本研究は、ラオスのNDC目標達成に向け、CLEWsフレームワークとOSeMOSYSを用いて2020～2050年の再生可能エネルギー・交通・土地利用の連関を分析。水力が主力電源であり続ける一方、2040年以降は太陽光や廃棄物発電が有望となる。EV30%目標は経済的に可能だが、2～3輪車には政策介入が必要。全ての政策を組み合わせると排出は最小化されるが、作物生産が制限される。

This study uses the CLEWs framework and OSeMOSYS to assess the interlinkages between renewable energy, transport, and land-use in Laos from 2020-2050. Hydropower remains dominant, while solar and waste-to-energy become viable post-2040. A 30% EV target for cars is economically feasible but 2-3 wheelers require policy intervention. Combining all policies achieves lowest emissions but limits crop production. Integrated policy planning is essential.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ラオスはASEAN諸国の中でも電力構成の大部分を水力に依存する特異な国であり、本研究は途上国におけるエネルギー転換と土地利用制約のトレードオフを定量的に示している。日本企業にとっては、ラオスのバイオ燃料やEV市場への投資判断の参考となるが、直接的な制度連動性は低い。
In the global GX context
This study provides a quantitative assessment of the trade-offs between renewable energy deployment, EV adoption, and land-use constraints in a developing country context. It demonstrates the value of integrated CLEWs modelling for national energy planning, which is relevant for countries worldwide seeking to align NDCs with sustainable development goals.

📄 Abstract（原文）
Laos’ updated Nationally Determined Contribution (NDC) prioritises decarbonisation and energy sustainability, yet progress is challenged by Laos’ reliance on imported petroleum for transport. This prompts government effort to promote biofuels and electric vehicles (EVs). This study applies the CLEWs (Climate, Land, Energy, and Water systems) framework within the Open-Source Energy Modelling System (OSeMOSYS) to assess interlinkages between renewable energy, transport, and land-use in Laos over the 2020-2050 period. Four national-strategy based scenarios were modelled: (i) baseline least-cost, (ii) 10% biofuel share, (iii) combined biofuel and EV targets (30% penetration among cars and 2-3 wheelers), and (iv) combined policy scenario with cropland constraint. Results shows that hydropower remains the dominant electricity source until 2050, with solar and waste-based generation emerging as a lucrative option after 2040. Biofuels are policy-driven rather than cost-optimal, while a 30% EV target for cars is economically feasible but requires policy intervention for 2-3 wheelers. Combining all policy measures achieves the lowest emissions but limits crop production. The study suggests supporting the target with land allocation for biofuel crops, biofuel feedstock diversification, and incentives for EV. As renewables become the least-cost power source, Laos could also consider coal phase-out by 2045. Overall, findings underscore the need for integrated policy planning within the CLEWs nexus to guide future national strategies.
