Government says it can meet 2030 emissions budget, despite watchdog warning

The Government says it has improved confidence it can stay within its greenhouse gas budgets, despite a July warning from the Climate Change Commission that all climate targets were at risk.

The claim came in its formal response to the Commission's annual emissions monitoring report, published by the Ministry for Cities, Environment, Regions and Transport. The Government said it acknowledged the Commission's recommendations, according to RNZ. It said delivery confidence had improved because of policy decisions taken since the Commission's assessment period ended on 31 March.

On the ministry's numbers, New Zealand is on track to meet its current emissions budget ending in 2030 with a buffer of 3.6 million tonnes. That buffer is about 1.2 per cent of the overall budget. The ministry confirmed the next emissions budget, the third budget running from 2031 to 2035, is off track by 8.7 million tonnes.

Emissions budgets work like a household spending cap, but for pollution. They set the maximum the country can emit in a five-year period to stay on track for 2050. Each budget period must have an emissions reduction plan. The second emissions reduction plan covers 2026-30 and states confidence its actions will meet the second budget.

The Commission's July report had taken a different view. It said climate pollution had gradually decreased over time but progress stalled in 2024. It said the 2050 net-zero target and emissions budgets might not be met without new policies to cut pollution. It singled out the Government's decision to axe agricultural emissions pricing. It described confidence in the emissions trading scheme, the market where emitters buy and sell carbon units, as "fragile".

The Government pointed to four developments since 31 March. They include an additional $51m investment fund to encourage farmers to adopt emissions-reducing technologies, and a new Gas Transition Loan Guarantee Scheme to help major gas users convert to other fuel types. The list also cites a $21m second round of zero-interest loans for public EV chargers, and the decision to keep the Clean Vehicle Standard, which limits tailpipe emissions of imported vehicles.

The statutory targets behind those budgets remain unchanged. The legislated target is net zero greenhouse gas emissions, except biogenic methane, by 2050, with biogenic methane, largely from livestock, to be reduced by 10 per cent below 2017 levels by 2030. The updated Nationally Determined Contribution is a target to reduce net emissions by 50 per cent below gross 2005 levels by 2030, according to the Beehive.

There is technical context around the headline buffer. Changes to the Greenhouse Gas Inventory since a budget was set mean that budget can now be met with less effort than originally required, the Commission has noted. The first emissions budget covers 2022-2025. The Government's separate near-term accountability sits under Government Target 9, to reduce net greenhouse gas emissions to no more than 290 megatonnes total net emissions from 2022 to 2025, with quarterly reporting published by the Ministry for the Environment. Treasury's Budget 2026 Information Release includes documents relating to the Climate Change portfolio.

The broader context here is how thin the margin is. A 3.6 million tonne buffer leaves little room for under-delivery, fuel switching delays or ETS price weakness, while an 8.7 million tonne gap in the 2030s points to policy work still to be specified in detail. Ministers can argue second budget compliance is now central-case, but the Commission's language on second budget risk has hardened from significant risks to at increasing risk in its 2026 monitoring report, according to the Climate Change Commission. Its 2025 monitoring report had said it is possible to meet the third budget and the 2050 target and to reduce risk for the second budget. Delivery, not target-setting, is now the test.

The next formal check is already scheduled. The next emissions reduction monitoring report is due by 15 July 2026. The first emissions reduction plan was formally amended in December 2024. What officials report between now and July, through the Target 9 quarterly series and ETS auction results, will determine whether the Government's confidence call holds.
