ABSTRACT

This work evaluates and discusses the greenhouse gas (GHG) emissions reduction potential of agroecological policies implemented in public food procurement for school canteens. Using a life cycle analysis (LCA) methodology (cradle-to-grave approach) and the information gathered from the Red Municipal de Comedores Escolares (Local Network of School Canteens) in the municipality of Ames (A Coruña, Galicia, Spain), the results show how organic production, dietary change (less animal protein), seasonal consumption, and packaging reduction, among other measures, can mitigate the climate impact of school meals. The food policies implemented in Ames have allowed mitigating the GHG emissions of local school canteens by 13.4%. Under realistic conditions, this reduction could rise to 40.6% should the agroecological transformation of the food system continue to advance.

摘要

这项工作评估和讨论了在学校食堂公共食品采购中实施的农业生态政策的温室气体 (GHG) 减排潜力。使用生命周期分析 (LCA) 方法（从摇篮到坟墓的方法）和从埃姆斯市（西班牙加利西亚拉科鲁尼亚）的 Red Municipal de Comedores Escolares（学校食堂地方网络）收集的信息，结果表明，有机生产、饮食变化（减少动物蛋白）、季节性消费和包装减少等措施可以减轻学校供餐对气候的影响。艾姆斯实施的食品政策使当地学校食堂的温室气体排放量减少了 13.4%。在现实条件下，这种减少可能会增加到 40。
