Streamlining Emissions Data Sharing: Ensuring Supply Chain Transparency

Problem: With the global push to manage greenhouse gas (GHG) emissions, ensuring accurate and transparent data exchange across supply chains is crucial. Traditional methods struggle with data integrity and trust between supply chain participants.

Why Current Systems Fail:

  • Centralized systems are prone to data tampering.
  • Sharing emissions data across multiple supply chain actors is inefficient, especially when actors span borders.

Solution: Verifiable Credentials for GHG Data​

Verifiable Credentials (VCs) enable decentralized, tamper-proof data sharing across supply chains, ensuring transparency while preserving data integrity.

How It Works​

  1. Issuance: Emissions data is captured and stored as a VC by a certified authority (e.g., environmental auditor).
  2. Storage: Each supply chain participant (e.g., a mine or production facility) stores the VC in their digital wallet.
  3. Presentation: The VC is shared with downstream partners or regulators to verify emissions data.
  4. Verification: Verifiers (e.g., regulators) check the data for authenticity using cryptographic proofs.

Benefits​

  • Data Integrity: VCs ensure emissions data can’t be tampered with.
  • Trust: Verifiers gain confidence that the data comes from legitimate sources.
  • Regulatory Compliance: Easier adherence to international regulations by sharing trusted emissions data across borders.
