Mainstage Session | Food Waste: The Past, Present, and Future

Bold action to tackle food waste reduction is more urgent than ever. From rising food prices and ongoing labor shortages, to supply chain disruptions and the surging carbon footprint of discarded food — there is a unique opportunity to influence behavior around proper food management and the food system is rising up to meet this moment. We have come far in just the last three years, but a 50% reduction goal is still a long way off. Featuring a 20-minute introduction from Dana Gunders, followed by a three 15min series of keynotes, this session will showcase different perspectives on food waste — where we’ve come, where we are now, and what needs to happen to get to 2030.
