食品的生产、加工和运输，特别是动物性产品，给地球带来了巨大的环境负担。目前的食品供应系统往往构成工业化城市社区碳排放总量的相当大一部分。城市粮食生产（UFP）是一种可能减少粮食排放的方法。同时，转向以植物为主的饮食，以满足营养蛋白质的摄入量，是减少食物碳排放的有效方法。考虑到与畜牧产品生产相关的高土地使用，这种转变将促使社区的粮食需求更倾向于通过当地生产来满足。因此，在未来低碳城市的设计过程中，两者的结合应用值得探索。这项工作介绍，描述和演示FEWprint平台的饮食转变组件，这是一个面向设计师的用户友好的UFP评估平台，围绕更广泛的评估，转变和设计三管齐下的策略构建。对于三个街区，在阿姆斯特丹，贝尔法斯特和底特律，上下文消费和国家特定的环境足迹数据被应用到模拟理论上的社区范围内的饮食从传统的素食饮食转变，同时保持蛋白质摄入量的平衡。结果显示，从总体上看，底特律的碳减排潜力最大（-916千克CO2当量/人/年），其次是贝尔法斯特（-866千克）和阿姆斯特丹（-509千克）。相对而言，贝尔法斯特的碳减排潜力最大（-25%），其次是阿姆斯特丹（-15%）和底特律（-7%）。FEWprint可用于生成关于饮食适应的碳影响的初步数字，并可用于初步指示城市社区中UFP的潜力。
The production, processing, and transportation of food, in particular animal-based products, imposes great environmental burden on the planet. The current food supply system often constitutes a considerable part of the total carbon emissions of urban communities in industrialised cities. Urban food production (UFP) is a method that can potentially diminish food emissions. In parallel, a shift towards a predominantly plant-based diet that meets the nutritional protein intake is an effective method to curtail carbon emissions from food. Considering the high land use associated with the production of animal-based products, such a shift will prompt a community food demand that is more inclined to be satisfied with local production. Therefore, during the design process of a future low-carbon city, the combined application of both methods is worth exploring. This work introduces, describes, and demonstrates the diet shift component of the FEWprint platform, a user friendly UFP assessment platform for designers that is constructed around the broader three-pronged strategy of evaluation, shift, and design. For three neighborhoods, in Amsterdam, Belfast, and Detroit, the contextual consumption and country-specific environmental footprint data are applied to simulate a theoretical community-wide diet shift from a conventional to a vegan diet, whilst maintaining protein intake equilibrium. The results show that in total terms, the largest carbon mitigation potential awaits in Detroit (−916 kg CO2eq/cap/year), followed by Belfast (−866 kg) and Amsterdam (−509 kg). In relative terms, the carbon reduction potential is largest in Belfast (−25%), followed by Amsterdam (−15%) and Detroit (−7%). The FEWprint can be used to generate preliminary figures on the carbon implications of dietary adaptations and can be employed to give a first indication of the potential of UFP in urban communities.
