The newest addition to the Galapagos Island is almost as natural as the archipelago's inhabitants. The area's new airport itself is made up of 80 percent recycled material and hosts its own desalination system for providing water to the terminals. All of the airport's other functions are fueled by wind and solar power.

The airport has done such a good job keeping sustainability the leading factor in this design that the building received a gold certificate from the US Green Building Council's Leadership in Energy and Environmental Design. This travel hub is the first of its kind, winning the title of world's first green airport.
