Sustainability performance data is a vital source of information for anyone seeking a holistic understanding of an organization’s activities. Independent assurance adds credibility and can help identify areas for improvement while signaling a desire for transparency and meaningful reporting.

From climate change and nature and biodiversity to diversity and inclusion, stakeholders are increasingly interested in business performance in areas that cannot be captured by financial metrics alone. Sustainability reporting helps management and external stakeholders see how an organization interacts with society and the planet.

Presenting credible information has become an essential part of corporate reporting. External stakeholders including investors, customers, government, future employees seek reliable and accurate information on sustainability performance, from carbon emissions to community engagement.

Furthermore, with the introduction of the EU Corporate Sustainability Reporting Directive (CSRD) which came into effect in January 2024, sustainability reporting for those organizations affected now has a wider scope and sharper focus on business impacts. As well as outlining a comprehensive framework and specific guidelines on what and how to report, it also states organizations will require independent assurance of their sustainability report and metrics.
