A Bold Statement for the Earth

On March 27, 2010 at 8:30 pm, millions of people around the world will come together once again to make a bold statement about their concern about climate change by doing something quite simple—turning off their lights for one hour. Earth Hour symbolizes that by working together, each of us can make a positive impact in the fight against climate change. In the US, it sends a message that Americans care about this issue and stand with the rest of the world in seeking to find solutions to the escalating climate crisis.

Leading the Charge

Earth Hour was first celebrated three years ago in Sydney, Australia, when 2.2 million people and thousands of businesses turned out their lights, allowing the message about climate change to shine brightly.

In March 2009, Earth Hour went global. More than 4100 cities in 87 countries and over 1 billion people around the world turned off their lights for one hour to demonstrate their commitment to slowing the effects of climate change. Last year, 80 million Americans and 318 U.S. cities officially voted for action with their light switch, joining iconic landmarks from around the world that went dark for Earth Hour.
