本研究は、スウェーデンの約6,000人を対象に、デジタルライフスタイルの強度と消費ベースのCO2排出量の関係を実証分析した。デジタル化が排出削減に寄与するか、あるいは需要を誘発するかという議論に対し、カテゴリ別分解を用いて両効果の相殺を検証している。
English
This study empirically analyzes the relationship between digital lifestyle intensity and consumption-based CO2 emissions using survey and transaction data from about 6,000 Swedish adults. It tests whether digitalization reduces emissions through dematerialization or increases them through rebound effects, using category decomposition to disentangle the two mechanisms.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、デジタル化と脱炭素の両立が注目されるが、個人レベルの実証は乏しい。本研究成果は、日本のデジタル社会実現に向けた政策や企業のサービス設計に示唆を与える。
In the global GX context
Globally, this study contributes to the debate on digitalization and climate change by providing individual-level evidence linking digital lifestyles to consumption-based emissions, which is relevant for designing effective climate policies and understanding rebound effects.
👥 読者別の含意
🔬研究者:Provides empirical evidence on the net effect of digital lifestyles on consumption-based emissions, useful for refining models of rebound and substitution.
🏢実務担当者:May inform companies about the carbon implications of digital services and guide product design to promote low-carbon consumption.
🏛政策担当者:Highlights the need for policies that address potential rebound effects from digitalization to ensure net emission reductions.
📄 Abstract（原文）
Digitalization is reshaping how time and money are spent, with contested implications for house- holds’ behaviour and carbon footprint. One literature expects dematerialization and demobi- lization: digital services substitute for physical goods, travel, and out-of-home activities, low- ering consumption-based emissions. A second expects rebound and induced demand : time and money freed by digital activity flow back into consumption, and digital channels (e-commerce, streaming, targeted marketing) actively generate new demand, raising emissions. Existing evi- dence is dominated by top-down ICT-sector footprints and stated-preference or time-use studies; individual-level evidence linking directly measured digital lifestyle intensity to a comprehensive consumption-based carbon footprint is scarce. This study combines survey-measured digital lifestyle intensity, cardinally anchored in device-reported screen time, with transaction-based consumption-level CO2e for approximately 6,000 Swedish adults. Because both accounts may operate simultaneously and partially offset each other in the total, the adjudicating test is the category decomposition (RQ2) rather than the net gradient alone (RQ1).
