About the Emissions Trading Register

Find out about the Register and view guides to help you navigate the Register and meet your legal requirements as part of the Emissions Trading Scheme.

We operate the New Zealand Emissions Trading Register (the Register), which is New Zealand’s national registry for emission units, including those owned by the Crown.

The Register acts like a bank, but it holds emission units instead of money. Businesses must have an account in the Register to be able to own or trade emission units in New Zealand. 

Anyone wanting to own or trade emissions units in New Zealand must have an account in the Register.
