エチオピアのエネルギー起源CO2排出量をLMDI分解とLEAPシナリオ分析で評価。経済活動と人口増加が排出を押し上げたが、エネルギー原単位改善が一部相殺。NDC 3.0目標達成には適度な政策努力で可能だが、ネットゼロには調理・運輸部門の変革と約1,570億ドルの気候資金が必要。
English
This study uses LMDI decomposition and LEAP scenario modeling to assess Ethiopia's energy-related CO2 emissions. Economic activity and population drove increases, while intensity improvements offset partially. NDC 3.0 targets are achievable with moderate effort, but net zero by 2050 requires transformative changes in cooking and transport, backed by ~US$157 billion in climate finance.

日本のGX文脈において
エチオピアは伝統バイオマス依存度が高く、NDC目標達成に向けた統合モデル分析は、日本の国際協力や途上国支援における脱炭素計画の参考となる。特にオフグリッド再生可能エネルギーや調理用燃料転換は、アフリカ全域の気候政策に示唆を与える。
In the global GX context
This paper provides a rigorous modeling framework for a least developed country's decarbonization, relevant for global NDC tracking and climate finance discussions. It demonstrates the critical role of residential energy efficiency and renewable electrification in achieving net zero, offering a template for other biomass-dependent economies.

📄 Abstract（原文）
Ethiopia has sustained rapid economic growth (6–10% annually) but remains heavily dependent on traditional biomass (88% of final energy), with electrification at only 55% as of 2022. Ambitious climate targets under NDC 3.0 (70.3% reduction below BAU by 2035) and the Long Term Low Emissions Development Strategy (net zero by 2050) demand rigorous decarbonization planning. This study develops an integrated LMDI LEAP framework to assess Ethiopia’s decarbonization pathways to 2050, bridging historical driver decomposition with dynamic scenario simulation. Methods: Logarithmic Mean Divisia Index (LMDI) decomposition quantifies drivers of energy related CO₂ emissions (2005–2020). The Long range Energy Alternatives Planning System (LEAP) models four scenarios (BAU, Current Policies, Announced Policies Scenario – APS, and Net Zero Emissions – NZE) from 2022 to 2050. LMDI reveals that economic activity (+58%) and population (+38%) drove emission increases, while energy intensity improvements (−45%) partially offset growth – a weak decoupling status (elasticity 0.54). Under BAU, emissions reach 214 MtCO₂e by 2060. APS reduces emissions to 65 MtCO₂e in 2035 (42% below BAU), approaching NDC 3.0 unconditional targets. NZE achieves energy sector emissions of 2.9 MtCO₂e by 2050 (>90% reduction) through aggressive efficiency (improved cookstoves reduce household demand by 55–57%), full renewable electrification, and end use switching. Ethiopia can meet NDC 3.0 targets with moderate policy effort, but net zero requires transformative interventions, particularly in residential cooking and transport, backed by ~US$157 billion in climate finance. Prioritize energy intensity measures, scale solar/wind/geothermal, electrify end uses, and mobilize international support.
