Transforming our collective appetite – creating fair food environments


Scientific Advisory Board on Agricultural Policy, Food and Consumer Health Protection (WBAE) 

Time: Thursday, 19. January 2023, 4:00 p.m. – 5:30 p.m.

Room: M8

Languages: English, German


How we eat has a major impact on our individual health status, our quality of life and our well-being. Many of the foods we eat have a major social, environmental, climate and animal welfare footprint. In its latest expertise the Scientific Advisory Board on Agricultural Policy, Food and Consumer Health Protection (WBAE) at the Federal Ministry of Food and Agriculture (BMEL) defined policies to promote sustainability in food consumption as policies that integrate all four target dimensions: human health, social aspects, the natural environment and animal welfare. The necessary progress can only be achieved with a comprehensive transformation of today’s food system.

A crucial but underestimated key driver is the creation of fair food environments. The food environment encompasses the entire behavioural process, including exposure, access, choice and consumption. Fair food environments are attuned to our human perception, decision-making possibilities and behaviour; and they are more health-promoting and have greater social, ecological and animal-welfare compatibility and thus contribute to sustaining the livelihoods of the world’s current and future generations.

Thereby, this panel aims at discussing how to create fair food environments as well as an integrated food policy with leading international experts from science, industry and policy. What is the status quo? What can be learnt from food policies in other countries? Which role can the food industry play?
