SEM004: Circularity Content Consistency

Severity: Warning Category: Semantic Validation

Description

The recycledContent percentage should not exceed recyclableContent.

Rule Details

This rule checks logical consistency in circularity metrics. While a product can contain more recycled material than it can be recycled into (due to contamination or mixed materials), this is flagged as a warning for review.

Example

Invalid

{
  "credentialSubject": {
    "circularityScorecard": {
      "recycledContent": 0.85,
      "recyclableContent": 0.60
    }
  }
}

Message: recycledContent (0.85) exceeds recyclableContent (0.60)

Valid

{
  "credentialSubject": {
    "circularityScorecard": {
      "recycledContent": 0.40,
      "recyclableContent": 0.85
    }
  }
}

How to Fix

Review the circularity metrics:

  1. Verify recycledContent value (% of product from recycled sources)
  2. Verify recyclableContent value (% of product that can be recycled)
  3. If values are correct, document the reason in metadata
