Method
How these estimates are built
Every figure on this page comes from a published, stated assumption and an arithmetic formula you can reproduce in a spreadsheet. Nothing is hidden behind a lookup we will not show you.
- Fueling labor uses $32/hour fully burdened labor and 45 minutes per retail refueling trip, across 52 weeks a year.
- DEF demand is calculated at 3% of the diesel volume your fleet size, annual mileage and fuel economy imply.
- Greenhouse-gas totals combine vehicle and stationary-asset fuel burn against per-gallon CO₂, CH₄ and N₂O factors shown live in the results panel.
- Renewable diesel is modelled as an 80% lifecycle reduction scenario against conventional diesel — a planning scenario, not a certified carbon-intensity score.
- Mobile fueling CO₂ reduction uses 60 lb avoided per diesel event and 51 lb per gasoline event.
Factor Table
Per-gallon emissions factors in use
| Fuel | CO₂ kg/gal | CH₄ g/gal | N₂O g/gal |
|---|---|---|---|
| Diesel | 10.21 | 0.1480 | 0.2580 |
| Gasoline | 8.78 | 0.2567 | 0.2130 |
| Renewable diesel / HVO | 2.042 | 0.0296 | 0.0516 |
Factors are held as plain constants in the page script so they can be revised as public reference data is updated. Results are planning estimates, not a regulatory lifecycle certification.

Turn the numbers into a supply program
Bring the output of any calculator to the supply desk and we will price the delivered program behind it.
1
Bulk fuel supply
Diesel, gasoline, off-road and renewable diesel on scheduled, keep-full or emergency delivery.
Open the quote desk →2
DEF / AdBlue supply
Bulk DEF, IBCs, drums, storage and dispensing sized to the annual demand the calculator returns.
