• 1. Overproduction is an information deficit: in an analog chain, samples, tooling and inventory substitute for knowledge the system does not yet have, and the sector's environmental metrics are the price of that substitution.
  • 2. The digital transition changes the cost curve, not the ethics: it converts the fixed costs of the analog information loop into variable ones, which is what makes short series, local manufacturing and long product lifetimes economically defensible rather than exceptional.
  • 3. Impact concentrates upstream: up to 80 percent of a product's environmental profile is set at the design table, so the tools of Chapters 2 and 3 carry more leverage than any downstream correction.
  • 4. The ladder is ordered by data dependency, not by ambition: each rung produces what the next one needs, so climbing one rung from your current position returns more than adopting a full stack at once.
  • 5. Industry 5.0 redirects Industry 4.0 rather than replacing it: the same RFID tag is an inventory tool in one reading and the data carrier of a product passport in the other.
  • 6. Digital tools are direction-neutral: regulation sets when data is required, and the business model decides whether digital capability reduces material throughput or accelerates it.
