The Governments of the Hong Kong Special Administrative Region and Guangdong Province have teamed up to tackle the regional air pollution problem. Here you can learn about their initiatives, including the establishment of an air quality monitoring network throughout the Pearl River Delta.

Regional Air Quality Monitoring Network

Regional Air Quality Monitoring Network

The Environmental Protection Department of the Hong Kong Special Administrative Region and Guangdong Provincial Environmental Monitoring Centre established the Pearl River Delta Regional Air Quality Monitoring Network in 2005. In September 2014, the Environmental Protection Department and the Department of Environmental Protection of Guangdong Province enhanced the Network with the Macao Environmental Protection Bureau (Macao EPB) and the Macao Meteorological and Geophysical Bureau (Macao MGB) to release real-time air quality information for the Pearl River Delta (PRD) region. The enhanced Network has been renamed as the Guangdong-Hong Kong-Macao PRD Regional Air Quality Monitoring Network, with its geographical coverage increased from 16 to 23 automatic air quality monitoring stations in the Delta. Ten (10) stations are operated by the Environmental Protection Monitoring Centres of individual cities in Guangdong, eight are operated by the Guangdong Provincial Environmental Monitoring Centre and one, located in Macao, is operated by the Macao MGB. The remaining four are located in Hong Kong and operated by the Hong Kong Environmental Protection Department.

Goals of the Network

The Regional Air Quality Monitoring Network aims to:

  • Provide accurate data to help the two Governments appraise the air quality and pollution problems in the Pearl River Delta and devise appropriate control measures.
  • Evaluate the effectiveness of air pollution control through long-term monitoring.
  • Provide the public with information on the air quality of various places in the region.

 

Real-time Air Quality information

With a view to providing the public with more comprehensive real-time air quality information, the network releases the concentration levels of various air pollutants once an hour. Furthermore, the network provides the respective air quality indices of the three places: the Macao and Guangdong sides release their Air Quality Index once an hour and once every 24 hours, while the Hong Kong side releases the Air Quality Health Index once an hour. In addition, the network releases the annual report on the monitoring results and the pollution trend in the PRD region, and reports the quarterly statistical monitoring results.

Tackling Regional Air Pollution

To ensure that you can breathe cleaner air, and that your children will have a better quality of life, the Governments of the Hong Kong Special Administrative Region and Guangdong Province have been involved in a number of anti-pollution initiatives. As part of the agreement that established the Regional Air Quality Monitoring Network, the two governments have worked individually various measures, including:

Hong Kong

  • Vehicle emission control, including encouragement to use pollution control devices on private vehicles and the conversion of mini-buses to liquefied petroleum gas instead of diesel fuel.
  •  Power station emission control, including the use of air-scrubbing equipment and placing emission limits on individual stations.

Guangdong

  • Vehicle emission control, including further tightening motor vehicle emissions and fuel standards, and recovering vapour from oil depots, tanker trucks and petrol filling stations.
  • Other emission control, including improving energy supply structure, installing flue gas desulphurisation systems in thermal power plants, and stepping up control of emissions from industrial sources.
