10:10 is a movement of more than 100,000 people and organisations taking positive, practical action to tackle climate change.
We inspire and support people in reducing their own carbon footprint, and run projects designed to bring down emissions on a local, national and international level.
You're probably here because you heard about a short promotional film we made in October 2010, entitled No Pressure. The film received an understandably negative reaction, and we quickly realised that we'd made a serious mistake, withdrawing it within hours and apologising to the many people who found it offensive.
You could fill a book with the things we learned from this episode (and the things we changed to make sure it will never happen again), but the most important lesson was 'stick to what you're good at'.
And since then, that's exactly what we've been doing...

When we invited 10:10ers to reduce their carbon by 10% in a year, some people said it was unrealistic. Two years on, some of the UK's biggest organisations have risen to the challenge, cutting thousands of tonnes of carbon and saving millions of pounds on energy. Even the UK government got involved, reducing its own carbon footprint by more than 100,000 tonnes.

On 10 October 2010, we coordinated more than 7,000 carbon-cutting events as part of a global 'Day of Doing' to celebrate the power of practical action.

Our Pitch Pledge Party fundraising experiment brings innovative carbon-cutting projects together with committed donors looking to fund practical climate change solutions at a grassroots level. Our first event, held in October 2011, raised over £15,000 for three projects.
In mid-2011 we launched My 10:10, a blindingly clever website that serves up carbon-cutting advice tailored to your lifestyle. Currently in beta testing, My 10:10 lets you work out your footprint, challenge your friends, earn badges, and share tips with other users.
