众所周知，粮食生产和消费会对环境产生重大影响。在本工作中，生命周期评估方法用于对瑞士一家大型零售商的34种水果和蔬菜进行环境评估，旨在为零售商提供环境决策支持，并建立也适用于其他案例研究的生命周期清单（LCI）。 LCI 包括苗木生产、农业机械使用、温室供暖燃料、灌溉、化肥、杀虫剂、进出瑞士和瑞士境内的储存和运输。结果表明，食用时令水果和蔬菜可以最大程度地减少环境影响，其次是减少飞机运输。如果不涉及使用化石燃料的温室供暖，那么在当地采购水果和蔬菜只是减少碳足迹的一个好策略。用水量的影响取决于农业生产的地点。对于一些作物，观察到碳足迹和引起的水胁迫之间的权衡。零售商使用这些结果来支持采购决策并改进供应链管理。
Food production and consumption is known to have significant environmental impacts. In the present work, the life cycle assessment methodology is used for the environmental assessment of an assortment of 34 fruits and vegetables of a large Swiss retailer, with the aim of providing environmental decision-support to the retailer and establishing life cycle inventories (LCI) also applicable to other case studies. The LCI includes, among others, seedling production, farm machinery use, fuels for the heating of greenhouses, irrigation, fertilizers, pesticides, storage and transport to and within Switzerland. The results show that the largest reduction of environmental impacts can be achieved by consuming seasonal fruits and vegetables, followed by reduction of transport by airplane. Sourcing fruits and vegetables locally is only a good strategy to reduce the carbon footprint if no greenhouse heating with fossil fuels is involved. The impact of water consumption depends on the location of agricultural production. For some crops a trade-off between the carbon footprint and the induced water stress is observed. The results were used by the retailer to support the purchasing decisions and improve the supply chain management.
