These graphs and tables summarise the data from New Zealand’s Greenhouse Gas Inventory.

New Zealand’s Greenhouse Gas Inventory is the official annual report of human-generated greenhouse gas emissions in New Zealand. This tool shows the data from the latest inventory report. For a summary see the 1990-2018 Snapshot.

The Inventory reports on six sectors which are groupings of related processes, sources and sinks of greenhouse gases:

Energy – (eg, road transport and electricity production)

Industrial Processes and Product Use (IPPU) – (eg, metals, minerals and chemicals)

Agriculture – (eg, nitrous oxide from fertiliser, methane from livestock digestive systems and manure)

Waste – (eg, solid waste and wastewater)

Land Use, Land-Use Change and Forestry (LULUCF) – (eg, forest land, cropland, grassland, wetlands, settlements, other land).

Tokelau – (eg, Energy, IPPU, Agriculture and Waste for Tokelau, New Zealand's overseas dependent territory).

Gross emissions comprise greenhouse gas emissions from all sectors excluding LULUCF. Net emissions comprise greenhouse gas emissions and removals from all sectors including LULUCF.

Net emissions are lower than gross emissions because the LULUCF sector currently removes more greenhouse gas from the atmosphere than it emits.

Emissions from Tokelau were included in New Zealand’s gross emissions for the first time in 2019. They are reported in the ‘Tokelau’ sector, separately from the remaining sectors.

Note: Emissions or removals of less than 0.005 kt CO₂-e may not always be displayed in the tables as they are rounded to 2 d.p.

Please note this information contains only historical greenhouse gas emissions from 1990 to the latest reported year. The latest reported year is approximately 15 months behind the inventory publication to give time for countries to collect data.
