https://www.c40.org/news/good-food-cities/#:~:text=The%20cities%20signing%20the%20C40,World%20Mayors%20Summit%20in%20CopenhagenResearch released by C40 Cities in June 2019, revealed that food is amongst the biggest sources of consumption-based emissions from cities. Eating a sustainable diet and avoiding food waste could cut greenhouse gas emissions from the food we eat by more than 60%. Research by The EAT-Lancet Commission released in January 2019 found that if adopted universally, the ‘Planetary Health Diet’ would dramatically reduce emissions, provide a balanced, nutritional diet for 10 billion people, and save 11 million lives each year. The planetary health diet is comprised of balanced and nutritious food providing up to 2,500 calories a day for all adults, not to exceed 16kg of meat per person per year or ~300g per week, and 90kg of dairy per person per year or ~250g per day, and low in ultra-processed food. A planetary health plate should consist of approximately half a plate of vegetables and fruits; the other half should consist of primarily whole grains, plant protein sources, unsaturated plant oils, and (optionally) modest amounts of animal sources of protein.
Under the C40 Good Food Cities Declaration, cities commit to:
Align food procurement policies to the Planetary Health Diet ideally sourced from organic agriculture
