Introduction to METI™

MillPont Environmental Trust Infrastructure (METI™) is a public clearinghouse for environmental assets (carbon, water, biodiversity, etc.). Built on the global Domain Naming System (DNS), METI™ stores only the metadata required to establish uniqueness and provenance, allowing private registries to mitigate double counting risk and providing buyers with a single point of reference to validate claims. Our technology applies the latest advances in encryption to protect Personal Identifiable Information (PII) such that the data METI does store (location, time ranges), are obscured such that neither MillPont nor the public may ascertain their true values. This approach permits certain computations such as location conflict and time range overlap to be computed without ever revealing the protected data.

Fundamentally METI deals with two objects: sources and certificates - both of which are stored and visible on public DNS.

Source
The land-based origin of environmental benefits represented by the spatiotemporal extent of the project claim (e.g. an agricultural field-based project from 2020 to 2030). Sources must be unique per attribute (carbon, biodiversity, etc.) to prevent duplicated environmental assets entering the market.

Explicitly personally identifying information, such as landowner name, is excluded from METI. Necessary information that may be used to ascertain personal information such as location data is obscured using Fully Homomorphic Encryption (FHE) allowing for spatiotemporal conflict to be evaluated without anyone being able to ascertain the plaintext location data.
Certificate
A market-based instrument representing the property rights to the outcomes of environmental projects. Certificates represent outcomes for a fixed time range originating from one or more sources. Certificates may encapsulate only one attribute type (carbon, biodiversity, etc.).

Acceptable use policies are embedded in the certificate defining allowed transaction types (e.g. immediate retirement after sale only, secondary market trading allowed, vertical supply chain co-claiming allowed).The provenance (history of ownership) is also embedded in the certificate, describing the entities participating in transactions against the instrument, transaction, type, and time of transaction.

As open infrastructure, the entire METI™ directory is visible to the public. However, privileged functionality allowing for the creation and modification of records is reserved for participants enrolled in one of the two programs listed below:

For Originators.

METI™ Originate

  • Create unique sources representing your project's spatiotemporal boundaries.
  • Generate new certificates and link them to your sources.
  • Define and embed certificate usage policies.
  • Issue certificates to Buyers.
For Buyers.

METI™ Transact

  • Receive certificates issued to you by Originators.
  • Transfer certificate ownership.
  • View and update certificate provenance.
  • Retire certificates.
