If you've thought about staying in "eco-friendly" hotels, you're not alone.
The most recent report on the subject, conducted in 2009 by travel research firm PhoCusWright, found that more than 40 percent of 1,334 U.S. travelers surveyed said they considered environmental impact important when planning travel.
Still, finding an environmentally friendly hotel isn't easy, although there are shifts in the hotel industry.
Glenn Hasek, editor and publisher of Green Lodging News, points to inspiring initiatives: hotels with a windmill or solar power, an embryonic hotel chain with plans for "revolutionary new environmental practices and sustainability principles," a rising number of LEED-rated hotels and more focus by the industry as the economy improves.
A common problem for consumers, though, is distinguishing window dressing from serious commitment. Some practices touted as "green" -- admonitions to re-use towels, save water, turn off the lights or skip the room makeup, for example -- are also overtly self-serving: They're cheaper for the hotel. Others, such as recycling, providing windows that open or installing some solar panels, are trivial unless they are part of a comprehensive program.
All that green noise not only bestows unearned merit on the underwhelming, but also makes it harder to discern genuine efforts. The PhoCusWright survey found that 56 percent of people are skeptical of companies that tout green practices.
The American Hotel & Lodging Association, which represents U.S. hoteliers, offers green guidelines to its members but no certification, said Patrick Maher, a member who acts as the group's "green guru." His 2020 vision is that more of the country's 5 million guest rooms will be in zero-waste buildings that are off the power grid.
There is no shortage of green certifiers. Given the consumer interest, the U.S. travel market is a-sprout with rating systems: green hearts and coronets, checkmarks, arrows, suitcases, stars and planets, trees, keys and leaves. The problem is that some are for-profit while others rely on self-reporting, with no site visits to verify the claims.
