Earth Hour 2007
World Wildlife Fund and the city of Sydney needed to engage citizens in a tangible action against climate change, demonstrating that individual efforts could collectively make a difference. The goal was to create a highly visible, symbolic event to raise awareness and inspire broader participation in environmental conservation.
Creative Idea
One city's symbolic hour of darkness sparked a global movement against climate change.
Earth Hour 2007 transformed a simple act of turning off lights for one hour into a powerful, collective symbol of commitment against climate change, proving that individual actions, when united, could create a significant, measurable impact and spark a global movement.
How The Big Flick Became A Global Blackout
From Despair To Hope
The project was born from a "think tank" at the Sydney Hilton Hotel in 2006, where Andy Ridley and Todd Sampson sought to pivot environmental messaging away from fear - mongering. Originally titled "The Big Flick," the creative team at Leo Burnett famously killed the name because it sounded like a "crappy radio station." The strategy also narrowly avoided a political confrontation; an early draft proposed turning off every light in Sydney except those at Kirribilli House to shame Prime Minister John Howard for his climate inaction. Instead, the team chose an inclusive, "open source" model that allowed the brand to spread without corporate gatekeeping.
The Power Of A Symbolic Hour
On March 31, 2007, the results were immediate and measurable. Over 2.2 million individuals - roughly 56% of Sydney - participated alongside 2,100 businesses, including McDonald’s, which doused its iconic Golden Arches. The event achieved a 10.2% reduction in energy consumption across the city, removing the equivalent of 48,613 cars from the road for one hour. This success was bolstered by high - profile advocates like Cate Blanchett and Lord Mayor Clover Moore, while the cultural momentum of Al Gore’s An Inconvenient Truth provided the perfect zeitgeist for the launch.
Scaling Beyond The Sixty
What began as a local Sydney activation quickly scaled into a global phenomenon, reaching 50 million people across 35 countries by its second year. A key factor in this growth was the involvement of PricewaterhouseCoopers (PwC), the first major sponsor to lend corporate credibility to the radical idea. While the original logo featured a simple "60" for the minutes, it was later updated to "60+" to encourage participants to look beyond the hour.
