If everyone shopped online and delivery vehicles did all of the delivering, pollution from vehicles would fall dramatically in North America. (But I get what you're saying about your particular location)

Anyways, it's easy to check my assertion via Google Search.

This article is from Stanford University:

"Unless you’re walking or biking to the bookstore, buying a book online results in lower carbon emissions than purchasing it from a traditional bookstore. Light-duty delivery vehicles operated by companies like UPS and FedEx travel well-designed routes that serve multiple consumers in a minimum of trips, achieving fuel economy higher than that of a typical individual consumer driving alone to make the same purchase."
