The 3-year project, launched in April 2019, and funded by Climate-KIC, is working with the City of Copenhagen and partners to translate the findings of the EAT-Lancet Commission on Food, Planet, Health into local action and interventions. The objective of ‘Operationalising Food System Targets for Health and Sustainability’ is to enable cities to set smarter and more ambitious food system targets with greater accountability and measurable benefits to climate, environment, public health, and societal well-being. The project is the first to operationalise the science, paving the way for a planetary diet. With Copenhagen as a prototype and other cities consulted throughout, the project aims to demonstrate how scientific targets for food systems can be operationalised in the city context. The project will be carried out across four integrated work packages. In conducting this work, EAT will work closely with the Potsdam Institute for Climate Impact Research (PIK), the University of Copenhagen, and the World Resources Institute (WRI) on translating the global synthesis science from the EAT-Lancet report to the local Copenhagen context. In parallel, Gehl Architects and City University of London will focus on how the built environment determines and influences people’s food consumption choices and habits, while Copenhagen House of Food will implement a series of training curricula and programs to empower kitchen staff and the public to prepare healthy and sustainable meals that are within EAT-Lancet recommendations.
