The 4-Diamond Sheraton on the Falls will be participating in Earth Hour 2011. The hotel joins the attractions, restaurants and shops on the Falls Avenue Resort who will once again take part in dimming lights to mark the event. Signage will be dimmed or turned off, and all non essential, safety related lighting will be switched off from 8:30-9:30pm on Saturday March 26, 2011. Guests will also be encouraged to participate by turning off lights and electronic equipment during the 60 minute campaign which was established to bring awareness to the damage inflicted by climate change. Earth Hour participation is just one of the steps taken by the Sheraton in a move to reduce the carbon footprint of the hotel. The hotel received a 4 Green Key Rating last year from Green Key Eco-Rating Program for initiatives at both the staff and guest levels.
