Earth Hour is a global initiative that started in 2007 and has since grown into a massive movement that brings together people from all over the world to take a stand against climate change. The event takes place every year on the last Saturday of March, and during this time, people are encouraged to turn off all non-essential lights for an hour, between 8:30 pm and 9:30 pm local time.

Orchard Hotel Singapore (OHS) participated in the Earth Hour 2023 on 25 March 2023. Air condition temperature were turned up and hotel guests and staff were strongly encouraged to switch off lights in the rooms and offices during the hour-long event.

To further spread awareness and mark the hotel’s sustainability efforts and commitment to the movement, OHS offered $0.60, $6 and 60% off deals at Bar Intermezzo and The Orchard Cafe.

The hotel's commitment to sustainability goes beyond just participating in Earth Hour. OHS has implemented various sustainable practices such as increasing the use of reusable material, using energy-efficient lighting, and recycling waste. OHS also has a sustainability committee that focuses on finding new and innovative ways to reduce the hotel’s carbon footprint and protect the environment.
