Increase credibility with a Sustainability Report

In the context of reporting, verification and assurance refer to the external review of a report. The goal of the review, also called an audit, is to ensure the resilience, accuracy, and trustworthiness of the published information to create added value for stakeholders and the company.

The Global Reporting Initiative (GRI), which publishes the most widely used international framework for sustainability reports, recommends external assurance. According to the GRI, the global trend of sustainability report assurance has increased, with half of published reports already undergoing an external audit - and the trend is rising.

Assurance of GRI reports, Global Compact, and ESRS report

Whether your sustainability report is based on the GRI standards, the Global Compact principles, ISO 26000, the SDGs, the German Sustainability Code, or other reporting standards, DQS Inc. is your partner for the external assurance audit. In addition to a review of the full report, it is also possible to request assurance on selected key figures or parts of the report.

In principle, the external assurance of sustainability reports is suitable for companies of any size and industry. It is particularly relevant for organizations that are in the eye of the public, such as listed companies, public organizations and companies that underlie specific legal requirements.

DQS Inc. – your licensed assurance provider

In order to increase the quality of assurance procedures and ensure a certain degree of comparability, the British non-profit organization AccountAbility has published a standard for the assurance of sustainability reports, the AA1000 Assurance Standard (AS). The standard does not impose any requirements on the report itself but describes the actual assurance process. As an officially licensed provider, DQS Inc. is your partner for objective, independent, and internationally recognized assurance statements.

Level of Assurance

During the planning phase, the level of assurance must also be defined. This is the degree of assurance that the audit provides:

Medium level of assurance: your information is checked for plausibility. The audit focuses on internal evidence and on the management level.
High level of assurance: the evidence gathering process is more extensive here. The review is not limited to internal evidence and includes external sources. All levels of the organization are surveyed on a random basis.

What is the verification process?

First, you discuss your organization, your approach to sustainability reporting and the objectives of the assurance engagement. Based on these discussions, you will receive an individual quote tailored to the needs of your company or organization.

The assurance audit consists of two parts: The document review and the audit. The duration of the assurance depends on the scope, the scope of the report, and the selected assurance type and level. During the final meeting, our auditors explain all findings to you, give you feedback, and plan further steps together.

After the assurance process is complete, we prepare an assurance statement that is published with the sustainability report.

What does the assurance of a sustainability report cost?

The cost of an external assurance depends on the scope, the complexity of the report, and the type and level of assurance selected. We are happy to make you an individual quote for your organization.
