Parcel delivery on a warming planet: The efforts and ambitions of six companies, examines practices at Amazon, Deutsche Post DHL Group, FedEx, Flipkart, UPS, and Walmart, focussing on the cost- and energy-intensive “last mile ” of the delivery process. The report also looks at company-wide emissions targets, target dates for full electrification of the delivery vehicle fleets, and presents three case studies, from Delhi, London and Los Angeles), showing how these cities encourage, facilitate, and regulate sustainable last-mile delivery systems. Part of the discussion: the relentless drive to reduce costs and the complexity of subcontracting relations in the last-mile delivery sector which reduces subcontractor abilities to mitigate environmental impacts, for example, by investing in electric vehicles. The report concludes that all six companies demonstrate awareness of their environmental impacts and have set targets to reduce their emissions, but their goals are not sufficiently ambitious or timely. Parcel Delivery on a Warming Planet is published by the Centre for Research on Multinational Corporations (SOMO) in Amsterdam.
