2G3S (Green Groups in the Shelfords, Stapleford and Sawston) aims to promote a positive vision of a society that enhances, rather than degrades, the natural environment on which we all depend. We hold events in our constituent villages and spread information to raise awareness of green issues and to show how we can work together, both at an individual and at an organisational level, to make changes to our way of life that will lead to a more stable and sustainable future.
