*We measure the output of your website on the basis of three factors. First, there is the so-called "page weight", i.e. the weight of your individual website pages in bytes. The more data that has to be transferred to the visitor, the more energy is required for this. Secondly, we automatically determine the hosting provider of your website and can use the freely available Green Web Foundation database to find out whether their data centers are operated with green electricity or not. And last but not least, there is the number of page views, i.e. the total number of hits your website generates. With these three values, a mass value CO2e (CO2 equivalent) can be approximated quite well, which is used for comparison purposes and to generate visibility. We automatically offset this amount monthly with our partner atmosfair. You can find more information in the Documentation.
