UN Secretary General's Message for Earth Hour

Earth Hour began as a simple gesture.

Now it is a global signal: people everywhere are calling for climate action.

This year, as Earth Hour marks 20 years of impact, I invite you to join the millions who are turning off non-essential lights on Saturday, 28 March, from 8.30 to 9.30 p.m.

But let it be more than a shot in the dark.

Let it be a spark for change.

Demand faster emissions cuts;

A rapid and just transition from fossil fuels to renewables;

And real support for communities already facing the worst impacts.

Speak up. Mobilize.

Help power a safer, fairer future for all.
