How METI Source Network Works
The process for embedding verifiable trust in sustainable exchange
METI™ (MillPont Environmental Trust Infrastructure) operates as a geospatial clearinghouse and trust network, transforming environmental data management in nature-based raw material supply chains. At its core, METI introduces Secure Source IDs (SSIDs) - digital deeds linked to Sources of environmental outcomes. These digital deeds provide a secure, dynamic, and interoperable network for connecting nature-based raw material value chains with environmental data markets.
Secure Source IDs (SSIDs)
SSIDs are digital deeds that transform how environmental outcomes are tracked, verified, and managed. By linking each Source to an SSID, METI enables:
Ownership Verification & Validation: Each SSID is tied to a specific Source and its environmental outcomes, ensuring accurate claims and compliance with market standards - mitigating double-counting and greenwashing.
Security: Encrypted identifiers protect data integrity and ownership while safeguarding against fraud or duplication.
Interoperability: SSIDs are designed to integrate seamlessly with multiple platforms, markets, and regulatory frameworks, reducing friction across supply chains, registries, and marketplaces.
Dynamic Functionality: SSIDs evolve over time, capturing updates to claims, monitoring status changes, and ensuring outcomes remain relevant and actionable.
How METI Works: Step-by-Step Process
Submission of Sources
METI Members (e.g., Perdue) submit Sources from agricultural, forestry and land-use projects to METI’s Clearinghouse. These Sources include:
Geospatial boundaries of project fields. (required)
Management timelines - Valid From: Valid To - specifying the duration of claims (required)
Project Methodology, Practice Data, and Verification Status (optional)
Process & Validate
The Clearinghouse reformats and encrypts incoming data, checks for consistency and privacy protection, and validates exclusivity by comparing submissions against the METI Network, Protected Areas, and public registries (e.g., Verra, CAR, ACR, Gold Standard, etc.).
Issue SSIDs & Linking to Outcomes
Validated Sources receive an encrypted Secure Source Identifier (SSID) - a digital deed - which members attach to verified outcomes and move through their supply chain. The SSID ensures traceability, prevents double-counting, and gives buyers confidence in each transaction and link in the supply chain.
Authenticate & Monitor
Buyers and auditors authenticate claims through the Source Ledger. METI continuously monitors SSIDs for ongoing exclusivity, compliance with Rulebook standards, and integrity until the claim expires.
Key Benefits
Trust, Transparency & Data Privacy: SSIDs provide verifiable and traceable assurance of environmental claims ownership, while protecting the privacy of farmers and land-owners.
Scalable Market Integration: Interoperability ensures compatibility across platforms, registries, and value chains.
Dynamic Accountability: SSIDs adapt to updates in environmental outcomes and ownership, ensuring continuous relevance and detection of conflicts - historically and on an ongoing basis.
Efficient Ownership Management: SSIDs simplify complex transactions by creating a secure, traceable link between Sources and outcomes, ensuring claims are unique, exclusive, and readily auditable.
METI empowers stakeholders to connect raw material value chains with climate markets, fostering a sustainable future. By leveraging SSIDs as digital deeds, METI ensures that environmental claims are not just credible but also verifiable, authentic, and traceable - to the source - at scale.
