食品・食事へのカーボンラベリングが消費者選択に与える影響を検討した予備的レビュー。仮想シミュレーション研究では二桁台のCO2削減可能性が示されたが、実店舗での実証研究では2〜5%と控えめだった。信号色などの評価型表示がより効果的とされる。研究数は少なく、事業者関与と政策介入の必要性を指摘する。
English
A preliminary review of 12 studies on whether carbon labeling of food shifts consumer choice. Virtual simulation studies suggest double-digit CO2 reductions, but real-world retail studies show only 2-5% effects. Rating-based labels (e.g., traffic lights) appear more effective. More research and business/government engagement are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では食品表示・環境表示の枠組みが限定的で、カーボンフットプリント制度やScope3算定の実務と接続しうる。消費者の低炭素選択を促す表示設計は、企業の脱炭素コミュニケーションやSSBJ開示の補完情報として示唆を与える。
In the global GX context
Carbon labeling sits at the consumer-facing edge of disclosure infrastructure, complementing TCFD/ISSB corporate reporting with product-level signals. The finding that rating-based labels outperform numeric ones informs CSRD-linked labeling debates and greenwashing-avoidance design globally.
👥 読者別の含意
🔬研究者:カーボンラベルの効果測定における仮想研究と実店舗研究の乖離を整理した出発点として有用。
🏢実務担当者:食品・小売のブランドは、評価型ラベル設計と実店舗での限定的効果を踏まえた表示戦略を検討できる。
🏛政策担当者:カーボンラベルの普及には事業者関与と政策支援が必要という示唆は、表示制度設計の参考になる。
📄 Abstract（原文）
Abstract: Carbon labeling involves placing written or pictorial information on packaging, menus, or price tags to inform consumers about the carbon (CO2 ) emissions associated with the entire life cycle of a product or service, thereby empowering them to make environmentally conscious purchasing choices. Various carbon labeling practices are in use, but there is limited understanding about their effectiveness in impacting consumer choice. Method: A preliminary review examining the effectiveness of carbon labeling was conducted by searching major scientific literature databases. Quantitative studies on data on the reduction in CO2 emissions achieved through the provision of carbon labeling of meals were searched and examined. Results: Twelve studies were identified, six utilized computer-based virtual consumer choice simulation and six were conducted in real-world retail environments. Studies utilizing virtual simulations demonstrated potential double-digit reductions in CO2 output, but real-life studies identified far much modest reductions of only 2-5%. Labeling using rating-based systems, such as with traffic lights, was identified as more effective in directing consumer choice. Discussion: This preliminary literature review demonstrates that carbon labeling has the potential to direct consumers toward purchasing lower-carbon emission products. However the relatively small number of studies on this topic indicates the need for further research. Clearly, greater business engagement, and possible government intervention, is needed to advocate for carbon labeling and ensure its wider use.
