NZ ETS unit settings and annual regulatory updates 2025
Overview
Consultation was held on the Government’s annual review of auction settings and other regulations for the New Zealand Emissions Trading Scheme (NZ ETS).
The NZ ETS supports Aotearoa New Zealand to meet its emissions reduction goals by putting a price on greenhouse gas emissions. Businesses must provide a New Zealand Unit (NZU) to the government for every tonne of climate pollution they emit.
Participants in the NZ ETS can purchase NZUs through government auctions held four times per year. Auction settings are reviewed every year to ensure the NZ ETS is working well to support climate targets.
Price control settings set a minimum and maximum price for NZUs at auction.
Unit limit settings help “cap” the supply of units into the NZ ETS over time. This helps to keep emissions in line with greenhouse gas reduction targets.
