Measure your Circular Footprint!
The CF focuses entirely on the use of materials in a product and its circular performance. The calculation method is based on both material usage (input side) and post-use processing (output side). The calculation in weight does not take into account the specific flow of material. The circular performance of the input and output side result in a circularity score.
With the CF, the Sustainable Footprint Standard of GSES allows for a pragmatic start for calculating and certifying a circularity score for products. Hence, it fills a gap because there is no standard/calculation method for the circularity of products yet.
The CF method is very accessible, in principle anyone would be able to use the Excel model of the calculation method provided by GSES or the online calculation tool on the GSES platform (BoM calculator) to calculate the CF score. That is because only the flows of materials are included.
