MTN Nigeria has strengthened its commitment to corporate transparency and ethical business practices after publishing its 2025 sustainability report in line with global disclosure standards set by the International Financial Reporting Standards (IFRS).
The telecom operator said the report, which was independently assured by professional services firm Ernst & Young, represents its seventh consecutive annual sustainability publication and its third year as an early adopter of the IFRS S1 and S2 frameworks ahead of their mandatory implementation.
The IFRS S1 and S2 standards, developed by the International Sustainability Standards Board (ISSB), provide a global framework for companies to disclose sustainability-related financial information and climate risks to investors.
MTN Nigeria Chief Executive Officer Dr Karl Toriola said strong governance and ethical conduct remained central to the company’s sustainability strategy.
“Strong governance and ethical conduct are foundational to our sustainability strategy. We reinforced compliance through our Conduct Passport Framework and robust internal controls,” Toriola said.

He added that MTN Nigeria became the first telecommunications company in the country to publicly present a sustainability report on the Nigerian Exchange Group platform in May 2025, describing it as a key milestone in the company’s push for greater accountability and transparency.
The report highlighted the company’s approach to identifying and managing environmental, social and governance (ESG) risks while improving access to sustainability data for investors and regulators.
MTN Nigeria also disclosed that it had adopted a digital reporting format known as XBRL, allowing sustainability and governance information to be accessed and analysed more efficiently by investors, regulators and ESG rating agencies through automated systems.
Under the IFRS S2 climate-related disclosure framework, the company outlined potential risks facing its operations, including flooding, extreme heat, regulatory changes and possible future carbon-related taxes or charges.
The company said these risks were assessed through a climate scenario analysis conducted in 2024, aimed at understanding how different climate conditions could affect its long-term business performance.
MTN Nigeria also reported progress in global climate-related assessments, receiving a “B-” rating from the Carbon Disclosure Project (CDP) for climate change and a “C” rating for water security.
The telecom firm said it carried out additional assessments to examine how sustainability challenges affect both its operations and wider society, while measuring its economic and environmental impact.
The latest report comes as companies across Africa face increasing pressure from investors and regulators to improve sustainability reporting and demonstrate stronger corporate responsibility.
MTN Nigeria said its continued alignment with international reporting standards reflects its broader objective of building trust among stakeholders and ensuring responsible growth in the telecommunications sector.
