Since the beginning in 2007, Earth Hour has been known for the "lights off"-campaign that engaged people all over the planet. The campaign was originally created both as a symbolic act to support the environment, as well as a way to promote and encourage communities and companies to make environmentally conscious decisions in their daily lives. Earth Hour was created to demonstrate how those millions of decisions can add up together to a major change.
In previous years, lights were even turned off in the Eiffel Tower in Paris, the Sydney Opera House, the ancient Acropolis in Athens as well as Colosseum in Rome.
Since Earth Hours' inception in 2007, the campaign has evolved, and now also consists of alternative and easy (and fun!) suggestions of acts to support the planet. The theme for 2023's Earth Hour is "Invest in Our Planet", which the list of suggested and alternative ways to participate in the campaign clearly shows. Find the list here below.
