There are numerous names for green lodging, including green hotels, ecolodges, and sustainable tourism (conserving both the environment and the culture or social aspects of an area, having a low impact on both). The best place to start your green hotel research is online, starting with the website Environmentally Friendly Hotels, and then using the search engines, where the best term to use is "environmentally friendly hotels". Don't let the various terms confuse you or put you off, because people have different focuses in their environmental actions, and the name often reflects the focus of each specific hotel. The bottom line is the same, though: these properties are interested in preserving their environment, both social and natural.
