On Saturday, March 27th at 8:30 p.m. local time, the largest ever public demonstration for action on climate change will take place as lights are symbolically turned off for one hour in homes, office buildings, iconic landmarks, government buildings and retail establishments across the globe for Earth Hour.

Ninety-two countries and regions around the world have now made the pledge for Earth Hour to show the world what can be done to fight climate change. Last year 88 countries got involved in the lights out event.

With confirmation that the Tokyo Tower in Tokyo and Brandenburg Gate in Berlin will both turn off their lights for Earth Hour, all members of the G20 are now taking part in the event.

“Earth Hour is inspiring millions of people all around the world to join together and show their concern for the future of our planet,” said Leslie Aun, WWF’s (World Wildlife Fund) vice president for public relations and the managing director for Earth Hour U.S. 2010. “Here in the U.S., Earth Hour sends a message that Americans are ready to turn out the lights on pollution and climate change and make the switch to energy independence and efficiency.”

The Las Vegas Strip, Mount Rushmore, Sea World, the Empire State Building and the Golden Gate Bridge will join other iconic landmarks from around the world in switching off the lights for Earth Hour. CN Tower in Toronto, Grand Palace in Bangkok, Table Mountain in Cape Town, the London Eye, Hiroshima Peace Memorial and Taipei 101 will plunge into darkness to shed light on dangerous climate change.

Citizens of the United States will unite with individuals, businesses, civil groups and governments around the world including Athens, Bangkok, Cape Town, Delhi, Dubai, Geneva, Hong Kong, Istanbul, Manila, Moscow, Rome, Seoul, Singapore, Sydney, Tel Aviv and Toronto. Communities will come together like never before with cities such as Stockholm and Hiroshima holding their inaugural Earth Hour.

Countries participating in Earth Hour for the first time include: Brunei, Cambodia, Czech Republic, Kosovo, Madagascar, Mauritius, Mongolia, Mozambique, Nepal, Northern Mariana Islands, Oman, Panama, Paraguay, Tanzania, Saudi Arabia, Qatar and the Faroe Islands.
