Corporate Emissions Reduction Transparency (CERT) report

The CERT report is a voluntary initiative that supports climate-related disclosures by eligible National Greenhouse and Energy Reporting (NGER) reporters. It publishes participant's climate-related commitments, progress, and net emissions position.

NGER reporters that want to publish information about their use of offsets and renewable electricity (including Greenpower and renewable energy certificates), can find out how to participate in the next CERT report.

Prior to the introduction of the CERT report, we published annual NGER reports with data from registered corporations and reporting transfer certificate holders that met the publication threshold. The reports included:

GreenPower purchased
number of renewable energy certificates surrendered
offset scope 2 emissions.

We published this data to recognise the impact voluntary renewable energy purchases by registered corporations had in reducing their scope 2 greenhouse gas emissions. A corporation's offset scope 2 emissions total only considered renewable energy certificates that were voluntarily surrendered.

Scheme reporters provided the information voluntarily. It was not required under the National Greenhouse and Energy Reporting Act 2007. The data published under the NGER scheme for GreenPower represents a portion of voluntary surrender across the market. It does not capture transactions reported under the Renewable Energy Target.

Notes about this publication

Offset scope 2 emissions totals are calculated by a corporation deducting electricity that it has purchased using either GreenPower and/or renewable energy certificates, from its total electricity consumption. This net electricity consumption figure is then used to calculate an offset total for the corporation's total scope 2 greenhouse gas emissions.
