Home deliveries of fresh produce may be better for the environment than shopping locally, according to new research by the University of Exeter.
Researchers compared carbon emissions generated from trips to a farm shop with deliveries of organic vegetable boxes. They found that if the average car journey was a round trip of around four miles (6.4km) or more, home delivery accounted for fewer emissions, even if the farm shop used no lighting, heating or chilling.
Researcher David Coley said that while food miles had been useful to get people to think about the issues around carbon emissions and food transport, the many factors that lie behind putting food on the table needed to be looked at "before we can say what is better or worse for the environment".
