Not all cities under UN-backed pilot effort see improvements

Some of the mainland's most polluted cities have cleaned up their act over the past few years with the help of a joint UN-central government programme, but others are still choking under a contaminated shroud.

Eighteen cities across the country were enlisted four years ago as pilot centres for the Clean Energy Action project, a US$3.19 million initiative funded by the United Nations Development Programme and the central government, said a report released in Beijing yesterday.

The project aimed to help the cities reduce air pollution by adopting cleaner energy technology or switching to greener power sources.

Most cities in the programme registered a 40 per cent increase in the number of days in a year with very little pollution compared with five years ago.

More than half had improved air quality by reducing sulfur dioxide and total suspended particulate levels by 10 per cent to 30 per cent.
