Under the Carbon Credits (Carbon Farming Initiative) Act 2011 we publish information about the number of Australian carbon credit units (ACCUs):

  • issued by us
  • relinquished
  • cancelled.

Publishing information about the supply of ACCUs can facilitate the establishment of carbon markets, including for price discovery.

For the most up to date data, go to the ACCU Scheme project and contract register.
