(ECNS) -- China's capital is mulling long-term plans to reduce PM2.5 density to the national standard at 35 micrograms per cubic meter of air on average a year by 2030, said Fang Li, deputy director of Beijing Environmental Protection Bureau.
At a press conference on the city's air quality in 2015, Fang said the plan would be introduced by the end of this year or early next year.
Fang also said Beijing recorded a PM2.5 density of 80.6 micrograms per cubic meter of air on average in 2015, a drop of 6.2 percent from 2014 but still 1.3 times higher than the national standard.
The city has previously pledged to reduce PM2.5 density by 25 percent or more by 2017 with the implementation of a five-year action plan.
PM2.5 is a measurement of airborne particles less than 2.5 microns in diameter, which can pose health risks.
