When is the carbon footprint of online shopping less than that of driving to the store?

The carbon footprint of online shopping may be less than driving to the store when the online order is shipped along with other packages on a delivery truck that were already scheduled to be in the area, or when the online order is shipped from a warehouse that is closer to the customer's location than the nearest brick-and-mortar store. Other factors that can impact the carbon footprint include the distance the customer would have to drive to the store, the mode of transportation used, and the efficiency of the delivery and shipping methods. It is difficult to pinpoint a specific scenario, as it can vary depending on the specific situation.
