Brief Description
Food accounts for 13% of cities’ carbon emissions every year. The “C40:Good Food Cities” Accelerator aims to reduce the carbon footprint of food in cities by promoting plant-based diets and reducing food waste. New York City is part of this effort through its Health + Hospitals system, which prepares 15,000 meals daily for public hospitals and nursing homes. The initiative focuses on providing culturally relevant, plant-based meals and has seen significant patient acceptance. The program is part of a larger effort, which includes 96 global mayors, to combat climate change and promote healthy, equitable communities. Key activities include developing plant-based menus, educating patients, and monitoring and adjusting meal offerings based on feedback.
