Hospitality Net -- Bethesda, Maryland, USA| In a bold move to help improve the climate, Marriott International, Inc. (NYSE: MAR) is launching a new way for guests to "green" their hotel stays. Now, when you book a room on www.Marriott.com or visit http://www.marriott.com/green-brazilian-rainforest.mi, you can offset the carbon generated during your stay for as little as US$10, or US$1/day for 10 days. As part of Spirit To Preserve, Marriott's five-point environmental strategy, guests can contribute to a Brazilian rainforest preservation fund already supported with a US$2 million commitment by the company.
