Luxembourg's Commission de Surveillance du Secteur Financier (CSSF) published an update outlining its supervisory priorities on sustainable finance across credit institutions and investment firms, the asset management industry and issuers. The programme centres on supervising sustainability-related transparency and disclosures, embedding climate, nature and broader ESG risks into governance and risk management, and checking that sustainability claims and documentation remain consistent and credible. For banks and investment firms, supervision will continue to focus on Sustainable Finance Disclosure Regulation (SFDR) obligations via the revised long form report framework, with self-assessment responses assessed in prudential supervision and used to support enforcement measures where appropriate. On-site inspections of depositary entities will continue to incorporate monitoring of ESG-related investment restrictions, while banking supervision will keep reviewing climate and nature-related risk integration against CSSF expectations and the European Banking Authority guidelines as implemented in Luxembourg, including through inspections that integrate ESG aspects and potential ESG-focused reviews. The CSSF will also continue supervising MiFID sustainability rules using a proportional approach that reflects firms’ circumstances and remaining regulatory uncertainties. For investment fund managers, the CSSF will monitor compliance with SFDR, the SFDR regulatory technical standards and the EU Taxonomy, drawing on ESMA guidance including fund naming guidelines, and will prioritise checks on sustainability risk integration in organisational arrangements, the quality and consistency of pre-contractual, periodic and website disclosures, and portfolio analysis to confirm holdings match the fund’s name, objectives and disclosed characteristics. On issuer reporting, the CSSF will continue guiding companies that voluntarily publish sustainability statements aligned with the European Sustainability Reporting Standards while Corporate Sustainability Reporting Directive changes are finalised at EU level and transposition in Luxembourg remains pending, including by publishing fact-finding results and conducting bilateral exchanges. Work will also continue through ESMA-led European common enforcement priorities for annual reports and, in prospectus approvals, through contributions to EU-level development of minimum ESG information requirements and related Q&As and guidelines, with priorities subject to adjustment as risks and EU rules evolve, including the ongoing review of SFDR and the Pillar 3 disclosure implementing technical standards.
