From CSR storytelling to regulated, decision-useful sustainability reporting

For many Nigerian companies, sustainability reporting has historically been treated as a communications exercise. Community photos, CSR updates, and general ESG statements often carried more weight than data-backed disclosures. That approach is no longer sufficient.

Under the Financial Reporting Council of Nigeria’s (FRCN) Sustainability Reporting Guideline 1 (SRG 1), and the broader IFRS Sustainability Disclosure Standards framework, sustainability disclosure is moving into a regulated reporting regime. As SRG 1 aligns with IFRS S1 and IFRS S2, organizations must now support sustainability claims with decision-useful information, robust governance, and auditable data.

Misleading or unsubstantiated ESG statements now create more than reputational risk. They can also expose organizations to regulatory, financial, and legal consequences.

Understanding the new framework

SRG 1 requires sustainability disclosures to be supported by material, decision-useful information rather than promotional storytelling. Relevant disclosures should be anchored in quantifiable data, verifiable methodologies, and clear corporate governance evidence.

IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) requires entities to disclose sustainability-related risks and opportunities that could reasonably affect cash flows, access to finance, or cost of capital over the short, medium, or long term.

IFRS S2 (Climate-related Disclosures) requires more granular reporting on climate-related risks and opportunities, including greenhouse gas emissions, transition plans, and scenario analysis where material.

Before publishing, entities should ensure that internal controls, data pathways, governance arrangements, and supporting documentation are sufficiently mature for external review and assurance.

The compliance timeline

The FRCN has adopted a phased implementation approach to give institutions time to strengthen their systems and internal controls.

Phase	Category of entities	Effective timeline
Phase 1 & 2	Early and voluntary adopters	Ongoing through 2027
Phase 3	All Public Interest Entities (PIEs) and listed entities	Mandatory for periods beginning on or after 1 January 2028
Phase 4	Government organisations and public sector entities	Mandatory by 2028
Phase 5	Qualified small and medium-sized enterprises (SMEs)	Mandatory by 1 January 2030

What SRG 1 means for executive leadership

• Board accountability intensifies: Directors and audit committees can no longer treat ESG as a communications issue. Boards should establish clear escalation pathways, monitor sustainability-focused KPIs, and integrate climate risk into the enterprise risk management framework.
• Data and controls are now mission-critical: High-integrity disclosures require traceable data flows. Organizations should document methodologies for Scope 1, Scope 2, and where relevant Scope 3 emissions, together with the assumptions used in any carbon pricing or scenario analysis.
• Audit readiness is non-negotiable: Sustainability statements are increasingly expected to sit alongside general-purpose financial reporting. Unverified narratives and unsupported claims will attract scrutiny and can undermine investor confidence.

Common red flags in ESG data

1. Qualitative dependency

Exposure: Relying on open-ended narratives without underlying quantification, standardized calculation methodologies, or a clear evidence trail.

Immediate action: Start with a rapid data-inventory exercise. Select one high-profile sustainability claim, trace its data lineage back to the source, identify gaps, assign ownership, and document the calculation logic needed to substantiate it.

2. Unreconciled Scope 2 accounting

Exposure: Reporting only market-based Scope 2 figures without reconciling them to location-based emissions and the realities of local grid intensity.

Immediate action: Perform a dual-track reconciliation for one facility or region. Calculate both market-based and location-based Scope 2 metrics, explain the variance, and document the basis for management’s reporting approach.

3. Arbitrary carbon assumptions

Exposure: Applying internal carbon prices or climate assumptions without formal governance, scenario analysis, or documented approval.

Immediate action: Convene Finance, Risk, and Operations to test at least two carbon-price scenarios and log the resulting financial sensitivities.

4. The communications silo

Exposure: Keeping sustainability information inside public relations or marketing teams, which often leads to reports dominated by generic imagery, awards, or promotional language.

Immediate action: Embed a core sustainability KPI into monthly management packs as a financial intensity metric, such as emissions per unit of revenue or production.

Practical steps to build readiness

• Conduct a targeted gap assessment by benchmarking current reporting practices against IFRS S1, IFRS S2, and SRG 1, with particular focus on data blind spots in high-materiality business areas.
• Codify emission boundaries by documenting organizational boundaries and calculation methodologies for Scope 1, Scope 2, and material Scope 3 reporting.
• Embed climate risk into capital allocation through formal scenario analysis and explicit carbon pricing assumptions in financial planning and budgeting.
• Institutionalize data governance by applying the same internal controls and quality assurance protocols used for financial data.
• Design for external assurance by centralizing source data, emission factors, assumptions, and governance minutes so that auditors and assurance providers can test disclosures efficiently.
• Mobilize executive leadership through concise, finance-focused briefings for the Board and Audit Committee, linking reporting choices to cost of capital, regulatory standing, and market valuation.

Final thought

SRG 1 marks an important shift: sustainability disclosure is evolving from optional corporate storytelling into regulated financial reporting. For senior leaders, the challenge is no longer whether to disclose, but how to build the systems needed to make disclosures accurate, auditable, and aligned with business strategy.

Organisations that invest early in data governance, internal controls, and assurance readiness will be better positioned to strengthen investor confidence and improve market trust.
