Digital Product Identities
The mechanism that gives physical-outcome taxation and lifecycle accountability something real to act on, with verification built in.
Digital product identities
This is the mechanism that makes physical-outcome taxation and lifecycle accountability practically implementable, rather than a nice equation with no way to populate its inputs.
A product entering the economy can carry a digital product identity: a machine-readable record containing, or providing controlled access to, verified attributes such as:
- manufacturer, model and product category;
- constituent materials and recycled content;
- embodied energy and expected energy consumption in use;
- repairability and spare-parts availability;
- expected lifetime and durability;
- hazardous substances and disassembly information;
- the intended recycling / recovery pathway;
- conformity documentation and safety certifications.
Exact requirements would differ by product category — a toaster does not need the same information architecture as an electric vehicle. The principle is that a physical product should increasingly carry a machine-readable description of what it actually is, usable across its whole life:
That single identity is designed to interface with systems that today largely operate as disconnected paperwork describing the same object: product standards, product safety, taxation, customs, consumer information, trading standards, repair and resale markets, and recycling.
This does not mean self-certification is trusted at face value. A manufacturer declaring 80% recycled content, a 15-year expected lifetime or high repairability needs a credible probability of that claim being checked — which is what standards bodies, laboratories, conformity assessment and trading standards already exist to do:
Digitalisation does not remove this regulatory function — it lets it become more targeted: risk-based surveillance concentrated on products, manufacturers or supply chains with unusual patterns, complaints or inconsistencies, rather than uniform inspection of everything.
