Three ESG Reporting Gaps That Undermine Trust—and How to Fix Them

When a company publishes an ESG report, it signals transparency and accountability. But too often, those reports contain gaps that erode the very trust they aim to build. Readers—investors, regulators, employees—have grown skeptical of glossy sustainability pages that cherry-pick data or promise vague improvements. In this guide, we focus on three specific reporting gaps that undermine trust and, more importantly, how to fix them. We'll draw on patterns observed across industries, not hypotheticals, and offer concrete steps you can implement today.

Where Trust Breaks Down: The Three Gaps in Practice

Trust breaks down when stakeholders sense a mismatch between what a company says and what it does. In ESG reporting, this happens in three predictable places: selective metric disclosure, unambitious targets, and superficial assurance. Each gap has a distinct mechanism and a fix that goes beyond checklist compliance.

Selective Metric Disclosure

Companies often report metrics that show them in a favorable light while omitting those that reveal risk. For example, a manufacturer might highlight reductions in water intensity per unit but omit absolute water withdrawal figures, which may be increasing due to production growth. This selectivity is not always deliberate—teams may lack data or feel overwhelmed by the number of potential indicators. But the effect is the same: stakeholders sense something is missing.

Vague or Unambitious Targets

Targets like “reduce emissions by 20% by 2030” sound good until you realize the baseline year was chosen to make the reduction look larger, or the target excludes Scope 3 emissions. Without context on baseline selection, scope boundaries, and alignment with climate science, targets become marketing claims rather than commitments.

Superficial Assurance

Third-party assurance can add credibility, but only when it covers material metrics and follows a recognized standard. Some companies obtain “limited assurance” on a tiny subset of data, then imply their entire report is verified. This practice, sometimes called audit-washing, misleads readers and invites regulatory scrutiny.

These gaps are not isolated; they compound. A report with selective metrics and vague targets, even if assured, will still fail to build trust. The fixes must address all three together.

Why the Gaps Persist: Common Misunderstandings

Many teams believe they are reporting correctly. The gaps often stem from confusion about what ESG reporting is supposed to achieve. Three foundational misunderstandings are particularly common.

Confusing Activity with Outcome

Teams report on ESG activities—number of audits conducted, training hours completed—as if they were outcomes. But stakeholders care about results: did emissions go down? Did safety incidents decrease? Activity metrics can mask poor performance. For instance, a company might boast about conducting 50 supplier audits, but if those audits never lead to corrective actions, the number is meaningless.

Equating All Standards with Credibility

Not all reporting frameworks are equal. Using a framework like GRI or SASB is a good start, but it does not guarantee the report is trustworthy. The framework is a structure, not a seal of approval. Credibility comes from how the framework is applied—whether the company reports on all material topics, not just the easy ones, and whether it explains omissions.

Believing Assurance Solves Everything

Some companies treat third-party assurance as a silver bullet. They assume that once an auditor signs off, the report is beyond reproach. But assurance scope matters. If the auditor only checks a few data points, or if the assurance standard is weak, the report can still be misleading. Assurance should be seen as a tool, not a shield.

Correcting these misunderstandings is the first step toward closing the gaps. Teams need to shift from a compliance mindset to a communication mindset: the goal is not to check boxes but to tell a honest, complete story.

Patterns That Work: Building Trustworthy Reports

Over time, a set of practices has emerged that consistently produces more credible ESG reports. These patterns are not revolutionary, but they require discipline to implement.

Start with Materiality

A materiality assessment—identifying the ESG issues that most affect financial performance and stakeholder decisions—should drive what gets reported. This ensures the report focuses on what matters, not what is easy. Leading companies update their materiality assessment every two to three years and disclose the process, including how stakeholders were consulted.

Set Science-Aligned Targets

For climate and environmental metrics, targets should be aligned with external benchmarks like the Science Based Targets initiative (SBTi) or sector-specific decarbonization pathways. This provides context: stakeholders can see whether the company’s ambition matches the scale of the challenge. Even for social metrics, benchmarks like living wage calculations or industry injury rates can anchor targets in reality.

Use Assurance Strategically

Rather than seeking minimal assurance on a few metrics, companies should identify the most material data points and obtain reasonable assurance on those. This signals that the company is confident in its numbers. It also forces internal data quality improvements, which benefit decision-making beyond reporting.

These patterns work because they address the root causes of distrust: they make reporting material, contextual, and verified. But they require upfront investment in data systems and governance.

Anti-Patterns: Why Teams Revert to Bad Habits

Even when teams know the right approach, pressure to produce quick results can pull them back into old habits. Recognizing these anti-patterns is essential to avoiding them.

Metric Creep

Over time, companies add more and more metrics to their reports, trying to cover every possible stakeholder request. The result is a bloated report that obscures what is material. Teams revert to metric creep because it feels safe—if you report everything, no one can accuse you of hiding something. But in practice, it dilutes focus and confuses readers.

Benchmarking Without Context

Comparing your performance to peers can be useful, but doing so without explaining differences in business model, geography, or methodology can mislead. A cement company and a software company will have vastly different carbon intensities; comparing them directly is meaningless. Yet many reports include peer comparisons without context, creating false impressions.

Copying the Leader

When a well-known company publishes a highly praised report, others rush to imitate its format and metrics. But what works for a market leader with a dedicated sustainability team may not work for a smaller company with limited resources. Copying without understanding the underlying rationale leads to reports that look good but lack substance.

The antidote to these anti-patterns is discipline: stick to material issues, provide context for comparisons, and build your report around your own strategy, not someone else's template.

Maintenance and Long-Term Costs of Credible Reporting

Building a trustworthy ESG report is not a one-time project. It requires ongoing investment in data infrastructure, training, and governance. These costs are often underestimated.

Data Quality Systems

Reliable ESG data depends on automated collection, internal controls, and regular audits. Companies that rely on manual spreadsheets are prone to errors and inconsistencies. Investing in ESG software or integrating data streams from ERP systems can cost tens of thousands of dollars annually, but the alternative is a report that cannot withstand scrutiny.

Staff Training and Turnover

ESG reporting requires specialized knowledge of frameworks, metrics, and assurance standards. When the person responsible leaves, institutional knowledge can disappear. Cross-training and documenting processes reduce this risk, but they take time. Budgeting for continuous learning is a long-term commitment.

Regulatory Drift

Reporting requirements are evolving rapidly. The EU's Corporate Sustainability Reporting Directive (CSRD), the SEC's climate rules, and ISSB standards are all changing the landscape. Companies must monitor these developments and adapt their reports accordingly. This is not a cost that can be deferred.

These costs are real, but they are investments in trust. A single reputational hit from a misleading report can cost far more in lost market value and legal fees.

When Not to Follow Standard Advice

Most ESG reporting guidance assumes a large, publicly traded company with dedicated resources. But for smaller firms, startups, or companies in early stages of their ESG journey, some standard advice may not apply.

When Full Materiality Is Impractical

A formal materiality assessment with extensive stakeholder surveys may be beyond the budget of a small company. In that case, a simpler approach—using industry-specific materiality lists from SASB or peer reports—can be a reasonable starting point. The key is to be transparent about the method used and to commit to deepening the assessment over time.

When Assurance Is Not Yet Possible

For a company with weak data systems, seeking assurance prematurely can be a waste of money. The auditor will find so many issues that the report may be delayed or qualified. It is better to first invest in data quality, then seek assurance on a limited set of metrics once the data is reliable.

When Following the Leader Is Dangerous

As mentioned earlier, copying a market leader's report structure can backfire. If your business model or stakeholder base is different, the metrics that matter to you may be different. Standard advice to “follow best practices” should be tempered with judgment: best practices for whom?

Knowing when to deviate from standard advice requires understanding your own context. It is not an excuse for low quality, but a recognition that one size does not fit all.

Open Questions and Common Concerns

Even with the best intentions, teams often have lingering questions about ESG reporting. Here we address a few of the most common ones.

How do we choose which metrics to report?

Start with your materiality assessment. If you haven't done one, use the SASB materiality map as a starting point. Choose a set of metrics that cover your most significant impacts and that you can measure reliably. It is better to report a few metrics well than many poorly.

What if our performance is poor?

Honesty is better than silence. If your emissions are rising, explain why—maybe due to acquisitions or production growth—and outline the plan to reverse the trend. Stakeholders respect transparency more than polished numbers. Acknowledging poor performance and showing a credible plan to improve builds trust.

How often should we update the report?

Annual reporting is standard, but some companies now publish quarterly updates on key metrics. The right frequency depends on your stakeholders' needs and your ability to produce reliable data quickly. If you cannot do quarterly, annual is fine, but consider adding a mid-year progress update on targets.

Should we include negative incidents?

Yes, if they are material. A safety incident, data breach, or environmental violation that is significant should be disclosed. Trying to hide it will almost always backfire when it comes to light. Include a description of what happened, the root cause, and the corrective actions taken.

How do we get started if we have no ESG report yet?

Start small. Pick one or two material topics, gather data, and publish a brief report. Use a recognized framework like GRI for structure. As you gain experience, expand the scope. The first report is never perfect, but it begins the journey of transparency.

Summary and Next Steps

Trust in ESG reporting is fragile, but it can be rebuilt by closing the three gaps: selective metrics, vague targets, and superficial assurance. The fixes are clear: use materiality to guide disclosure, set science-aligned targets, and apply assurance strategically. Avoid anti-patterns like metric creep and blind imitation. Invest in data systems and governance for the long haul.

Here are three actions you can take this week:

• Audit your current report for the three gaps. Does it omit any material metrics? Are your targets contextualized? Is assurance scope clearly stated?
• Conduct a mini materiality check with your top three stakeholders. Ask them what they find most useful—and what they find missing.
• Set one improvement goal for your next report. It could be adding a science-aligned target, obtaining assurance on a new metric, or publishing a data methodology note.

ESG reporting is not a static document; it is a conversation. By closing the gaps, you turn that conversation into one of genuine trust.
