Check out the Circular Footprint, Environmental Footprint & Health Footprint standards of the GSES System for measuring Products and Projects.
The Circular Footprint (CF) is part of the product certification standard of the GSES System – Sustainable Footprint Standard. Next to the Circular Footprint, the Sustainable Footprint Standard consists of the Environmental Footprint (EF) and the Health Footprint (HF). The three topics (CF, EF, and HF) give a comprehensive picture of the sustainability performance of a product, the production process, and the supply chain.
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.
