THE Earth Hour movement - a global initiative led by the World Wide Fund for Nature - will relocate its global headquarters from Sydney to Singapore, and it will officially open here in May.
This makes Earth Hour the first worldwide grassroots campaign to base its operations here.
The annual Earth Hour campaign urges households and businesses to turn off their lights for one hour.
There are about 130 international non-governmental organisations (NGOs) with offices here, of which four focus on environmental and conservation work, said the Economic Development Board (EDB).
The EDB set up a programme in 2007 to provide support for NGOs interested to set up here.
Earth Hour co-founder Andy Ridly said Singapore offers "a level of connectivity and opportunity that the campaign needs and desires moving forward".
