Sustainability Report Assurance

Assurance of Sustainability Reports

Transparent reporting on sustainability issues such as social and environmental impacts is critical to safeguarding your company’s reputation. Bureau Veritas’ independent report assurance supports companies communicating their Environmental and Social Governance (ESG) practices to establish their credentials with stakeholders.

Today’s organizations face increased scrutiny of their business practices from all parties, including governments, external and internal stakeholders, investors, consumers and clients. Companies are expected to demonstrate complete transparency and communicate about their sustainability impacts thoroughly and openly. 

As an independent third party, Bureau Veritas can help businesses prove that information shared about their sustainability performance is accurate and bias-free. Beyond verifying data, Bureau Veritas report assurance allows companies to demonstrate best practices in sustainability reporting, giving a complete overview of company impacts.

Comply with regulatory requirements

In the European Union, the Corporate Sustainability Reporting Directive (CSRD) requires companies with >250 employees, >€40m net annual revenues or >€20m assets on their balance sheet, to publish regular reports on their environmental and social impacts. This is estimated to be 49,000 companies, including the EU-based subsidiaries of non-EU companies that meet this criteria, that must report according to the European Sustainabiltiy Reporting Standards (ESRS) from the start of 2024 (on their 2023 ESG performance data). Electronic data tagging to enable simpler comparison and independent third party assurance of these reports will be mandatory. The directive is being brought into local law in each member state from December 2022, with possible additional local requirements.

The EU is not the only jurisdiction introducing mandatory reporting, the Singapore Stock Exchange and the United Kingdom have already moved to align themselves with the Taskforce on Climate-related Financial Disclosures and the USA's Securities and Exchange Commission has introduced a similarly aligned proposal for enhanced climate related disclosures for investors to apply to all its listed companies. 

Ensure reliable data

The Global Reporting Initiative (GRI) framework helps organizations’ understand their impact on the economy, environment and society. It aims to increase accountability and enhance transparency by providing a score to business’ sustainability reports. Bureau Veritas supports companies seeking to prepare a report in compliance with the GRI framework, providing assurance for external sustainability data. 

Achieve credible reporting

With more companies publishing sustainability reports, ISO 26000  was created as a guideline for credible reporting and company accountability. It precisely defines areas of responsibility, makes the concept of corporate social responsibility more uniform, and structures the sustainability approach of big companies. Bureau Veritas offers assurance aligned with ISO 26000, giving companies a significant strategic advantage within a competitive marketplace. 

Prove reporting excellence

AccountAbility’s three AA1000 assurance standards are principles-based frameworks used by businesses, governments, and other public and private organizations. They hold companies accountable for sustainability management, performance and reporting. Bureau Veritas helps assure that companies’ reporting is aligned with the principles laid out in these standards, helping them demonstrate excellence in report assurance.

Demonstrate rigor in report assurance

Issued by the International Federation of Accountants, the International Standard on Assurance Engagements 3000 (ISAE 3000) sets the standard for assurance of non-financial information. The ISAE 3000 standard consists of guidelines for ethical behavior, quality management and performance. By providing assurance against this framework, Bureau Veritas enables organizations to prove the robust nature of their report assurance.

Improve communication with investors

The Sustainability Accounting Standard Board (SASB) includes 77 globally applicable industry-specific standards that enable businesses to identify, manage and communicate to their investors about financially material sustainability information. The SASB framework identifies the minimal set of financially material sustainability topics and their associated metrics for a typical company in a given industry. Bureau Veritas provides assurance that aligns with these requirements, enabling companies across sectors to communicate with investors in a detailed way.
