SHANGHAI: Air pollution levels fell in most cities in China last year, environmental group Greenpeace said on Wednesday, but a humid and windless winter shrouded swaths of the country in choking smog, slowing improvement in the second half.
Beijing hoisted its first ever "red alerts" on air pollution in December, when a blanket of humid, still air trapped haze over the capital. The episode followed heavy criticism of the government for inaction during a prior bout of hazardous smog.
"Despite Beijing's choking winter of red alerts, data from 2015 clearly shows a continued positive trend in Beijing and across the country," said Greenpeace climate and energy campaigner Dong Liansai.
"However, air quality across China is still a major health hazard."
Annual average levels of PM2.5 - particulate matter of 2.5 micrometers in diameter that can penetrate deep into the lungs - dropped by 10.3 per cent last year compared with 2014, Greenpeace said in a report published on Wednesday, citing official data from 189 cities.
