The present project will make an important contribution to the debate on climate change in the broader context of sustainable consumption by opening up a political as well as scientific discussion on possible ways to reduce the amount of food waste (and thus the related emissions). This interdisciplinary and transdisciplinary project intends to contribute to a better understanding of the role and potential of Peer Supported Processes and local food sharing initiatives in combating food waste and reducing greenhouse gas emissions on an individual household level in a national context.
