10:10 inspires and supports people and organisations to cut their carbon emissions by 10% in a year.
Any individual, family, business or organisation can make the cuts - and by working together we can make a real difference.
If your country doesn't appear on the list on the right of this page, you can still sign up. Just enter your details using the Join Us form on the left. People, businesses, schools, organisations from anywhere in the world can join 10:10.
We're no longer accepting applications to start new national 10:10 projects. However, we're always looking for volunteers and organisations to support 10:10 and help spread the word about the campaign in new countries. There are a variety of different tools and materials available on our resources page which you can use to get started.
If you have been working to cut carbon in your country or have been involved in spreading the 10:10 message to a wider audience, why not write us a guest blog? Check out our guide for guest contributors, then get writing. When you're finished, send it to us at email@example.com.
