My goal is to make my webpage (www.MyTree.TV) CO2-neutral! In order to reach this goal I intend to buy CO2-Certificates from www.newTree.org but the problem is that I don't know how to calculate the CO2-emissions of a webpage! The number of users is certainly important but if you consider just the electricity-consumption of a server it's not correct in my opinion. Does anyone know how to make a sound estimation?
