Home grocery delivery sounds like a frill for people too lazy to schlep to the store. But having food delivered can be more environmentally friendly than driving to the store, researchers say.
Having groceries delivered can cut carbon dioxide emissions by at least half, compared to driving to the store, according to a new study. That's because the delivery truck offers the equivalent of a "shared ride" for the food.
The electric car may be the next big hope for reducing carbon emissions, but one environmental advocacy group says just how effective these vehicles are at limiting emissions depends on where you are in the country.
