The Great Big Green Week is the UK's biggest ever celebration of community action to tackle climate change and protect nature.
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.
