Reducing Food Waste

Thirty percent of our global food supply is lost or wasted, and the CLF is working to advance the Sustainable Development Goals target of halving that waste. We look at this issue through the lenses of public health, food systems, equity and environment. We use an interdisciplinary portfolio of qualitative and quantitative tools to research: policy and interventions (with particular attention to unintended consequences), food distribution and donation, consumer behavior, communications, quantification and seafood waste. We also engage in the policy, practice and communications activities necessary to translate evidence to real-world impact.
