Washing and Hushing

Businesses keep meticulous records of revenue, assets, liabilities, and shareholder returns. In the corporate world, financial reporting has long been a legal obligation. But there is non-financial reporting, which is arguably just as important in today’s age of climate change. On this, many businesses still struggle with accurate and transparent disclosure of their greenhouse gas emissions.

This struggle is remarkable considering the scale of corporate influence on the planet. The largest corporations collectively represent a massive share of global economic activity and environmental impact, with studies showing that they account for roughly 30 percent of global carbon dioxide emissions. Yet despite the scale of their impact, emissions disclosure remains inconsistent with transparency and accountability gaps every now and then. Many companies speak confidently about sustainability ambitions while revealing little about the carbon footprint of their operations. For climate responsibility and accountability, this is a serious data gap.

Disclosure: The Data Behind Climate Commitments

The transparency of carbon emissions begins with measurement. Emissions reporting generally follows the internationally recognized framework of the Greenhouse Gas Protocol, which categorizes emissions into three levels: Scope 1 – direct emissions from company operations; Scope 2 – indirect emissions from purchased energy; and Scope 3 – emissions across the value chain, including suppliers and further down the product life cycle. These categories are not arbitrary classifications. They are designed to reveal the full climate footprint of corporate activity from factory smokestacks to electricity consumption to supply chains spanning multiple continents. The significance of this reporting goes far beyond environmental advocacy. Emissions data is now treated as financially material information, meaning investors increasingly view it as essential to evaluating corporate risk. Investment decisions are driven by a company’s business model – whether or not it depends heavily on fossil fuels, carbon-intensive infrastructure, or fragile supply chains vulnerable to climate regulation. Carbon disclosure therefore, functions as a risk disclosure mechanism for the global economy. This is why environmental disclosure platforms such as the Carbon Disclosure Project (CDP) have become central to corporate transparency. In 2023 alone, over 23,000 companies representing more than $67 trillion in market capitalization reported environmental data through CDP, illustrating the scale of the growing transparency movement. 

Corporate disclosure statistics often appear encouraging at first glance. Thousands of companies now publish environmental information annually. But a deeper look reveals a troubling reality: disclosure is expanding faster than accuracy and accountability. Research examining emissions reporting across hundreds of companies found that one in five firms reported different greenhouse-gas figures in their sustainability reports compared to the data they submitted through disclosure platforms. In some cases, the discrepancies exceeded 50 percent. This is not a minor accounting error, when companies publish inconsistent carbon data it undermines trust in the entire sustainability reporting system. Even more concerning is the issue of incomplete disclosures. Globally, only about 65 percent of large and mid-sized companies disclose emissions data, leaving a significant portion of corporate carbon footprints unreported. The implication is clear: the global climate data landscape still contains large blind spots and these blind spots make it difficult for regulators, investors, and the public to assess whether corporate climate commitments are genuine or merely rhetorical or simply greenwashing. 

Yet disclosure does not always equate to transparency. While more companies are reporting emissions, the quality, completeness, and consistency of the data remain deeply uneven. In Nigeria, the transparency gap is often more basic. Many companies do not publish comprehensive emissions data at all. Corporate sustainability reports frequently highlight renewable energy investments, environmental community programmes, or tree-planting campaigns. Yet the total carbon footprint of corporate operations including energy consumption, industrial processes, and supply-chain emissions is rarely disclosed in a comprehensive and comparable format. This selective disclosure creates a governance blind spot. Policymakers attempting to implement climate regulations may lack the very data needed to measure compliance.

Data Blindspot in Nigeria’s Climate Governance

Nigeria’s Climate Change Act and Energy Transition Plan signal strong national ambition to address climate change through carbon budgets, energy transition policies, and international climate commitments. However, a major structural weakness threatens the effectiveness of these efforts: the lack of mandatory corporate emissions disclosure. Climate governance depends on accurate data. Without companies reporting their greenhouse-gas emissions, Nigeria cannot reliably measure progress on carbon budgets, monitor energy transition goals, or track reductions required under the Paris Agreement. Many industries responsible for large emissions, such as oil and gas, manufacturing, transportation, and power, still operate within largely voluntary reporting frameworks, leaving policymakers with incomplete information. This gap also affects financial markets and development finance. While institutions like the Nigerian Exchange Limited, Securities and Exchange Commission (SEC), and Central Bank of Nigeria (CBN) encourage sustainability reporting, most disclosure rules are not strictly enforced. As a result, companies can publish sustainability narratives without providing detailed emissions data, limiting investors’ ability to assess climate risks. The absence of reliable corporate emissions data also constrains Nigeria’s ability to attract climate finance, since global funding mechanisms increasingly require transparent, verifiable emissions accounting. Ultimately, Nigeria’s climate ambitions risk being weakened by a data deficit. Without mandatory corporate emissions disclosure, carbon budgets cannot be monitored, energy transition progress cannot be measured, and national climate commitments cannot be credibly verified. As climate governance evolves globally, Nigeria may eventually need to shift from voluntary to mandatory reporting, making corporate carbon disclosure a central pillar of climate accountability. The absence of emissions reporting becomes particularly visible when examining specific sectors of Nigeria’s economy. Investigations conducted through the SOStainability’s Sustainability Visibility Scans (SVS) published on this page have repeatedly exposed the disconnect between climate policy ambitions and corporate accountability.

For example,  the SVS of the aviation industry found that Nigerian airlines are doing virtually nothing on climate governance, despite aviation being one of the fastest-growing sources of global emissions. Detailed emissions reporting is largely absent from corporate disclosures within the sector. Similarly, our SVS of Nigeria’s construction industry revealed that climate considerations remain largely absent from infrastructure planning, even though cement production and building materials contribute significantly to global emissions. The real estate sector presents another example. Nigeria’s urban expansion has produced a wave of high-rise residential and commercial developments, yet energy efficiency standards and climate performance benchmarks remain largely unaddressed within the industry. These scans highlight a broader pattern: climate discussions often occur at the policy level through government commitments and international agreements. But within corporate governance structures, transparent disclosure remains limited. Without disclosure, it becomes difficult to determine whether industries are aligning with Nigeria’s climate goals or quietly expanding the country’s carbon footprint.

Why Corporate Compliance Remains Low

The common explanation for low disclosure is that emissions reporting is complex or technically difficult. While this claim cannot be dismissed, it is far from the whole story. The deeper reasons are institutional, strategic, and sometimes political. First, many companies lack internal carbon accounting systems. Measuring emissions requires collecting data across operations, energy consumption, transportation networks, and supply chains. In organizations that have historically prioritized financial reporting alone, building this infrastructure requires investment and expertise. Second, emissions data can expose uncomfortable truths. High carbon intensity may reveal operational inefficiencies, outdated technologies, or environmental risks that investors might interpret negatively. For some companies, non-disclosure becomes a form of reputational risk management. Third, voluntary reporting frameworks create incentives for selective transparency. Companies may publish sustainability narratives highlighting renewable energy investments or community projects while quietly omitting comprehensive emissions figures- in such cases, disclosure becomes storytelling rather than an accountability measure. Finally, there is a structural issue within the global governance system itself: enforcement remains weak. Without strong regulatory oversight, companies face limited consequences for failing to publish complete emissions data. The result is a reporting ecosystem where compliance is superficial but accountabilityremains uneven.

Why Emissions Data Must Be Public and Accessible

Transparency is not achieved simply by producing reports. For carbon disclosure to serve its accountability function, emissions data must be publicly accessible, easily verifiable, and regularly updated. Too often, corporate emissions information is hidden deep within lengthy sustainability reports published once a year in complex technical language. These documents are rarely read by the public and are often difficult for analysts to compare across companies. Publishing emissions data directly on corporate websites alongside climate targets, reduction strategies, and progress metrics can transform disclosure into a genuinely transparent practice. When emissions data becomes visible, several powerful accountability mechanisms emerge simultaneously: Investors can compare corporate climate performance across sectors: journalists and researchers can scrutinize inconsistencies;  civil society organizations can track progress toward climate goals; and regulators can verify whether companies are complying with reporting standards. Transparency, in this sense, becomes a form of public oversight.

If emissions disclosure is the foundation of corporate climate accountability, regulators must serve as its guardians. Environmental agencies, financial regulators, and stock exchanges must work together to ensure that climate reporting is not treated as optional corporate storytelling. The responsibility of regulators extends beyond issuing reporting guidelines. It includes monitoring disclosures, verifying data accuracy, and imposing consequences when companies fail to comply. Without enforcement, the disclosure system risks becoming symbolic rather than substantive. Nigeria has adopted climate legislation, developed an energy transition strategy, and increasingly engaged financial regulators in sustainability governance. These developments suggest that Nigeria is positioning as a climate-aware emerging economy. But climate governance ultimately depends on data. Without corporate emissions disclosure, carbon budgets cannot be monitored. Energy transition milestones cannot be measured. Climate finance cannot be verified. And national climate commitments cannot be credibly assessed.

NCIS London: Opportunity to Showcase Climate and ESG Credentials to a Global Audience

The world’s creme de la creme in global climate diplomacy, climate finance, and the business and investment community will gather in London for the Nigeria Climate Investment Summit (NCIS) in June. Designed as a key event of this year’s London Climate Action Week, the Summit will deepen engagement on Nigeria’s recent climate policy strides, transition finance, and structured capital mobilization for bankable projects by public and private sector entities.

Hosted by SOStainability in partnership with GLOBE Legislators, the NCIS will convene senior Nigerian officials, including the leadership and members of the National Assembly, Heads of Ministries, Departments and Agencies, key regulators, corporate organisations, and other pertinent actors alongside members of the UK investment community, Development Finance Institutions, regulators, institutional investors, businesses, and diaspora capital networks. The Summit offers curated opportunities for corporate positioning within global climate policy and diplomacy architecture, institutional profiling, and targeted visibility for companies and other organisations. Specifically, it presents partners and participating institutions the opportunity to network and highlight their sustainability and ESG achievements, climate alignment, and transition finance positioning in a format tailored to international audiences.

Billed to hold at a premium and historic location in the centre of London’s finance and business precinct, NCIS will feature plenary, technical, and panel sessions as well as the formal public presentation of SOStainability’s Policy Paper on the Climate Governance and ESG Positioning of Companies in Nigeria. This policy paper focuses on Development Finance Institutions (DFIs) and the financial services sector of the country. For context, the London Climate Action Week has evolved into the leading and most consequential global climate platform, working with the COP Presidencies and the UNFCCC to build momentum and shape diplomacy and shape investment ahead of COP31 in Antalya.

Trends and Threads

Nigeria: Accountability and Development Partnerships  

International development partnerships play important roles in development practice. Governments mobilise loans and grants from multilateral lenders, global institutions, and bilateral partners to fund projects that promise to transform lives. In Nigeria, these partnerships support major interventions in water supply, agriculture, climate adaptation, energy access, and poverty reduction. They are central to achieving the global development agenda embodied in Sustainable Development Goal 17, which calls for strong partnerships that mobilise resources and expertise for sustainable development.

Yet beneath the language of cooperation and financing commitments lies a salient but troubling question: when development cash enters Nigeria’s public systems, who actually tracks where it goes and whether it achieves the outcomes it was designed to deliver? Recent revelations surrounding missing funds in a World Bank–supported water project and the stalled release of billions of naira in agricultural intervention financing are cases that amplify these questions. They reveal systemic weaknesses in monitoring, transparency, and accountability within Nigeria’s development finance architecture. 

Following the Money: The $32 million water project controversy

In its FY2024 Sanctions System Annual Report, the World Bank disclosed that it had uncovered financial irregularities linked to a water project in Nigeria. A forensic financial review revealed that $32 million associated with the project could not be properly accounted for. The discovery triggered sanctions against a Nigerian engineering company and its managing director after investigators determined that fraudulent misrepresentation had occurred during the procurement and implementation process. The Bank also instructed Nigeria’s Central Bank to reimburse $22 million, while $6 million were identified as unspent funds remaining in a project account. The irregularities were detected through a forensic investigation conducted long after project implementation had begun. This shows that routine monitoring systems that should have tracked project finances in real time failed to identify the problem before millions of dollars had already moved through the system. This raises a critical question about the architecture of oversight in donor‑funded projects. If a discrepancy of this magnitude can persist until a forensic investigation exposes it, what does that say about the reliability of existing monitoring frameworks? Development partners often emphasise strict procurement guidelines and fiduciary safeguards, yet this case suggests that those safeguards may not be enough, especially when projects transition from donor domains to implementation.

Agricultural Funds That Never Reached Farmers

While the water sector case exposes weaknesses in financial accountability, a controversy within Nigeria’s agricultural sector reveals another form of governance failure: development finance that becomes immobilised within government systems before it can reach intended beneficiaries. Nigeria’s House of Representatives Committee on Agricultural Production and Services launched an investigation into the non‑release of ₦174.26 billion in agricultural intervention funds secured from international development partners. These funds were intended to support programmes designed to strengthen food production and support smallholder farmers. One component of the funding originated from a $134 million loan facility secured from the African Development Bank (AfDB) to support the National Agricultural Growth Scheme. Parliamentary investigation found that nearly $100 million had already been disbursed but the funds had not been transferred to implementing agencies responsible for distributing agricultural inputs. Another component came from a loan provided by the Japan International Cooperation Agency JICA, amounting to 15 billion Japanese Yen. The first tranche of 12 billion Yen (about N 118.96 billion) had already been disbursed in 2025, yet reports suggested that the funds remained within government accounts rather than reaching agricultural programmes. For farmers, the consequences were immediate and measurable. Delays in releasing fertilizer and seed support meant that planting windows were missed in several regions. Agricultural output projections were revised downward, and the disruption threatened subsequent farming cycles. What was designed as a response to Nigeria’s food security crisis risked becoming another example of how bureaucratic inertia can undermine development policy. These cases raise an uncomfortable possibility: sometimes development funds do not disappear through corruption but through administrative paralysis that prevents them from reaching those who need them most.

Development Projects and the Transparency Imperative

These cases do not exist in isolation. They are part of a broader pattern affecting several donor‑supported programmes across Nigeria’s development landscape. The Nigeria Erosion and Watershed Management Project, financed largely by the World Bank, aimed to combat severe environmental degradation and flooding. While the project delivered several successful interventions, independent evaluations repeatedly highlighted issues with delayed implementation, procurement disputes, and weak monitoring of contractors responsible for site rehabilitation. Similarly, parliamentary hearings have examined aspects of Nigeria’s solar electrification initiatives implemented through the Rural Electrification Agency. These programmes, supported by international climate and energy financing, were designed to expand electricity access through solar mini‑grids and standalone systems. However, questions have emerged regarding contractor selection, verification of installations, and the transparency of project monitoring systems. Accountability concerns have also surfaced within the National Social Investment Programme (NSIP), which includes the Conditional Cash Transfer scheme intended to support vulnerable households. Audits and legislative reviews have raised questions about beneficiary databases, payment transparency, and financial management structures. Environmental programmes linked to global climate initiatives have not escaped scrutiny either. Nigeria’s participation in the Great Green Wall initiative, a regional effort aimed at combating desertification across the Sahel, has experienced significant delays and concerns about how allocated resources are utilised at state and local levels. Taken together, these cases suggest that the challenges confronting development finance in Nigeria are structural rather than episodic. They reflect deeper institutional weaknesses that cut across sectors.

The SDG 17 Paradox: Partnerships Without Accountability

The recurring controversies surrounding donor‑funded projects highlight a fundamental tension within the global development framework. SDG 17 emphasises partnerships as the central mechanism for achieving development outcomes: governments, international institutions, civil society organisations, and private sector actors are expected to collaborate in mobilising resources and expertise. However, the Nigerian experience reveals a paradox. Partnerships can mobilise billions of dollars in financing while still struggling to guarantee accountability once funds enter national systems. Financial commitments are celebrated, yet monitoring mechanisms remain fragmented. Multiple institutions share responsibility, yet no single entity maintains comprehensive oversight. For citizens and communities, this creates a troubling disconnect. Development partnerships produce large funding announcements and ambitious project launches, but the tangible improvements in infrastructure, food security, or environmental protection may be slower or more limited than expected. When this happens repeatedly, the credibility of development partnerships themselves begins to erode. SDG 17 was intended to strengthen cooperation in pursuit of measurable progress. Yet without strong accountability mechanisms, partnerships risk becoming mere vehicles for financial mobilisation rather than instruments of transformative change.
