The document discusses the role of local food in managing carbon in the supply chain. It notes that food production accounts for a significant portion of greenhouse gas emissions and that local food can help reduce emissions through shorter transportation distances and less packaging. While production emissions can vary significantly depending on farming practices, local food may have other benefits like supporting local economies, reconnecting communities with food sources, and increasing food security. The document argues that standardizing emissions data collection and promoting local value chains could help maximize the benefits of local food.
