Great Big Green Week is the only mass moment for nature and climate in the UK, and it belongs to everyone. 

Every June, thousands of events take place in towns, cities and villages across the country. From repair cafés and nature walks to community clean-ups and film screenings, people everywhere come together for good and make a real difference.

In 2026, more than 1.6 million people took part across 10,000 events - our biggest year yet. From repair cafes to seed swaps, litter picks to community lunches, communities across the UK showed what it looks like when people come together for good.

Great Big Green Week returns June 5th - 13th 2027. Start thinking about what you could do - whether that's organising something big, joining something local, or simply encouraging a friend to get involved.

Together for good during Great Big Green Week

Save the date: Great Big Green Week is back from 6 to 14 June 2027. Last year's Green Week saw more than 1.6 million people come together across the UK to take action for their communities, for nature and for the climate - and 2027 is our chance to go even further.

Whether you organised an event last time or are getting involved for the first time, now's the moment to start planning. Together, we can keep showing politicians and decision makers that people across the UK want positive change.

Thanks for joining us in 2026

We did it! Together, we made 6–14 June the biggest, boldest, most extraordinary Great Big Green Week yet.

This year, more than 1.6 million people - just like you - came together across 10,000 events to act for and celebrate their communities, taking action for people, climate and nature.

From repair cafés and river blessings to film screenings, seed swaps and snorkel safaris, you showed what it looks like when people across the UK come Together for Good. Together, we sent a powerful message to our decision makers: that people across the UK care deeply about their communities, their natural world and their future - and that they're already building it. 

Great Big Green Week will be back from June 5th - 13th 2027. We hope to see you there. 💚
