According to an Associated Press book review, the answer is yes.
The book is Lonely Planet’s “Code Green: Experiences of a Lifetime” ($19.95), which
lists 82 trips that have a lesser impact on the environment.
For Americans who may be interested in exploring their own country in an environmentally responsible way, the book outlines several trips that are an interesting take on destinations most of us are already familiar with. If a Maine vacation sounds appealing, consider sailing the coast with the crew of an old-time windjammer. Or take the classic Route 66 road trip, making sure to patronize all the mom-and-pop motels, attractions and diners along the way.

This sort of environmental stance has been long advocated by Route 66 artist and unrepentant hippie Bob Waldmire. At the very least, the lower speeds at which you drive on Route 66 certainly consumes less carbons.
