But one green habit might be as easy as skipping next Sunday’s grocery trip. A study published in the Journal of the Transportation Research Forum reveals that grocery delivery is easier not only on you, but on the planet, too. Using Seattle as a model, engineers at the University of Washington found that delivery service trucks generated 20 to 75 percent less carbon dioxide than personal vehicles driven to and from the grocery store.
While zero emissions are ideal, grocery delivery offers a conveniently green option for those who don't live walking or biking distance from a store.
It turns out that delivery services also help grocery companies green their wallets. Goodchild and study lead author Ericka Wygonik, a Ph.D. candidate in civil and environmental engineering at the University of Washington, observed that delivery service providers produced up to 90 percent less carbon dioxide if they used routes that delivered to groups of residences, rather than individual households at separate delivery times.
