At the end of a long day, it can be more convenient to order
your groceries online while sitting on the living room couch instead of making
a late-night run to the store. New research shows it’s also much more
environmentally friendly to leave the car parked and opt for groceries
delivered to your doorstep.
University of Washington engineers have found that using a
grocery delivery service can cut carbon dioxide emissions by at least half when
compared with individual household trips to the store. Trucks filled to
capacity that deliver to customers clustered in neighborhoods produced the most
savings in carbon dioxide emissions.
