Whether you want to play scrabble by candlelight, have a dinner party for friends, go for an exhilarating night cycle-ride or go along to one of the Earth Hour events happening across the country, you’ll be an important part of WWF’s global event…

Sign up and switch off

At 8:30 pm on Saturday 31 March 2012 switch off all non-essential lights and be a part of something HUGE. Connect with 1.8billion people around the world. Once signed up you can share your plans for the night on our UK event map.

Spread the word

Why not send our lovely Earth Hour eCards to everyone you know to let them know about this phenomenal event? Get a badge for your twitter profile to show you’ll be taking part and encourage your friends to do the same.

Plan a night to remember

Celebrate our brilliant world, by getting together with friends and family! Get some inspiration from our candle-lit dinner party menus from celebrity chefs and our brilliant dinner party guide download. There’s loads of other things you can do in the dark, just have a look.

See what others are doing

Take a look at what other individuals, businesses and even some of the nation’s best known landmarks are planning for Earth Hour. Rumour has it someone is having an Earth Hour wedding! You can plan something amazing and join our Community Competition to lead the switch off!

Beyond the hour…

WWF’s Earth Hour is not about an hour of darkness. It’s about a brighter future for our planet. And that goes beyond the hour to the way we live our lives – year around. Start to reduce your impact by reducing your energy consumption, recycling, cooking your own food and so much more. Have a look at some practical tips here.

Help save 1 billion trees in the Amazon Rainforest

As well as turning off your lights for an hour to show you care about our brilliant planet, you can support our work to help protect it.

For the second year, money raised through Earth Hour will help to protect the Amazon rainforest with Sky Rainforest Rescue.
