I watch a show on BBCAmerica called Top Gear. It's a car show and it's hilarious. One of the hosts is anti-green and set out to prove how "not green" the Prius was. He pointed out that while the car itself may be gas-efficient and have low emissions the components of the car, battery and internal workings aren't green AND have to be shipped all over the world which is also not green. Ever since then I've considered shipping in my decision on green products.
When I decided to switch to the Diva Cup I drove to a store outside of my usual area in my gas-efficient Ford Focus to buy it rather than ordering it online. Similarly I'm trying to decide now between making my own laundry detergent and ordering Eco-Nuts online. I have some hair products that I'd love to make, but all the recipes I have call for pure Shea butter. I haven't found anywhere local to buy that, but I'm not sure which is greener: ordering Shea butter online and making natural products, or buying a mostly natural product in the store that was shipped already.
Have you made any green decisions based on or influenced by shipping concerns?
