Hong Kong's Emissions


Hong Kong's Emissions

The graph below shows the greenhouse gas emission levels from 1990-2012. As of 2012, Electricity Generation accounted for 68.2% of total greenhouse gas emissions in Hong Kong, followed by Transport contributing 17.1%. Buildings account for 90% of the total GHG emission from Electricity Generation i.e. they account for 61% of the total GHG emission.  Other minor emission sources include waste treatment, industrial processes and agriculture, forestry and other land use.

Hong Kong’s per capita level of CO2 emissions are now at 6.0 tonnes of carbon dioxide equivalent per capita in 2008. In 1990 GHG emissions totalled 35,300 kilotonnes CO2-equivalent (CO2-e). By 2008 this had grown to 42,000 kilotonnes CO2-e.


Hong Kong's per capita emissions compare favorably to other developed economies due to our diverse fuel mix for electricity production, our excellent use of public transportation, and limited manufacturing activities. Hong Kong is a small emitter of GHG accounting for less than 0.2% of the world's total of direct emissions. Among HK's GHG emissions, about 85% of the total Global Warming Potential (GWP) weighted GHG emissions in Hong Kong were CO2, about 12% were methane (CH4), with the remainder 3% is from Nitrous oxide ( N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6). However, these figures do not take into account the manufacturing and agricultural activities outside of Hong Kong that our economy depends on. Neither do they consider carbon emissions of international airlines and shipping.
