The quality and quantity of the global food supply now and into the future are increasingly under threat. The food system contributes to one-third of greenhouse gas emissions and losses in biodiversity, to name just two consequences leading to environmental degradation. To mitigate environmental and health harms, governments around the world have instituted public policies to advance sustainability goals throughout the food system from producers to consumers. Without worldwide shifts in diets, the achievement of sustainability goals will be extremely challenging.

The availability and analysis of data on policy design and implementation plays an important role in identifying the evidence base to determine which policies are successful in the pursuit of the desired outcomes in sustainability goals, particularly in low- and middle-income countries.
