About the Emissions Trading Register

Find out how the Register works 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, which is New Zealand’s national registry for emission units. Anyone wanting to own or trade emissions units in New Zealand must have an account in the Register.

The Register acts like a bank, but it holds emission units instead of money. It holds all the emission units in New Zealand, including those owned by the Crown.

Emission unit trading

Emissions units are a type of currency that are traded through the New Zealand Emissions Trading Register.
