As Earth Day approaches (Sunday, April 22), online travel site Orbitz is kicking off an eco-tourism microsite at eco.orbitz.com. The site will offer travel tips and articles on top destinations, eco-friendly lodgings and how the tourism industry affects the places all those cruise ships dock and airliners swoop down upon.

For instance, Jason Summer's article, What Is Eco-Tourism, encapsulates the state of eco-tourism today. (By the way, is there a more appropriate name for a travel writer?)

They're not just slapping up a warm and fuzzy website and calling it a day, either.

According to this press release, the company is also walking the walk. Below is a list of the steps Orbitz Worldwide is taking to reduce its environmental impact as part of ongoing business operations.

Recycling efforts:

• Recycling bins in each kitchen for aluminum cans. 95% of the products in our vending machines are cans, not plastic
• Discontinued use of all Styrofoam cups, bowls and plates. Using recyclable paper products
• Distributed to every employee and contractor their own beverage cup and insulated coffee mug to eliminate disposable cups, reducing amount of garbage tremendously, as well as resulting in facility cost savings
• Recycling can at every desk, printer and conference room for paper
• Collection bins in each supply room for batteries

Energy savings:

• Motion sensor lights in offices and conference rooms, turn off when no activity in room
• Lights in entire facility turn off at 10pm, turn on at 7:00am
• High Performance lighting throughout the common seating areas, compliant with the International Energy code
• Water saving filters on kitchen taps
