Climate, energy and environment / Climate commitments
What should New Zealand's climate commitments be?
New Zealand has a Paris pledge and 2050 targets in law. Parties differ on keeping them.Under the Paris Agreement, New Zealand has pledged to halve net emissions by 2030 and to cut them 51 to 55% below 2005 levels by 2035. The Zero Carbon Act sets a 2050 target of net zero for most gases, and a separate target for methane from farm animals and waste, lowered in 2025 to 14 to 24% below 2017 levels. The Climate Change Commission advises on these targets and checks progress; in July 2026 it said current plans were not enough to meet later budgets or the 2050 target. The Emissions Trading Scheme (ETS) puts a price on most emissions but not on farming. Treasury estimates meeting the 2030 pledge could mean buying about $4.4 to $5 billion of overseas credits. Parties propose leaving Paris, keeping current settings, or tightening targets and the ETS.
Uneven evidence. Some parties' plans have more published costings or analysis than others. Read what was found
As at 15 October 2026, Treasury's estimate of offshore mitigation costs is the only published costing that bears on these plans, and it applies to staying in Paris and meeting the 2030 pledge. No independent costing was found for leaving Paris, ACT's trade-weighted emissions cap and refund of ETS revenue, abolishing the Commission, Labour's ETS review, or the Green and Opportunity plans to price farm emissions. The Commission's 2026 report assesses current policy, not any party's plan. NZ First's figure of "up to $22 billion" going offshore could not be traced to a published source, and ACT gives no source for its household cost, Commission cost or 2.2% GDP figures. Te Pāti Māori's full climate policy, read on 17 October 2026, sets out no position on the questions compared here. Evidence sections reflect what has been published, not a judgement on the plans.

Each party's whole answer, under the same headings for every party.
ACT
Repeal the net zero target, close the Climate Commission, and refund carbon auction money.ACT would repeal the Zero Carbon Act and its 2050 net zero target, and tie New Zealand's emissions cap to a trade-weighted average of its major trading partners. It would remove the minimum price at Emissions Trading Scheme (ETS) auctions and refund all net auction revenue to households; ACT says the ETS costs an average household about $478 a year. It would close the Climate Change Commission, saving what ACT puts at $14 to 15 million a year, and move its monitoring to a ministry. It opposes new climate taxes, including a tax on agricultural emissions. It would renegotiate the Paris commitment and says New Zealand "should be prepared to leave" if that fails. The biggest tradeoff: no auction floor and auction revenue returned to households, but trade risk if New Zealand leaves Paris and, if the carbon price falls, less price pressure on emitters to cut emissions.

Farm emissions

Green
A Budget tied to 1.5°C and gross targets, a farm emissions price, a tighter ETS.The Greens would strengthen the Zero Carbon Act so the government Budget process must be consistent with limiting warming to 1.5°C, gross emissions reduction targets (before forests are counted) and international commitments. The Climate Change Commission would set the number of units in the Emissions Trading Scheme (ETS). Free units for industry would be phased out and forestry offsets removed, with ETS money going to a fund to cut industrial emissions. Farm emissions would be priced to meet the methane targets, with support for farmers. The Greens would meet the Paris pledges at home and, if needed, through projects overseas, and show the pledge's cost in the government's accounts. No costs or start dates are given. The biggest tradeoff: a cap on gross emissions with farming priced, but new costs for farmers and for industries that lose free units.

Labour
Stay in Paris, review the ETS, and no farm emissions price by default.Labour says it is "fully committed" to the Paris Agreement and would put New Zealand "on course" to meet its targets. It says it would "urgently review" the Emissions Trading Scheme (ETS), which it says is "broken" because the carbon price is too low. Labour says the review would favour "genuine emissions reductions" over offsets, reconsider forestry's place in the scheme, write rules to stop whole farms being converted to forestry, and make sure the ETS supports the Paris targets. New forestry registrations would be paused during the review. Labour would not price farm emissions by default; Chris Hipkins has said pricing is "not ruled out for all time". No cost or timetable is given. The biggest tradeoff: an ETS geared to direct cuts with no default farm price, but the effect on household and business costs depends on a carbon price Labour has not set.

Stay in Paris, keep net zero 2050 and the lower methane target, no farm price.National would keep New Zealand in the Paris Agreement, which Christopher Luxon has made a bottom line in coalition talks. It would keep the 2050 net zero target and the methane target it set in 2025 (a 14 to 24% cut below 2017 levels by 2050, reviewed in 2040). Farm emissions would not be priced; National relies on technology and says over $400 million is being invested with industry. Luxon says the government will "do everything we can" on the 2030 pledge but is not "sending billions of dollars offshore" for credits. National has not said it would change the Climate Change Commission; in 2025 the government said the Commission would no longer have to evaluate emissions reduction plans. The biggest tradeoff: no new cost on farmers and no stated plan to buy overseas credits, but government estimates put the 2030 methane cut at 7.9%, short of the 10% target.

NZ First
Withdraw New Zealand from the Paris Agreement and review the Climate Change Commission.NZ First would take New Zealand out of the Paris Agreement "altogether". It argues that New Zealand produces about 0.17% of global emissions, that four countries produce about 60% of the world's carbon dioxide, and that money spent meeting Paris pledges would be better spent on the environment at home. It says that if New Zealand honours its Paris obligations, "up to $22 billion" of taxpayers' money could go offshore. NZ First has also said it would review the Climate Change Commission. Its policy does not say what would happen to the Zero Carbon Act targets, the Emissions Trading Scheme or farm emissions, and gives no start date. The biggest tradeoff: no overseas credit costs or Paris obligations, but trade risk under the EU agreement's Paris clause.

Recommit to Paris, follow Climate Commission advice, and cap-and-trade for farm methane.Opportunity makes recommitting to the Paris Agreement and protecting the Climate Change Commission's role one of its five bottom lines for any coalition. It would "restore the integrity" of the Paris pledge and follow the Commission's advice on meeting the 2050 targets. It proposes a cap-and-trade scheme for farm methane and nitrous oxide, and changes to Emissions Trading Scheme (ETS) pricing and forestry rules; news reports say it would also give the Commission power over ETS price controls and budgets. It would set up a $5 billion Climate Resilience Fund and a $1 billion fund, backed by ETS revenue, to move industry off coal and gas. No start dates are given. The biggest tradeoff: a cap on farm methane and nitrous oxide and new climate funds, but new costs for farmers and emitters.

Background and sources
The commitments now. New Zealand's first Paris pledge (its nationally determined contribution, or NDC) is to halve net greenhouse gas emissions by 2030, and its second, lodged in January 2025, is a 51 to 55% cut below 2005 levels by 2035 (Ministry for the Environment; ODT/RNZ). The Zero Carbon Act's 2050 target is net zero for all gases except biogenic methane. A December 2025 law change cut the 2050 biogenic methane range from 24 to 47% to 14 to 24% below 2017 levels, required a review of that target by the end of 2040, and removed the requirement for ETS limits and price controls to reflect the NDC (New Zealand Legislation; ODT/RNZ). In November 2025 the government also announced the Commission would no longer have to evaluate its emissions reduction plans (The Spinoff).
Progress. The Climate Change Commission's 2026 monitoring report (22 July 2026) said the Government's projections show the second emissions budget (2026–2030) is likely to be met by 3.6 Mt, but more than half of the planned reductions (12.4 Mt) are "at significant risk". Government estimates show the 2030 methane target would be missed (a 7.9% cut against 10%). The Commission said the country "needs to more than double the current pace of decarbonisation", and expected the ETS to be unable to drive further cuts from about 2034 without changes (Climate Change Commission). Climate Change Minister Simon Watts said New Zealand was "on track" for its first two budgets (interest.co.nz).
Cost of the 2030 pledge. Treasury's June 2026 analysis estimates New Zealand would need 85 to 96 Mt of overseas mitigation to meet its first NDC, costing $4.4 to $5.0 billion in present value at a central price of about $53 a tonne, and $1.3 to $8.6 billion across its price range (Treasury). It put a further $0.2 to $1.6 billion on the 2035 pledge, and its 2023 range for the 2030 pledge had been $3 to $24 billion. There is no automatic penalty for missing a Paris target (ODT/RNZ).
Trade link. New Zealand's free trade agreement with the European Union includes an enforceable commitment to implement the Paris Agreement; a breach found by a disputes panel could lead to other trade obligations being lifted (BERL).
Farm emissions. The current government has ruled out a price on agricultural methane and relies on technology and industry partnerships (National). The Commission lists excluding agriculture from emissions pricing among policies that could increase emissions (interest.co.nz).
