GHG emissions inventory covers seven types of GHGs specified in the Kyoto Protocol. The global warming potential rates were from the IPCC Fifth
Assessment Report (2014).
1. “Non-hazardous waste landfilled” refers to the refuse, wood pallets and construction waste collected from Towngas Headquarters and the Tai Po Gas Regional grid emission factors were used for GHG emissions due to electricity consumption, while other emission factors were obtained from local

2. “Non-hazardous waste recycled” refers to the plastics, papers, paper cartons and metals collected and delivered to recycling contractors. Apart from these 5. Scope 1 emissions – Direct emissions including fuel consumption of production plants, vehicle fleets etc.
waste categories, we also recycle other non-hazardous waste, such as used red packets and cartridges, on a regular basis. Scope 1 GHG emissions were adjusted to reflect the biogenic nature of landfill gas and its associated carbon emissions during use.
