ESG assurance gives stakeholders confidence that your sustainability data, disclosures and compliance claims are accurate, complete and supported by evidence. Independent review reduces the risk of material errors, greenwashing allegations and regulatory scrutiny, while strengthening the information used by management, investors, customers and other value chain partners. It also reveals weaknesses in data ownership, calculation methods, and documentation, helping you improve internal processes and report with greater confidence.

Any organisation that publishes sustainability information or relies on ESG data for decisions can benefit from assurance. It is especially relevant for companies reporting under the CSRD or VSME, businesses responding to investor or customer data requests, and organisations that want to publish substantiated sustainability claims. Assurance is also valuable for companies with complex Scope 3 emissions, international value chains, tender requirements or regulatory obligations under frameworks such as CBAM and the EUDR.

The best time to prepare is before the reporting period or assurance engagement begins. Early preparation gives you time to define reporting boundaries, assign data owners, document methodologies, strengthen controls and resolve evidence gaps before figures and disclosures are finalised. This is particularly important ahead of a first CSRD or voluntary report, major stakeholder request, tender, or the publication of emissions and compliance claims. An early readiness review helps prevent last-minute corrections, delays and additional costs.

Yes, in addition to GHG accounting, ESG reports and compliance under CBAM and the EUDR, we can tailor assurance to other environmental, social and governance disclosures and claims. This may include energy and resource data, value-chain information, policies, targets, performance indicators, due diligence records and selected disclosures under recognised reporting or regulatory frameworks. We first define the subject matter, applicable criteria, intended users and required level of assurance, and then design a proportionate, evidence-based engagement around your needs.

Our Sustainability as a Service model makes assurance readiness a continuous process rather than a one-off exercise before publication. For a fixed monthly fee, our specialists act as an extension of your team, helping maintain evidence trails, monitor controls, update methodologies, prepare data owners and address findings throughout the year. The service is modular and tailored to your reporting cycle and assurance scope, giving you ongoing access to expertise without building a full in-house assurance function. This keeps your ESG information reliable, traceable and ready for publication.
