Chain of custody challenges for renewable and recycled materials

Various industries wish to use a mass balance chain of custody to frame claims relating to recycled or renewable content in their products. This approach is based on private certification companies (e.g. ISCC+, REDCert, UL Solutions, etc) and refers to different methodological practices allowing more or less disconnection with the true composition of the product. How can we prevent confusion arising from claims being associated to widely different realities? How direct and relevant should the link between the real recycled or renewable content of a product and the claim made for it be to avoid greenwashing?
