Earth Hour successfully took place yesterday for another lights off event covering some of the worlds greatest monuments. Participating landmarks included the Sydney Opera House and Harbour Bridge, Tokyo Tower, Taipei 101, The Petronas Towers, Beijing National Stadium (Bird's Nest), Marina Bay Sands Singapore, Gateway of India, The Kremlin and Red Square in Moscow, The Burj Khalifa, The Church of the Nativity (Birthplace of Jesus, Bethlehem), Table Mountain, Dubrovnik City Walls, Eiffel Tower, Avenue Habib Bourguiba, The Acropolis, Tower of Pisa, The Spanish Steps, Brandenburg Gate, Buckingham Palace, Tower Bridge, The UK Houses of Parliament, Big Ben, Christ the Redeemer Statue, CN Tower, Las Vegas Strip, Times Square, The Empire State Building, Niagara Falls and the United Nations Headquarters in New York City. Conceptual artist Yoko Ono lent her support to the event this year.

The event was observed in more than 7000 cities, towns and municipalities in more than 150 countries and territories, with many of the world’s best known human and natural landmarks going dark as the backdrop to a multitude of “beyond the hour” activities and initiatives generating outcomes for the movement and the planet on which we live. “What is most important is the ever increasing extent to which Earth Hour’s supporters are participating in or taking actions themselves,” said Earth Hour CEO and Co-Founder, Andy Ridley. “Now in its 7th year, Earth Hour is maturing from its origins as a consciousness raising event in one city, to a global movement that is not just calling for change but is engaging in it.”

Russian supporters, who last year helped secure legislation against oil pollution in the seas using the I Will If You Will campaign, now have more than 100,000 signatures on a new petition calling for forest protection; while WWF and Earth Hour partners in Madagascar handed out 1000 wood saving stoves to victims of February’s cyclone Haruna, passing significant savings on to families while reducing charcoal producing and wood gathering impacts on forests.

From villages in India without electricity being lit up with solar energy for the first time, to Libya where participants took part in an 80-kilometre walk from Gharyan to the capital Tripoli to celebrate Earth Hour 2013 at 8:30PM - people from all walks of life, all backgrounds went to amazing lengths to share what the planet means to them and what they are willing to do to  protect it.

"In Earth Hour, people around the world, from all walks of life, have come together to express their concern about the planet's wellbeing and to take action," said Jim Leape, Director General of WWF International. "I am inspired to see their commitment. Earth Hour has created a global community, and together we really can make a difference."

Countries across the world have used Earth Hour as a tool to engage children in environmental issues, with Earth Hour organisers the Society of Wilderness (SOW) continuing to run their year-long education program on climate change in schools throughout Taiwan, engaging over 70,000 students and volunteers. Green Schools in Indonesia are also actively engaged in Earth Hour’s beyond the hour campaigns, and Earth Hour was also used to promote the Low Carbon School Network, which incorporates energy-­‐saving lessons in the curricula of Bangkok Metropolitan Authority-­affiliated schools, in Thailand.

Canadian Astronaut Commander Chris Hadfield tweeted images from space in celebration of Earth Hour with his unique perspective of seeing cities and natural wonders from above. Russian Cosmonaut Roman Romanenko also sent a video message from space, before one of the most historic moments in the movement’s history saw The Kremlin, the official residence of the President, and Red Square plunged into darkness for the first time in celebration of last year’s environmental outcome that saw the passing of legislation to protect Russia’s seas from oil pollution.

“The first time I stepped on the board of the International Space Station and saw the Earth from outside, I was amazed by how beautiful and fragile it was.  Our planet is the most precious treasure that we have. It is our home and we fully depend on it. And its existence depends on us as well. It depends on our attitude to it and on how we use its resources,” said Romanenko from the International Space Station.

Six of China’s biggest social media sites with a daily reach of 200 million people also went dark to raise awareness for Earth Hour, and the official Instagram account posted a single image from Sydney’s switch off at the Opera House from their Headquarters in San Francisco that generated more than 180,000 Likes. More than 36,000 Earth Hour images were uploaded to the image sharing platform at the time of this writing.

Anti-apartheid hero Nelson Mandela was one of the first to tweet his support, and ushered a timely message given the many reforestation projects around the world tied to Earth Hour’s I Will If You Will campaign. “The trees & forests were destroyed exactly because our people were so dependent upon them as sources of energy. #NelsonMandela #EarthHour”, he tweeted.

Countries and territories participating in Earth Hour for the first time included Palestine, Suriname, Rwanda and Tunisia; where WWF, the Tunisian National Agency for Energy Management and Tunisian Scouts focused celebrations in Habib Bourguiba Avenue, the birthplace of the Arab Spring. Tunisian President Moncef Marzouki inaugurated the event.  Other celebrities endorsing action for and during Earth Hour included Lionel Messi, ,Amitabh Bachchan, Alejandro Sanz, Imogen Heap and more.
