GHG emissions include four of the seven greenhouse gases covered by the Kyoto Protocol – carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), nitrogen trifluoride (NF3) and sulphur hexafluoride (SF6) emissions have been omitted from our Scope 2 reporting, as we do not generate material quantities of these greenhouse gases.
