Every company listed on the Nairobi Securities Exchange will be legally required to publish sustainability disclosures aligned with international standards from 1 January 2027, under a national reporting roadmap now in its final preparatory phase.
- •The obligation covers two interlocking frameworks that must be published with audited financial statements: IFRS S1 requires companies to disclose how sustainability risks and opportunities affect enterprise value, cash flows, and cost of capital, while IFRS S2 requires mandatory reporting of Scope 1, Scope 2, and Scope 3 emissions.
- •NSE-listed companies sit within a broader class of Public Interest Entities facing the same obligation, alongside commercial banks, insurers, pension funds, CMA-regulated fund managers, and deposit-taking SACCOs.
- •The NSE and ICPAK have issued a joint market advisory this month setting a 30 June 2026 deadline for every listed company to submit a Sustainability Reporting Readiness Assessment covering board oversight, strategy integration, risk management processes, and emissions measurement systems. Issuers must also engage an independent assurance provider by the same date.

The assurance obligation escalates progressively: limited assurance from January 2028, reasonable assurance excluding Scope 3 from January 2029, and full reasonable assurance from January 2030.
Voluntary adoption has been thin since the phase opened in January 2024. KCB Group is the only NSE-listed financial institution confirmed to have published an IFRS S1 and S2-aligned sustainability report with limited assurance by Deloitte. No other Tier 1 bank or large-cap issuer has publicly confirmed equivalent readiness.
The connectivity requirement under IFRS S1 sharpens the challenge further. A standalone sustainability narrative is insufficient. Issuers must demonstrate how sustainability risks influence capital allocation, forward-looking financial assumptions, and information in their audited financial statements. This is a financial reporting obligation, not an ESG exercise.
The deadline arrives as listed companies post record corporate governance scores. NSE issuers scored 78.88% on the CMA's FY 2024/2025 governance scorecard, crossing into Leadership Rating for only the second time since assessments began in FY 2017/2018. All seven governance principles reached Leadership Rating simultaneously for the first time rising from 27 to 38 in a single year. Banking led sectors at 90.30%, with Agriculture the only sector rated Fair at 62.80%.
The gap between governance compliance and disclosure readiness remains wide, however. The CMA flagged that many issuers still failed to document mandatory director training hours. IFRS S1 and S2 demand quantitative emissions inventories, auditable internal controls, and robust data governance infrastructure: a materially higher bar.
NSE data shows close to 40% of foreign investors now consider ESG compliance a key factor in investment decisions.
