Nigeria’s sustainability-reporting transition moved into a clearer implementation phase in 2026. On 23 February 2026, the Financial Reporting Council of Nigeria unveiled an amended national Roadmap for adoption of IFRS Sustainability Disclosure Standards together with Sustainability Reporting Guideline 1 (SRG 1) 2026. The documents provide more detailed guidance on IFRS S1, IFRS S2, readiness assessment, reporting timelines and assurance expectations.
The voluntary window remains important
The amended Roadmap identifies 2024–2027 as the voluntary-adoption period for private-sector reporting entities. This is not a reason to wait. It is the period in which organisations are expected to build capacity, identify data gaps and prepare the governance and systems needed for mandatory reporting.
Mandatory adoption is phased
Under the amended Roadmap, public-interest entities move into mandatory adoption for accounting periods beginning on or after 1 January 2028, while SMEs are scheduled for accounting periods beginning on or after 1 January 2030, with early adoption encouraged. Government and government organisations also have a sustainability-reporting pathway beginning from 2028 under the applicable public-sector framework.
Readiness is more than writing a sustainability report
The FRC readiness process requires organisations to demonstrate that sustainability reporting has been embedded into governance and implementation planning. The Roadmap identifies early-stage documentation including board approval, a gap-analysis report and an implementation plan. The purpose is to show that the entity has considered people, processes, data, controls and reporting responsibility before publishing its first report.
IFRS S1 and IFRS S2 change the reporting conversation
IFRS S1 focuses on sustainability-related risks and opportunities that could reasonably be expected to affect an entity’s prospects. IFRS S2 focuses specifically on climate-related disclosures. The practical implication is that sustainability reporting must connect to governance, strategy, risk management, metrics and targets rather than operate as a stand-alone corporate-social-responsibility brochure.
Finance teams should be involved early
Many sustainability disclosures depend on information that sits outside the finance function, but the final reporting still requires controls, consistency, evidence and linkage to general-purpose financial reporting. Finance, risk, operations, legal, internal control, HR, procurement and board-level governance therefore need to work together.
Start with a gap analysis
Management should compare current reporting and data systems with the information required under IFRS S1 and IFRS S2. Typical gaps may include emissions data, climate-risk assessment, governance documentation, supplier information, scenario analysis, sustainability-related financial effects, internal controls and evidence trails.
Build controls before assurance becomes urgent
As sustainability information moves toward mandatory reporting and assurance, unsupported estimates and manually assembled spreadsheets become increasingly risky. Organisations should define data owners, review controls, calculation methodologies, source documentation and version control early enough for weaknesses to be corrected before reporting deadlines.
Practical actions for 2026
- Determine where the entity falls within the FRC adoption roadmap.
- Brief the board and senior management on the expected reporting pathway.
- Perform a structured IFRS S1/S2 gap analysis.
- Prepare an implementation plan with named responsibilities and timelines.
- Identify sustainability data sources and assess their reliability.
- Document controls over calculations, estimates and approvals.
- Consider assurance readiness as part of system design rather than as a final-year exercise.
