Hong Kong emission inventory for 2011 published

     The Environmental Protection Department (EPD) today (March 20) published the 2011 Emission Inventory for Hong Kong.

     Every year, the EPD compiles an emission inventory for five key air pollutants from different sources including power plants, vessels, motor vehicles, aviation and other fuel combustion sources. The five pollutants are sulphur dioxide (SO2), nitrogen oxides (NOx), respirable suspended particulates (RSP or PM10), volatile organic compounds (VOC) and carbon monoxide (CO).

     Hong Kong's total emissions in 2011 were 31 900 tonnes of SO2, 114 000 tonnes of NOx, 6 220 tonnes of RSP, 32 900 tonnes of VOC and 68 500 tonnes of CO. Compared with the emission levels in 2010, SO2 emissions fell by 10 per cent, mainly due to the full operation of the flue gas desulphurisation units retrofitted at coal-fired generation units. NOx emissions increased by 6 per cent mainly due to the increased use of coal for power generation to make up the shortfall in supply of natural gas and an increase in the tonnage of vessel arrivals. Emissions of RSP, VOC and CO in 2011 reduced by 1 to 2 per cent as compared with those in 2010.

     Details of the 2011 emission inventory and the 2011 emission report can be found on the EPD website: .
