Common ESG Reporting Mistakes Australian Businesses Make (and How to Avoid Them)
As Australian organisations prepare for mandatory AASB S1 and S2 reporting, many encounter common pitfalls that reduce disclosure quality and create compliance risk. Learning from these mistakes can help your organisation avoid costly remediation. This guide identifies frequent ESG reporting errors and how to prevent them.

Governance and Process Mistakes
Mistake 1: Treating ESG as Finance Team Responsibility Only
Problem: Finance teams focus on financial risks, missing operational and social ESG issues requiring input from HR, operations, and business leaders.
Solution: Establish cross-functional ESG steering committee. Assign responsibility to specific departments for their material ESG topics. Finance coordinates but doesn’t own all disclosure.
Mistake 2: Starting Reporting Without Board Approval
Problem: ESG disclosures made without board oversight; disclosures contain misstatements or don’t reflect board-approved strategy.
Solution: Board reviews and approves materiality assessment, ESG strategy, key targets, and final disclosures before publication.
Mistake 3: Weak Data Governance
Problem: No clear ownership of data collection; metrics calculated differently by different departments; no audit trail of data changes.
Solution: Assign data ownership to specific roles. Document calculation methodologies. Implement data validation and approval workflows. Maintain audit trail of all data submissions and changes.
Data Quality Mistakes
Mistake 4: Mixing Actual and Estimated Data Without Disclosure
Problem: Some metrics are calculated from actual measurements, others from estimates or assumptions, but this distinction isn’t disclosed. External auditors identify inconsistency.
Solution: Clearly indicate which metrics are actual vs estimated. Explain estimation methodologies. Quantify uncertainty ranges where applicable (e.g., “±15% due to estimation”).
Mistake 5: Scope Creep or Scope Changes Without Explanation
Problem: Year 1 report includes 10 facilities. Year 2 report includes 15 facilities. Readers can’t tell if improvement is real or due to including more operations.
Solution: Clearly define scope boundary (entities, facilities, geographies) in each report. If scope changes, explain the change and either restate prior-year comparatives using new scope, or separately disclose comparables on consistent basis.
Mistake 6: Ignoring Materiality in Data Collection
Problem: Collecting and disclosing all possible ESG metrics regardless of materiality, leading to cluttered reports that obscure what’s actually important.
Solution: Focus data collection on material topics only. Use materiality assessment to prioritise ESG metrics. This improves focus and reduces reporting burden.
Disclosure Content Mistakes
Mistake 7: Weak Governance Disclosure
Problem: Board and management structures for ESG not clearly explained. Readers can’t understand who’s responsible for ESG decisions.
Solution: Explicitly describe board committees responsible for ESG, management roles, reporting lines, and how ESG flows to board discussions. Reference policy documents that detail governance processes.
Mistake 8: Strategy Disclosure Without Connection to Business Model
Problem: ESG strategy presented in isolation from business strategy, making it appear disconnected from core business.
Solution: Explicitly explain how ESG factors affect competitive positioning, market access, capital allocation, and financial performance. Use integrated reporting approach to show connectivity.
Mistake 9: Targets Without Credible Pathways
Problem: Organisation commits to net-zero by 2050 but provides no interim targets, identifies no transition actions, and explains no business model changes needed to achieve target. Appears greenwashing.
Solution: Set interim targets (e.g., 50% reduction by 2030). Explain specific actions and investments planned. Disclose assumptions and risks to achieving target. Demonstrate target credibility through scenario analysis.
Mistake 10: Vague or Unsupported Claims
Problem: Claims like “we are a sustainability leader” without substantiation; claims about “net zero” without defining scope or methodology.
Solution: Substantiate claims with data and evidence. Define terms clearly (e.g., net zero includes Scope 1, 2, and Scope 3). Disclose calculation methodologies. Avoid marketing language without support.
Assurance and Compliance Mistakes
Mistake 11: Inadequate Preparation for External Assurance
Problem: Assurance provider begins work to find inadequate documentation, data quality issues, or calculation errors. Results in qualification of assurance opinion or delays in report publication.
Solution: Engage assurance provider early (6 months before reporting deadline). Provide complete data documentation. Conduct internal audit of data quality before external assurance. Allow time for remediation of identified issues.
Mistake 12: Not Addressing Prior-Year Assurance Qualifications
Problem: Year 1 assurance report identifies data quality gaps or missing methodologies. Year 2 report repeats the same issues.
Solution: Treat assurance qualifications seriously. Develop remediation plan. Monitor progress. Demonstrate to assurance provider that you’re addressing issues. This improves Year 2 assurance opinion and credibility.
Communication Mistakes
Mistake 13: Selective or Misleading Presentation of Data
Problem: Report highlights achievements (e.g., 10% emission reduction) while downplaying challenges (e.g., overall emissions still 20% above target) or omitting unfavourable metrics.
Solution: Present balanced view of performance. Disclose both achievements and challenges. Explain unmet targets. Candid disclosure builds stakeholder trust.
Mistake 14: Insufficient Context for Metrics
Problem: Report discloses “500,000 tCO₂e emissions” without explaining what this represents or how it trends year-on-year.
Solution: Provide context: prior-year comparatives, intensity metrics (emissions per unit of revenue), targets and progress toward targets, industry benchmarks.
Avoiding These Mistakes: Best Practices
- Start early—begin preparation 12+ months before reporting deadline
- Establish governance—assign clear ownership and oversight
- Conduct materiality assessment—focus on what matters
- Implement data systems—automate where possible, establish controls
- Document everything—calculation methodologies, assumptions, decisions
- Engage external advisors—assurance provider, sustainability consultant
- Review and refine—internal review, external assurance, board sign-off before publication
- Communicate clearly—explain, contextualise, substantiate claims
- Monitor and improve—track issues, update processes, demonstrate continuous improvement
Frequently Asked Questions
What if we’ve already made some of these mistakes in Year 1 reporting?
Proactively address in Year 2 reporting. Explain what has been improved and why. Demonstrate commitment to continuous improvement. This shows responsiveness to feedback and builds credibility.
How can we avoid greenwashing accusations?
Substantiate all claims with evidence. Disclose limitations and assumptions. Present balanced view of performance and challenges. Obtain external assurance. Over-disclose rather than under-disclose on limitations.
Moving Forward with Quality ESG Reporting
Avoiding common ESG reporting mistakes requires planning, governance, rigorous data management, and transparent communication. Organisations that invest in these areas from the outset produce credible, compliant reports that enhance investor confidence and stakeholder trust.
