本論文は、1994年から2020年までの欧州諸国における個人消費ベースの炭素排出量を、都市密度レベル別に分析した。結果、排出量は全体的に減少傾向にあるが、国際目標には達していない。南欧・東欧では都市の排出量が高く、西欧では低い。構造分解分析により、交通・エネルギー部門の都市集約化が排出効率に影響していることが示された。
English
This paper analyzes personal consumption-based carbon footprints in European countries from 1994 to 2020, focusing on urban vs rural areas. Emissions are generally declining but remain above targets. Urban emissions are higher in Southern and Eastern Europe, lower in Western Europe. Structural decomposition analysis reveals differing drivers across regions, with transport and energy densification reducing carbon efficiency in Western Europe.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の都市と地方の炭素排出構造を考えるうえで参考になる。特に、運輸・エネルギー部門の集約化による排出効率低下は、日本でも都市部の再開発やエネルギー消費の最適化に示唆を与える。
In the global GX context
This longitudinal study on European carbon footprints provides a methodological template for analyzing consumption-based emissions over time. The findings on urban density and carbon efficiency are relevant for ISSB/TCFD disclosures that require trend analysis. The decomposition approach can be applied to other regions.

📄 Abstract（原文）
Although urban density is expected to reduce emissions related to local transportation and energy consumption, consumer carbon footprints, which cover all life cycle emissions caused by the consumption of goods and services, tend to be highest in cities and lower in rural areas. However, there is little research into how this might be changing over time. As such, longitudinal studies are important to understand factors driving emission changes, trajectories, and transitions not apparent from the results of a single year. Here, we conduct personal consumption-based emission footprints at different levels of urban density for European countries between 1994 and 2020. The results show a generally declining picture of emissions and with inter-country convergence, although at levels consistently above those required to hit international emission targets. Emissions are higher in cities in Southern and Eastern Europe, with slight decreases in these differences over time, but lower in Western Europe. The driving forces of changes in relative emissions are unravelled using structural decomposition analysis, which highlights differing pictures between the three regions. This is further illuminated through the key densification sectors of transport and energy, which implies that, despite lower emissions overall, there has been a strong decrease in the carbon efficiency from urban living in Western Europe. The work contributes to understanding the role of urban type on emissions and unravels distinct pictures that might reflect differences in development trajectories over time.
