Imagine an Hour inspiring millions to act for our planet. An Hour that unites cities, countries, and continents. An Hour reminding us to make all other hours count.

That’s no longer just an hour…that’s the spark we need for change. That’s the #BiggestHourForEarth.

We can make it happen - together. Join us for #EarthHour on 25th March at 8:30 pm local time by switching off and spending 60 minutes doing something - anything - positive for our planet.
