1. The following conversion factors are used to standardise the units to gigajoules (GJ): Town gas (0.048GJ/unit), electricity (0.0036GJ/kWh), petrol (0.033GJ/
L), diesel (0.036GJ/L). The conversion of naphtha and landfill gas to energy is calculated by multiplying individual monthly fuel volumetric data by their
corresponding monthly average calorific value.
2. Tankers and ECO Aviation Fuel Services (EAFS) vehicles are excluded.
3. GHG inventory covers seven types of GHGs specified in the Kyoto Protocol. The global warming potential rates were from the IPCC Fifth Assessment Report
(2014).
Emission factors of GHG emissions due to electricity consumption are obtained from two local electricity companies, while other emission factors were
obtained from local governments and authorities, or other recognised sources.
1. From 2018, the figures included all training sessions conducted by internal departments and external organisations. Prior to 2018, the figures included training Scope 1 GHG emissions were adjusted to reflect the biogenic nature of landfill gas and its associated carbon emissions during use.
sessions mainly conducted by the Corporate Human Resources Department and Towngas Engineering Academy, while other training hours, such as HSE and 4. All water is freshwater purchased and distributed by the HKSAR Water Supplies Department. All wastewater handling procedures comply with the local
its related CPD, were reported separately. regulations.
