Australia’s approach to climate and sustainability reporting is changing rapidly. With the introduction of AASB S2 Climate-related Disclosures by the Australian Accounting Standards Board, organisations required to prepare financial reports under the Corporations Act and meeting reporting thresholds will move from broad sustainability statements to structured, measurable and verifiable climate reporting aligned with global standards.
For many Australian reporting entities and the businesses within their supply chains, this is more than a compliance update. It is a shift that affects governance, strategy, risk management, procurement, tender eligibility, and financial transparency.
Understanding AASB S2 and preparing for it early will be essential for organisations that want to remain competitive, credible and compliant.
What is AASB S2?
AASB S2 is the Australian climate disclosure standard aligned with the International Sustainability Standards Board (ISSB) framework. It sets out how reporting entities must disclose climate-related financial information across five key areas:
- Governance of climate-related risks and opportunities
- Strategy and resilience of the business under climate scenarios
- Risk management processes
- Metrics and targets
- Disclosure of Scope 1 and Scope 2 greenhouse gas emissions, and Scope 3 greenhouse gas emissions where material, as part of climate-related metrics and targets
This standard treats climate risk as a financial and operational risk, bringing climate reporting into the same level of rigour as financial reporting.
Why AASB S2 Matters to Australian Businesses
Many organisations assume climate reporting applies only to large corporations. In reality, the impact of AASB S2 will flow through:
- Supply chains and procurement requirements
- Government and private sector tenders
- Investor and lender assessments
- Insurance and risk profiling
- Corporate governance responsibilities
Businesses within the supply chains of reporting entities that cannot clearly demonstrate their emissions profile, climate risks and sustainability strategy may find it increasingly difficult to win work, secure funding, or retain contracts.
Early preparation is now a strategic advantage.
Key Requirements Under AASB S2
Governance and Accountability
Reporting entities must disclose how climate-related risks are overseen at the Board and Executive level, with clear responsibility and reporting processes.
Climate Risk and Scenario Analysis
Reporting entities are required to disclose information about climate-related risks and opportunities and their impacts on operations, assets, supply chains and financial performance under future climate scenarios.
Emissions Disclosure and Carbon Accounting
Disclosure of Scope 1 and Scope 2 emissions, and Scope 3 emissions where material, is fundamental. This requires structured data collection across energy, fuel, waste, water and procurement activities using Carbon Accounting and Management practices.
Strategy and Resilience Planning
AASB S2 requires reporting entities to disclose how climate considerations are integrated into business strategy and long-term planning through a defined Sustainability Strategy.
Metrics, Targets and Performance Tracking
Organisations must disclose the metrics and targets they use to track sustainability and climate performance over time, not just commit to broad environmental goals.
Common Challenges Organisations Face
While many businesses recognise the importance of climate reporting, common barriers include:
- No clear baseline data for electricity, fuel, usage
- Confusion around Scope 3 emissions and supply chain data
- Difficulty linking sustainability efforts to governance and strategy
- Uncertainty about what regulators, investors and clients expect
- Lack of understanding of physical and transition hazards and risks
- Limited internal expertise in climate reporting frameworks
These challenges often prevent organisations from progressing from intention to action.
The Business Opportunity Behind Compliance
AASB S2 should not be viewed purely as a regulatory obligation. Organisations that take proactive steps can use climate reporting to:
- Strengthen tender submissions and procurement eligibility
- Improve operational efficiency and reduce resource costs
- Demonstrate leadership to customers, investors and stakeholders
- Build resilience against future regulatory changes and climate events
- Gain a competitive advantage within their industry
When approached correctly, climate reporting becomes a business improvement tool, not a compliance burden.
