Great Big Green Week

The Great Big Green Week, which will take place between 18 – 26 September 2021, is described as the largest event for climate and nature ever seen in the UK. Local and national events will celebrate how communities are taking action to tackle climate change and protect green spaces and encourage others to get involved too. 

You can find the full list of events on the Great Big Green Week website.
