Provide a pattern for enabling suppliers to use the best information they can for the products they are supplying

Created by: zachzeus

Evidence to support claims in a product passport (or other contracts for sale, etc #43 ) must be available at the time the claims are made. Some types of evidence (e.g. audited/certified records) could be retrospective, and not be available at the point of sale/negotiation, but may be available later in the trade transaction lifecycle. For example; negotiation (prior to transaction), sale (initial transaction), and downstream in the supply chain. Given that different types of evidence are available at different times, how can a buyer use the best information available to set price on ESG values evidenced in the digital supply chain?
