Join us for Great Big Green Week 6-14th June 2026
From small, local actions to bigger community events, Great Big Green Week makes visible the collective effort creating real, lasting change. Together for Good.
The Great Big Green Week will take place this year from 6–14 June 2026.
With the theme Together for Good, the week will see people across the country come together in a nationwide celebration of action to protect the planet. From small, everyday actions to bigger community events, Great Big Green Week makes visible the real, practical benefits communities create for local places, for nature, for climate and for our shared future.
The more action that happens locally, the bigger the national impact, showing that these efforts are not isolated, but part of a growing movement of collective action for climate and nature, and underscoring the need for decision‑makers to step up and play their part.
