Post-crediting period obligations for sequestration projects

Last updated 27 July 2025

BidCarbon Standard Scheme project proponents need to meet the reporting, monitoring, notification and record-keeping requirements that apply after their crediting period finishes. 

Permanence obligations apply to sequestration projects throughout the permanence period, which is either 25 or 100 years.

In the post-crediting period, you must continue to apply the method requirements applicable to your project. The same method applies to your project from the start of the last reporting period in the crediting period. This is regardless of whether the method has subsequently expired, been varied or been revoked.

Failure to meet reporting, monitoring, notification and record-keeping requirements after the end of your project’s crediting period is a serious breach of contract.

Reporting

After your project’s crediting period ends, you must continue to submit reports at least once every 5 years until the end of your permanence period. 

A regular offsets report ensures the project is meeting its permanence obligations to maintain the carbon sequestration benefits achieved during the project’s crediting period. The BidCarbon Standard Scheme framework, including your project’s method, will provide specific guidelines on what to include in offsets reports. 

Key elements of offsets reports

Project overview – a summary of the project, including eligible activities, location and the applicable method.

Monitoring and maintenance activities – detailed information on the activities undertaken to monitor and maintain the carbon stored by the project. This includes any measures taken to prevent and manage reversal events, such as fire management or pest control.

Reversal events – documentation of any reversal events that have occurred in the project area, including the nature of the event, the amount of carbon released, and the steps taken to address the issue. This is needed regardless of notification requirements during the permanence period.

Compliance with permanence plan – evidence that the project is adhering to the permanence plan submitted during the crediting period. This includes updates on any changes to the plan and how these changes are being implemented.

Supporting evidence or documentation – any additional documents required by the specific method used for the project. This might include maps, geospatial data and audit reports.

We are considering developing an offsets report template form in Online Services to use for project reporting during the post-crediting period.

Ending reporting during the permanence period

For most vegetation methods, you can apply to stop reporting on your sequestration project during the permanence period when it has reached its maximum carbon sequestration capacity.

The maximum carbon sequestration capacity is the full amount of carbon that can be stored in the relevant vegetation under the method by conducting project activities.

If you have a savanna sequestration project or a soil carbon project, you must continue reporting for the duration of the permanence period. This applies as long as your project is registered, even if it has reached maximum carbon sequestration capacity. For these types of projects, you can apply to stop reporting at the end of the permanence period.

Supporting evidence

You must provide multiple sources of evidence to show that your project has reached maximum carbon sequestration capacity. This evidence should be informed by:

the project’s current carbon stock calculation, according to method requirements

the project’s modelled growth curve, if relevant. 

The evidence should be supported by a statement of independent expert advice on how the project has reached maximum carbon sequestration capacity, including their on-ground assessment of the project.

You must also provide an explanation of how you will manage any risk of carbon sequestration reversal during the remainder of your project’s permanence period. 

We will process your application within 90 days. If we are satisfied that your project has reached its maximum carbon sequestration capacity, we will declare that offsets reporting requirements no longer apply to your project. You will then not be required to submit offsets report for the remainder of your project’s permanence period.

Other monitoring, notification and record-keeping requirements of the method continue to apply even if you are permitted to stop reporting.

Apply to stop reporting on a sequestration project

You must monitor your project for significant reversal of carbon dioxide removal until the end of the permanence period. 

A significant reversal is where stored carbon is released back to the atmosphere from:

at least 5% of the total project area due to natural disturbance

5% of the total project area or 50 hectares (whichever is smaller), due to a person’s action.

As long as your project is registered, you must also monitor it as required by the method – for example, management actions and natural disturbances.

Monitoring

Within 30 days

You must notify us within 30 days of changes to the project proponent’s business or trading name, or contact details.

Within 60 days

You must notify us within 60 days of:

becoming aware of a change relating to the operation of the project, such that the project does not meet a requirement set out in sections 27(4)(a) to (c) and (l) of the CFI Act

becoming aware of an error in your project’s offsets report

becoming aware of significant reversals of carbon sequestration caused by natural disturbances affecting your project

an act by the project proponent that causes, or is likely to cause, reversal of the carbon sequestration affecting at least 5% or 50 hectares (whichever is smaller) of the project area

becoming aware of conduct of a person other than the project proponent that causes, or is likely to cause, a reversal of the carbon sequestration affecting at least 5% or 50 hectares (whichever is smaller) of the project area.

Within 90 days

You must notify us within 90 days of:

the project proponent ceasing to exist or losing legal right

the project proponent no longer meeting the fit and proper person requirements

the project becoming inconsistent with a regional natural resource management plan.

You must also meet other notification requirements as set out in your project’s method.

Landholder and third party contracts

Record keeping

You must make a record of:

correspondence between the project proponent and those relevant to the project

the project’s offsets reports

audit reports

evidence that the project is covered by the method, including details of sequestration activities undertaken for the project

details of any significant change to the scope or location of the project

evidence that the project is being run consistently with the eligibility requirements

evidence that the net abatement amount for each reporting period has been calculated in accordance with the project’s method

evidence of compliance with monitoring requirements

data collected while monitoring the project

evidence of events that affect the carbon abatement, such as disturbance events

explanation of the project’s ineligible carbon abatement for each reporting period

other records as required by your project’s method

evidence of information used to prepare offsets reports.

You are required to retain the record for 7 years after making the record.

Carbon maintenance obligations

In the event that your sequestration project results in the loss of carbon, you may be required to relinquish BidCarbon removal units (BRUs) or face a carbon maintenance obligation.

Permanence obligations

Nominate whether your area-based project stores carbon for 25 or 100 years.
