The Big One

Supported by…

The climate, nature and humanity face disaster. We know it’s time to act. Do you trust politicians to do the right thing for us? For the planet?

Join 100,000 people holding them to account. Tell me more.

Sign up and be counted too…


That’s how many have said they’ll be there.

Will you be there?

The invitation is for everybody to Unite to Survive at ‘The Big One’ – a four day action from the 21st to the 24th April 2023, where people from all groups and movements, not just XR, will gather throughout Westminster and at the Houses of Parliament.

More than 200 organisations are supporting – including Greenpeace, Friends of the Earth and PCS Union to name but a few.

  • Family friendly
  • Accessible and welcoming
  • Creative
  • Engaging

The streets will be transformed with People’s Pickets outside government departments and a diverse programme of speakers, performers and workshops, awash with colour and culture. There will be art and music, talks from experts, places to listen and engage, and activities for the kids. 

  • Friday 21st – Unite to Survive. Westminster is filled with flags, banners and people.
  • Saturday 22nd – Earth Day. An enormous, celebration & family-friendly march for biodiversity!
  • Sunday 23rd – Running Out of Time! The Big One coexists with the London Marathon.
  • Monday 24th – Choose Your Future. Parliament returns, the demand is delivered.

Come on your own, with friends and family, a community group – or a local XR group. Come when you like, leave when you like, and stay for as long as you can. You can always ask a steward (hi viz jackets) to show you around and help you find like minded people. Whatever your plans, come, be heard and be counted!

Not sure you’ll make a difference?

Every single person makes us collectively more powerful, and makes our voices harder for the Government to ignore. Just imagine what thousands of us working together could do. We can make this the biggest climate protest ever held in the UK – something that is talked about for generations. We can bring about change. We can turn the tide. But first, we need to show up.

You are needed, we are needed, everyone is needed.
Here comes everyone.
