What is the difference between ACCUs and SMCs?

ACCUs are issued to registered projects that store carbon or avoid emissions, while SMCs are issued to Safeguard facilities that emit below their baselines. Both can be surrendered to reduce a Safeguard facility's net emissions, but only ACCUs are offsets and only ACCUs can be voluntarily cancelled.

What is an ACCU carbon abatement contract?

A carbon abatement contract is an agreement to sell ACCUs to the Australian Government, represented by the Clean Energy Regulator, at a set price.
