食品供应链持有大量的具体化碳排放，需要减少和中和。这项研究旨在探索英国八个地区和组成联合王国(UK)的四个国家在当地范围内与家庭食物消费相关的历史温室气体(GHG)排放量。英国的伊特韦尔指南被用来探索在整个研究地区向更健康的饮食过渡的情况下，排放和食品成本的潜在变化。这些排放量是根据Covid大流行出现之前，即2001年至2018年期间的食物消费数据计算的。空间数据分析被用来探索研究区域与研究期间的排放量是否有任何显著的相关性。结果表明，在所探索的情景中，所有研究地区的温室气体排放量都有可能减少。进一步的影响包括在研究期间，大多数地区的家庭食品成本降低。然而，研究区域之间缺乏显著相关性的一致趋势。这项研究的结论是，地方或区域政策制定应优先于国家法规，以实现更健康的饮食，既碳中性，又家庭负担得起。
Food supply chains hold significant embodied carbon emissions that need to be mitigated and neutralized. This study aimed to explore the historical Greenhouse Gas (GHG) emissions associated with household food consumption at a local scale i.e. across the eight English regions and the four nations that comprise the United Kingdom (UK). UK EatWell guidelines were used to explore the potential change in emissions and food costs in a scenario of transitions to healthier diets across the study areas. These emissions were calculated based on food consumption data before the advent of the Covid-pandemic i.e. between the years 2001 and 2018. Spatial data analysis was used to explore if the study areas had any significant correlations with respect to the emissions during the study period. The results displayed a potential reduction in GHG emissions for all study areas in the explored scenario. Further impacts include a reduction in household food costs across a majority of the areas during the study period. However, a consistent trend of significant correlations among the study areas was absent. This study concludes that local or regional policymaking should take precedence over national regulations to achieve healthier diets that are both carbon-neutral and affordable for the households.
