The Corporate Emissions Reduction Transparency (CERT) report is a voluntary initiative for eligible companies to present a snapshot of progress on their emissions reduction and renewable electricity commitments.
This reader’s guide will help readers understand and interpret the range of commitment and reporting options used in the CERT report 2023. Definitions of key terms can be found in the
CERT report 2023 glossary.
Each participating company’s CERT report shows:
documentasset:data workbook contains additional information regarding each company’s commitments, including the calculations we use to assess the Clean Energy Regulator (CER) data verified commitments.
Based on feedback from participating companies, public consultation submissions and other stakeholders, the following updates were made for the CERT report 2023:
Companies that participate in the CERT report must adhere to the
documentasset: guidelines. These guidelines specify the information companies can provide for inclusion in their CERT report. However, there is some flexibility to allow companies to align their CERT report with their publicly disclosed commitments. In particular, the design of the CERT report aims to accommodate the complexity of joint venture arrangements and international corporate structures. The reporting choices made by companies affect how we calculate progress on their
CER data verified commitments, and how their net emissions position and renewable electricity percentage is presented.
Companies can choose an accounting approach in their CERT report for the:
Details of scope 2 accounting calculations can be found in the
documentasset: CERT report guidelines and
documentasset: supporting examples. Some calculation terms that are based on calendar year (for example, the Renewable Power Percentage) are adjusted as needed based on the company’s choice of reporting period.
When reporting on a calendar year or equity share basis, companies can choose to either:
More details, if applicable, are provided in the ‘Notes’ field of a company’s CERT report.
Each commitment card represents an emissions reduction or renewable electricity commitment. Companies can have multiple commitments, as well as commitments for their subsidiaries.
Broadly, there are three types of
commitments that can be included in a company’s CERT report:
Within each commitment card, the commitment and context statements are
provided by the company. The commitment statement summarises the commitment in the company’s own words. The context statement is an opportunity to provide additional, qualitative information relevant to the commitment to help readers understand the company’s operating environment. Additional details about the commitment are also presented, where provided by the company, including emissions coverage (scope 1, 2 or 3), whether the commitment applies to global efforts, and other frameworks the commitment is reported under.
CER data verified commitments are commitments where the CER has sufficient data to calculate and verify progress.
These commitment cards are labelled
CER data verified. The CER uses its data holdings, data-matching and other internal processes to calculate and verify a company’s progress on its commitments. The progress percentage value represents the percentage of the commitment goal achieved to date, along with an absolute progress figure (for example, in tonnes of carbon dioxide equivalent (CO2-e)).
Following each progress percentage value is a short description of the information used to calculate progress, such as:
Independently assured commitments have received limited or reasonable assurance from an independent and suitably qualified assurance provider (in accordance with relevant standards and accounting methods) for data provided by the company and used in the calculation of progress on the commitment. The underlying progress data is not verified by the CER. The CER calculates the progress percentage according to the CERT report calculation methodology outlined in the
documentasset:guidelines. The progress percentage value represents the percentage of the commitment goal achieved to date, along with an absolute progress figure (using the relevant metric).
Companies choosing this option may have commitments that cannot be verified using data held by the CER yet wish to recognise that their progress data has been independently assured by a third-party. Such commitments may include those related to scope 3 emissions, emissions intensity of products, and international emissions reductions. The progress data for these commitments must have received limited or reasonable assurance from an independent assurance provider in accordance with relevant standards and accounting methods.
For more information on the difference between assurance levels, visit
Levels of assurance explained.
Along with the level of assurance provided, other details about the assurance engagement are presented under the progress details, including:
Company assured commitments apply where progress cannot be calculated using data held by the CER and an independent assurance statement has not been provided. Such commitments may include those related to scope 3 emissions, the emissions intensity of products, and international emissions reductions.
The CERT report guidelines allow companies to choose how to frame these commitment statements. Companies are responsible for providing their own updates regarding progress on commitments. Updates can be qualitative or quantitative information and are not verified by the CER.
This section of a company’s CERT report shows its gross and net emissions, electricity use, renewable electricity percentage and Large-scale generation certificate (LGC) surrenders for the chosen reporting period for activities occurring in Australia. The values in the table are calculated by the CER, with the underlying data collected and verified by the CER or provided by the participating company with independent assurance.
The total net emissions are shown as a sum of scope 1 and scope 2 net emissions for the company.
Participating companies are required to report their scope 2 emissions under both location- and market-based accounting approaches. Dual reporting is in accordance with international best practice emissions accounting outlined in the
Greenhouse Gas Protocol Scope 2 guidance and the Australian Government’s
Climate Active initiative. For the
CERT report 2023, companies can choose whether to display their market-based data in their CERT report.
The emissions data for companies reporting on a calendar year or equity share basis may vary from their NGER-reported data. In this case, the quantities are based on either multiplier-adjusted NGER data and presented as
CER data verified, or on separately provided independently assured data with assurance details included.
Companies that report equity share data using the multiplier method must supply equity share percentages for each NGER facility they have an ownership share of, such as a joint venture (including those outside of their operational control). Emissions and electricity values are adjusted accordingly.
Companies that report calendar year data using the multiplier method must supply multipliers to reflect how their data has varied from their NGER-reported financial year data to the most recent calendar year. Their historic calendar year data is estimated as the average of the two overlapping NGER reporting years.
Companies reporting equity share or calendar year data using the independent assurance method must provide an assurance statement from an independent and suitably qualified assurance practitioner for all metrics used in the calculation of net emissions and renewable electricity use. We calculate net emissions and renewable electricity use based on the independently assured quantities according to the CERT report calculation methodology described in the
documentasset: CERT report guidelines. Details of the assurance engagement are shown in the notes section below the net emissions and renewable electricity data.
The notes provide additional information to assist readers in interpreting the net emissions and renewable electricity data. Notes in this section also outline how company data presented in the CERT report may differ from company data published elsewhere. For example, where a company has chosen calendar year reporting for their CERT report, a note is provided in this section to inform readers that the company’s CERT report may not align with their NGER-published data, as the NGER scheme operates on a financial year basis.
Some company CERT reports show the proportion and number of units cancelled, retired, or surrendered by the company for the reporting year. Units may not necessarily be surrendered against specific commitments. Units may have been surrendered by a third party on behalf of the company (for example,
Australian carbon credit units (ACCUs) procured from third party carbon offset providers). Where no units have been surrendered by the company in relation to their CERT report ‘no units surrendered’ will be displayed.
Units surrendered by companies in relation to scope 3 emissions are not included in the chart but may be noted in the commitment or company context statements.
The supporting information section in a company’s CERT report shows the broader context relevant to the participating company’s net emissions position, emissions reduction or sustainability efforts that may not relate directly to their commitments. This information is provided by the company.
The resources section in a company’s CERT report provides links to the CERT report data workbook, CERT report guidelines, the CERT report 2023 glossary and the highlights of the latest NGER report.
