It ain't easy being green, especially in the middle of NYC. But the Lotte New York Palace does an admirable job. Although it can't plant windmills on its rooftop, it can (and does) offset 100 per cent of its electrical usage through the purchase of renewable energy certificates. This iconic hotel also partners with Clean the World to donate its "gently used" guest room amenities to the global relief organization. A full-time green practices manager is on staff, and the Green Meetings program means that all meeting papers are recycled and food is served in non-plastic containers, among many other efforts. Whether it's the use of high-efficiency lighting or environmentally friendly cleaning products, this property is doing all it can to preserve planet earth. Better yet, your dollars also go towards some good causes, such as feeding and clothing the local homeless.
