New York Marriott Downtown, New York, N.Y.

Marriott has a company-wide policy to cut energy consumption (not just costs) by 25 percent by 2017; they've also debuted “spudware,” biodegradable cutlery made from potato and soy, and turned golf courses into Certified Audubon Cooperative Sanctuaries. So it’s little surprise that this year’s Sustained Excellence award winner from the Environmental Protection Agency went to New York City’s downtown Marriott. Yes, that Marriott in the sweltering asphalt jungle of Manhattan’s Financial District. The 497-room property is also the home of Roy’s, the eclectic Hawaiian-fusion restaurant.
