The commercial continues the campaign idea of ‘together we can all make a difference by illustrating the difference one person can make in just one hour. Our idea was to show the most one person could do for Earth Hour, then ask people to imagine what could be achieved if we all acted together.The commercials shows Cathy Freeman, Olympic Gold Medallist, running a one hour course through Sydney’s CBD, switching lights off in residential houses, flats, pubs, restaurants, hotels, offices, and, incredibly, iconic landmarks like the Sydney Opera House, AMP Tower, and Sydney Harbour Bridge.
