Feeling guilty about internet shopping? Well don't! A February 2009 study from Scotland's Heriot-Watt University found that the average consumer shopping by car buys fewer than 19 items per trip, shopping on the internet using ground mail delivery will emit less CO2 per item. To even further your eco-friendly choice of internet shopping, choose the US Postal Service for your carrier. They come to your house everyday anyway, they use water-based inks for stamps, a third of all USPS deliveries are made on foot, and its delivery fleet includes electric, hybrid, and biodiesel vehicles.
