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 2021 inventory contains the emissions and removals data from 1990 to 2019, major emissions trends, and methodology used by New Zealand for estimating its emissions and removals. The inventory informs the Ministry for the Environment’s policy recommendations on climate change, and it enables them to monitor progress towards New Zealand's emissions reductions targets.
