Earth Hour, created by the World Wildlife Fund (WWF), invites people to switch off their lights for one hour to show support for protecting our planet and stopping climate change. Columbia Facilities and Operations will shut off non-essential campus lights from 8:30 p.m. to 9:30 p.m. on Saturday to honor the event, which aligns with the University’s Sustainability Plan and the Sustainable Columbia movement.

Last year, Columbia joined a coalition of more than 2,500 leaders across America’s state houses, city halls, board rooms, faith organizations, and college campuses to affirm their commitment to address climate change.

Starting as a symbolic lights-out event in Sydney in 2007, WWF’s Earth Hour has grown to become the world's largest grassroots movement for the environment, inspiring more than a million individuals to take tangible climate action for over a decade. Different countries are organizing events according to environmental issues that they feel are most relevant to them. Visit to see what’s happening in locations around the world.

Everyone can join Earth Hour by turning off all non-essential lights at 8:30 p.m. in their local time zone and recommitting to the fight against climate change.
