土地利用変化（LUC）による炭素排出（E_LUC）は産業革命以降の人為排出の約3分の1を占める。本研究は世界と中国の年次E_LUCをシミュレーションし、1913年までの増加、1913〜1992年の移行、1992年以降の減少という3段階を特定。累積E_LUCと化石燃料・産業排出（E_FOS）を比較し、気温上昇との関係を分析した。中国では産業排出が農業排出を上回る転換が世界より遅いことを示す。

Land-use change (LUC) carbon emissions (E_LUC) account for about one-third of anthropogenic emissions since industrialization. This study simulates annual E_LUC globally and in China, identifying three phases: increase before 1913, transition 1913-1992, and decline after 1992. It compares cumulative E_LUC with fossil fuel and industry emissions (E_FOS) and analyzes their relationship with global temperature anomalies. In China, the transition to industrial dominance occurs later than globally.

日本のGX文脈において
日本では土地利用変化由来排出は小さいが、SSBJ開示におけるScope 1・2の算定や、サプライチェーン排出（Scope 3）の間接的な評価に示唆を与える。また、気候変動政策の基礎データとして、日本の長期戦略や適応策の検討に参考となる。
In the global GX context
Globally, this study contributes to understanding the role of land-use change in national GHG inventories and climate mitigation targets under the Paris Agreement. It provides a long-term perspective that can inform IPCC assessments and national climate strategies, particularly for countries with significant land-use emissions.
👥 読者別の含意
🔬研究者:Provides a long-term dataset and phase analysis of LUC emissions useful for climate modeling and carbon cycle research.
🏢実務担当者:Limited direct application, but may inform corporate land-use related disclosure and Scope 3 categories like land use change.
🏛政策担当者:Relevant for national GHG inventory compilation and setting mitigation targets that include land-use sector.
📄 Abstract（原文）
Land-use change (LUC)-induced carbon emissions ( E LUC ), defined as net carbon emissions and removals, have accounted for approximately one-third of global anthropogenic carbon emissions since industrialization. The complex temporal evolution of annual E LUC observed globally and in China underscores land-use change as a critical lever for climate mitigation. Investigating E LUC facilitates a deeper understanding of climate change dynamics. LUC—encompassing deforestation, urbanization, and agriculture across diverse regions and territories—collectively provides the optimal fingerprint of the system. Through simulations of annual E LUC over time, we identify three distinct phases in its temporal evolution: an increasing phase before 1913, a transitional phase from 1913 to 1992, and a declining phase after 1992. Cumulative E LUC at global and China scales is examined and compared with cumulative emissions from fossil fuels and industry ( E FOS ). The temperature dependence of cumulative E LUC and cumulative E FOS is derived. Analysis of the relationship between cumulative E LUC , cumulative E FOS (1880–2024), and global annual mean temperature (AGMT) anomalies relative to the 1880–1920 pre-industrial baseline reveals that both E LUC and E FOS increase with AGMT. However, cumulative E LUC approaches a plateau when AGMT exceeds 0.9 °C, whereas cumulative E FOS does not. The temporal evolution of cumulative E LUC and cumulative E FOS is further investigated. Prior to the Industrial Revolution, the global economy was predominantly agrarian, resulting in substantial cumulative E LUC . Since 1980, E FOS have exhibited a higher annual growth rate than E LUC , ultimately leading to industrial emissions surpassing agricultural emissions. In China, this transition occurs later.
