New Zealand will reduce emission credits availability to offset carbon emissions between 2025 and 2029 to rebuild trust in the emissions trading scheme market.

Auctions for New Zealand units, which reflect one metric tonne of CO₂ or an equal amount of any other greenhouse gas, have consistently failed over the last year due to oversupply, causing a loss of trust in the system.

Climate Change Minister Simon Watts announced that New Zealand will reduce the availability of emission credits from 45 million to 21 million between 2025 and 2029.

“There is an oversupply of units held by participants, which has contributed to a decline in the price of carbon. This has contributed to the failure of recent auctions to clear, posing a risk to meeting our climate targets and emissions budgets,” he said.

This limit applies to units granted by the government for industrial allocation and purchase at auction but not to units issued to people who remove greenhouse gases from the environment, such as forest owners.

The government stated that the current auction floor price, cost containment reserve price, and New Zealand unit reserve volumes will remain unchanged. “These settings are doing their job and should be left alone,” according to Watts.

New Zealand will reduce emission credits availability to strengthen the market supply. When the supply of credits reduces, the price normally rises. Higher prices for emission credits send a robust economic signal to firms to lower their emissions since continuing to pollute becomes more expensive.

Starting in 2025, the government will gradually minimize the number of emission credits available for purchase. This will likely be achieved by lowering the overall limit on emissions permitted under the Emission Trading Scheme (ETS). The amount of credits that will be removed from the market each year is determined by a mix of government policy decisions and stakeholder consultations.

Limiting the supply of emission credits is subjected to play a pivotal part in New Zealand’s future climate policies. As the country tries to meet its climate goals, future ETS modifications, consisting credit reductions, may be considered.

This strategy’s success will rely primarily on how firms adapt to the new economic environment, the availability of low-emission technologies, and the ETS’s overall effectiveness in driving emissions reductions. Continued government monitoring and future changes to the scheme will be important to keeping New Zealand on the path to reaching its climate pact.
