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.
