Soneva Fushi Resort & Six Senses Spa
Most of its reef-rimmed islands rise fewer than three feet above the ocean, which makes the Maldives particularly vulnerable to climate change. No surprise, then, that Soneva Fushi, a collection of refined, castaway-style villas, has pledged to cut its greenhouse gas emissions in half by next year and achieve carbon neutrality by 2010. To meet this goal, it's capturing waste heat from power generators, encouraging guests to offset the emissions of their (long) flights, and transitioning to renewable energy sources. The big news this year: a deep-sea air-conditioning system that circulates cold water pumped up from 985 feet under the sea.
