Your involvement will put the ‘great’ in Great Big Green Week. We have plenty of resources to help you every step of the way.
Whether you are interested in having a more effective conversation about climate change, or want to organise a local green week event to swap together for good, whatever you need you’ll be able to find it on this page.
Welcome to Great Big Green Week 2025, when a million people – just like you – will come together to be part of a wave of actions for friends and family, climate and nature.
We can all make small swaps, large swaps and swaps that change the system, to make our communities better.
By coming together, we’ll also send a message loud and clear to our politicians and decision makers that we need to swap old ways for better ways now.
Great Big Green Week is the UK’s biggest celebration of community action to tackle climate change and protect nature.
During the week, communities, schools, businesses, churches, mosques and more join together in a wave of support for action to protect the planet.
