Article: https://yenra.com/wiki/Carbon_capture_and_storage/

Purpose: evaluate a carbon capture and storage claim through the complete chain. Use consistent useful output and reporting periods. Record proposed, tested and sustained operating evidence separately.

Facility, source process, location and stage:
Claim/document/date and responsible entity:
Useful product/output and reporting period:
Reference case supplying the same product:
Capture-system inlet CO2 and boundary (tonnes):
Captured CO2 (tonnes) and capture rate denominator:
Transferred CO2 and transport route/operator:
Verified stored CO2 and receiving site/operator:
Difference between captured and stored quantities, with explanation:
Uncaptured streams, energy use and other project emissions:

FICTIONAL ACCOUNTING EXAMPLE
Reference emits 1,000 tonnes CO2 for a stated useful output.
Capture case at equal output has 1,200 tonnes entering capture.
90% capture = 1,080 tonnes captured and 120 released there.
Another 80 tonnes emitted elsewhere inside the assumed boundary.
All captured CO2 is assumed verified stored.
Project emissions = 120 + 80 = 200 tonnes.
Avoided = 1,000 - 200 = 800 tonnes, or 80% of reference.
These are invented values. A real lifecycle calculation must include corresponding reference upstream emissions, all project streams, other greenhouse gases, losses, uncertainty and the same output service. State CO2 versus CO2-equivalent units and the chosen time horizon.

STORAGE EVIDENCE
Jurisdiction, permitting authority and actual permit:
Site characterization, area of review and other wells:
Construction/integrity evidence and monitoring plan:
Plume/pressure observations and reporting period:
Corrective action, post-injection care and closure criteria:
Financial responsibility and responsible party by phase:
Capture/transport/storage outage contingency:

DECISION
Missing project-stage evidence:
Missing mass-balance or lifecycle evidence:
Unresolved commitment / party / document required:
Comparison with realistic same-output alternatives:
