Welcome to Great Big Green Week 2026, where more than a million people – just like you – will come together to be part of a wave of actions for friends and family, climate and nature.
Together we can all take actions that 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 change 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.
