Tony records a video message for 10:10

What made you join 10:10?

Some people were attracted to the simple target, the practical advice or the buzz that's surrounded the project since day one. Some used it to build on past successes, while for others, signing up was the first time they really got to grips with their carbon footprint.

And me? I'm involved with 10:10 because it gives me hope.

In 30 years of climate campaigning I've seen my share of highs and lows, but I've never seen anything quite like 10:10. Sure, it's about practical things you can do to cut your carbon, but to me, all those bulbs, boilers and bicycles stand for something bigger.

By being a part of the 10:10 project, you're standing up for optimism, ambition and the idea that we can build something better.

By uniting under the 10:10 banner to tackle climate change, we're saying loud and clear that we won't let it defeat us; that we won't allow the scale of the challenge to drag us into cynicism or hopelessness. By being a part of the 10:10 project, you're standing up for optimism, ambition and the idea that we can work together to build something better, one bright pink step at a time.

Making it happen

From traincationing teens in Croatia (try saying that five times fast), to big-name organisations here in the UK reporting serious savings, it's all starting to come together. In the last couple of weeks, we've heard that the National Library of Scotland cut 18%, UNICEF UK cut 16%, and Natural England's three-year carbon-cutting project cut their emissions in half and saved them nearly £2m a year. And there's plenty more where those came from.

Through projects like My 10:10 and Solar Schools, the next generation of carbon-cutting ideas is taking shape. These won't just help you reduce your own emissions - they'll make it easier to team up with others in your community and throw your weight behind smart policies to speed up our national and international progress.

Taken alone, our individual efforts can feel like drops in the ocean. United under the 10:10 banner, they're snowflakes in an avalanche. As the next phase of this bold experiment takes shape, I'll be staying closely involved – I hope you will too.

Tony Juniper is chair of 10:10's board of directors
