The document discusses how IoT can make imported food supply chains more efficient, cheaper, and environmentally friendly. It explains that IoT allows physical objects to collect and exchange data. This enables monitoring food from farm to fork, improving logistics to reduce carbon emissions from air freight by using ground transport when possible. Sensors along the supply chain could track conditions like temperature to preserve freshness and reduce waste. Connecting the entire supply chain process via an end-to-end IoT system allows optimizing each step for lower costs and greenhouse gas emissions.
