Come 8.30pm on March 27, 2010, Singapore will turn dark for an hour as hundreds of buildings, shopping malls, national monuments and landmarks island-wide will turn off their non-essential lights during Earth Hour 2010. With the current movement against climate change, organizations and businesses are pledging their support for the energy-saving campaign.

Some of the bigger bodies include Singapore's Changi Airport, who will turn off decorative lights and dimming many operational lights within the terminal buildings and malls, Resorts World Sentosa, and almost all the national monuments and landmark icons, including the Merlion, the Singapore Flyer, Esplanade Theatres, the Fullerton Hotel, One Fullerton, Clifford Pier and the Asian Civilizations Museum.

Around the central business district, the Singapore River will flow in darkness while all around the downtown area, buildings power down for the requisite hour. These include the HSBC Building, Maybank Tower, Raffles City Shopping Mall, One Raffles Quay, Suntec City and Swissotel the Stamford.
