Greenhouse gas emissions (industry and household): Year ended 2018

Greenhouse gas emissions (industry and household): Year ended 2018

This release includes estimates for 114 industries, up from 21 industries last year, and households and tourism as a cross-cutting industry. The additional detail gives a fuller picture of the industrial sources of New Zealand's emissions profile. For more information on greenhouse gas emissions from industries and households in 2018 see the associated excel tables and CSV files in Greenhouse gas emissions (industry and household): Year ended 2018.

Emissions are expressed in carbon dioxide equivalents, which are the emissions of greenhouse gases weighted by their 100-year global warming potential. Economic activity is measured as chain-volume value added. Average annual changes relate to the 2007-18 period.

The release shows the production of greenhouse gases on a standard industrial classification basis and is designed to enable emissions data to be compared to economic statistics, such as GDP or employment.

Stats NZ data includes emissions from resident New Zealand industries and households, regardless of where the emission occurs, while the Ministry for the Environment’s data in New Zealand's Greenhouse Gas Inventory records emissions on the domestic territory only. Therefore the estimates of carbon dioxide equivalents in Greenhouse gas emissions (industry and household): Year ended 2018 is 2,493 kilotonnes higher in 2018 than the Greenhouse Gas Inventory. This is mainly due to the deduction of 609 kilotonnes for non-residents in New Zealand and addition of 3,106 kilotonnes for the activities of New Zealanders operating overseas.
