Emission units transferred
Each month we release data on the number and type of units traded between accounts in the New Zealand Emissions Trading Register.
This graph shows monthly data over 12 months for the number of units traded between accounts in the Register, including overseas transfers. Transactions involving the Crown (including surrenders) are not included.
We update this graph on the second working day of each month.

There have been no international transactions since 19 November 2015, and therefore the volume of total transactions will be equal to the domestic transactions.
This information is also available to download, including all historical data going back to 2008.
You can find more information on the types of units that can be traded in the ETS on our Surrendering units page.
