AASB S2 Climate Reporting Support
Assurance provider &
capability advisor services
Is your business prepared for AASB S2 climate reporting?
At C6 ESG, we help Australian companies meet their new obligations under the AASB S2 Climate-related Financial Disclosures Standard. We are more than an assurance provider, we are your partner in building internal capability and confidence in climate reporting.
Why AASB S2 matters
The Australian Accounting Standards Board AASB has introduced AASB S2, aligned with the global IFRS S2 framework, to mandate climate-related disclosures in annual financial reports. These requirements are now being introduced progressively across Australian business sectors with both historic and forward projections, and directors are responsible for ensuring these disclosures are accurate, verifiable, and auditable.
Companies must move beyond sustainability marketing claims and begin treating climate disclosure as a core element of governance and financial risk management.
Our AASB S2 services
C6 ESG provides comprehensive AASB S2 support, tailored to match the level of assurance and maturity required by your organisation.
Pre-assurance gap assessments
Before your financial auditor begins formal assurance work, we can:
Conduct a climate reporting readiness assessment
Identify gaps in data, governance, risk frameworks, and disclosure content
Deliver a practical roadmap to strengthen your internal systems in advance
Assurance services: Limited and reasonable
We offer scalable assurance options that suit the current stage of your business:
Limited Assurance provides review based support for early stage disclosures
Reasonable Assurance delivers evidence backed verification of climate metrics, scenario analysis, and governance systems
Our independent assurance approach aligns with ASIC and investor expectations, enhancing trust in your disclosures
Capability building
We work alongside your team to establish robust internal systems, processes, and controls to:
Collect and manage verifiable emissions and climate risk data
Align your governance framework with ISSB, TCFD, and ASX Corporate Governance Principles
Build maturity over time so that your organisation can move confidently from limited to reasonable assurance

- Group 1 companies including large listed and asset intensive organisations preparing for 2025 and 2026 disclosure requirements
