South Africa’s Financial Sector Conduct Authority (FSCA) has signaled a decisive shift in how it will treat sustainability claims across the financial sector, moving ESG compliance from voluntary guidance into enforceable conduct standards.

All sustainability claims made by financial firms are now expected to be factually accurate, free of misleading language, and communicated clearly. The FSCA has warned that vague or inconsistent claims risk undermining market confidence and elevating the likelihood of greenwashing, social washing, and impact washing.

At the corporate level, the FSCA is moving to introduce mandatory sustainability disclosure requirements for large, listed entities, starting with climate-focused reporting aligned to the International Sustainability Standards Board (ISSB) framework, specifically IFRS S1 and IFRS S2. The regulator notes that improved reporting standards will enhance market integrity, comparability, price discovery, and the allocation of capital.

The FSCA’s Sustainable Finance Update Report 2026 outlines progress made across its five programme pillars: Green Finance Taxonomy, Disclosure and Reporting, Market Development, Active Ownership, and Consumer Education.

For financial institutions, the practical implication is that internal ESG governance, reporting infrastructure, and alignment with IFRS S1 and S2 are no longer optional preparation; they are the baseline. The FSCA’s direction is unambiguous: sustainability claims now carry the same legal and reputational weight as any other financial disclosure.
