This year, thousands of individuals and organisations across many countries are putting aside their differences to help write the first chapter of 21st Century’s biggest story

The idea is simple: we work together to achieve a 10% cut in the UK’s carbon emissions in 2010. From village post offices to City skyscrapers, everyone’s invited.

Cutting 10% in one year is a bold target, but for most of us it’s an achievable one, and is in line with what scientists say we need right now. And by signing up to a 10% target we’re not just supporting 10:10 - we’re making it happen.

The success of 10:10 depends on getting everyone involved, and the 10:10 website has all the tools you need to pass the message on far and wide. We need to start spreading the word to every corner of the country, inviting our friends, family, colleagues, customers, competitors – everyone we know – to take part.

It’s easy to feel powerless in the face of a huge problem like climate change, but by uniting large numbers of people and institutions around immediate, effective and achievable action, 10:10 enables all of us to make a meaningful difference. It’s the perfect opportunity to find out what’s possible when we work together. 10:10 is about putting aside our differences to tackle the defining challenge of our age. 10:10 is about working together and raising our game. 10:10 is an idea whose time has come. Let’s get started.
