As landmarks and homes across the world switched off their lights, we asked you to spend 60 minutes doing something - anything - positive for our planet.
Just 60 minutes? Yes, just one hour. It may not seem like much, but the magic happens when supporters in over 190 countries and territories - all give an hour for our one home, creating the Biggest Hour for Earth.
In 2023, 414,329 people around the world pledged an hour for earth. That's amazing.

This Hour can shine an unmissable global spotlight on nature loss and climate change, and the need to work together.
- It could compel millions to act, and make millions more take notice.
- It could unite cities, countries, continents, showing what we all have in common, and what we stand to lose.
- It could remind us that time is precious - but that we are powerful - inspiring us to make all other hours count.
