The global sustainability reporting landscape has undergone a fundamental shift — and it is now moving in two opposite directions. IFRS S1 and S2 are becoming mandatory across a growing number of jurisdictions, including Kenya, Rwanda and Nigeria, while the EU’s Corporate Sustainability Reporting Directive (CSRD) has been sharply narrowed by Directive (EU) 2026/470 of 24 February 2026, which confines mandatory reporting to undertakings exceeding both an average of 1,000 employees and EUR 450 million in net turnover. For African organisations supplying European multinationals, attracting international investors, or accessing development finance, a growing share of the pressure now comes from domestic regulators rather than European customers.

ISSB Standards: The New Global Baseline

The International Sustainability Standards Board (ISSB) issued IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) in June 2023. As at 26 February 2026 the IFRS Foundation counted 40 jurisdictions that had decided to use, or were taking steps to introduce, the ISSB Standards in their legal or regulatory frameworks — together roughly 60% of global GDP and more than 40% of global market capitalisation. Nine are African: Ethiopia, Ghana, Kenya, Nigeria, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe. The mandates are being driven as much by professional accountancy bodies and central banks as by securities regulators.

IFRS S1 requires entities to disclose material information about sustainability-related risks and opportunities affecting their cash flows and cost of capital. IFRS S2 specifically addresses climate risks, requiring disclosure of scope 1, 2, and 3 greenhouse gas emissions alongside scenario analysis. First-time preparers should note that the ISSB issued Amendments to Greenhouse Gas Emissions Disclosures in December 2025, effective for annual reporting periods beginning on or after 1 January 2027 with early application permitted — so an entity first reporting for 2027 applies the amended requirements.

CSRD: European Supply Chain Requirements

The EU’s CSRD is still significant for African businesses, but it now reaches far fewer of their customers. Directive (EU) 2026/470, adopted on 24 February 2026 and published in the Official Journal on 26 February 2026, replaced the earlier two-out-of-three size test with two cumulative thresholds and dropped listing status as a trigger: for financial years starting on or after 1 January 2027, mandatory reporting applies only to undertakings exceeding both an average of 1,000 employees and EUR 450 million in net turnover. Member States may also exempt undertakings that have fallen out of scope from reporting on financial years beginning between 1 January 2025 and 31 December 2026. Those that do report must still cover material sustainability impacts throughout their entire value chain — including African suppliers, manufacturers, and service providers.

An agricultural processor in Cameroon supplying a French food group, or a DRC mining company supplying a European industrial group, may still receive formal data requests covering carbon emissions, labour practices, governance, and deforestation risk — but which requests arrive now depends on the instrument behind them. Directive (EU) 2026/470 caps what a CSRD reporter may ask of the “protected undertakings” in its value chain, meaning those that did not exceed 1,000 employees in the preceding financial year. Deforestation risk is a separate regime: the EU Deforestation Regulation covers cattle, cocoa, coffee, palm oil, rubber, soy and wood and certain derived products, and applies from 30 December 2026 with simpler rules for micro and small operators, so cocoa and coffee exporters face due-diligence questions irrespective of the CSRD cap. Failure to respond adequately still risks removal from approved supplier lists.

What Organisations Should Do Now

For many African businesses, full ISSB or CSRD compliance is still not mandatory — but that is no longer true in the jurisdictions named above. Kenya requires public interest entities, including all listed entities, to apply the ISSB Standards for annual reporting periods commencing on or after 1 January 2027, large non-public-interest entities from 1 January 2028 and small and medium-sized entities from 1 January 2029. Rwanda’s phased roadmap is already running for listed entities and Tier I financial institutions, and National Bank of Rwanda Guidelines No 040/2024 of 25 November 2024 already mandate ISSB-based reporting for every financial institution it regulates. Nigeria requires public interest entities to apply IFRS S1 and S2 for annual reporting periods commencing on or after 1 January 2028, and small and medium-sized entities from 1 January 2030. For listed and regulated entities in these countries, preparation is now a compliance deadline rather than a prudent option.
