中国の家計消費に伴うCO2・PM2.5・NOx・SO2排出のうち、約84%が行動慣性によりロックインされていることを実証。食品が最も高く約97%、次いで住居支出が84-86%。2035年までのシナリオ分析では、カーボンニュートラル政策と消費慣性の緩和を組み合わせた場合に最大の削減効果が得られると示す。需要側の系統的対策の重要性を強調。
English
This study quantifies habit-locked emissions from household consumption in China, finding that nearly 84% of total household-driven CO2, PM2.5, NOx, and SO2 emissions are locked in by behavioral inertia. Food has the highest locked-in share (~97%), followed by residential expenditure (84-86%). Scenario analysis to 2035 shows that combining carbon-neutrality policies with attenuated consumption inertia yields the deepest reductions (1,285 Mt CO2, 218 kt PM2.5, 729 kt SO2, 126 kt NOx). The findings highlight the need for systematic demand-side mitigation strategies.

日本のGX文脈において
日本の家庭部門の脱炭素施策（例：省エネ家電普及、食品ロス削減）において、行動慣性の考慮が重要であることを示唆。日本のカーボンニュートラル目標達成には、需要側の行動変容を促す政策設計が不可欠であり、本研究成果はその根拠となる。
In the global GX context
This research provides empirical evidence on the role of behavioral inertia in household emissions, relevant for global demand-side mitigation strategies. It complements supply-side policies by quantifying the locked-in emissions that require systematic substitution with lower-emission alternatives, offering insights for countries designing carbon neutrality roadmaps.
👥 読者別の含意
🔬研究者:Provides a novel quantification of habit-locked emissions and scenario analysis, useful for consumption-based accounting and demand-side mitigation research.
🏢実務担当者:Highlights the importance of addressing consumer behavior in corporate sustainability strategies, especially for sectors like food and residential energy.
🏛政策担当者:Demonstrates that carbon neutrality policies must be paired with measures to reduce consumption inertia to achieve deep emission reductions.
📄 Abstract（原文）
Household consumption is a major driver of global carbon and air-pollutant emissions. As living standards rise, everyday routines become entrenched and reduce the responsiveness of demand to mitigation policies. Consumption-based accounting has traced these burdens through supply chains, yet the scale of emissions that remain locked in by behavioral inertia has stayed poorly quantified. Here we show that locked-in emissions of carbon and air pollutants account for nearly 84% of total household-driven emissions of CO 2 , PM 2.5 , NO x , and SO 2 across China, far exceeding the contribution of net consumption growth. Food exhibits the highest locked-in share (approximately 97%), followed by residential expenditure (84–86%). Per-capita habit-locked emissions peak in East and North China, with 32–53% of these emissions originating in the production systems of Nei Mongol and Shandong. Scenario analysis to 2035 reveals that under business-as-usual scenario, habit-locked CO 2 emissions peak around 2030, while habit-locked air-pollutant emissions decline, whereas the deepest and most balanced reductions, 1,285 Mt CO 2 together with 218 kt PM 2.5 , 729 kt SO 2 , and 126 kt NO x , occur only when carbon-neutrality-oriented policies are paired with attenuated consumption inertia. These findings demonstrate that efficient demand-side synergistic mitigation in China requires systematic substitution of habit-locked carbon and air-pollutant emissions with lower-emission, affordable alternatives.
