Buyer's Guide to Methane Carbon Credits
Independent framework for evaluating methane abatement credits using GWP100 (~28×) framing. Focus on measured fugitive emissions, permanence, and defensible diligence standards.
Executive Summary
Methane abatement credits are framed here on a GWP100 basis, where methane is ~28× CO₂. Early diligence is critical for buyers comparing quality, permanence, and additionality. Independent audits and calibration logs separate high-integrity credits from commodity alternatives.
Key Evaluation Criteria
Four technical criteria backed by ORR Energy Services' plugging expertise and Hetek measurement equipment.
Additionality Assessment
- Would the methane emissions have continued without the project?
- Is there a clear counterfactual scenario demonstrating additional impact?
- Are there regulatory requirements already mandating this activity?
- Does the project go beyond business-as-usual practices?
Measurement Rigor
- Are emissions measured directly rather than estimated from factors?
- Is measurement equipment calibrated and third-party verified?
- Are multiple measurement campaigns conducted for accuracy?
- Is baseline data collected over sufficient time periods?
Registry Credibility
- Is the registry recognized by international standards bodies?
- Does the methodology undergo independent review?
- Are credits tracked on blockchain or immutable ledger?
- Is there transparency in methodology documentation?
Permanence & Verification
- Are emission reductions permanent and irreversible?
- Is there ongoing monitoring and verification?
- Are third-party auditors involved in verification?
- Is there insurance or guarantee against reversal?

Quality Concerns
How CH4mber Credits Measure Up
CH4mber credits exceed all quality criteria with third-party auditors certifying permanent emission reductions. Field measurements verified using Hetek high-flow sampling equipment with calibration logs.
✓ Clear Additionality
Orphaned wells have no responsible party and would leak methane indefinitely. Creates local jobs while reducing state orphan-well lists.
✓ Measurement Rigor
Hetek high-flow sampling equipment with calibration logs, GPS coordinates, and lab results. Raw data files hashed on-chain for anyone to verify.
✓ Registry Credibility
Registry-agnostic issuance posture with complete diligence documentation and third-party verification support.
✓ Permanent + Co-benefits
API-compliant plugging eliminates emissions permanently. Caps wells within critical aquifers, removing surface hazards.
