Earth Hour is the biggest and most widespread environmental event in history. On March 31, 2012, hundreds of millions of people around the world switched off their lights as part of the campaign to promote awareness and activism to combat climate change. Earth Hour began five years ago as a local Sydney event organized by the World Wildlife Fund (WWF) Australia. Since then, the annual action has expanded its scope through the power of social networking, including the Yammer network that has become the backbone of Earth Hour’s operations.
Earth Hour uses Yammer as an organizing platform that gives its shoestring environmental campaign massive reach. The global network lets a core team of 8 staff members connect with thousands of organizers and hundreds of millions of participants. Yammer has become a one-stop source for sharing files and information – as well as identifying the most effective promotional materials and initiatives so successes can be shared and replicated. Because the network is available from a range of mobile devices, participants can tap into it and share resources wherever and whenever they want.
