How to take part in Earth Hour

Switch off at home – join millions and switch off your lights at 8:30pm for one hour on Saturday 27th March.

Download the My Footprint app and take on a challenge for our planet, joining a community of people doing their bit for our planet. You could even challenge your friends and family.

Show your support on social media and share what you’re doing to reduce your footprint, with #EarthHourUK 

Bring your community together online. And stay tuned for some online events for Earth Hour you can join

Joining Earth Hour from home

  • Switch off your lights – switch off non-essential lights to show you care for the future of the planet.
  • Join an online event – WWF will be hosting live events on the night and sharing community events that are taking place near you.
  • Music to your ears – light a candle, put your phone on ‘do not disturb’ and listen to the #EarthHour Spotify playlist.
  • Nature Walk – go for a night-time walk and see what you can spot. Do some research into local wildlife so you know where best to walk and what nocturnal animals to look out for.
  •  Starry sky gazing – if it’s a clear evening you could spend your Earth Hour stargazing. There are lots of apps that show you how to find stars and constellations.

However you choose to spend the hour, you can find tips at and share your plans with WWF on social media using #EarthHourUK.
