本研究は、LEAP-MESSAGE統合フレームワークを用いて、中国の異なるNDCシナリオ下での天然ガス需要経路を評価した。2035年の気候制約強化により、天然ガスからの移行が加速され、需給協調調整シナリオではピーク需要が最大23%削減される。需要削減は供給側調整では電力部門に集中するが、協調調整では産業・建築・運輸部門に拡大する。
English
This study uses an integrated LEAP-MESSAGE framework to assess China's natural gas demand pathways under different NDC scenarios. It finds that stronger 2035 climate constraints accelerate the transition away from natural gas, with peak demand reductions of up to 23% under coordinated supply-demand adjustment. Demand reductions are concentrated in the power sector under supply-side adjustment but extend to industry, buildings, and transport under coordinated adjustment.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策でも、天然ガスは移行燃料として位置づけられている。本論文の中国事例は、より強い気候目標が天然ガス需要の早期減少をもたらす可能性を示しており、日本のエネルギー政策やLNG調達戦略に示唆を与える。
In the global GX context
This paper provides a rigorous scenario analysis for China's natural gas demand under tightened NDC targets. It shows that stronger mid-term climate constraints can significantly reshape fossil fuel demand pathways, offering insights for global energy transition modeling and policy design.

📄 Abstract（原文）
China’s updated Nationally Determined Contributions announced in 2025 strengthen mid-term emission-reduction requirements while maintaining the 2030 peaking objective and the long-term carbon-neutrality target for 2060. Given its system support role and sensitivity to methane emissions, natural gas demand may be reshaped under the new climate constraints. This study develops an integrated LEAP-MESSAGE framework to assess China’s natural gas demand pathways over 2021–2060, in which LEAP is used to project end-use energy demand and MESSAGE is used to optimize the least-cost energy supply system. Four scenarios are compared: business as usual (BAU), a baseline pathway under the existing 3060 targets (NDC3060), a supply-side adjustment pathway under strengthened 2035 constraints (NDC3560-S), and a coordinated supply–demand adjustment pathway (NDC3560-SD). In the early stage of non-fossil energy expansion, natural gas partly serves as a flexible balancing and peaking resource for variable renewable energy integration; however, under stronger 2035 climate constraints, this transitional role is progressively weakened as non-fossil deployment and end-use substitution accelerate. The results show that the existing 3060 pathway responds weakly to the 2035 climate target, with the non-fossil energy share reaching approximately 27% by 2035 and greenhouse gas reductions failing to meet the required 7–10% decline. The natural gas demand outcomes strongly depend on the policy implementation pathway. Under supply-side-oriented adjustment, peak timing remains broadly unchanged and peak demand declines by approximately 6.5%, whereas coordinated supply–demand adjustment induces an earlier peak around 2030 and reduces peak demand by approximately 23%. Sectoral analysis further shows that demand reductions are concentrated in the power sector under supply-side adjustment but extend to industry, buildings, and transport under coordinated adjustment.
