Why verify

More confidence in the data people rely on.

Independent verification adds an external assessment to your emissions reporting. It also identifies weaknesses your organisation can address in the way it collects, calculates and manages information.

The marketing case

Verification as a commercial advantage.

For marketing and communications directors, ISO 14064-3 verification turns carbon reporting from a potential reputational risk into a defensible basis for brand trust and competitive positioning.

Regulatory exposure

Reducing greenwashing risk and regulatory fines.

Environmental claims are under closer scrutiny than ever. Since April 2025, the Digital Markets, Competition and Consumers Act 2024 has allowed the Competition and Markets Authority (CMA) to fine businesses up to 10% of global turnover for breaches of consumer law, including misleading environmental claims. The Advertising Standards Authority (ASA) continues to rule against unsubstantiated claims such as “carbon neutral” and “eco-friendly”.

When the accountancy firm Menzies analysed 53 ASA greenwashing rulings issued between 2020 and 2025, it found that 81% could have been wholly or partly avoided with proper evidence and ESG assurance. Menzies analysis

ISO 14064-3 verification gives marketing teams defensible evidence for emissions claims: figures traceable to verified data and a documented methodology.

Customer trust

Turning verified data into trust.

Scepticism towards corporate environmental claims is well documented, and self-declared claims no longer carry the weight they once did. Independent verification gives people a reason to believe what you report.

“Independent verification of your environmental and sustainability data is a vital tool for avoiding or countering such accusations.”
CDP, on greenwashing and green hushing, in The business benefits of third-party verification of environmental data (2023), p. 4. Source and verification resources

ISO 14064-3 verification gives you something self-assessment cannot: an internationally recognised, independently checked basis for your emissions claims. It sets your messaging apart from competitors still relying on unsubstantiated assertions.

Commercial advantage

Winning tenders and protecting contract value.

In business-to-business markets, carbon data is increasingly part of procurement. Large customers and public-sector buyers need emissions data from their suppliers for their own Scope 3 reporting, and many score environmental performance in tenders. Suppliers who can show independently verified figures are easier to assess and easier to trust.

A verification statement can support customer requests, tender submissions and stakeholder reporting where it meets the intended recipient’s requirements. It shows what was assessed and the level of assurance obtained. We agree the period, boundary, criteria, coverage and outputs before the work begins, so the statement fits its purpose.

Beyond compliance

Verification as a management tool.

Organisations that treat verification only as a compliance exercise miss much of its value. The structured review of data sources, calculation methods, boundary decisions and assumptions surfaces issues that internal teams are too close to see.

Every verification produces a findings report identifying misstatements, areas for improvement and corrective actions. Over successive cycles, it becomes a record of how your carbon management is maturing.

The organisations that get the most from verification use the findings as a management input, feeding improvements into operational planning, procurement decisions and investment cases.

Value for your team

Find issues before the deadline gets close.

Our free readiness review brings testing forward. Your team receives findings while it can still gather evidence and implement corrections. Formal verification then examines the complete reporting period, and you have a documented record that the figures were independently checked. Who carries the risk
