Seek out varied modes of (alternative) transportation, including public transit (buses and trains), bicycles, and walking whenever you can. Avoid flying if at all possible, since airplanes consume more gasoline than any other mode of travel. Specify hybrid autos when available from rental agencies – they emit fewer

green-house gases.

Avoid products made from endangered species, hard woods or ancient artifacts. Buy local products in preference to imported goods. Instead of buying typical souvenirs (such as t-shirts that, more than likely, were manufactured thousands of miles from one’s vacation destination), seek out sustainable souvenirs that directly benefit the communities visited (e.g. jewelry made by local artisans).

Respect local cultures, traditions and holy places. A large part of being environmentally-friendly stems from being socially conscious as well. Respect for other cultures and places is of the utmost importance when traveling abroad, but it is also important for localized travel as well.

Use water sparingly. American consumers take the availability of fresh water for granted. In most other countries, clean water is a very precious commodity, and tourists tend to use far more than local people, let alone more than they should. Water conservation should be a natural part of the human existence.

Seek out eco-conscious accommodations. A growing number of lodgings now provide earth-friendly accommodations for their guests. Tell your hotel/motel to change linens/towels weekly, not daily. Patronize those which promote recycling. Seek our earth-friendly cleaners, eco-friendly restaurants, etc.

Keep your carbon footprint in mind. As you consider the energy you use to enjoy time away, consider planting one tree (or more) somewhere to offset your carbon footprint.
