Together for good during Great Big Green Week

Thank you to everyone who took part in Great Big Green Week 2026.

More than 1.6 million people came together from 6 to 14 June to take action for their communities, for nature and for the climate. Together for good, communities across the UK made their neighbourhoods better places to live, protected the natural world they love and showed politicians and decision makers that people across the UK want positive change.

Great Big Green Week returns in June 2027. In the meantime, read more about this year's events, and the reach and impact of the week.

Thanks for joining us in 2025!

We did it! Together, we made 7-15th June the greatest, biggest, greenest week yet.

This year, more than one million people - just like you - acted for, and celebrated with our communities as we took action for people, climate and nature. Together, we have shown that we’re making big swaps, small swaps and , and swaps that change the system, to make our places and spaces better.

We sent an important message, loud and clear, to our decision makers that we care deeply about what’s affecting our communities, and that we need to swap old ways for better ways - now.
