Carbon Dioxide Benefits of Using Collection–Delivery Points for Failed Home Deliveries in the United Kingdom

Unlike much of the previous research on this topic, which assesses the economic consequences of failed deliveries to the home, this study examines the issue of failed delivery from a carbon-auditing perspective. It considers the potential environmental savings from the use of alternative forms of collection and delivery over traditional delivery methods for failed home deliveries. With a spreadsheet carbon audit model, carbon dioxide (CO₂) emissions for a failed delivery are calculated on the basis of a typical van home delivery round of 120 drops and 50-mi (80-km) distance. Three first-time delivery failure rates (10%, 30%, and 50%) are assessed. The additional CO₂ from a second delivery attempt increases the emissions per drop by 9% to 75% (depending on the delivery failure rate). The vast majority (85% to 95%) of emissions emanating from a traditional failed delivery arise not from the repeat van delivery but from the personal travel associated with the customer's collecting a missed redelivery from the carrier's local depot. A range of collection–delivery points (CDPs) (supermarkets, post offices, railway stations) were all found to reduce the environmental impact of this personal travel. Post offices (currently operating a CDP system through the U.K. Royal Mail's Local Collect service) yielded the greatest savings, creating just 13% of the CO₂ produced by a traditional collection by car from a local depot. Overall, the research suggests that the use of CDPs offers a convenient and more environmentally friendly alternative to redelivery and customer collection from a local parcel depot.
