Chain of Custody models

ChainPoint supports a range of Chain of Custody models to support all phases of the supply chain’s development towards sustainable sourcing.

Identity Preservation

In this comprehensive Chain of Custody model the physical product can be traced back to its sustainable source. Throughout the supply chain the yield of each identifiable source is kept separate from the products of other sources, even if the latter were produced according to the same standards. At the point of sale consumers can be informed about this unique source (see our Storytelling solutions).

If an aggregated flow of products that was produced according to the same sustainability standard is kept strictly separated from other products as they traverse through the supply chain, we talk about segregation. The products a consumer holds may not be traced back to a single source, but they will be guaranteed 100% sustainable. For most low-interest convenience goods this will be the ideal Chain of Custody model.

For efficiency (but also for environmental reasons) it is not always feasible to segregate sustainable and non-stainable products, especially when there is no physical difference between the two. In the Mass-Balance model products from both sustainable and non-sustainable sources are mixed, but as they move through the supply chain an exact account is kept about the volume ratios. Thus it is guaranteed that the amount of sustainable products produced equals the amount (or volume ratios) of sustainable products sold to consumers.

Book & Claim

In supply chains which may not yet be thoroughly organised, it may not be possible to segregate or carefully account for the volume ratios of sustainable and non-sustainable products. In this case a Book & Claim model can be applied. Where physical products are mixed and traded as non-sustainable, the “right to claim sustainable sourcing” is traded on a separate online market in the form of sustainability certificates. A central authority monitors the sustainability claims by brands and retailers and compares these with the amount of certificates issued and traded. This is also a useful model for markets where the local demand for sustainable products exceeds the local supply.
