ESG Reporting Is Now Mandatory for NSE Companies

In 2023, the Capital Markets Authority (CMA) issued its ESG Disclosure Guidance, making environmental, social and governance reporting mandatory for all companies listed on the Nairobi Securities Exchange (NSE). This isn’t just about sustainability—it’s about investor confidence, regulatory compliance, and long-term valuation.

Yet many firms are unprepared. They treat ESG as a PR exercise, not a governance requirement. The result? Incomplete disclosures, unsubstantiated claims (“greenwashing”), and heightened scrutiny from regulators and shareholders.

What Does the CMA Require?

The guidance covers three pillars:

• Environmental: Carbon emissions, water use, waste management
• Social: Diversity, employee welfare, community impact
• Governance: Board diversity, anti-corruption policies, risk oversight

5 Steps to Get Ready

1. Appoint an ESG Champion – Ideally, someone reporting to the board.
2. Conduct a Materiality Assessment – Identify which ESG issues matter most to your business and stakeholders.
3. Map Data Sources – Where will you get emissions data? Employee turnover stats? Supplier ethics info?
4. Align with Global Frameworks – Use GRI, SASB, or TCFD to structure your report.
5. Engage an Independent Assurer – An audit firm with ESG expertise can validate your claims and boost credibility.
