CONCEPTUAL FACTOR PATH
Net CO₂e = (((gal × manure density × VS% × methane potential × baseline MCF × methane density) × capture efficiency × destruction efficiency) × methane GWP ÷ 1,000) − project emissions
Calculation Run Details preserves the actual inputs, selected factor snapshot, intermediate values, unit conversions, and project-emissions deduction.
FACTOR LIBRARY
Calculation factor versions
Factor ID identifies the database record; version and effective dates identify
the assumptions reproduced by a calculation run.

REPRODUCIBILITY CONTROL
Completed runs retain the exact factor ID and version. New factor versions never silently rewrite historical calculations; Calculation Run Details preserves the snapshot actually used.
NEXT EVIDENCE
Verify the selected version inside a completed calculation run.
Factors define assumptions; run details prove which inputs produced each daily result.
