Earth Hour 2026 commemorates its twentieth anniversary as one of the most influential environmental movements globally, inviting a symbolic blackout on March 28 at 8:30 PM, which will extend across more than 190 nations.
In these times of international uncertainty, WWF emphasizes the importance of collective action by recalling 20 outstanding achievements in the environmental field over these two decades.
What began as a local initiative in Sydney has evolved into a worldwide event.
Currently, more than 190 countries and territories participate, and iconic places like the Eiffel Tower and the Empire State Building turn off their lights to highlight the urgency of climate change.
This movement has been a symbol of the power of collective action. Every year, communities, schools, businesses, and governments unite through educational activities, sustainable challenges, and concrete commitments to minimize their environmental impact.
WWF highlights the progress made in climate matters over 20 years, calling for a global blackout on the upcoming March 28.
Since its inception in 2006 as a symbolic blackout in Sydney, the event has transcended into a global phenomenon.
Earth Hour 2026 celebrates 20 years of mobilizing millions of people, who turn off the lights for an hour to demonstrate that collective action can trigger significant political and economic changes.
On March 28, from 8:30 to 9:30 PM, once again, iconic monuments from more than 190 countries will join the movement.
WWF highlights this anniversary by emphasizing 20 notable advances in climate and biodiversity, including the 50% reduction in emissions in regulated sectors of the European market since 2005 and the increase in companies adopting Net Zero targets.
In the field of conservation, the Iberian lynx has experienced a remarkable increase, going from 100 specimens to more than 2,400 in just over two decades.
Improvements are also observed in the populations of imperial eagles, wolves, bears, whales, and sea turtles. Spain leads in marine protection, with almost 25% of its maritime surface under protection.
Juan Carlos del Olmo, Secretary General of WWF Spain, emphasizes that humanity can improve its relationship with nature by listening to science. In a context of climate crises, fires, and extreme phenomena, the campaign seeks to convey a message of hope.
Previous editions have featured the participation of icons like the Eiffel Tower, the Colosseum, and the Sydney Opera House. This year, historic buildings, businesses, and homes worldwide are expected to join again.
Earth Hour reminds us that one hour of blackout can drive lasting change
On its twentieth anniversary, Earth Hour not only celebrates its achievements but also looks to the future. Faced with global challenges such as the climate crisis and biodiversity loss, the movement invites everyone to continue acting, demonstrating that one hour can ignite a change that persists.
