Why Many Sustainability Reports Are Not Ready for Assurance

As sustainability reporting continues to evolve, many organisations are discovering an important reality:
Producing a sustainability report and being ready for external assurance are not the same thing.
A report may appear comprehensive, professionally designed, and aligned with recognised frameworks such as the Global Reporting Initiative GRI Standards, yet still contain weaknesses that create significant challenges during assurance.
In many organisations:
- evidence trails are inconsistent
- data ownership is unclear
- methodologies are insufficiently documented
- responsibilities are fragmented
- value-chain visibility is limited
- governance oversight remains weak
These issues may not always be visible externally, but they often emerge during assurance reviews.
Importantly, assurance readiness is not only about compliance.
It is also about improving:
- reporting quality
- transparency
- stakeholder confidence
- governance
- internal decision-making
- long-term resilience
An effective Assurance Readiness Review may examine:
- governance and accountability structures
- evidence availability and traceability
- reporting methodologies
- data collection processes
- stakeholder engagement
- double materiality processes
- value-chain visibility
- consistency of disclosures
- alignment with reporting frameworks
- internal review and approval procedures
Organisations that strengthen these areas early are often better positioned to:
- improve reporting quality
- reduce future reporting risks
- prepare for evolving assurance expectations
- support better sustainability-related decisions
- enhance stakeholder trust
To help organisations better understand their current position, FBRH Consultants has developed a free Assurance Readiness Self-Assessment.
The assessment takes approximately 3–5 minutes to complete and is designed to help organisations identify potential strengths, weaknesses, and areas for improvement in their sustainability reporting and assurance preparedness.
