Nigeria will require large public interest entities to begin mandatory sustainability reporting from 2027 under a phased regulatory framework designed to align the country’s capital markets with international environmental, social and governance (ESG) disclosure standards. The reforms, announced by the Securities and Exchange Commission (SEC) at the 2026 Financial Institutions Training Centre (FITC) Sustainability and ESG Conference in Lagos, represent one of the most significant shifts in corporate reporting requirements since the adoption of international financial reporting standards and signal Nigeria’s intention to position its financial markets within the rapidly evolving global sustainable finance landscape.
According to SEC Director-General Dr Emomotimi Agama, the implementation will begin with voluntary adoption by early adopters and large public interest entities before becoming mandatory in 2027. The reporting requirements will subsequently extend to other public interest entities in 2028, with small and medium-sized enterprises expected to comply by 2030. The framework is being aligned with the International Sustainability Standards Board (ISSB), including IFRS S1 and IFRS S2, which are increasingly emerging as the global benchmark for sustainability-related financial disclosures.
The move reflects a broader transformation in global capital markets, where investors increasingly assess companies not only on financial performance but also on their ability to manage climate-related risks, governance quality, human capital and broader sustainability issues. According to Agama, sustainability disclosure is rapidly becoming a prerequisite for accessing international investment, with institutional investors treating ESG performance as a core component of capital allocation decisions rather than a voluntary corporate responsibility exercise.
The reforms also coincide with continued expansion of Nigeria’s capital markets. According to the SEC, market capitalisation has increased from approximately ₦130 trillion to nearly ₦160 trillion following recent market reforms, while assets under management have surpassed ₦9 trillion. Regulators view stronger sustainability reporting as a mechanism for reinforcing investor confidence, improving market transparency and attracting longer-term international capital into Africa’s largest economy.
Beyond corporate disclosure, the SEC outlined plans to deepen sustainable finance by promoting infrastructure bonds, green bonds, municipal bonds and infrastructure-focused investment funds. The commission also intends to encourage investment in Nigeria’s emerging blue economy while supporting financing for renewable energy and electricity infrastructure through green energy bonds, project finance instruments and public-private partnerships.
These financing mechanisms are expected to play an increasingly important role as African governments seek to bridge persistent infrastructure deficits while responding to climate adaptation and energy transition priorities. Mobilising private capital through domestic financial markets remains a strategic objective across the continent, particularly as public finances continue to face pressure from debt servicing, population growth and infrastructure demand.
The launch of the Nigerian Exchange (NGX) Impact Board was highlighted as another milestone in expanding sustainable investment opportunities. The platform is intended to improve visibility for companies delivering measurable environmental and social outcomes while creating additional pathways for investors seeking assets aligned with sustainability objectives.
Discussions at the conference reflected a broader shift in African business thinking, with sustainability increasingly framed as an economic competitiveness issue rather than solely an environmental obligation. FITC Managing Director and Chief Executive Officer Dr Chizor Malize said sustainability has evolved from a compliance requirement into a strategic driver of business resilience, investment attractiveness and long-term economic growth. She described the conference as moving stakeholders “from conversation to commitment” as sustainability considerations become embedded across financial systems.
Governance emerged as a recurring theme throughout the discussions. Professor Fabian Ajogwu, Chairman of the FITC Advisory Board, argued that governance remains the foundation of sustainable development and called for Africa to become a contributor to global sustainability standards rather than relying exclusively on externally developed frameworks. According to Ajogwu, governance failures continue to impose significant economic costs across the continent, while climate-related disruptions increasingly threaten infrastructure, agricultural production and economic stability despite Africa contributing less than four per cent of global greenhouse gas emissions.
Examples of regional collaboration were also cited as models for sustainable industrial development, including partnerships involving Morocco’s OCP Group and the Nigeria Sovereign Investment Authority to strengthen agricultural productivity through technology and investment. Such initiatives demonstrate how sustainability can support productive sectors while contributing to food security and economic diversification.
Delivering the conference keynote address, MTN Nigeria Foundation Chairman Mosun Belo-Olusoga argued that the debate over whether sustainability matters has effectively ended, with implementation now becoming the central challenge for businesses and policymakers. She noted that investors increasingly evaluate companies based on governance standards, operational resilience and their capacity to manage environmental and social risks alongside profitability.
Belo-Olusoga observed that Africa possesses significant comparative advantages within the global transition to a lower-carbon economy, including extensive renewable energy resources, substantial agricultural potential and reserves of critical minerals required for clean energy technologies. However, she argued that realising these opportunities will depend on translating strategic ambitions into effective policy implementation, institutional reform and investment mobilisation.
She identified several priorities for African businesses and governments, including integrating sustainability into corporate strategy, strengthening governance, mobilising domestic capital through green finance instruments, investing in human capital and expanding partnerships across renewable energy, digital technology and climate-smart agriculture.
The introduction of mandatory sustainability reporting in Nigeria also has wider implications for African financial markets. As more countries adopt ISSB-aligned disclosure frameworks, greater consistency in ESG reporting could improve comparability between companies, lower information asymmetries for investors and strengthen the credibility of African capital markets. Enhanced reporting standards may also support the development of regional sustainable finance markets capable of financing infrastructure, industrialisation and climate resilience projects across the continent.
For African economies seeking to attract greater private investment while navigating climate risks and development challenges, the convergence of financial regulation with international sustainability standards represents more than a compliance exercise. It reflects an evolving recognition that governance quality, environmental performance and transparent disclosure are becoming integral components of long-term economic competitiveness and access to global capital. As sustainability reporting becomes embedded within financial regulation, the ability of African businesses to demonstrate measurable ESG performance is likely to play an increasingly influential role in shaping investment decisions, corporate valuations and the continent’s broader development trajectory.
