The Basics of Sustainability Reporting: Nigeria Context

 

Introduction

In today’s global business environment, sustainability reporting is no longer a nice-to-have, it is becoming a fundamental expectation. In Nigeria, this shift is accelerating rapidly. While many large companies have voluntarily embraced sustainability disclosures, the Nigerian Corporate Sustainability Index (NCSI)’s five-year back-test, as reported by sustainablestories.africa, shows that standalone sustainability reports among reviewed Nigerian companies stand at around 33%, with broader ESG disclosure rates on the Nigerian Exchange declining from 55% in 2022 to 42% in 2024. Yet, the regulatory landscape is tightening: Nigeria became the first African country to commit to adopting the International Sustainability Standards Board (ISSB)’s International Financial Reporting Standards (IFRS) S1 & S2 standards, with mandatory reporting for Public Interest Entities (PIEs) scheduled from January 2028, and January 2030 for other companies.

Sustainability reporting is the practice of measuring, managing, and publicly disclosing an organisation’s Environmental, Social, and Governance (ESG) impacts and performance alongside traditional financial results. It goes beyond profits to show how a company affects its community, environment, and stakeholders, and how it manages risks and opportunities for long-term value creation.

For Nigerian businesses, sustainability reporting is particularly relevant. The country faces significant climate vulnerabilities — from oil spills and gas flaring in the Niger Delta to deforestation and agricultural disruptions. At the same time, sustainability reporting offers huge opportunities through the Energy Transition Plan targeting net-zero emissions by 2060, green finance, foreign direct investment, and alignment with global standards. Investors, regulators, customers, and communities increasingly demand transparency. The Nigeria Energy Transition Plan (ETP) reports that Banks following the Nigerian Sustainable Banking Principles (NSBP), listed companies on the NGX, and companies seeking international capital all benefit from credible sustainability reporting.

This article provides the basics of sustainability reporting tailored to the Nigerian context. It synthesizes what it entails, why it matters locally, key frameworks (including ISSB), practical steps to prepare a report, common challenges, and future trends. Whether you run a listed company, SME, or public interest entity, these basics will help you start or strengthen your sustainability journey.

The trend reflects growth in sustainability reporting among listed companies in Nigeria between 2015 and 2025 as estimated percentage of top listed companies (NGX/NSE) with sustainability/ESG disclosure. The trend also shows key regulatory milestones which are:

• 2015 – NGX Sustainability Disclosure Guideline first issued; FRC Nigeria begins ESG frameworks
• 2018 – SEC approves NSE Sustainability Disclosure Guidelines for all listed companies
• 2019 – Mandatory for Premium Board; NCCG released by FRC; NGX SDGs updated
• 2021 – SEC Guidelines on Sustainable Financial Principles mandates ESG reporting for regulated entities
• 2023 – NGX RegCo confirms ~50% full adoption; Nigeria targets carbon neutrality by 2060.

What is Sustainability Reporting?

Sustainability reporting is the process by which organisations publicly disclose their ESG impacts, risks, opportunities, and performance. It provides a transparent account of how a company’s operations affect people, the planet, and long-term value creation, going far beyond traditional financial results.

In Nigeria, the Financial Reporting Council of Nigeria (FRCN) has adopted the International Sustainability Standards Board (ISSB) standards — specifically IFRS S1 (General Sustainability-related Disclosures) and IFRS S2 (Climate-related Disclosures) — as the national baseline. This makes sustainability reporting a structured, decision-useful practice aligned with global expectations while addressing local realities.

Understanding the ESG Pillars

Sustainability reporting is built on three interconnected pillars, commonly known as ESG:

• Environmental: Covers a company’s impact on the natural environment. In Nigeria, this includes greenhouse gas emissions, gas flaring reduction, oil spill management, waste and effluent handling, water usage, deforestation, and biodiversity protection — particularly critical in the Niger Delta and agricultural regions.
• Social: Focuses on relationships with people and communities. Key areas include local content development, gender equality and inclusion, labour practices, community engagement, human rights, health and safety, and talent development.
• Governance: Addresses leadership, ethics, and internal controls. This includes board diversity and independence, anti-corruption measures, transparency in reporting, risk management, and compliance with laws such as those enforced by the EFCC and SEC.

How Sustainability Reporting Differs from Traditional Financial Reporting

While financial reporting focuses on historical financial performance (revenue, profit, assets, and liabilities) for investors and regulators, sustainability reporting emphasises forward-looking information on non-financial risks and opportunities. According to PwC, sustainability reporting addresses broader stakeholder needs — including communities, employees, customers, and civil society — and often covers qualitative narratives alongside quantitative metrics.

In the Nigerian context, sustainability reporting helps businesses manage unique challenges like climate vulnerability, regulatory compliance (e.g., CBN Sustainable Banking Principles and NGX guidelines), and the expectations of international investors seeking credible ESG data.

Core Purposes in Nigeria:

• Enhance transparency and build stakeholder trust.
• Improve risk management and long-term resilience.
• Drive accountability and better decision-making.
• Unlock access to green finance and foreign investment.
• Support national goals such as the Energy Transition Plan (net-zero by 2060).

By understanding these foundations, Nigerian organisations can move from basic compliance to using sustainability reporting as a strategic tool for competitiveness and sustainable growth.

Why Sustainability Reporting Matters in Nigeria

Sustainability reporting is rapidly moving from a voluntary practice to a strategic necessity for Nigerian businesses. With the Financial Reporting Council of Nigeria (FRCN) adopting the ISSB’s IFRS S1 and IFRS S2 standards, mandatory reporting for Public Interest Entities (PIEs) begins from January 2028, while SMEs follow from 2030. This regulatory shift aligns Nigeria with global expectations and signals that strong ESG performance and transparent disclosure are now critical for competitiveness.

Benefits to Business

Companies that report effectively on sustainability gain several advantages:

• Access to Capital and Investment: International and local investors increasingly use ESG data to make decisions. Strong sustainability reporting improves access to green finance, sustainability-linked loans, foreign direct investment, and lower cost of capital. Weak reporting, on the other hand, limits funding opportunities in a market where global investors prioritise ESG factors. While speaking in Abuja at the launch of the Nigerian Corporate Sustainability Report by Norrenberger Research, the analytical arm of Norrenberger Group, Dr Emomotimi Agama, the Director-General of Securities and Exchange Commission said, “Nigerian companies that wish to access the vast pool of patient, long-term capital must understand one unambiguous reality: the price of entry is disclosure. Credible, consistent, comparable, and verifiable disclosure.”
• Risk Management and Resilience: According to Nigeria Energy Transition Plan (ETP), Nigeria faces climate risks (flooding, droughts, oil spills) and social challenges. Reporting helps companies identify, manage, and mitigate these risks while uncovering opportunities in the Energy Transition Plan, which targets net-zero emissions by 2060.
• Reputation, Talent, and Stakeholder Trust: Transparent reporting builds trust with customers, communities (especially in the Niger Delta), employees, and regulators. It enhances brand reputation and helps attract and retain talent in a competitive market.
• Regulatory Compliance and Market Access: Adherence to NGX Sustainability Disclosure Guidelines, CBN Nigerian Sustainable Banking Principles, and SEC requirements reduces compliance risks and supports participation in sustainable finance markets.

Broader National and Economic Impact

Sustainability reporting supports Nigeria’s development goals by promoting accountability, driving innovation in green sectors, and helping close the SDG financing gap. It positions Nigerian businesses to compete globally and contributes to economic resilience, job creation (projected through the Energy Transition Plan), and environmental protection.

For SMEs: Although challenges exist, early adoption can provide a competitive edge, improve access to finance, and prepare businesses for future mandates.

In summary, sustainability reporting is no longer just about compliance — it is a strategic tool for long-term value creation, risk mitigation, and sustainable growth in Nigeria’s evolving economy. Businesses that act now will be better positioned to thrive in a sustainability-driven future.

Key Elements and Components of a Sustainability Report

A well-prepared sustainability report is more than a collection of data. It is a clear, credible document that shows how an organisation manages its most important ESG risks and opportunities. In the Nigerian context, the report should align with the FRCN’s Sustainability Reporting Guideline (SRG1) and the adopted ISSB standards (IFRS S1 and IFRS S2).

1. Materiality Assessment

The foundation of any good sustainability report is materiality assessment. This process identifies the ESG issues that are most significant to the organisation and its stakeholders.

In Nigeria, companies are encouraged to apply double materiality — considering both:

• How sustainability issues affect the company’s financial performance (financial materiality), and
• How the company’s operations impact the environment and society (impact materiality).

For example, an oil and gas company in the Niger Delta needs to prioritise oil spill prevention and community relations, while a manufacturing firm may focus on energy efficiency and waste management.

2. Key Content Areas (Core Elements)

Under IFRS S1 and S2, reports typically cover four main content elements:

• Governance: How the board and management oversee sustainability-related risks and opportunities.
• Strategy: The organisation’s approach to managing material sustainability issues, including business model, value chain, and alignment with Nigeria’s Energy Transition Plan.
• Risk Management: Processes for identifying, assessing, and managing ESG risks (e.g., climate-related physical and transition risks).
• Metrics and Targets: Quantitative and qualitative performance data, including baselines, progress, and time-bound targets (e.g., reduction in GHG emissions or gender diversity goals).

3. Common Topics Relevant to Nigerian Businesses

• Environmental: GHG emissions and gas flaring, energy consumption, water management, waste, biodiversity.
• Social: Community engagement, local content, gender equality, labour practices, human rights.
• Governance: Anti-corruption measures, board diversity, ethical conduct, transparency, and risk oversight.

Data Reliability and Assurance: Use accurate, verifiable data. As Nigeria moves toward mandatory reporting, external assurance will become increasingly important for credibility.

By focusing on these key elements, Nigerian organisations can produce reports that meet regulatory expectations, build stakeholder trust, and support better business decisions.

Major Frameworks and Standards Used in Nigeria

Nigeria is aligning its sustainability reporting with global best practices while addressing local needs. According to Financial Reporting Council of Nigeria (FRCN), the country has officially adopted the International Sustainability Standards Board (ISSB) standards — IFRS S1 (General Sustainability-related Disclosures) and IFRS S2 (Climate-related Disclosures) — as the national baseline for sustainability reporting.

Key Frameworks Relevant to Nigeria

1. International Sustainability Standards Board (ISSB) / International Financial Reporting Standards (IFRS) S1 & S2 These form the primary global baseline adopted by Nigeria. IFRS S1 requires disclosure of material sustainability-related risks and opportunities, while IFRS S2 focuses on climate-related issues. They emphasise financial materiality, governance, strategy, risk management, and metrics and targets. Mandatory application for Public Interest Entities (PIEs) begins for accounting periods starting on January 1, 2028. Mandatory application for other companies begins for accounting periods starting on January 1, 2030.
2. NGX Sustainability Disclosure Guidelines Issued by the Nigerian Exchange Group, these guidelines encourage listed companies to disclose ESG performance. They remain relevant alongside ISSB standards.
3. Global Reporting Initiative (GRI) Standards Widely used voluntarily in Nigeria for broad impact reporting. GRI is stakeholder-focused and covers a wide range of topics, making it useful for companies that want to communicate broader societal impacts.
4. Other Important Frameworks
   • TCFD (Task Force on Climate-related Financial Disclosures): Now integrated into IFRS S2.
   • CBN Nigerian Sustainable Banking Principles (NSBP): Mandatory for banks and provides sector-specific guidance.
   • SEC Sustainable Finance Principles: Support capital market participants.
   • Sustainability Accounting Standards Board (SASB) / ISSB Industry-based Standards: Helpful for industry-specific metrics.

Framework	Primary Focus	Applicability	Complexity	Status in Nigeria	Best For
ISSB (IFRS S1 & S2)	Financial materiality + Climate	PIEs, other companies	Medium – High	Mandatory for PIEs from 2028   Mandatory for other companies from 2030	Listed companies, PIEs, Other companies
NGX Guidelines	ESG disclosure	Listed companies	Medium	Recommended / Voluntary	Listed entities
GRI Standards	Impact materiality	All organisations	Medium	Voluntary	Broad stakeholder reporting
Central Bank of Nigeria Nigerian Sustainable Banking Principles (CBN NSBP)	Banking sector sustainability	Banks & financial institutions	Medium	Mandatory for banks	Financial sector
TCFD	Climate-related risks	All	Medium	Integrated into IFRS S2	Climate focus

 

Practical Advice for Nigerian Businesses

• Start with ISSB/IFRS S1 & S2 if you are a Public Interest Entity or listed company, as this will become mandatory.
• Other companies should begin voluntarily reporting to build capacity ahead of mandatory compliance from 2030.
• Many companies use a combination: ISSB for core compliance + GRI for additional impact storytelling.
• Always conduct a gap analysis against the chosen framework and align with the Financial Reporting Council of Nigeria (FRCN) Sustainability Reporting Guideline (SRG1).

FRCN advises companies to start early as early preparation will ease the transition to mandatory reporting and unlock strategic benefits.

Step-by-Step Guide to Preparing a Sustainability Report in Nigeria

Preparing a sustainability report may seem daunting, but following a structured approach makes the process manageable. Here is a practical, step-by-step guide tailored for Nigerian businesses.

Step 1: Secure Leadership Buy-in and Define Scope

Gain commitment from the Board and senior management. Define the report’s objectives, reporting period, and boundaries (which operations, subsidiaries, and value chain segments to include). Align the report with your company’s overall strategy and Nigeria’s Energy Transition Plan.

Step 2: Conduct a Materiality Assessment

Identify the most relevant ESG issues for your business and stakeholders. Engage internal and external stakeholders (employees, communities, investors, regulators) through surveys, interviews, or workshops.

In the Nigerian context, consider local priorities such as gas flaring, community development in the Niger Delta, gender inclusion, and climate resilience. Document the process clearly — this is a core requirement under IFRS S1.

Step 3: Collect and Measure Data

Gather reliable qualitative and quantitative data on the material topics. Common metrics include GHG emissions (Scope 1, 2, and where possible Scope 3), energy consumption, water usage, waste generated, gender diversity ratios, community investment, and anti-corruption incidents.

Nigerian Challenges & Solutions:

• Data gaps are common — start with available internal records and gradually improve systems.
• Leverage industry benchmarks from NGX, CBN, or sector associations.

Step 4: Select Framework and Draft the Report

Choose the appropriate framework (primarily ISSB/IFRS S1 & S2 for PIEs and other companies). Structure the report around the four pillars: Governance, Strategy, Risk Management, and Metrics & Targets. Write the report keeping the language simple and professional.

Step 5: Review, Verify, and Assure the Report

Conduct an internal review for accuracy and completeness. For higher credibility, especially as mandatory reporting approaches, seek external assurance from qualified professionals. Even limited assurance adds significant value.

Step 6: Publish, Communicate, and Improve

Publish the report on your company website and file with the NGX (for listed companies) or FRCN for other companies as required. Communicate key findings through press releases, stakeholder meetings, and social media. Most importantly, use the insights from the report to drive actual performance improvements. Sustainability reporting is not a one-time event — it is a continuous cycle of measure, report, and improve.

Common Challenges and Best Practices for Nigerian Businesses

While the benefits of sustainability reporting are clear, many Nigerian organisations face practical hurdles in implementation. Recognising these challenges and adopting proven best practices can make the process smoother and more effective.

Common Challenges

Nigerian businesses encounter several obstacles when preparing sustainability reports:

• Data Collection and Quality Issues: Many companies lack robust systems to track ESG data, especially Scope 3 emissions, community impact metrics, and supply chain information. Appropriate guidance can alleviate this challenge.
• Limited Internal Capacity and Skills: Shortage of trained personnel who understand ESG concepts, ISSB standards, and data analysis. Awareness remains low outside large listed companies and multinational subsidiaries.
• Cost Implications: Initial investments in systems, training, and possible external assurance can be burdensome, especially in undertaking a full compliance immediately.
• Regulatory Uncertainty and Enforcement Gaps: Although the FRCN has set a clear 2028 mandatory timeline for PIEs, some businesses still perceive sustainability reporting as “voluntary for now,” leading to delayed action.
• Risk of Greenwashing: Pressure to present a positive image can lead to exaggerated claims or selective reporting, which damages credibility when discovered.

Best Practices for Success

To overcome these challenges, Nigerian organisations should consider the following practical approaches:

1. Start Small and Scale Gradually: Phase out sustainability reporting beginning with most material issues rather than attempting full compliance immediately.
2. Build Internal Capacity: Invest in staff training through relevant workshops. Create a cross-functional sustainability team and appoint a focal person (Chief Sustainability Officer where possible).
3. Leverage Technology and Partnerships: Adopt relevant and affordable digital tools in phases. Partner with consultants, industry associations, or development organisations for technical support.
4. Ensure Transparency and Honesty: Clearly disclose data limitations, challenges faced, and improvement plans. These build trust more effectively than perfect-looking but unrealistic reports.
5. Seek External Support and Assurance: Engage qualified professionals for materiality assessments and limited assurance.
6. Integrate Sustainability into Core Business: Embed ESG considerations into strategy, budgeting, and performance management rather than treating reporting as a standalone compliance exercise.

By addressing challenges proactively and following these best practices, Nigerian businesses can transform sustainability reporting from a burden into a powerful driver of improvement, credibility, and long-term competitiveness.

The Future of Sustainability Reporting in Nigeria

The future of sustainability reporting in Nigeria is promising and transformative. The country is positioned to become a leader in sustainability disclosure across Africa following its early adoption of ISSB standards.

Key Trends

• Mandatory Reporting Expansion: Public Interest Entities (PIEs) and listed companies will begin mandatory reporting under IFRS S1 and IFRS S2 from January 2028. This requirement is expected to extend to other companies by 2030, making sustainability reporting the norm rather than the exception for Nigerian businesses.
• Greater Integration and Assurance: Sustainability reports will increasingly integrate with financial statements, creating a single, cohesive report on value creation. External assurance will move from voluntary to expected, and eventually mandatory for larger entities, significantly improving data credibility.
• Digital Reporting and Technology: The adoption of digital formats such as XBRL (eXtensible Business Reporting Language) will make reports more accessible, comparable, and machine-readable for investors and regulators.
• Rising Focus on Climate and Nature: With Nigeria’s Energy Transition Plan targeting net-zero by 2060, companies will face stronger expectations to disclose climate transition plans, biodiversity impacts, and just transition strategies.

Opportunities for Nigerian Businesses

Early movers who invest in sustainability reporting today will gain competitive advantages through better access to green finance, enhanced investor confidence, stronger stakeholder relationships, and improved operational efficiency. The growth of sustainable finance products, carbon markets, and ESG-focused investment funds presents significant economic opportunities.

For Nigeria as a whole, widespread adoption of high-quality sustainability reporting will support the attraction of foreign direct investment, accelerate the green economy, and help achieve national development and climate goals.

Businesses that start preparing now — building systems, developing skills, and embedding sustainability into strategy — will be best positioned to thrive in the coming era of mandatory, transparent, and integrated reporting.

Conclusion

Sustainability reporting is no longer optional for forward-thinking Nigerian businesses. It has become a vital tool for transparency, risk management, regulatory compliance, and long-term value creation.
