Seasonally adjusted industry and household greenhouse gas (GHG) emissions in Aotearoa New Zealand decreased 1.1 percent (209 kilotonnes) in the September 2025 quarter, according to figures released by Stats NZ today.

“Emissions this quarter were the lowest recorded since the start of our time series in 2010, and the decline this quarter was driven mainly by electricity generation,” environment statistics spokesperson Tehseen Islam said.

In the September 2025 quarter, industry emissions (excluding households) decreased by 1.3 percent (229 kilotonnes). In comparison, gross domestic product (GDP) increased 1.1 percent in the same period.

Total household emissions fell 0.6 percent (13 kilotonnes), largely driven by a 0.8 percent (14 kilotonnes) decrease in household transport emissions in the September 2025 quarter.
