Looking at Fig 2 in the Executive Summary pdf, most of the CO2e emissions for physical shopping is from customer transportation to store - between 50-80% for the various scenarios they considered. For online shopping about 50% of the emissions are from packaging.

The main lessons I see are

- If you drive, then switching to online will reduce emissions by about 30%.

- If you don't drive, and instead bus or walk to shopping stores, then your emissions will be about 10-20% of the car-drivers or online shoppers.
