About this sector

Our global food system is broken: one third of all food is wasted, yet many people around the world suffer from food insecurity. Food is among the largest drivers of the global climate crisis. Food insecurity is also one of the biggest impacts of the COVID-19 pandemic.

Most of the world’s food is consumed in urban areas, giving cities the power to deliver transformative change. C40 works with cities to develop healthy, equitable and accessible food systems that also reduce food loss and waste. 

Through the C40 Good Cities Accelerator, 16 cities from around the world have signed on to deliver sustainable food policies and achieve a ‘Planetary Health Diet’ for all by 2030.
