ナイジェリアの1970〜2024年データを用い、ARDL bounds testingとToda-Yamamoto因果検定でCO2排出・エネルギー消費と経済成長の動態関係を分析。長期ではCO2とエネルギー消費が成長に負の影響を与え、短期では正の影響を示しEKC仮説の初期段階と整合。CO2から成長への一方向因果を確認し、再エネ統合・カーボンプライシング・省エネ基準を政策提言として提示。
English
Using 1970–2024 Nigerian data, this study applies ARDL bounds testing and Toda-Yamamoto causality to examine CO2 emissions, energy consumption, and economic growth. Long-run effects of emissions and energy use on growth are negative, while short-run effects are positive, consistent with the EKC's early phase. It finds unidirectional causality from CO2 to growth and recommends renewables, carbon pricing, and efficiency standards for Nigeria's 2060 net-zero target.

日本のGX文脈において
日本企業のGX実務への直接示唆は乏しいが、新興国・産油国の脱炭素と成長のトレードオフを理解する材料として、グローバルサプライチェーンや移行金融の文脈で参照価値がある。
In the global GX context
This adds Nigeria-specific empirical evidence to the EKC and energy-growth literature, relevant to global transition finance and just-transition debates for fossil-fuel-dependent emerging economies. It complements ISSB/TCFD-aligned disclosure discussions by quantifying the growth-emissions trade-off in a high-vulnerability, low-access context.

📄 Abstract（原文）
Nigeria, Africa’s largest oil producer, faces significant environmental and economic challenges due to its reliance on fossil fuels, contributing 0.74% of global CO2 emissions in 2019 (354 MtCO2e), with the energy sector accounting for 60.5% of emissions. The analysis, grounded in the Environmental Kuznets Curve (EKC) and resource curse hypotheses, examines how CO2 emissions and energy consumption impact economic growth, proxied by real GDP (RGDP), alongside control variables: population growth rate (PGR), urbanization (URB), and energy prices (EP). This study investigates the dynamic relationships among carbon dioxide (CO2) emissions, energy consumption, and economic growth in Nigeria from 1970 to 2024, employing the Autoregressive Distributed Lag (ARDL) bounds testing approach and Toda-Yamamoto Granger causality tests. Findings reveal a long-run negative effect of CO2 emissions and energy consumption on economic growth, with coefficients of -80.594 and -7.374, respectively, significant at 5% and 1% levels, driven by environmental degradation and inefficiencies in energy use. In the short run, both variables positively influence growth, aligning with the EKC’s early phase. A unidirectional causality from CO2 emissions to economic growth is observed, supporting the EKC’s pollution-intensive growth path, while no causal link exists between energy consumption and growth, consistent with the neutrality hypothesis. The study highlights Nigeria’s climate vulnerability, including the 2022 floods, and its energy poverty (60–70% lack electricity access). Policy recommendations include deep decarbonization through renewable energy integration, carbon pricing, and energy efficiency standards to balance economic growth with sustainability, contributing to Sustainable Development Goals (SDGs) 7, 8, and 13. These findings bridge empirical gaps in Nigeria-specific literature, offering actionable insights for achieving the country’s net-zero target by 2060.
