Permanence Period

Permanence Period is one of the key concepts that defines the timeline of a ACCU scheme project.

This is the duration for which the sequestered carbon must be maintained. Project proponents can choose a permanence period of either 25 or 100 years. The permanence period begins when ACCUs are first issued to the project.

Crediting Period

This is the duration during which a project can generate ACCUs. For EP projects, the crediting period is 25 years.

Delivery Period

A delivery period is the duration of time of a carbon abatement contract under which ACCUs are delivered to the Clean Energy Regulator. It starts on the date a contract commences and continues until the contract expires. The maximum delivery period is seven or ten years depending on the project.

Reporting Period

Within the crediting period, project proponents must submit reports detailing the project's progress and carbon sequestration outcomes. For sequestration projects, reports must be submitted at least every 5 years.
