1. The footnotes to Table 5.13 also apply to this table, including revision of the figures; though note that emisions of methane and nitrous oxide from road transport are estimated using vehicle kilometre data in both of the calculation methods, and the total emissions of these GHGs from the two methods are identical. There are no emissions of other greenhouse gases by Transport in the Inventory.
2. The figures for greenhouse gas emissions are expressed in terms of their Global Warming Potential in tonnes of carbon dioxide equivalent. To convert from tonnes of carbon dioxide equivalent to tonnes of other gases multiply by the following factors: methane - 1/21, nitrous oxide - 1/310.
