The Danish Financial Supervisory Authority has published a set of observations from its review of initial sustainability reporting issued alongside 2024 annual reports by 21 financial firms. The observations are intended to help firms improve upcoming reporting and to support the authority’s ongoing supervisory guidance. The review focused on how in-scope firms explained their double materiality assessments, and included a deeper dive into key parts of the reporting from five selected firms. Work concentrated on disclosures expected to remain relevant even as the European Union revises the Corporate Sustainability Reporting Directive, known as CSRD, through the Omnibus I simplification package, including information on firms’ climate impacts. The authority indicated that its supervisory approach will emphasise guidance on meeting the data and organisational demands of CSRD sustainability reporting while the EU rule set is being revised.
