The Earth Hour is a large-scale collective awareness campaign initiated by WWF in 2007. Every last Saturday in March between 8:30 and 9:30 p.m., Earth Hour celebrates the symbolic “lights off” hour, which has grown from a one city initiative to a mass global event involving more than 172 countries with over 620’000 actions taken to change climate change. The movement is supported by millions of individuals, organisations and governments.
DecarboNet tools have been applied to support the Earth Hour.
The project is also investigating how people get engaged with the campaign on Twitter. As a consortium partner, WWF Switzerland has guided the analysis process and the Earth Hour activities in Switzerland have been especially addressed in this research.
