Get involved

Be part of the UK’s largest celebration of climate and nature.

Each year, we see thousands of events in towns and cities across the country, showing the power we have when we act for people, climate and nature.

This year was no different: from volunteering with Jersey Trees For Life and a repair café in Anglesey, to OCEAN film screenings in Thurso and a clean up at a community orchard in North Belfast, people everywhere rolled up their sleeves and helped make a difference.

You can be part of this movement in 2026.  Get inspired by what others have achieved and start imagining what you and your community can do next year. Whether it’s a big event or a small action, every step adds up to a greener future.
