Baseline
The published field result used a 90-day operating baseline across 118 vehicles at one depot.
FUEL AND ENERGY / MEASUREMENT
Make the calculation
traceable.
Keep the baseline, operating normalization, observation window and annualization assumptions separate.
Post-change observation
The reported comparison used a complete 31-day post-change period and a normalized fuel-intensity reduction of 8.1%.
Annualized estimate
The published annualized estimates are 168,339 litres, $260,925 in fuel cost and 448 tonnes of project-level CO₂e. They project the measured 31-day result over a year.
Scenario model
The calculator multiplies annual baseline litres by the assumed reduction and fuel price. Emissions estimates use 2.66 kgCO₂e per litre.
Accounting boundary
Report project emissions savings, fuel-cost savings, labour, reporting and internal carbon value separately. Carbon credits and corporate inventory adjustments require their own verification and accounting.
CALCULATOR
Litres saved = annual baseline litres × assumed reduction
Fuel cost saved = litres saved × fuel price
Tonnes CO₂e avoided = litres saved × factor ÷ 1,000
