During Great Big Green Week 2026, we expect up to two million people - just like you - from across the UK to come Together for Good.

Our theme this year, Together for Good, reflects a simple truth: when people come together in their communities, they create real, practical benefits - for local places, for nature, for climate and for our shared future. From small, everyday actions to bigger community events, Great Big Green Week makes that collective action visible.

The more action that happens locally, the bigger the national impact. Great Big Green Week clearly shows that these aren’t isolated acts; they’re part of a growing movement of collective action for climate and nature.
