What Is The Great Big Green Week?

The Great Big Green Week is the UK’s biggest ever celebration of community action to tackle climate change and protect nature. 

Every year, people come together to unleash a wave of support for action to protect the planet. Tens of thousands of people in every corner of the country celebrate the heartfelt, brave, everyday actions being taken to stand up for nature and fight climate change.

In 2023, Great Big Green Week will take place between 10th and 18th June.

What Sort Of Events Take Place?

Great Big Green Week sees everything from litter picks to letter writing, festivals to football matches, seaweed foraging to school assemblies.

Events are hosted by teachers, bus drivers, sport clubs, artists, community groups, places of worship, libraries, builders – anyone who cares about climate change.

Local Green Weeks – Great Big Green Week community hubs – celebrate local activity, raise the profile of climate change and show why it is relevant to the community and local decision makers.

What's happened so far?

The first Great Big Green Week took place in September 2021, and was the largest event for climate and nature ever seen in the UK.  Over 5,000 events celebrated how communities are taking action to tackle climate change and protect green spaces, and encouraged others to get involved too.

Communities came together once more in September 2022 to show how people everywhere are ready and willing to take action to tackle climate change. Over a quarter of a million people got involved, and national organisations, institutions, businesses and media outlets joined in, ultimately putting pressure on the government to up its game on climate change.

Why now?

In the UK and abroad, we’re seeing the impacts of floods, fires and storms alongside spiralling costs of living.

We have hope because the solutions already exist. We need to cut cut emissions and move towards cheaper and cleaner renewables. We need to protect nature and wildlife, restoring them to their former, healthy glory. And we must play our part overseas to support and protect people from the worst effects of climate change. 

People everywhere are stepping up to take part in Great Big Green Week to show their support for a safer, greener future. Now we need the government to follow suit and take rapid action to tackle climate change, protect nature and bring down bills.
