amb la intenció d'involucrar als australians en el tema del canvi climàtic «FAQS Earth Hour». Earth Hour Media Centre. Arxivat de l'original el 2013-03-17. [Consulta: 21 març 2013]. «Earth Hour came from a think tank initiated by Earth Hour Executive Director and Co-Founder, Andy Ridley, resulting in the formation of a partnership between WWF Australia, Leo Burnett and Fairfax Media to address the climate change issue. In 2007, there was still a degree of scepticism and denial about the issue of climate change. Earth Hour came as the inspiration to rally people to the reality of climate change and start a dialogue about what we as individuals can do to help address the greatest problem facing our planet today. Leo Burnett partnered with WWF to promote the idea and help make the campaign a reality in Sydney, a campaign which has now gone beyond climate change to symbolise the growing global pursuit of a better, healthier world.
