Crossing your fingers without assurance is not a good strategy
“When assurance isn’t legally required, the choice is simple: invest a modest amount in independent verification, or accept the risk that sustainability claims are flawed, misleading or incorrect. The cost of assurance is minor compared to the risk of public embarrassment, fraud allegations and greenwashing scandals.”
Pauline Bailley, Head of ISO Certifications at Speeki
Six reasons why a ‘fingers crossed’ strategy is unwise
Investors won't trust unverified data
Institutional investors and ESG-focused funds increasingly expect independent assurance over sustainability disclosures. Self-reported ESG data is viewed as unreliable and introduces information risk that sophisticated investors will not accept.
This affects the cost of capital. Companies with assured sustainability data often secure better financing terms, including access to green bonds and sustainability-linked loans. Those without assurance face greater scrutiny and potentially higher borrowing costs.
In competitive capital markets, unverified reporting can mean losing funding to competitors with credible, assured disclosures.

Greenwashing allegations can destroy your reputation
Under heightened ESG scrutiny, unverified sustainability claims are met with scepticism. Investors, NGOs, journalists and regulators actively challenge exaggerated or unsupported statements.
Without independent assurance, a single challenge can escalate into greenwashing allegations, attracting media attention, customer backlash and regulatory scrutiny.
The reputational damage far outweighs any short-term savings from avoiding assurance. Once trust is lost, it is difficult to restore.
You're handing competitors a market advantage
In many sectors, customers, supply chain partners and tender processes require verified sustainability credentials. Operating without independent assurance creates a competitive disadvantage.
Large companies increasingly expect suppliers to provide assured ESG information as part of procurement. Without verification, sustainability claims carry less credibility than those of competitors that have invested in assurance, affecting contracts, partnerships and market position.
Competitors with assured disclosures are not just meeting expectations. They are strengthening their commercial position.
You're gambling with regulatory compliance
Sustainability reporting requirements are tightening globally, and regulators are increasing scrutiny of ESG disclosures. Even where assurance is not yet mandatory, regulatory direction points clearly towards verification becoming a requirement.
Delaying assurance means building reporting systems without external validation. When assurance becomes mandatory, organisations often discover weaknesses in how data has been measured and reported.
Early adoption of independent verification helps establish compliant processes from the outset, rather than requiring remediation of years of potentially non-compliant reporting.
Internal teams have blind spots you can't see
Internal teams are too close to the data and assumptions behind sustainability reporting, which creates blind spots.
Bias, organisational culture and pressure to present positive results can influence how data is collected and disclosed, even with strong controls.
Independent verifiers bring an external perspective and no stake in the outcome. They identify methodological errors, boundary inconsistencies and data gaps that internal teams miss.
Without external verification, organisations assume internal checks are sufficient – often discovering weaknesses only after public disclosure, when correction is far more difficult.
