Corporate Emissions Reduction Transparency report

01 February 2024

The Corporate Emissions Reduction Transparency (CERT) report is a voluntary initiative for eligible companies to share with their customers, investors, employees and the community how they are progressing on their emissions and renewable electricity commitments. The information is presented in one place, using a standardised framework.

Participating in the next CERT report​

The CERT report is an opportunity for companies to show progress on reducing emissions or increasing their use of renewable electricity, using a standard framework. Participation is open to companies reporting over 50 kilotonnes of carbon dioxide equivalent (CO2​-e) emissions a year under the National Greenhouse and Energy Reporting​ (NGER) scheme.

The demand for climate related disclosures is increasing and the CERT report provides a space for companies to transparently report their net emissions position, including carbon unit surrenders​. The framework allows companies to use the data held by the Clean Energy Regulator to showcase their progress on climate-related commitments and to use data that has been independently verified by a third party for scope 3 (supply chain) emissions and international operations.

Feedback and sentiment from companies that participated in previous years included:

  • The CERT report allows for standardisation and comparison, where our sustainability report doesn’t. It is a space for us to share our emissions and progress towards targets with stakeholders and the market.
  • It has the flexibility to report on a wide range of sustainability targets, improves the integrity of disclosures and is good for our reputation.
  • We see the value in terms of increasing transparency.
  • The CERT report provides a link to the regulatory schemes and highlights where third-​party assurance has been obtained. The CERT report is useful for reporting to the board on targets and progress.
  • We like the idea of everything being reported publicly and in one spot.

How to participate

The opt-in period for the CERT report 2024 closed on 31 January 2024.​

Opt-ins for the 2025 CERT report will open in late 2024.

Introduction to CERT – November 2023

The CERT report tells the story of participants’ progress towards their climate related commitments alongside their peers. It uses a standardised framework that aligns with evolving international reporting frameworks. Eligible companies are encouraged to participate in this voluntary reporting process to build capability and capitalise on the opportunity to demonstrate their company’s climate action progress to their stakeholders, customers, investors and the public.

This webinar includes:

  • how to participate in the CERT
  • types of climate-related commitments
  • how progress is reported against commitments
  • reporting process and timeline.

Market-based accounting essentials – November 2023

Market-based accounting is an internationally recognised best-practice approach to electricity emissions accounting that empowers consumers to choose lower-emissions electricity sources. It is emerging as either a mandatory or an optional method in climate and emissions reporting and disclosure frameworks.

This webinar provides guidance on:

  • fundamentals of the electricity market and the Renewable Energy Target
  • difference between market-based and location-based accounting
  • tracking and claiming renewables
  • how emissions of various electricity sources are counted
  • treatment of on-site renewables (behind the meter consumption).
