The Little Nell sits at the foot of the Rocky Mountains and is the only five-star property in the United States to be ISO 14001 certified, an environmental management standard.
Over the years, The Little Nell has changed its practices and installed equipment to conserve the environment. The lighting is fully energy efficient, the hotel has several solar panels and most of the food is sourced from local producers. The property started an innovative program called the Eco-Luxe Program that gets its customers involved in the effort with actions like offering them reusable water pitchers. The Little Nell also funds the Environment Foundation that backs projects aiming to reduce the impacts of climate change.
