Earth Hour 2017

We’ve teamed up with World Wide Fund for Nature (WWF) again to mark Earth Hour and show that O2 is committed to helping tackle climate change. On Saturday 25 March 2017 from 8:30pm-9:30pm, you can join millions of people across the UK and the world and switch off your lights for an hour.

In previous years, famous landmarks from across the world, such as Big Ben, the Eiffel Tower, the Empire State Building, and even Sydney Opera House have joined the switch off. And of course, we’ll be showing out support at O2.

So join us, and switch off your lights in a symbolic show of global support to protect the planet at 8.30pm on Saturday 25 March. Sign up, switch off your lights and show you want action on climate change.

But that’s not all. As part of O2’s Blueprint, we are committed to protecting our planet in a number of other ways too. We’re continuing to reduce the impact of our network, and providing solutions such as O2 Home and O2 Drive to allow our customers to monitor and reduce their own impact. We are also giving our customers the choice to make informed environmental decisions with initiatives such as Eco Rating, and O2 Recycle. And we’re supporting young people’s great ideas on how to use technoligy to help the planet. Anyone aged between 17 and 24, can apply for up to £10,000 from The Environment Now programme via

If you think you’ll forget, join the Earth Hour text alert service and you’ll receive a reminder an hour before Earth Hour begins so you can get ready to switch the lights off!  Simply text EARTHHOUR, EARTH or EARTHOUR to 61202. The text reminder service is for people on ANY network, not just O2 customers. Please note, the standard network charge for a text will apply.
