According to a paper recently published in Atmospheric Chemistry and Physics global air quality will be the same in 2050 as that currently inhaled by the average Beijinger if man-made emissions remain at current levels and air quality legislation is not reinforced.

Blue sky over the Forbidden City
Environment authorities in Beijing will no longer use the method of counting "blue sky days" as a gauge of air quality, which had been practiced for more than a decade. The city launched the "Defending the Blue Sky" project in 1998, when it had only 100 days of "blue skies." Beijing has used a five-grade classification of air quality on the basis of pollution indices, with grade I being the best and grade V the worst. Days with grade I or II air quality are considered "blue sky days."
The quality of environment around New Delhi has worsened and its air pollution and congestion crisis will worsen this decade if urgent steps were not taken to address it, two leading green NGOs have warned.
Shanghai's hazy outlook
June 04, 2012
Having clearly learned nothing from the public embarrassment of their colleagues in Beijing last year, Shanghai's Environmental Protection Bureau has branded publication of local air quality data by the US consulate in Shanghai  illegal. At a press conference on Friday bureau director Zhang Quan said the consulate cannot legally reveal data it collects in PM2.5 tests, which measure the concentration of particulate matter of 2.5 microns or less in diameter. "There are certain criteria that must be met if these data are to be published officially," Zhang said. "A city needs at least eight to ten monitoring stations in various spots, depending on its size, to measure PM2.5. An analysis of a city's air quality cannot be done using readings from a single machine."
