Food systems are responsible for global greenhouse gases (GHG) emissions and global terrestrial biodiversity loss. They are a significant driver of land conversion and deforestation. 

Policies that operate across the food systems can contribute both to food security and environmental sustainability. One of these cross-cutting policy fields is Public Food Procurement (PFP). Sustainable PFP policies can promote healthy diets based on sustainable food systems (including agroecology) in workplaces, schools, universities, hospitals, aged care facilities, and other public meal venues.

This Special Issue of ''Sustainability'' will collect articles from academics, researchers, and practitioners exploring innovative approaches and methods in sustainable available food procurement practice and policy, focusing on PFP policies. It aims to serve as an instrument to promote environmental sustainability and possible means to measure its impacts and areas in which research is currently lacking. The topic of sustainable public food procurement is also one that is particularly relevant to the current COVID-19 pandemic and any post-pandemic recovery.
