How it works

The Sustainability Codex helps consumers, organizations and governmental institutions with sustainable purchasing. The Sustainability Codex values the sustainable performances and processes of suppliers on 4 core themes ofsustainability: CSR, MVI, CO2 & Circular Economy. The Sustainability Codex unlocks this information in an online database. Clear, comparable and reliable, because the Codex measures at standard level, which means that based on the achieved certifications of an organization the Codex gives an overall score on the 4 themes.

The Sustainability Codex integrated the Global Sustainable Metastandard that is based on existing international accepted sustainability standards on organization level:

The existing international accepted standards the Sustainability Codex is based on are:

  • ISO 26000
  • ISO 20400
  • ISO 14064-1 & PEF
  • BS 8001

For products their are 3 rates that will be shown by scanning the QR code:

  • Circular value
  • Environmental Performance
  • Health

The SUSTAINABILITY CODEX is a blockchain-based database and state-machine system designed to store data of certificates on organization level and to implement the CPF calculation method to be utilized as shared product and material registry of the Global Sustainable Enterprise System (GSES) platform. The main design principle is that product state-evolution in the physical world is mirrored by blockchain state-evolution in the digital world.

Each product is a tokenized series of materials managed by a smart contract on the blockchain. A product’s individual components and their material-tokens are ‘forged’ into a product, which after a product’s utility phase is complete, can be deconstructed again into its separate materials and re-assembled into a new product, enabling second lifecycle tracking and every subsequent usage of materials thereafter. Information about key CPF-values is provided by querying smart contract states, the individual tokens they hold and/or their specific underpinning transactions.
Data, once stored in a blockchain will likely be stored there forever.

This is often cited as being a disadvantage of the technology, but NDI and Capgemini are now working on a database to measure, track and market the circularity of products, where the integrity of historical data in a blockchain enables to trace each product back to its original creation.


Imagine looking at a specific country on a map, where you see an icon that represents some raw material, say iron ore, being delved from the Earth. After initial processing, the material then gets shipped to a production site, an offshore machine manufacturer, where the material is used during fabrication of a certain machine. This machine then is made operational on-site and after its lifecycle is complete, the machine is decommissioned. It’s safe to assume our collective circular mindset has gotten to a point where we naturally think it makes sense to re-use these materials. We can also assume there will be a need for raw or pre-processed materials (iron in this case) at pretty much any point in the foreseeable future.

Imagine the same map again, but this time you see all materials on Earth represented by icons at the same time, going through the process of being delved from the ground, to pre-processing, fabrication, utilization and finally decommissioning. We believe such a global repository is not only possible, combined with marketplace built on top it will unlock tremendous value that currently remains opaque and illiquid.
Every organisation can Tokenize their products and materials to enable ecosystems based on circularity – Direct ownership – Tradeability. Free up value that is currently locked tight and not calculated within products such as Real-Estate portfolios, off-shore manufacturing sites etc. Tokenize this value that your product contains.
