Mandatory Climate Disclosures and the Australian Sustainability Reporting Standards

The Australian Government’s introduction of mandatory climate-related financial disclosures legislation under the Australian Sustainability Reporting Standards (ASRS), mean transparency and accountability in climate-related reporting are now mandatory for a large cohort of Australian businesses.

Is your organisation prepared to navigate the complexities of the new Australian Sustainability Reporting Standards (ASRS) AASB S2 and comply with mandatory climate-related disclosures?

What are the Australian Sustainability Reporting Standards (ASRS)

The new Australian Sustainability Reporting Standards (ASRS), are aligned internationally with the ISSB Standards, and will redefine corporate responsibility in Australia. The standards are sometimes referred to as Mandatory Climate Disclosures (MCD) or Mandatory Climate Reporting (MCR).

The standard AASB S2 mandates comprehensive reporting on climate-related financial information, including climate risks, opportunities, and GHG emissions. By enhancing transparency and accountability, they will ensure that sustainability is integral to corporate strategy and operations, supporting Australia’s emission reduction targets​.

Note ASSB S1 sustainability standard is currently voluntary, but future-focused organisations are already looking at this to prepare for potential compliance in the years ahead.

Who needs to comply with ASRS?

The mandatory climate disclosures to ASRS impacts a wide range of entities, including:

• Large Corporations: Large entities exceeding 2 out of 3 thresholds for 1) consolidated revenue, 2) EOFY consolidated gross assets and 3) EOFY employees.
• NGERs Act Reporters: Companies already reporting under the National Greenhouse and Energy Reporting (NGER) Act.
• Asset Owners and Managers: Managing assets in investment schemes and superannuation funds over $5 billion.

It is essential to determine early on whether your business falls under these categories to ensure timely compliance with the new standards.

Understanding the ASRS Framework

The ASRS framework is designed to integrate seamlessly with existing global standards, enhancing the comparability of disclosures worldwide. It encompasses:

• Governance: How organisations govern and assess climate-related risks and opportunities.
• Strategy: The actual and potential impacts of climate-related risks and opportunities on business, strategy, and financial planning.
• Risk Management: The processes used to identify, assess, and manage climate-related risks.
• Metrics and Targets: Metrics and targets used to assess and manage relevant climate-related risks and opportunities.

How to Prepare for Mandatory Climate Disclosures to AASB S2 under the ASRS

1. Risk and Governance Assessment: Ensure your governance framework robustly manages climate risk. Begin by assessing your current risk profile and governance to align with ASRS requirements.
2. Skills and Capabilities Review: Evaluate your internal capabilities to meet these disclosures. Where necessary, seek to bridge knowledge gaps through training or hiring, ensuring your team is up to speed with the latest in climate risk management.
3. Action Plan Development: Develop a comprehensive action plan to address any compliance gaps. Set clear milestones and deadlines to achieve ASRS readiness before 2025.
