Nigeria’s borrowing through green bonds increased by N47.36bn within one year, signalling the Federal Government’s growing shift toward climate-focused financing as it seeks alternative funding sources for sustainable development projects and economic diversification.
Data obtained from the Debt Management Office showed that the Federal Government’s total green bond stock rose significantly from N15bn as of December 31, 2024, to N62.36bn by December 31, 2025. The increase reflects one of the fastest growth rates among Nigeria’s domestic debt instruments, even though green bonds still account for a relatively small portion of the country’s total debt profile.
Green bonds are specialised debt instruments issued to raise funds specifically for environmentally sustainable projects. Unlike conventional bonds, proceeds from green bonds are tied directly to projects with measurable environmental and climate-related benefits such as renewable energy, clean transportation, sustainable agriculture, environmental protection, and climate adaptation initiatives.
Despite the sharp increase in issuance, green bonds represented only 0.02 per cent of Nigeria’s total domestic debt in 2024 before rising modestly to 0.08 per cent in 2025. During the same period, Nigeria’s overall domestic debt stock expanded from N70.41tn to N80.49tn, driven mainly by conventional Federal Government bonds and Treasury Bills.
FGN bonds remained the dominant borrowing instrument, accounting for nearly 79 per cent of domestic debt in 2025, while Nigerian Treasury Bills represented more than 17 per cent. However, analysts say the growth in green bonds demonstrates a deliberate attempt by the government to align public borrowing with environmental sustainability and long-term economic resilience.
Findings by The PUNCH showed that the Federal Government’s Sustainable Bond Framework, released in March 2025, now serves as the policy foundation guiding the issuance of green, social, and sustainability bonds in Nigeria. The framework is jointly implemented by the Federal Ministry of Environment, the Federal Ministry of Finance, and the Debt Management Office.
Under the framework, the Federal Government outlined plans to build a more resilient and diversified economy through investments in renewable energy, local manufacturing, clean transportation systems, and climate-resilient infrastructure.
Government officials explained that sustainable bonds are designed to fund projects capable of delivering clear environmental and social benefits while helping Nigeria transition toward a low-carbon economy. The framework further emphasised that funds raised through the programme would be strictly allocated to approved green and social projects rather than general government spending.
According to the policy document, proceeds from every sustainable bond issued by the Federal Government are expected to be ring-fenced and tied directly to specific projects with measurable developmental impact. Authorities noted that the initiative is intended to support climate-resilient growth while strengthening investor confidence in Nigeria’s environmental financing strategy.
Eligible projects under the programme include solar mini-grid deployment, renewable energy expansion, sustainable agriculture schemes, clean transportation infrastructure, environmental conservation, and climate adaptation projects aimed at reducing the effects of climate change on vulnerable communities.
The framework also links Nigeria’s green bond strategy to broader national climate commitments, including the country’s Nationally Determined Contributions and Agenda 2050 development plan, both of which target economic sustainability, lower carbon emissions, and environmental protection.
To ensure accountability and transparency, the framework established strict monitoring mechanisms for the utilisation of green bond proceeds. Government agencies responsible for implementing projects are required to submit quarterly progress reports, while all funds are expected to be managed through dedicated accounts reserved specifically for approved projects.
Officials further warned that any diversion or misuse of green bond funds would immediately trigger sanctions, including suspension of further disbursements. The oversight structure places project selection responsibilities on the Federal Ministry of Environment, while the Ministry of Finance integrates sustainable bond issuance into Nigeria’s borrowing strategy and the DMO oversees fund management and debt issuance processes.
The framework also stated that Nigeria’s sustainable bond programme was designed in line with internationally recognised standards, including the International Capital Market Association’s Green Bond Principles, Social Bond Principles, and Sustainability Bond Guidelines. Independent verification and external reviews are also incorporated to strengthen credibility and compliance with global sustainability benchmarks.
Meanwhile, the Federal Government has announced plans to further deepen climate financing efforts by raising an additional N500bn through green bond issuance in 2026.
Minister of Environment, Balarabe Lawal, disclosed this following Nigeria’s participation at the Abu Dhabi Sustainability Week, explaining that the proposed issuance demonstrates the government’s commitment to scaling up climate financing while reducing dependence on oil revenues and conventional borrowing structures.
According to the minister, proceeds from the planned N500bn green bond issuance will be directed toward environmental protection projects, renewable energy development, climate adaptation programmes, sustainable agriculture, and other strategic initiatives aimed at accelerating Nigeria’s transition toward a greener and more sustainable economy.
The government also believes that expanding green financing will attract more international investors interested in sustainable investment opportunities while positioning Nigeria as a key player in climate-focused economic transformation across Africa.
