ABOUT
What Is The Great Big Green Week?
The Great Big Green Week is the UK’s biggest ever celebration of community action to tackle climate change and protect nature.
Every year, people come together to unleash a wave of support for action to protect the planet. Tens of thousands of people in every corner of the country celebrate the heartfelt, brave, everyday actions being taken to stand up for nature and fight climate change.
In 2025, Great Big Green Week will take place between 7th and 15th June.
What Sort Of Events Take Place?
Great Big Green Week sees all kinds of events take place – from clothes or book swaps, to skill swaps in allotments or upcycling workshops, to knowledge swaps on discussion panels or wildlife reserves.
Events are hosted by teachers, bus drivers, sport clubs, artists, community groups, places of worship, libraries, builders – anyone who cares about climate change.
Local Green Weeks – Great Big Green Week community hubs – celebrate local activity, raise the profile of climate change and show why it is relevant to the community and local decision makers.
What's happened so far?
The first Great Big Green Week took place in September 2021, and was the largest event for climate and nature ever seen in the UK.
Every year since, we’ve come together in our communities, in schools, in places of worship and in businesses, putting pressure on politicians to up their game on climate change.

What can I do?
Host events and activities in your local area from 7th to 15th June 2025, and make this the greatest, biggest, greenest week of the year.
Your event or Local Green Week will celebrate how your community is taking action to tackle climate change and protect green spaces, and encourage others to get involved too.
Why now?
By taking action together at the same time in every corner of the country, politicians will be unable to ignore that their constituents care about tackling climate change and protecting nature.
Collectively, we will show decision makers there is a public mandate for policies that create a cleaner, greener, fairer future. The solutions already exist: we need to protect and restore nature in the UK and abroad, swap polluting fossil fuels for affordable renewables, and support those hit hardest by climate change around the world. And these same solutions will help tackle the cost of living crisis and create a safer, stronger economy.
We need to get back on track to a world that works for everyone. Let’s swap together, for good.
