As October draws in and Halloween decorations begin to appear, financial services companies are reminded that while masks and illusions are acceptable for the season, they have no place in sustainable finance. Across the European Union (“EU”), regulators are increasingly unmasking misleading environmental, social and governance (“ESG”) claims, and under the Sustainable Finance Disclosure Regulation (“SFDR”), such “greenwashing” practices are facing heightened scrutiny. For firms managing or marketing investment products, the risk of overstating sustainability credentials has never been more significant and the consequences are far from a harmless scare.
In recent years, the European supervisory landscape has undergone a marked transformation. The European Securities and Markets Authority (“ESMA”) has moved from issuing general guidance to promoting tangible enforcement actions, encouraging national competent authorities (“NCAs”) to proactively assess sustainability-related disclosures. The focus has shifted from voluntary alignment to evidence-based accountability, requiring firms to substantiate every sustainability statement with data, documentation, and demonstrable governance.
At the EU level, the European Commission has also signalled that while the SFDR framework may evolve, supervisory expectations will not wane. The Commission’s 2025 call for evidence on the future of SFDR reflects an effort to simplify and clarify disclosure obligations, yet both the Commission and the European Supervisory Authorities have made it clear that firms must continue to comply rigorously with existing rules. ESMA’s thematic work has reinforced that sustainability claims must be credible, consistent and verifiable, in short, no “tricks” are tolerated when it comes to transparency.
In Malta, the Malta Financial Services Authority (“MFSA”) has equally demonstrated its commitment to ensuring credible ESG disclosures. Through its supervisory priorities and guidance notes, the MFSA has aligned itself with broader EU initiatives, particularly in strengthening oversight of SFDR implementation. Maltese firms authorised under the Investment Services Act are now expected to maintain clear governance structures and to substantiate all sustainability statements made in pre-contractual documents, marketing materials, and websites. The Authority has also shown a growing focus on the management of third-party ESG data providers and the consistency of sustainability messaging across various disclosures. The message is clear: the MFSA will not hesitate to step in where sustainability representations appear to be more decorative than genuine.
The legal and compliance vulnerabilities that often lead to enforcement action typically arise from several interconnected factors. Frequently, marketing language goes beyond what can be evidenced by internal investment processes or data. In other cases, governance frameworks fail to ensure proper review of sustainability claims before publication. Even more commonly, inconsistencies emerge between different documents for example, where the sustainability characteristics described in a prospectus differ from those presented on a firm’s website or in periodic reports. Furthermore, firms sometimes underestimate the risk of relying heavily on external ESG data providers without sufficient due diligence or contractual oversight. These gaps can collectively expose firms to enforcement, particularly when regulators perceive a pattern of insufficient controls or documentation.
To mitigate these risks, firms should take a proactive and integrated approach to ESG compliance. Every sustainability claim, whether in an Article 8 or Article 9 product, should be traceable to a well-documented investment process supported by contemporaneous evidence. Governance structures should assign clear responsibility for the accuracy of ESG disclosures, and senior management should provide oversight at both committee and board levels. Equally, ESG data and methodologies should be validated through due diligence, ensuring that external sources are reliable and auditable. Firms should also conduct regular reconciliations of their disclosures to eliminate inconsistencies across public documents, marketing materials, and investor communications.
Ultimately, the evolving enforcement landscape is a reminder that in sustainable finance, transparency is not a seasonal costume but a year-round obligation. Regulators across the EU, including the MFSA, are now well-equipped to see through superficial sustainability narratives. This Halloween, as others don masks and carve pumpkins, financial services companies would do well to lift the mask from their own sustainability claims, ensuring that what lies beneath can withstand regulatory scrutiny. True sustainability, after all, is no trick, it is the real treat.
