We dabble in sustainable travel once in a while here at Gadling, but if you really want to get into the science of the process, there are some excellent, well-maintained blogs out on the interwebs. Both Friends of World Heritage and National Geographic’s Intelligent Traveler have dedicated professional staff to keep you informed on the happenings of eco-travel around the planet.
