Keynote 1 • Breaking down Sustainability Silos – How Zero Waste Supports Efficiency, Health, and Decarbonization 

October 22, 2025 from 9:00 am to 9:30 am

Speaker: Speaker: Stefan Moedritzer

While Zero Waste is a worthy end goal on its own, it can be much more effective when framed as a suite of solutions that can drive cost savings, support healthy environments, and accelerate decarbonization. Stefan will share how Google has evolved its sustainable materials strategy to meet the moment, and how efforts to address food waste, reduce plastics, and reuse building materials have become integrated across Google’s real estate and operations teams.

Speaker: Stefan Moedritzer, Circularity and Embodied Carbon Lead, Google
