在这项研究中，我们基于英国不同地区和国家消费的食物配方的排放因子，估计了外出就餐的环境负担。基于食物的排放量以人均每周千克二氧化碳当量表示，并根据2001年至2018年的食物消费数据计算。使用时间序列分析来估计所有研究区域2019年和2020年的排放量。这些结果被用来估计终点对人类健康以及研究期间陆生和水生物种的影响。最后，还根据今年前11个月的现有市场数据对2020年的排放量进行了估计。这随后与早先计算的预测进行了比较，以观察新冠肺炎导致的封锁对外出就餐的影响，从而导致排放。通过采取国家以下做法，我们的目的是强调认识到这些区域之间的相似和不同及其政策影响的重要性。据作者所知，这是第一项也是唯一一项关于英国外出就餐产生的区域性食物排放的研究。
In this study we estimated the environmental burden of eating away from home based on emission factors of food recipes consumed in different regions and countries within the United Kingdom. Food based emissions were expressed in kg CO2equivalent per capita per week and were calculated based on food consumption data between the years 2001 and 2018. Time series analysis was used to estimate emissions for the years 2019 and 2020 for all study areas. These results were used to estimate the endpoint impacts on human health as well as terrestrial and aquatic species during the study period. Finally, an estimate of the emissions for 2020 was also carried out based on available market data for the first 11 months of the year. This was subsequently compared with the forecasts calculated earlier to observe the impacts of Covid-19 led lockdowns on eating out and hence the emissions. By taking a subnational approach, we aimed to highlight the importance of appreciating similarities and differences among these regions and policy implications thereof. To the best knowledge of the authors this is the first and only study focusing on regional food-based emissions from eating out in the United Kingdom.
