Stop pretending the farm exemption made New Zealand’s carbon bill disappear

The bill did not vanish, it changed address

Removing agriculture from the Emissions Trading Scheme was sold as relief for farmers. Documents proactively released on 21 August 2026 confirm what the official advice always said: the emissions obligation did not disappear, it was transferred. The ETS now covers only about 40 percent of New Zealand’s greenhouse gases, and officials are blunt that it “is not expected to meet” the emissions budgets on its own.

The same advice states that recent decisions on the 2050 methane target and the removal of agricultural pricing have “increased reliance on other sectors” and “increased the size of the gap”. Translation for business owners: the sectors still inside the scheme, transport, energy and heavy industry, now shoulder a share of reductions that agriculture would otherwise have carried.

How big the hole actually is

The January 2026 amendment addendum to the second emissions reduction plan is the current official projection, and the numbers are stark. New Zealand is off track for the third emissions budget (2031-35) by 8.7 million tonnes of CO2 equivalent under the central scenario. Removing agricultural pricing alone wiped out an estimated 10.6 million tonnes of projected reductions in that budget period, while agricultural emissions are forecast to rise by 4.8 million tonnes across 2026-30 on the back of higher stock numbers.

A June 2025 official briefing modelled what closing that gap through ETS sectors alone would cost. Under one scenario, carbon prices would need to run at least $30 higher through the 2030s, peaking around $105 per tonne in 2035. These are modelled scenarios, not forecasts, but the direction is not in dispute. The same briefing noted every $10 increase in the carbon price adds about $90 a year to average household spending. For fuel-intensive and energy-intensive operations, the exposure is proportionally larger.

Ministers were not blindsided

This is not officials springing bad news on unsuspecting politicians. Unredacted Cabinet papers published by Newsroom in April 2026 show Climate Change Minister Simon Watts told colleagues directly that “the less abatement achieved in agriculture, the more will be needed from NZ ETS sectors.” That April 2026 investigation found higher carbon prices to compensate for rising farm emissions could add $270 a year to the average household budget, with officials warning prices “may need to be considerably higher.”

The warnings ran back further. In 2024, Ministry for the Environment and Treasury officials concluded there was “limited evidence” the approach would work, cautioning that “other sectors of the New Zealand economy will be bearing the share of emissions reductions that should be borne by the agricultural sector.” A March 2024 regulatory impact statement had modelled processor-level ETS entry with a positive benefit-cost ratio of 1.24 and a net present value of $0.97 billion over 20 years. That option was abandoned.

Who pays, in practice

Transport is the most exposed. It accounts for 17.5 percent of gross emissions, 90 percent of that from road, so every carbon price rise flows into diesel, freight and logistics costs. Heavy industry sits alongside it. Fonterra, Z Energy, BP and Mobil remain inside the scheme and face rising surrender obligations. The November 2024 legislation that removed agriculture also cut its reporting: the EPA’s 2025 emissions report showed reported ETS emissions halved from 65.7 to 32.5 million tonnes almost entirely because farm reporting stopped.

There is a trade risk too. In 2024, the Environmental Defence Society warned that the exemption without an alternative plan “poses a high risk to New Zealand’s FTAs” and to exporters facing carbon border adjustment mechanisms in key markets.

The bet, and the timing

The government is not ignoring farm emissions. It is investing over $400 million over four years in mitigation technology through AgriZero NZ and the Ag Emissions Centre, betting technology, not pricing, delivers cuts. But even with projected abatement, farm emissions still rise on net. The gap between what technology might deliver and what the budgets require is exactly where pressure on other sectors comes from.

And the fix has been parked. A Cabinet committee has directed officials to develop options and report back after the 2026 general election. Businesses in transport, energy and manufacturing should price the trajectory into contracts and fleet decisions now. The carbon bill did not shrink. It just landed on a different desk, and that desk is yours.
