Shop Online, Save the Planet

I do a lot of shopping online. It is by far my preferred means of buying things we don't get on our regular grocery trips to Costco and Supertarget. For a while now, I have been concerned that it was more energy intensive to have UPS trucks driving individual products up to our door. I decided to check it out this afternoon, and it turns out, it uses 35% less energy to buy it online than it does to buy it at a store. Here is the report from Carnegie Mellon:
A new study out of Carnegie Mellon University finds that shopping online instead of going to a retail store cuts CO2 emissions. The research, performed by the university's Green Design Institute, found that shopping online via comparison shopping site Buy.com uses 35 percent less energy consumption and carbon dioxide emissions than what is produced in the traditional retail shopping model....

The three largest contributors to energy consumption and CO2 emissions include customer transport for traditional retail, packaging, and last mile delivery to customer homes for e-commerce. Approximately 65 percent of total emissions generated by the traditional retail model stemmed from the customer getting to and from the retail store. For e-commerce, packaging and last mile delivery were responsible for approximately 22 percent and 32 percent of the ecommerce energy usage, respectively.

Co2 emissions are so low on my list of important issues that I could almost care less, But this article was tapping into a topic that I do enjoy, "efficiency". After doing a quick read on the link I don't think you should be so quick to pat yourself on the back. This study shows only a reduction in Co2 emissions when you shop exclusively with buy.com which drop ships items from the MFG, to the end user skipping a traditional ship in the supply chain, unlike (my estimation) 99% of the on-line retailers. I wasn't able to tell but I would assume this also assumes your only shopping for items available from buy.com. For example I don't think they priced out the saving of buying a flash drive from radio shack and then on the way home picking up bread and milk. So unless I missed something your actually destroying your planet (by your estimation) by shopping on-line. So I think the real lesson here for those concerned with Co2 emissions is "EMIT BABY EMIT".
