Examining the case of EU27 countries is vital for evaluating the environmental Kuznets curve hypothesis but from the food waste perspective. Most European countries are the world's most economically developed and environmentally conscious. Additionally, as the EU might have relatively homogenous institutional and regulatory frameworks, our analysis can help identify common patterns and trends across these countries, allowing us to draw more generalizable conclusions about the relationships between socioeconomic characteristics and food waste behavior. Finally, the disaggregation of total food waste into households and the general food supply chain (primary production and manufacture of food products and beverages, restaurants and food services, and retail and other distribution of food) can inform policy interventions and strategies to promote sustainable development and reduce environmental degradation based on food waste in developed and developing countries.
