IUCN is encouraging people across the world to switch off their lights for Earth Hour on March 28.
The initiative, organized by WWF, aims to show governments, individuals and businesses that it is possible to take action on global warming.
"We all need to join this global environmental action to voice our collective concern about climate change and to show world leaders we are serious about securing a Global Deal on climate in less than nine months time," said Julia Marton-Lefèvre, Director General of IUCN.
Earth Hour 2009 aims to reach one billion people in more than 1,000 cities, including businesses, governments and communities. The campaign is expected to produce the largest-ever groundswell of public support.
"Taking the first step is as easy as turning off a light. Encouraging others – entire cities, multinational corporations and people around the world – to perform this simple act for just one hour, makes it possible for everyone to participate," said Julia Marton-Lefèvre. "This is why IUCN is supporting Earth Hour, and is asking all of our members to join us in this important action."
Earth Hour is a broad global coalition campaign led by WWF, and IUCN coordinates closely with the 30 WWF country offices involved, all members of the Union.
Two years ago, Earth Hour began in one city, in one country, when more than 2.2 million households and businesses in Sydney turned off their lights for one hour. Last year, Earth Hour reached 370 cities and towns in more than 35 countries across 18 time zones, and the campaign shifted from a Sydney event to a global sustainability movement.
Earth Hour 2009 will be even bigger because the threats posed by unchecked climate change are escalating, along with people’s concern.
