Taranaki records largest decrease in regional greenhouse gas emissions in 2025 – news story
21 August 2026
Taranaki region had the largest decrease in greenhouse gas emissions in the year ended December 2025, according to figures released by Stats NZ today.
Overall, New Zealand’s total regional greenhouse gas emissions decreased 1,921 kilotonnes to 76,202 kilotonnes in the year ended December 2025, the lowest level since the series began in 2007.
“For the second year in a row, Taranaki had the largest decrease in greenhouse gas emissions,” environment statistics spokesperson Tehseen Islam said.
Taranaki’s total emissions decreased 657 kilotonnes (12.4 percent) between 2024 and 2025. The region accounted for 34 percent of the overall reduction in regional emissions in that period.
“The 12.4 percent fall in emissions in the Taranaki region was largely driven by lower emissions in the electricity, gas, water, and waste services industry (down 279 kilotonnes) in 2025. This follows an 8.2 percent decrease in the region’s emissions the previous year,” Islam said.
