This section sets out the strategies of the Hong Kong SAR Government (HKSARG) for tackling air pollution problems.
Hong Kong has been facing two air pollution issues. One is local street-level pollution. The other is the regional smog problem. Diesel vehicles are the main source of street-level pollution. Smog, however, is caused by a combination of pollutants from motor vehicles, marine vessels, industry and power plants both in Hong Kong and in the Pearl River Delta (PRD) region.
