Aware of all the impacts humans have on nature - its resources that we often take for granted, yet cannot withstand our demands without consequences - and its possibilities, WWF has been warning for decades that our behavior must change.

However, we are not here just to warn and present scientific evidence supporting the serious disruption in nature's balance. WWF also offers concrete solutions on how to restore that balance.

Apart from inviting all cities in our region to join Earth Hour by switching off the lights that illuminate the most recognizable monuments in capitals, cities, and places, we have joined forces again with the Zagreb Tourism Board for their Festival of Lights Zagreb. Take a look how it looked like last year! 

This year, the video that will illuminate the State Archives building in Zagreb will focus on the power of water. Notably, Earth Hour coincides with World Water Day.

Join us in Zagreb on Saturday, March 22, at 20:30 and enjoy the wonderful spectacle of light on Marulic Square. If you're not in Zagreb, wherever you are in our region, switch off your lights for Earth Hour and switch on the light in your head. Light up all the ideas on how you, and all of us, can behave better to sustain life on Earth.

Since our beginnings, Earth Hour has been known for the symbolic “lights off” in support of our planet. But starting 2023, we've stepped things up, breathing new life into our movement and mission to create the Biggest Hour for Earth. 

Whether you’re into food, fitness, the arts, or the outdoors, anyone, anywhere can give an hour to care for our planet. Last year, the world gave more than 1.4 million hours. This year, let us unite and go beyond to create the Biggest Hour For Earth!
