Hong Kong's pollution problem

Air pollution in Hong Kong is causing 3,000 premature deaths a year in the territory and starting to affect businesses, say campaigners.

Air pollution in China has been making news headlines much of this week, and it is a problem shared with Hong Kong which is now seeing its impact on businesses.

Campaigners say some 3,000 people prematurely die from poor air quality a year.

The territory's leader, CY Leung, has announced a $1.3bn (£810m; 977m euros) subsidy programme to help phase out heavy polluting vehicles.
