　　由于食物浪费问题的重要性、相关性和复杂性，食物浪费在过去十年中越来越受到社会的广泛关注。根据欧盟委员会的数据，欧盟每年大约浪费8800万吨食物。这相当于每人浪费173公斤食物，相关费用约为1430亿欧元。食物浪费问题导致了严重的伦理、环境和经济后果。首先，食物浪费产生了伦理道德问题，据统计，当前世界上有8.7亿人患有慢性营养不良，食物浪费可以用来缓解全球饥饿问题。第二，食物垃圾会产生大量的温室气体，估计相当于33亿吨二氧化碳。此外，用于粮食生产的大量化肥和资源(例如，水、土壤、人力)导致了气候变化。最后，对个人乃至国家经济而言，食物浪费意味着金钱损失。因此，食物浪费是一个亟待应对的社会挑战。

　　ABSTRACT

　　Food waste is a critical issue with multiple ethical, environmental and economic consequences. The aim of this study is to investigate which factors most affect food waste and determine what actions are undertaken to prevent it at the household level. The study, while privileging a behavioural perspective, focuses on the overall consumption process, from purchasing through final food consumption, thus assuming a broad perspective. The data for this study were collected among Italian, Spanish and English populations using three public online questionnaires administered from January to September 2017. This resulted in a total of 3323 usable questionnaires referring to a sample population aged between 18 and 35 years. As for the main motivation to waste food, the research findings provide strong evidence of the importance of in-store behaviour and food management at home in reducing the frequency of food waste in all the three countries examined. As for the actions preventing food waste, the consumption of leftovers appears as a relevant determinant in minimising food waste. The findings confirm that food waste is a complex issue that requires a broad approach of analysis considering several factors simultaneously. The study also provides further insights regarding the relationship between eating outside the home and food waste, which is a topic of debate in the extant literature. Finally, the study improves the overall knowledge about actions that prevent food waste, which have previously been poorly investigated.
