According to the results of a new university study, shopping for books, clothes and DVDs online is 24 times more environmentally-friendly than driving to the shops – and seven times greener than hopping on a bus.

Heriot-Watt University researchers compared the carbon footprint of the trip from a typical local delivery depot with the shopping trip by car and also by bus. They found that the home delivery of items resulted in much lower carbon emission levels.

In the research, it was assumed that only one item was purchased during each trip. The focus was on the final stage of the process – that being the delivery of the item to the customer’s home or the customer travelling to the shop to collect the item.

The Logistics Research Centre team at the university learned that in the average van-based home delivery 181g of emissions are produced, as compared with 1,265g during a bus trip and 4,274g when a car is used. What this means is that a shopper would need to purchase 24 items when travelling by car or seven, when making the trip by bus, to match the carbon emissions produced when one item is delivered by van.

The Logistics Research Centre director, Professor Alan McKinnon, and one of the study’s authors, noted that shopping online for single items is even “greener” than venturing out to the shops.
