Recent Developments in Financial Services ESG Regulations

Despite this momentum, there is a lack of uniformity in regulatory approaches, with financial services regulators at differing stages of implementing ESG frameworks. This variability presents challenges for institutions operating internationally, emphasizing the need for vigilance in tracking regulatory developments.

This report synthesizes key ESG regulatory updates from several regions including the UK, France, the EU, the Netherlands, the US, and Australia.

**Highlights from Recent Developments**

Challenger banks have embraced sustainability as a core aspect of their identity, attracting customers while also facing regulatory scrutiny designed primarily for larger entities. One major risk for these banks is greenwashing. In the UK, the Financial Conduct Authority (FCA) has mandated that sustainability claims must be fair, clear, and not misleading since May 2024. Similarly, EU regulators are increasingly focused on ensuring that claims about the treatment of customer deposits are substantiated.

Many small and medium-sized enterprises (SMEs) and retail borrowers do not provide emissions data, leading challenger banks to rely on fintech partners for ESG information, which raises concerns about the data’s reliability and the liability in case of discrepancies.

UK and EU regulators require that climate risks be incorporated into governance frameworks and risk assessments. Concentrated lending activities expose banks to physical risks like flooding, as well as transition risks due to evolving energy standards.

Changing disclosure rules on both sides of the English Channel have prompted firms to stay alert to the applicable regulations. The EU has revised its corporate sustainability reporting framework, while the UK has introduced new reporting standards aligned with international norms set by the International Sustainability Standards Board (ISSB).

To prepare for regulatory compliance, smaller firms should implement practical measures including maintaining documentation for sustainability claims, conducting due diligence on ESG data sources, integrating climate risk analysis into their frameworks, and establishing clear senior management accountability for ESG initiatives.

**UK Update**

On September 30, 2026, the FCA issued Policy Statement 26/19 detailing changes to align the sustainability disclosures of listed companies with UK Sustainability Reporting Standards (UK SRS). This follows a consultation period initiated on January 30, 2026, where feedback led to refinement of the proposals. The FCA emphasized that the adjustments made are generally not substantial and outlined the importance of a comply or explain framework for disclosures, which aims to enhance the quality of sustainability reporting.

The final rules will take effect starting January 1, 2027, with transitional relief granted for specific disclosure requirements. The FCA plans to conduct a webinar on October 19, 2026, to support issuers in understanding the new guidelines.

**EU Update**

On September 10 and 16, 2026, the European Parliament voted to simplify sustainability-related disclosures under the Sustainable Finance Disclosure Regulation (SFDR), resulting in broad bipartisan support. The revised regulation aims to clarify sustainability claims and reduce administrative burdens.

On September 22, the EU Platform on Sustainable Finance submitted its response regarding the Taxonomy Disclosures Delegated Act, providing recommendations to refine key performance indicators for sustainability reporting and improve group reporting criteria.

**France Update**

The Autorité des Marchés Financiers (AMF) on October 1, 2026, released findings on the credibility of transition plans related to the SFDR revision, emphasizing the need for measurable objectives and clarity in sustainability reporting.

**The Netherlands Update**

On September 24, 2026, the Authority for Consumers & Markets established stricter guidelines on sustainability claims following the European directive directed at empowering consumer transition towards sustainable options.

**Australia Update**

The Australian Securities and Investments Commission (ASIC) noted positive progress in sustainability reporting among Group 1 entities as of September 21, 2026. Despite improvements, ASIC called for better forward-looking disclosures and highlighted essential compliance actions.

**United States and Other International Updates**

As of this report, there are no new updates from the SEC, CFTC, or other international regulators during this period.
