Australian Sustainability Reporting Standards (ASRS): What It Means for Australian Organisations
Australia has formally introduced a mandatory climate-related financial disclosure regime through the Australian Sustainability Reporting Standards (ASRS), embedding sustainability into statutory financial reporting.
The 2024 reforms to the Corporations Act 2001 establish a consistent, enforceable framework for climate disclosures. This marks a structural shift from voluntary ESG reporting to mandatory, financially material disclosures integrated into governance, risk, and financial decision-making.
Group 1 entities will begin reporting for financial years starting on or after 1 January 2025, with the first Sustainability Reports lodged with the Australian Securities and Investments Commission (ASIC) in 2026.
The regime applies to listed entities, large private companies, financial institutions, and emissions-intensive organisations, fundamentally redefining how climate risk is assessed, governed, and disclosed.
The situation remains fluid, and reported figures and impacts are subject to change as events evolve.
It is in that spirit — not of opportunism, but of responsibility — that we address what this crisis is also exposing: structural vulnerabilities in the global energy system that have long been understood but insufficiently addressed. The scale and speed of disruption now visible in oil, gas, and shipping markets are forcing governments and businesses alike to confront a difficult reality: energy systems designed for efficiency are often fragile under stress.
From Voluntary to Mandatory: The Shift to ASRS
Pre-ASRS Landscape
Prior to ASRS, climate and sustainability reporting in Australia was largely voluntary, driven by investor expectations, stakeholder pressure, and internal ESG commitments. While several frameworks were widely adopted, there was no uniform legal standard governing disclosure quality, comparability, or assurance.
Commonly used frameworks included:
- Task Force on Climate-related Financial Disclosures (TCFD)
- Global Reporting Initiative (GRI) Standards
- CDP (formerly Carbon Disclosure Project)
Large emitters reported under the National Greenhouse and Energy Reporting (NGER) scheme, which provided emissions and energy data but did not address financial materiality, governance integration, or forward-looking risk assessment.
This fragmented landscape limited comparability and decision-usefulness, creating the need for a standardised regulatory framework.
ASRS Framework in Practice
The ASRS framework, issued by the Australian Accounting Standards Board (AASB), introduces two core standards:
- AASB S1: General Requirements for Disclosure of Sustainability-related Financial Information
- AASB S2: Climate-related Disclosures (aligned with IFRS S2)
AASB S2 forms the foundation of climate disclosure and is structured around four pillars:
- Governance
- Strategy
- Risk Management
- Metrics and Targets
Organisations are required to disclose Scope 1 and Scope 2 emissions from year one, with Scope 3 subject to transitional relief and safe harbour provisions.
Sustainability Reports must be included within annual financial reporting and lodged with ASIC, reinforcing the direct linkage between climate risk and financial performance.
Who Must Report and When
The rollout is phased based on organisational size, with entities required to meet at least two of the following thresholds:
Group | Revenue | Assets | Employees | Reporting Start |
Group 1 (Largest) | > $1 billion | > $500 million | > 500 | 1 Jan 2025 |
Group 2 | > $500 million | > $250 million | > 250 | 1 Jul 2026 |
Group 3 | > $50 million or listed | > $25 million | > 100 | 1 Jul 2027 |
Organisations should assess both thresholds and timing in line with AASB guidance to determine applicability.
The Next Phase of Disclosure
ASRS represents the foundation of a broader reporting evolution. Over time, disclosure requirements are expected to expand and deepen, including:
- Progression from limited to reasonable assurance
- Nature-related and biodiversity disclosures
- Expanded environmental and social reporting requirements
This trajectory reinforces the need to build scalable systems and governance structures early, rather than treating ASRS as a one-off compliance exercise.
Preparing for ASRS Compliance
With Group 1 reporting commencing, organisations should prioritise structured and early preparation. Key focus areas include:
- Confirming reporting scope and applicable timelines
- Undertaking AASB S2 gap assessments
- Establishing robust emissions measurement systems (Scope 1, 2 and 3)
- Strengthening governance and accountability frameworks
- Conducting climate scenario analysis and financial impact assessment
- Preparing for assurance and director-level disclosures
A proactive approach reduces compliance risk and ensures disclosures are defensible, audit-ready, and decision-useful.
Why ASRS Matters
ASRS is not just a reporting requirement—it embeds climate risk into core business operations. It introduces:
- Legal accountability and regulatory oversight
- Increased investor and stakeholder scrutiny
- Integration with financial planning and capital allocation
- Strengthened board-level governance and oversight
Sustainability reporting is transitioning from a communications exercise to a financially material, audit-ready discipline that informs strategic decision-making.
Advisory and Implementation Considerations
Organisations are approaching ASRS readiness from different starting points, depending on the maturity of their governance frameworks, data systems, and existing disclosure practices.
In practice, preparing for ASRS requires a combination of regulatory interpretation, gap assessment, and the design of processes that support consistent, verifiable, and audit-ready disclosures. This often includes strengthening governance structures, establishing emissions data management systems, and aligning climate-related risks with financial planning and reporting.
Experience across the Australian market indicates that organisations benefit from integrating advisory, data, and reporting capabilities early, enabling a more structured and efficient transition from voluntary disclosures to mandatory reporting.
Climate Change Response (CCR) has supported organisations across Australia and globally in sustainability reporting, climate disclosure, and regulatory compliance. This includes designing bespoke reporting platforms, working across sectors to interpret evolving requirements, support implementation of reporting frameworks, and build internal capability aligned with ASRS and broader global standards.
What this means for Organisations
ASRS establishes a mandatory, standardised, and enforceable framework for climate-related financial disclosure in Australia.
Organisations that act early by embedding governance, strengthening data systems, and aligning strategy with climate risk will not only achieve compliance but also position themselves to respond effectively to future regulatory and market expectations.
