Following on from Kate's post why not join in yourself? We are looking for more people to take part in this initiative. All you have to do to get started is register, fill in a baseline survey to say what you are already doing and what else you could do (make a few pledges) and start being greener.
Full details of the project are at http://www.greenertogether.coop/
If you are interested, either contact BrightKidz with any questions, or register directly at http://www.greenertogether.coop/user/register .
When you register, please make sure to select "BrightKidz" as the participating organisation.
