Green Santa is an environmental campaign aimed at educating children on the threats of climate change. Through a series of virals, Dr Maurice Bergs speaks from Santa's compound and reports that due to global climate change, Santa's runway is melting and that he may not be able to take off to deliver his presents. Virals encourage children to visit the site and pledge to save energy. Those children that signed up were sent regular updates on the condition of the runway and received a 'live' broadcast on Christmas Eve to see if they had done enough to save the runway.
