本論文は、中国・長沙市の2011～2022年のデータを用いてLMDI-STIRPATモデルを構築し、炭素排出の要因分析と将来シナリオ予測を行った。エネルギー構造は排出を抑制する一方、人口増加は排出を促進する。8つのシナリオのうち、低炭素シナリオS1のみが2030年までにカーボンピークを達成可能であり、その実現にはエネルギー消費構造の改善や産業レイアウトの最適化などの政策提言がなされた。
English
This study constructs an LMDI-STIRPAT model using 2011-2022 data for Changsha, China, to analyze driving factors of CO2 emissions and forecast future scenarios. Energy structure restrains emissions while population size drives them. Among eight scenarios, only the low-carbon scenario S1 achieves the carbon peak by 2030 at 20.37 Mt. Policy recommendations include improving energy structure and optimizing industrial layout.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の地方都市のカーボンピーク達成シナリオ分析であり、日本の自治体の脱炭素計画策定の参考になる可能性がある。ただし、中国特有のエネルギー構造や政策枠組みに基づいており、そのまま適用は困難。
In the global GX context
This paper provides a case study of urban carbon emission forecasting and scenario analysis for a Chinese city, offering insights for local climate action planning in developing regions. The LMDI-STIRPAT methodology is transferable, but specific drivers differ by context.
👥 読者別の含意
🔬研究者:Demonstrates application of LMDI-STIRPAT model for urban carbon emission forecasting and scenario analysis.
🏢実務担当者:May inform corporate sustainability teams in Chinese cities about emission reduction pathways, but limited direct applicability outside China.
🏛政策担当者:Useful for city-level carbon peak planning, especially for developing regions seeking to align with national carbon goals.
📄 Abstract（原文）
As the central city of Hunan Province, Changsha is a key to grasping how carbon emission growth is playing out and getting the peak carbon emission event to happen faster than initially planned. In this study, it adopts the data from 2011 to 2022 to build the LMDI-STIRPAT model and forecast the carbon emission trend of Changsha. Through scenario simulations, the research identifies the primary factors influencing carbon emissions, projects future emission trajectories, and determines the optimal pathways for emission reduction. The main results: (1) The energy structure restrains the growth of carbon emission, while the population size is still a big pusher that helps increase the carbon emission. (2) Out of eight forecasting situations, only situation S1 arrives at the carbon peak goal by 2030, which achieves 20.37 Mt, whereas the others vary in their delay. (3) Changsha reaches its carbon peak according to the plan in the low-carbon situation S1, making it the most effective option for emission cuts. To achieve this, the paper gives recommendations such as modifying energy consumption structure, optimizing industrial layout, and reinforcing related the policy framework supporting cities low carbon transition and explained in conclusion.
