This document summarizes research from the U.S. Travel Association on consumers' environmental consciousness and behaviors related to travel. Some key findings include: - 79% of U.S. adults consider themselves environmentally conscious, and this increases with age. Major gains have been seen between 2007-2009 in green behaviors like recycling and using efficient light bulbs. - Familiarity with concepts like "green tourism" and "carbon footprint" has increased impressively, though purchase of carbon offsets still lags. - Those most aware of green concepts tend to be men, older, well-educated, and active/upscale travelers. One-third are influenced by a travel supplier's environmental responsibility.
