This study determined which transportation option -- farmer delivery or customer pick-up -- consumed less fuel and emitted less CO2 for an Iowa community-supported agriculture (CSA) enterprise. The method used the CSA farmer's actual delivery route(s) including customer addresses, the type of delivery vehicle used, and a hypothetical central pick-up location and time, calculating mileage via Mapquest and fuel/emissions using Bureau of Transportation Statistics and EPA data across four vehicle categories: Ford Ranger, Dodge Caravan, Toyota Prius, and U.S. average passenger vehicle fuel economy. Delivery using a Toyota Prius resulted in 2.77 times lower fuel usage and CO2 emissions than customer pick-up using U.S. average fuel economy; however, even if all CSA customers used a Toyota Prius for pick-up, farmer delivery remained more fuel efficient, though only by a factor of 1.35.
