Sustainability is increasingly moving from the specialist functions of African companies into core business decisions, as rising climate risks, tighter disclosure expectations, changing investor demands and pressure on operating costs force executives and boards to treat environmental, social and governance issues as matters of financial and operational performance. The shift was highlighted this week by Sylvia Mulinge, Chief Executive of MTN Uganda, who said sustainability should not be delegated to a single department but embedded across investment, network resilience, customer protection, governance, risk management and day-to-day business decisions.
Mulinge’s comments followed the release of MTN Uganda’s 2025 Sustainability Report, the company’s first report aligned with the International Financial Reporting Standards Sustainability Disclosure Standards, IFRS S1 and IFRS S2. The report was independently assured by Ernst & Young, while the company said it had reduced Scope 1 and Scope 2 greenhouse-gas emissions by 45 percent against its 2021 baseline and was working towards net-zero emissions by 2040.
The significance of the development extends beyond one telecommunications company. For African businesses, sustainability is increasingly becoming part of the infrastructure of corporate decision-making as climate exposure, regulation, capital-market expectations and resource constraints affect the cost and resilience of operations. What was once treated primarily as corporate social responsibility is increasingly being assessed through enterprise risk, investment planning, supply-chain management and the ability of companies to retain access to capital and markets.
According to MTN Uganda, its sustainability framework now covers network investment, climate action, financial and digital inclusion, governance, partnerships and value creation. The company reported 24.2 million subscribers in 2025, contributed Shs1.6 trillion in taxes, duties and levies, spent Shs1 trillion with local suppliers and invested Shs549.4 billion in capital expenditure. Those figures illustrate why sustainability decisions in large African businesses increasingly have implications beyond the companies themselves: they affect employment, public revenues, suppliers, infrastructure investment and access to essential services.
Telecommunications provides a particularly useful example because its sustainability risks are closely connected to physical infrastructure. Mobile networks depend on electricity, backup power systems, data infrastructure, towers and extensive supply chains. Climate-related disruption, rising energy costs or unreliable power can therefore affect both operating expenditure and service reliability. For a business whose infrastructure supports financial transactions, healthcare, education and commerce, network resilience can also become an economic resilience issue.
The same logic applies across sectors. For banks, sustainability risks can influence lending portfolios, collateral values and exposure to climate-sensitive industries. For manufacturers, energy costs, water availability, waste management and supply-chain disruption can affect production. For agriculture, climate variability can alter yields, insurance costs and commodity prices. In mining and energy, environmental regulation, community relations and carbon exposure increasingly intersect with investment decisions and the ability to secure financing.
This is helping change the question boards ask about sustainability. Instead of deciding how much money should be allocated to environmental or social initiatives, companies are increasingly being required to identify which sustainability-related risks and opportunities could affect their financial prospects and how those issues should influence strategy.
That shift is central to IFRS S1 and S2. The standards, developed by the International Sustainability Standards Board, are designed to bring sustainability and climate-related information closer to the information investors need when assessing a company’s prospects. MTN Uganda’s early alignment with the standards therefore places its reporting within a wider transition in African capital markets, where sustainability information is increasingly expected to be decision-useful rather than confined to voluntary corporate reporting.
The development also reflects a broader movement among African regulators and markets toward more structured sustainability disclosure. MTN Group’s 2025 Climate Reporting notes that several markets, including Uganda, Nigeria, Ghana and Rwanda, have published or moved toward disclosure roadmaps aligned with the ISSB standards. For companies operating across several African jurisdictions, this creates a growing need to develop consistent systems for collecting, verifying and governing non-financial data alongside conventional financial information.
The implications for finance departments are significant. Sustainability data increasingly has to meet standards of accuracy, governance and assurance comparable to financial information. Companies need to determine which risks are material, identify appropriate metrics, establish internal controls and ensure that reported information can withstand scrutiny from investors, regulators and other stakeholders.
That process can be costly, particularly for companies with complex operations and fragmented supply chains. MTN Uganda said the transition of its extensive telecommunications infrastructure toward cleaner and more efficient energy requires significant investment. It also identified physical climate risks, changing regulation and value-chain management as continuing challenges. In 2025, 70 percent of its top suppliers by spending had pledged to the company’s net-zero commitment.
For smaller African businesses, the challenge can be even greater. Many lack dedicated sustainability teams, sophisticated data systems or the financial resources to undertake extensive reporting exercises. Yet these companies increasingly participate in supply chains serving larger corporations, export markets and financial institutions that may demand more information on emissions, labour practices, governance and climate exposure.
This creates a potential competitive divide. Companies that can produce credible sustainability information may find it easier to meet procurement requirements, demonstrate resilience to investors and participate in international value chains. Businesses without the systems to measure and disclose their exposure could face higher compliance costs or reduced access to some markets and sources of capital.
The issue is particularly relevant as African companies seek to finance expansion. Investors and lenders increasingly need information about risks that conventional financial statements may not fully capture. A manufacturing company exposed to water shortages, for example, may appear financially sound until the cost and availability of water begin to affect production. A telecommunications operator dependent on diesel generators may face rising operating costs and transition risks as energy systems change.
This is why the integration of climate and sustainability risks into enterprise risk management is becoming increasingly important. MTN Uganda says it has incorporated sustainability and climate-related risks into its enterprise risk-management framework, alongside a materiality assessment and Scope 3 accounting across 11 categories.
The economic case for such integration also extends into financial inclusion. MTN Uganda reported that the value of transactions through its Mobile Money platform rose to Shs195.5 trillion in 2025, while loans disbursed through the platform increased to Shs2.7 trillion. These services operate at the intersection of technology, finance and household economic activity, meaning that network reliability, affordability, customer protection and data governance can have consequences for millions of users and small businesses.
The company’s reporting also highlights an increasingly common attempt by African corporations to quantify broader economic and social value. A KPMG True Value Assessment cited by MTN estimated that the company generated Shs34.9 trillion in economic, social and environmental value above reported profits between 2022 and 2024. MTN itself cautions that this is not a conventional return-on-investment measure, but the calculation reflects the growing interest in understanding corporate value beyond the income statement.
Such measures are likely to remain contested. Assigning monetary values to social and environmental outcomes involves assumptions that are different from those used in conventional financial accounting. The figures can provide an additional perspective on corporate impact, but they should not be treated as equivalent to audited profits, cash flow or shareholder returns.
For African economies, the broader issue is whether sustainability can become embedded in productive investment rather than remaining a parallel reporting exercise. If companies invest in more efficient energy systems, resilient infrastructure, responsible supply chains and inclusive digital services because those measures strengthen the underlying business, sustainability becomes part of competitiveness rather than an additional layer of corporate activity.
There is also a public-policy dimension. MTN Uganda reported Shs1.6 trillion in taxes, duties and levies in 2025, demonstrating the fiscal importance of large companies operating in strategic sectors. When businesses face climate disruption or invest in resilience, the consequences can extend to government revenues and public infrastructure. Conversely, when companies reduce energy consumption, strengthen supply chains or expand productive access to digital services, some of the economic benefits can extend into the wider economy.
The transition will not be cost-free. Cleaner energy systems require capital, sustainability reporting requires data and assurance, and supply-chain transformation can increase short-term operating costs. African companies operating in markets where financing costs are already high will have to balance these investments against competing demands for expansion, employment and shareholder returns.
That makes governance particularly important. Boards and executives will increasingly need to determine which sustainability investments are financially material, which risks require immediate action and which targets can realistically be delivered. Sustainability ownership at board level does not mean every environmental or social initiative should automatically receive funding; it means the underlying risks and opportunities should be considered alongside other strategic decisions.
For Uganda and other African markets, the evolution of sustainability reporting could therefore have consequences well beyond disclosure. It can influence how companies allocate capital, how investors assess risk, how banks evaluate borrowers and how regulators understand emerging vulnerabilities across the economy.
The central question is no longer whether African companies should have sustainability departments. Those functions remain important for expertise, coordination and reporting. The more consequential question is whether sustainability considerations reach the boardroom, finance function, risk committee, procurement team and operational units where decisions about infrastructure, people, technology and capital are actually made.
MTN Uganda’s experience illustrates that transition. Its sustainability reporting now sits alongside financial and strategic performance, while climate risks have been incorporated into enterprise risk management and sustainability considerations into network investment, customer protection and operational planning. For a continent facing simultaneous pressures from climate change, infrastructure deficits, changing regulation and the need to mobilise private capital, that integration could become increasingly important to how African businesses preserve value and remain competitive.
