ESG assurance

Combine both significant auditing and assuring experience with a deep understanding of ESG matters to provide you and your stakeholders with high-quality assurance projects.

Our team of experts combines expertise in auditing and assurance services with an understanding of ESG legislation to provide you with high-quality non-financial verification services. With our extensive expertise in sustainability issues, we can help you ensure trust with your stakeholders as well.

Not only for investors, but also for other stakeholders, the topic of ESG is coming to the forefront, so verification of non-financial information by an independent party is becoming much more important. The legislation on sustainability reporting itself, specifically the Corporate Sustainability Reporting Directive (CSRD), even requires external verification of this information. 

The emphasis on accurate, comparable and reliable reporting makes assurance in sustainability reporting more important than ever before.

Our company has extensive experience not only in the preparation of sustainability reports, but also in CSRD reporting verification services. We have gained this experience by working with companies that were required to report for the 2024 financial year.

At Deloitte, we offer a broad portfolio of assurance services – in addition to CSRD disclosures, we also verify emissions reported under the GHG protocol and provide further verification of ESG information according to the client's individual needs.
