"All ITC's luxury hotels have been accorded the highest rating: LEED Platinum (Leadership in Energy and Environmental Design) making it the 'greenest luxury hotel chain in the world'," the company said in a statement.
The LEED green building rating system is a feature- oriented rating system that awards buildings points for satisfying specified green building criteria.
It takes reviews of six major environmental categories that include sustainable sites, water efficiency, energy and atmosphere, materials and Resources, indoor environmental quality and innovation and design.
"This coveted feat uniquely positions ITC as the first hotel chain in the world to have all its premium luxury hotels accorded the highest rating: LEED Platinum by USGBC," ITC Ltd Executive Director Nakul Anand said.
USGBC President CEO and Founding Chair Rick Fedrizzi said the LEED Platinum rating demonstrates tremendous green building leadership.
The USGBC is a non-profit organisation that focuses on sustainability. Its membership includes corporations, builders, universities, government agencies, and other non- profit organisations.
