New Zealand’s Greenhouse Gas Inventory (the inventory) is the official annual report of all anthropogenic (human-induced) emissions and removals of greenhouse gases (GHG) in New Zealand. It measures New Zealand’s progress against obligations under the United Nations Framework Convention on Climate Change (the Convention) and the Kyoto Protocol and is the official basis for measuring New Zealand’s progress towards its international emissions reduction targets.

The inventory submission consists of the common reporting format (CRF) database containing inventory data for 1990–2017 from all emissions and removals in New Zealand together with this publication, the national inventory report, which is a narrative that presents major emission trends and methodologies for estimating emissions and removals. It also includes sections on the inventory uncertainties, recalculations and improvements.

Inventory reporting under the Convention covers seven direct GHGs: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3).1 Indirect GHGs2 are also included; however, only emissions and removals of the direct GHGs are included in estimates of total national emissions under the Convention and accounted for under the Kyoto Protocol.

The gases are reported under five sectors: Energy; Industrial Processes and Product Use (IPPU); Agriculture; Land Use, Land-Use Change and Forestry (LULUCF); and Waste.

New Zealand ratified the Convention on 16 September 1993 and the Paris Agreement on 4 October 2016. The extension (as of 13 November 2017) of New Zealand’s ratification of the Convention and the Paris Agreement to include Tokelau means, inter alia, that New Zealand’s national inventory shall include GHG emissions and removals estimates from Tokelau. For the first time, emissions from Tokelau are included in New Zealand’s greenhouse inventory.
