 percent in the first quarter compared to the corresponding period in 2014, Greenpeace said, according to Ming Pao Daily.
PM2.5 refers to fine particulate matter with diameter of 2.5 micrometers or less.
The data was compiled based on figures from 360 Chinese cities released by China’s Ministry of Environmental Protection.
PM2.5 concentrations in industry-heavy Hebei province improved 31 percent in the first quarter, according to the Greenpeace report.
However, China’s overall air quality situation remains severe as 90 percent of the cities still record levels of pollution that far exceed the country’s own air quality standards, the environmental group said.
It noted that PM2.5 concentrations in inland provinces like Henan, Hubei, Hunan and Sichuan are on rise as local governments have not rolled out strict measures to control pollution.
