Sustainability performance

It's our responsibility to be open and transparent about what we do. Ongoing disclosures about our sustainability performance are part of this.

Integrating sustainability into everything we do

AGL recognises that transparent reporting about our strategy, our performance and our challenges is an essential part of our responsibility to our shareholders and other stakeholders, and to maintaining our licence to operate.

Our Annual Report and ESG Data Centre provide comprehensive sustainability performance data across seven key dimensions: Customers, Assets, People, Relationships, Environment, Business Intelligence and Finance.

Reporting frameworks

International Integrated Reporting Framework

AGL’s FY23 Annual Report has been prepared with reference to the International Integrated Reporting Council’s (IIRC) International Integrated Reporting Framework, as we believe it provides a useful basis for disclosing how we create sustainable value for our shareholders and other stakeholders over time. We have used this framework since FY19 to demonstrate how consideration of risks and opportunities (both those arising from our business and those that exist in a broader operational context), our purpose and our values drive our strategy. We have also considered how the execution of our strategy creates value, applying a lens that is broader than financial performance alone.

Sustainability Accounting Standards Board (SASB)

AGL has aligned the disclosures made in the FY23 Annual Report to the Sustainability Accounting Standards Board (SASB) standards for Electrical Utilities and Power Generators and Gas Utilities.

SASB index is included in the FY23 ESG Data Centre which identifies the extent to which each SASB disclosure requirement has been applied.

Taskforce on Climate-Related Financial Disclosures

We are committed to reporting in line with the Task Force on Climate-related Financial Disclosures (TCFD) framework.

We engaged Deloitte to undertake limited assurance over selected non-financial key performance indicators (KPIs) included within the Business Value Driver scorecards in our FY22 Annual Report, in accordance with the Australian Standard on assurance engagements ASAE 3000 Assurance Engagements other than Audits or Reviews of Historical Financial Information issued by the Australian Auditing and Assurance Standards Board. Full details of the assurance process and outcome are included in the assurance statement included in the FY23 Annual Report.

Historical Sustainability Performance

As a result of the adoption of Integrated Reporting principles in FY19, AGL is no longer publishing a separate, stand-alone Sustainability Report. However, operating our business sustainably and ensuring we continue to provide transparent disclosures about our sustainability performance for our stakeholders is still central to who we are.

Information about AGL’s historical sustainability performance is available in our past Sustainability Reports (until FY18) and Annual Reports (from FY19):
