ESG data can expose greenwashing only when it is tied to a specific public claim, a defined reporting boundary and verifiable source records. A high sustainability score, falling emissions graph or “net zero” label is not conclusive unless the investigator understands what was measured and omitted.
Capture the exact claim
Preserve the advertisement, annual report, product page, image and date. Identify the audience and whether the claim concerns the whole company, one product, a fund or a future target. Words such as “green”, “carbon neutral”, “aligned” and “sustainable” may imply different things in different legal and commercial contexts.
For UK-regulated financial products, the FCA’s anti-greenwashing guidance says sustainability-related claims must be fair, clear and not misleading. Use the rule that applies to the product, jurisdiction and publication date rather than treating “greenwashing” as a universal legal category.
Define the reporting boundary
Record which subsidiaries, joint ventures, assets, countries and reporting periods are included. Check whether acquisitions, disposals or outsourced activities altered the comparison. A company can report lower operational emissions after selling a high-emitting asset even though the real-world activity continues elsewhere.
Map the corporate structure using the same discipline as our guide to investigating ownership chains. Compare the sustainability boundary with consolidated financial accounts and segment reporting.
Reconcile the numbers
Collect the raw metric, unit, methodology, base year, restatements and assurance statement. For climate claims, separate absolute emissions from intensity measures and Scope 1, Scope 2 and Scope 3. Check whether market-based electricity figures rely on certificates, whether avoided emissions are mixed with inventory emissions, and whether offsets are presented separately.
IFRS S2 requires disclosures about climate targets, the metrics used to monitor them, revisions and performance. The IFRS Foundation’s IFRS S2 supporting material helps establish a transparent benchmark, though local adoption and legal requirements must still be verified.
Test targets against capital allocation
Compare published commitments with capital expenditure, research spending, production forecasts, lobbying, executive incentives and board papers. A distant target deserves more scrutiny if current investment expands the activity the target promises to reduce. Our analysis of why ethics programmes fail in practice explains the same gap between stated policy and operational incentives.
Check comparability and assurance
Do not rank companies until definitions and boundaries are comparable. Record missing fields rather than silently treating them as zero. Read the assurance scope carefully: limited assurance over selected metrics is not an audit of every environmental claim. Recalculate ratios and preserve the source spreadsheet and formula.
Malta News Online’s reporting on calls for measurable outcomes from Project Green provides relevant local context. Treat it as a secondary lead and verify budgets, deliverables and environmental results against official project and procurement records.
Build a claim-to-evidence matrix
For each claim, list the implied meaning, reported metric, boundary, primary source, recalculation, contradictory evidence and company response. Classify the result as supported, incomplete, inconsistent or misleading under the applicable rule. Do not infer intent merely from poor data.
The final report should publish the method and limitations, explain changes in definitions and give the company a precise opportunity to correct the record. ESG data is most powerful when it turns a broad impression into a narrow, reproducible test.
