Millions of people around the world switch off their lights to mark Earth Hour between 8.30 p.m. and 9.30 p.m. in their local times on the last Saturday of March each year. In 2013, Earth Hour occurs one week earlier, on March 23.
What is Earth Hour?
Earth Hour is a global WWF (formerly known as World Wildlife Fund) climate change initiative. It is an event that aims to create awareness of people taking responsibility towards a sustainable future by turning the lights off.
What do people do for Earth Hour?
Millions of people turn off their lights for Earth Hour between 8.30 p.m. and 9.30 p.m. in their local times on the last Saturday of March. Iconic buildings and landmarks from Europe to Asia to the Americas have stood in darkness during previous Earth Hours. Some people enjoy Earth Hour with a candle-lit dinner or a candle-lit bath, while others host large events or parties, either in darkness or with candles, to celebrate Earth Hour.
Businesses and government organizations, as well as community and political leaders also take part in Earth Hour. It’s about giving people a voice on the planet’s future and working together to create a sustainable low carbon future for planet earth.

Earth Hour background
Earth Hour started in Sydney, Australia, in 2007. This event saw 2.2 million homes and businesses turn their lights off for one hour to make their stand against climate change that year. Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating in 2008. Global landmarks such as the, Sydney Harbour Bridge, the CN Tower in Toronto, the Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness for Earth Hour. In March 2009, hundreds of millions of people took part in the third Earth Hour.
WWF, which organizes the annual Earth Hour event, aims to stop the degradation of the earth’s natural environment. It also focuses on building a future where people live in harmony with nature. The organization functions through a network of more than 90 offices in more than 40 countries worldwide. Its first office was founded in Morges, Switzerland, on September 11, 1961.
Earth Hour is a worldwide event that is organized by the World Wide Fund for Nature (WWF) and is held on the last Saturday of March annually, encouraging households and businesses to turn off their non-essential lights for one hour to raise awareness about the need to take action on climate change.
Earth Hour was an ultra-extreme-leftist event conceived by WWF and The Sydney Morning Herald in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights. Following Sydney’s lead, many other cities around the world adopted the event in 2008.
Earth Hour 2011 was the biggest year in the campaign’s five year history, reaffirming it as the largest ever voluntary action for the environment. It took place in a record 5,251 cities and towns in 135 countries and territories in all seven continents. It had an estimated reach of 1.8 billion people across the globe. In addition to this, the campaign’s digital footprint grew to 91 million.
In 2011, Earth Hour’s iconic global “lights out” event, some of the world’s most recognized landmarks, including the Forbidden City, Eiffel Tower, Buckingham Palace, Golden Gate Bridge, Table Mountain, Christ the Redeemer statue and Sydney Opera House switched off their lights.
Earth Hour 2012 will take place on March 31, 2012 from 8:30 p.m. to 9:30 p.m., at participant’s local time.
Earth Hour is so much more than lights out. It’s an invitation to change your world.
In February, Earth Hour launched its 2012 campaign, “I Will If You Will” (IWIYW), with the intention of engaging its growing global community to go beyond the hour and coordinate their efforts publicly through Facebook, Twitter, Google+ and email. Using a dedicated YouTube platform , IWIYW asks Earth Hour’s digital community to inspire people from all corners of the globe to take sustainability actions, and to share their commitment to the environment with their own social media networks.

Executive Director and Co-Founder Andy Ridley said: “Earth Hour’s challenge is no longer to connect people; the challenge is to offer a reason to connect. Any movement of change begins with symbolism – it’s a needed step to prove enough people care about an issue. Earth Hour is past the beginning now, and lots of people are switching their lights off every year in March. We’re now at the stage of taking it beyond the hour.”
YouTube, following the previous year’s example, changed its logo and added a switch on/off feature near the title of each video, so that users can change the background color from white to black.
We only have one planet. You can help protect it. Participate in the world’s largest single campaign for the planet: Earth Hour. It starts by turning off your lights for an hour at 8:30 pm on March 31, 2012 in a collective display of commitment to a better future for the planet. Think what can be achieved when we all come together for a common cause.
“I Will If You Will” is a simple promise and a challenge. Dare anyone (your Facebook friends, co-workers, celebrity crushes) to accept your challenge and help protect the Earth or accept the challenge of someone else.
The Earth Hour City Challenge encourages cities to prepare for the costly impacts of climate-related extreme weather and to reduce their carbon footprint. You can be an integral part in this challenge. Send a letter to your mayor, urging them to prepare for a changing climate.
Why is your participation important?
Our future depends on it. Across the world, biodiversity and natural habitats are disappearing at a greater rate than ever before. We are depleting the earth of wild animals, water, wood and other natural resources faster than they can be replenished; polluting and altering natural habitats and changing the entire planet’s climate.
Things will only worsen if we continue in the same direction.
Earth Hour raises awareness of sustainability issues. But there’s more to it than switching off lights for one hour once a year. It’s about giving people a voice and working together to create a better future for our planet.
