With eco-tourism on the rise, eco-hotels are fast becoming the darling of the travel industry. These days, however, staying at an eco-hotel doesn’t necessarily mean vacationing in a tree house in the Costa Rican jungle, although that is certainly a choice.
The majority of eco-hotels fall into one of several categories: hotels and resorts that conserve ecologically important habitats; “green” hotels that reduce, recycle, minimize waste, and protect water; sustainable hotels that harvest food from gardens on the hotel property or get part of all their power from renewable energy; hotels that encourage community involvement such as guests taking part in trail clearing; and hotels that offer some form of environmental education to their guests.
As such, eco-hotels are a various group. Stylish urban hotels like the Willard Inter-Continental Washington focus on energy conservation whereas the Rosario Resort＆Spa on Orcas Island in Washington State offers a wildly popular “green” vacation package where guests can “take a hike, clear a trail”.
No matter what you call them, eco-hotel, eco-lodge, eco-resort, or green hotel, they’re part of the “greening” of the tourism industry.
Part of what drives this greening of the hotel industry is no doubt competition. Going green is yet another way to distinguish a hotel from the mass of other excellent hotels that consumers have to choose from. But for many hotels, it’s also part of their philosophy. With the concept of “going green” firmly rooted in consumers’ minds, eco-hotels have taken it to the next level, and whether or not money is the driving factor behind the greening of the hotel industry doesn’t matter so much as it’s good for the planet.
