How are you working towards making your school Carbon Neutral

We keep stressing that our kids need to be digital natives which I totally agree with but we also need to ask ourselves what are we doing at schools to promote sustaninability to ensure they have a planet worth living on. Funnily enough technology and environmentalism are very intertwined. Here is what I am doing at my school but I would love to hear what others are doing to ensure a greener future for our students.
