Residents of Beijing are enjoying unusually clear skies this winter as officials indicated that measures to tackle the city’s notorious pollution problem appear to be having some effect.

However, experts cautioned that the improvement was still fragile and said there was a risk the problem could recur.

Thanks to improving conditions, the average reading of PM2.5 – particle matter less than 2.5 micrometers in diameter – fell by 54 per cent in November compared with the previous year to 46 microgrammes per cubic metre.

The city’s environmental protection bureau, which compiles the data, said this was the lowest November total for five years.

The reading stood at 38 microgrammes per cubic meter since the city officially turned on the heating for the winter on November 15, compared with an average of 93 in the previous four years, the official news agency Xinhua reported.
