Greenify the shopping experience: Real Costs

May 11, 2007

RealCosts is “is a Firefox plug-in that inserts emissions data into travel related e-commerce websites. The first version adds CO2 emissions information to airfare websites such as,,, etc. Following versions will work with car directions, car rental, and shipping websites. Think of it like the nutritional information labeling on the back of food… except for emissions“.

This kind of service was already available on some e-commerce websites (for instance on french website). But what I like in Real Costs:

I really feel this kind of service should be integrated in shopping engines – to expose those environmental considerations to a bigger audience.
