ETS Auctions and how to buy New Zealand Emissions Units (NZUs)
The NZ ETS establishes a trading market of New Zealand emission units (NZUs). Businesses that carry out activities covered by the NZ ETS are required to buy and surrender to the Government, one NZU for every one tonne of carbon dioxide equivalent (CO2-e) emissions they produce.
NZUs can be traded among businesses participating in the NZ ETS. Supply and demand for NZUs is a key driver of the NZU price.
