The Great Big Green Week, running from 24 September to 2 October, is the biggest celebration in the UK of community action to tackle climate change and protect nature. In collaboration with @theclimatecoalition, we want to make this the greatest, greenest week yet - and you’re invited to join us. Whether you're planting trees or making positive lifestyle changes, there are lots of ways to join in and make a difference. We'd love to hear your great green ideas - let us know in the comments below. #NationalTrust
