“Reports don’t create credibility. Evidence does.”
There is a misconception that ESG reporting and sustainability reporting are fundamentally reporting exercises.
They are not.
Reporting is simply the visible outcome of thousands of individual decisions made throughout the year about what information is collected, how consistently it is measured, how accurately it is recorded and whether sufficient evidence exists to support every disclosure.
The report itself is the end product.
The real work lies in the quality of the data behind it.
This is why organisations that focus exclusively on producing better reports often overlook the single factor that determines whether those reports will withstand scrutiny.
Good data.
The relationship is remarkably simple.
Good data drives good reporting.
Bad data drives bad reporting.
Everything else follows from that principle.
Good Reporting Is the Outcome. Good Data Is the Cause.
Every sustainability report tells a story.
Investors, regulators, customers, employees and other stakeholders increasingly rely on that story when making decisions.
Yet the credibility of that story has very little to do with the quality of its writing or design.
It depends on whether every claim, performance indicator and material disclosure can be traced back to reliable, complete and well-supported information.
Frameworks continue to evolve.
Reporting standards continue to mature.
Stakeholder expectations continue to rise.
None of these developments changes the underlying reality that effective sustainability reporting begins with reliable data.
What Nearly One Million ESG Data Points Have Taught Us
At Integrated Reporting & Assurance Services (IRAS), our understanding of ESG data quality has been shaped by evidence rather than theory.
Each year, we review the sustainability reporting of every company listed on the Johannesburg Stock Exchange (JSE).
That process involves assessing performance against 264 sustainability indicators, generating more than 60 000 sustainability-related data points every year.
Since this research programme began, our proprietary database has grown to almost 900 000 ESG and sustainability data points.
That depth of analysis provides far more than statistical insight.
It reveals recurring reporting strengths.
It highlights common weaknesses.
Most importantly, it demonstrates where organisations continue to experience challenges in translating operational information into credible sustainability disclosures.
Our work extends well beyond JSE listed companies.
IRAS also performs Sustainability Data Completeness Assessments for organisations across multiple industries.
One ongoing engagement within the oil and gas sector involves evaluating more than 200 sustainability indicators across 16 companies, generating a further 3 200 data points annually.
This level of analysis is not undertaken because more data is inherently better.
It is undertaken because meaningful independent sustainability assurance depends upon evidence.
“Independent assurance is not about checking numbers. It is about testing whether the evidence supports the story being told.”
One of the most common misconceptions surrounding sustainability assurance is that it simply verifies whether reported information is mathematically correct.
In practice, assurance requires a much broader evaluation.
The objective is not merely to identify incorrect information.
It is to determine whether disclosures are complete, consistent both within and between companies, appropriately supported and presented with sufficient clarity for stakeholders to understand what they actually mean.
This often involves identifying information that appears inconsistent with disclosures in other reports, lacks supporting evidence or raises questions that the report itself does not answer.
The quality of assurance therefore depends upon far more than reviewing reported figures.
It depends upon understanding the evidence that produced those figures.
Why Bad Data Isn’t Always Wrong Data
One of the more interesting lessons from years of reviewing sustainability reports is that problematic data is not always incorrect data.
In many cases, reported information is technically accurate.
The difficulty lies elsewhere.
The supporting methodology may be unclear.
Important assumptions may not have been explained.
The context required to properly interpret the disclosure may be missing.
Alternatively, the evidence available may simply be insufficient to support the conclusion being presented.
From an assurance perspective, these distinctions matter.
Stakeholders are not only interested in whether information is accurate.
They also need confidence that it is complete, reliable and capable of supporting the broader narrative contained within the report.
This is precisely where independent sustainability assurance provides value.
Data Quality Is a Governance Issue
Strong ESG data supports far more than compliance.
It strengthens governance.
It improves internal decision-making.
It enables organisations to identify weaknesses before they become public issues.
It increases confidence among investors, regulators, customers and other stakeholders.
Perhaps most importantly, it enables organisations to move beyond simply reporting sustainability performance towards genuinely understanding it.
When organisations improve the quality of their data, they improve the quality of every decision that depends upon it.
Better reporting is simply one of the outcomes.
“Good reporting is not created when a report is written. It is created throughout the year, one reliable data point at a time.”
The conversation surrounding ESG reporting will continue to evolve.
Reporting frameworks will change.
Disclosure requirements will become more sophisticated.
Stakeholder expectations will continue to increase.
None of those developments changes the foundation upon which credible reporting is built.
Reliable data.
At IRAS, years of research, analysis and independent sustainability assurance have reinforced one principle above all others.
Good reporting does not create good data.
Good data creates good reporting.
Organisations seeking to improve the quality of their sustainability reporting should therefore begin in the same place every successful assurance engagement begins.
Not with the report.
With the evidence.
