The IESBA strongly welcomes the CEAOB proposal, in the sense that it will allow the EU to fulfil the unregulated but already mandatory activity of sustainability assurance.
It is, however, critical that these guidelines include robust ethics and independence requirements to ensure that the assurance framework operates with quality, integrity and effectiveness.
Starting from financial years beginning on or after 1 January 2024, large companies in the EU are required to draw up sustainability statements in accordance with the European Sustainability Reporting Standards (ESRS). These statements are required to be subject to an assurance engagement by statutory auditors or other assurance services providers.
To prevent fragmentation and promote consistency in practices until the European Commission’s (EC) adoption of an assurance standard at EU level by 1 October 2026, the EC has invited the CEAOB to develop non-binding guidelines regarding limited assurance on sustainability reporting.
