Great Big Green Week 2026 is one of the most powerful opportunities of the year to show your local politicians just how much people care about climate and nature.

In 2025, more than a million people took part in events across the UK. Great Big Green Week is a mainstream public movement, and politicians need to hear about it.

Whether you invite your MP to an event, speak to a local councillor or simply send a message about what you are doing and why it matters, every conversation counts. The more our decision makers hear from the people they represent, the more they will champion these issues.

Here, you will find support to help you come together for good with your community and local politicians from 6 to 14 June 2026, and make your voice heard.
