日本語

本研究は、ナイジェリアの2025年税法が海洋エネルギーからの収益(海洋レント)を適切に捕捉しているかを批判的に検討する。法人税やロイヤルティ、インセンティブなどを分析し、収益捕捉の脆弱性や持続可能な開発との不整合を指摘する。最終的に、海洋レントの強化、開発基金の設置、透明性向上、ブルーエコノミーや脱石油戦略との統合を提言する。

English

This study critically examines Nigeria's 2025 Tax Act in capturing 'ocean rents' from offshore energy for sustainable development. Through doctrinal analysis, it identifies gaps in revenue capture, transparency, and alignment with sustainability goals, and recommends strengthening rent mechanisms, ringfenced funds, and integration with blue economy and post-oil transition strategies.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本はエネルギー輸入国であり、ナイジェリアのような資源国の税制は直接関係しないが、海外資源投資における租税ガバナンスやエネルギー移行策の参考になり得る。また、ブルーエコノミーの観点から海洋資源利用の持続可能性を考える上で示唆を与える。

In the global GX context

This paper contributes to the global discourse on fiscal policy for energy transition, particularly in developing resource-rich countries. It highlights challenges in aligning taxation with sustainable development and blue economy objectives, relevant for international frameworks on climate finance and just transition.

📄 Abstract(原文)

The strategic exploitation of Nigeria's offshore energy resources presents a critical opportunity for national development, yet the effectiveness of fiscal mechanisms in capturing ocean rents remains insufficiently examined within legal scholarship. In Nigeria, where offshore hydrocarbons constitute a dominant source of public revenue, the central challenge lies in optimising tax-based rent capture to finance sustainable development while maintaining investment attractiveness and economic competitiveness. This study critically interrogates the positioning of the Nigerian Tax Act as a framework for offshore energy governance, assessing its adequacy in capturing ocean rents and facilitating equitable and sustainable fiscal outcomes. Adopting a doctrinal and analytical methodology, the research examines the structure and scope of offshore taxation under the Tax Act, the effectiveness of rent-capturing instruments, and the alignment of fiscal provisions with national development imperatives. The analysis evaluates corporate income taxation, royalties, incentives, profit-based levies, and fiscal concessions in offshore energy operations, highlighting persistent gaps in revenue capture, transparency, and intergenerational equity. Drawing insight from Nigeria's fiscal regime and offshore tax governance, the study reveals that while the Nigeria Tax Act 2025 provides a formal legal basis for revenue collection, it is constrained by weak valuebased rent mechanisms, fiscal leakages, and misalignment with sustainable development objectives. The research recommends strengthening rent-capture provisions, instituting ringfenced development funds, enhancing transparency and accountability, and integrating fiscal design with national Blue Economy and post-oil transition strategies, thereby positioning offshore energy taxation as a transformative instrument for national development.
