Calculate Scope 1 Fleet Emissions

Calculate Scope 1 fleet emissions using activity data, matched factors, and documented assumptions.

Calculate controlled fleet emissions from 18,400 gallons of gasoline, 9,600 gallons of diesel, and 42 unknown fuel-card transactions. Classify controlled combustion as Scope 1, match fuel units to fuel-specific factors, and document unresolved transactions. The common shortcut is to multiply total fleet spend by one generic transport factor because the fuel-card export is messy. That hides fuel mix, prevents operational variance analysis, and leaves unknown transactions buried inside the total. Step 1 Confirm the vehicles are company-controlled and the fuel is combusted by those vehicles, so the source belongs in Scope 1. Scope classification comes before arithmetic. If the vehicles…
