母乳育児と商業用粉ミルクの環境負荷を比較したレビュー。粉ミルクは乳製品生産・加工・包装・物流を通じ、世界で年約59〜75億kg-CO2eを排出すると推計される。気候ショックが母乳育児を損ない粉ミルク依存を高める悪循環を指摘し、有給育児休暇や職場の搾乳支援、緊急時の授乳支援継続を政策提言として示す。
English
This review compares environmental burdens of breastfeeding versus commercial milk formula, estimating 5.9-7.5 billion kg CO2e added annually by formula use in infants under 6 months. It identifies a reinforcing feedback loop where climate shocks undermine breastfeeding and increase reliance on resource-intensive substitutes. Policy levers include paid maternity leave, workplace lactation protections, and emergency lactation support.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では少子化・女性就業率上昇と授乳継続の両立が課題で、育児休暇制度や職場環境整備の議論に環境負荷の視点を加える材料となる。ただしSSBJ・有報・TCFDなど企業開示制度との直接の接続は薄い。
In the global GX context
While outside mainstream TCFD/ISSB/CSRD disclosure frameworks, this work broadens the boundary of climate mitigation to health and care systems, offering a novel angle for transition planning and social co-benefits that global sustainability scholarship increasingly recognizes.

📄 Abstract（原文）
Infant feeding practices have environmental consequences that are largely absent from climate policy discussions. Breastfeeding relies on maternal metabolism and local support systems, whereas commercial milk formula depends on dairy production, industrial processing, packaging, and extensive supply chains. Comparative analyses report higher greenhouse-gas and water burdens for commercial milk formula than for breastfeeding. Globally, commercial milk formula use among infants under 6 months of age adds roughly 5.9-7.5 billion kg of carbon dioxide equivalent annually. Pumping and bottle-feeding add material, electricity, and cleaning-related burdens relative to feeding at the breast, but available evidence generally indicates lower impacts than commercial milk formula, although estimates depend strongly on assumptions about maternal diet and pumping practices. Climate change and water insecurity can also threaten breastfeeding through heat stress, food insecurity, and disruptions during disasters and emergencies. Moreover, uncontrolled formula donations during upheavals, while well-intended, impede continuation of breastfeeding. Collectively, these pressures can generate a reinforcing feedback loop: climate shocks undermine breastfeeding, increasing reliance on resource-intensive substitutes that further strain water and energy systems. Recognizing breastfeeding as both a mitigation and resilience issue highlights co-benefits for maternal and child health and climate action and points to practical policy levers, including paid maternity leave, workplace lactation protections, responsible marketing of commercial milk formula, and continuity of lactation support during emergencies that are needed to align optimal infant feeding with climate adaptation planning.
