On 25th March 2023 at 8.30 pm, as landmarks and homes across the world switch off their lights, we are asking you to spend 60 minutes doing something - anything - positive for our planet.

By doing so, this Hour can shine an unmissable global spotlight on nature loss and climate change, and the need to work together to secure a brighter future for people and the planet. 

It could compel millions to act, and make millions more take notice.

It could unite everyone, showing what we all have in common, and what we stand to lose. 

Could an Hour change the world? It’s a start, and it’s up to us.
