New Zealand's total and net greenhouse gas emissions
1990–2017, kilotonnes of CO2 equivalent
LULUCF: Land use, land-use change and forestry. A greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use, land-use change and forestry activities.
CO2: carbon dioxide
N2O: nitrous oxide
SF6: sulphur hexafluoride
For more information
The inventory reports greenhouse gas emissions and removals from five sectors:
- energy (eg, emissions from transport and electricity generation)
- industrial processes and product use (IPPU) (eg, cement production and refrigeration)
- land use, land-use change and forestry (LULUCF)
The most recent inventory report covered the following direct greenhouse gases:
carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6).
Only emissions and removals of these six direct greenhouse gases are included in the national greenhouse gas total.
The inventory also reports indirect greenhouse gases but they are not included in New Zealand’s greenhouse gas total. These gases do not have a direct warming effect, but react with other gases in the atmosphere and increase the concentration of greenhouse gases.
The indirect gases are: oxides of nitrogen (NOx), sulphur dioxide (SO2), carbon monoxide (CO), non-methane volatile organic compounds (NMVOCs).
Changes to data collection/processing
The continuous improvement of inventory development and reporting is a fundamental requirement under the Kyoto Protocol and the UNFCCC. When inventory improvements are made, it is good practice to recalculate the entire time series to ensure the consistency of emission trends. Recalculated estimates can result from any one improvement or a combination of improvements in activity data, emission factors, methodology or when additional emission sources are identified.
In 2017, for the first time, emissions from Tokelau are included in New Zealand’s greenhouse gas inventory. In 2017, emissions from Tokelau were 0.004% of New Zealand’s gross emissions.

About this dataset
New Zealand’s Greenhouse Gas Inventory is the official annual report of all anthropogenic (human induced) emissions and removals of greenhouse gases in New Zealand. The inventory measures New Zealand’s progress against obligations under the United Nations Framework Convention on Climate Change and the Kyoto Protocol.
