Campaign: Plant Spike and Virtual Light Switch

Client: Earth Hour, WWF
WPP company: Wunderman Sydney

Earth Hour is held each year on the last Saturday of March, encouraging households and businesses around the world to turn off their lights for one hour to raise awareness of climate change. A number of WPP companies participate in this global event.

To encourage participation in Earth Hour 2010, Wunderman Sydney created the Plant Spike, which was added to office plant pots around Sydney by plant hire companies. Not only printed on FSC-certified paper, Wunderman partnered with an ink technician to invent a printing ink containing organic plant fertiliser. The spike generated awareness about Earth Hour while providing nutrients to the plants.

Wunderman Sydney also developed a Virtual Light Switch that, when flicked, turns off the lights on your computer screen, and displays information about Earth Hour. The Facebook version of the app was flicked off nearly 32,000 times spreading to over four million Facebook users.

The Plant Spike was awarded a Silver Echo award and the prestigious Echo Green Marketing Award 2010.
