U3: How to Verify Green Certifications
For energy and chemical products like Hydrogen, Methanol, and Ammonia, verifying supplier certifications (ISCC, ISCC PLUS, or RSB) is a crucial risk control step.
Combined with the latest industry dynamics (such as the 2026 verification requirements) and standard systems, here is a "Five-Step Verification Method":
Step 1: Official Database Verification (Check Identity & Validity)
This is the most basic and authoritative step. Do not rely solely on PDF certificates provided by suppliers, as they may be expired or suspended.
- Access Databases: Use the ISCC System Database or RSB Global Certification Database.
- Key Info: Ensure the status is "Valid" (not Suspended or Withdrawn). Check the "Valid Until" date (usually 1 year).
- Scope: Confirm the scope (e.g., ISCC EU for biofuels, ISCC PLUS for chemicals).
Step 2: Carbon Footprint Data Verification (Check Values & Standards)
This is where "greenwashing" often occurs.
- Request Reports: Ask for verification statements from third-party institutions (SGS, TÜV) based on ISO 14067 or LCA.
- System Boundaries: The report must include "Cradle-to-Gate" data, including the "Embodied Carbon" of equipment (e.g., electrolyzers).
- Thresholds: Compare values against standards (e.g., EU Red Line: ≤3.4 kgCO₂/kgH₂).
Step 3: Supply Chain & Voucher Verification (Check Authenticity)
Check how the supplier proves raw material compliance.
- Mass Balance vs. Physical Segregation: Verify Transaction Certificates (TC) for mass balance or storage records for segregation.
- Key Red Flags: For electrolysis, demand "real-time matching" proof (15-minute level) of green power, not just annual certificates.
Step 4: Export & Financing Compliance
- Export (EU): Confirm compliance with RED II/III and RFNBO requirements.
- Financing: Banks require ISCC EU/PLUS certificates. Verify data meets EU ETS or CBAM requirements.
Step 5: Risk Warning
Terminate cooperation if:
- Suppliers only use "color labels" without ISO 14067 reports.
- Data is too perfect (e.g., near 0 without explanation).
- There is a "boundary cut" (ignoring upstream emissions)
- Does it meet the EU's requirements for geographic correlation and hourly metering for PPAs?"
