Example 1 — intensity 120 g/km × 100 km
- Mode: intensity
- 120 g/km
- Distance: 100 km
- No WTT
CO₂ ≈ 12 kg
Assumes metric units.
Trip CO₂ emissions
Estimate CO₂ mass from type-approval intensity, fuel burn, or BEV grid energy — with scenario compare, optional WTT and yearly scaling.
Educational model. Units follow the header. Example cards below assume metric defaults (km, L/100 km, g CO₂/kWh). Not a type-approval or ESG audit.
Result
Enter data and click Calculate.
How results are calculated
Intensity: kg = (g per user distance) × distance / 1000.
Fuel: liters from (consumption → L/100 km SI) × kg CO₂/L.
BEV: kWh × grid intensity → kg.
Optional WTT = % of trip emissions. Computation logic unchanged from the previous version.
How to use the calculator
- Pick a mode (intensity / fuel / BEV).
- Enter parameters and distance (header units).
- Optionally enable A/B compare, WTT and trips/year.
- Use the metric examples below for known results.
Usage examples
Example 2 — fuel 7 L/100 × 200 km (petrol)
- Mode: fuel
- 7 L/100 km
- Petrol
- 200 km
CO₂ ≈ 32.34 kg
2.31 kg CO₂/L × 14 L.
Example 3 — EV 18 kWh/100 × 350 × 100 km
- Mode: EV
- 18 kWh/100 km
- Grid: 350 g/kWh
- 100 km
CO₂ ≈ 6.3 kg
18 kWh × 350 g/kWh.
FAQ
Which modes are available?
Type-approval intensity, fuel use + fuel type, and BEV (kWh × grid intensity).
Which units are used?
Header units (metric: km, L/100 km, kg; US: mi, mpg, lb). Example cards assume metric defaults.
What is WTT?
Optional well-to-tank add-on (% of trip emissions) — supply-chain estimate, not a measurement.
Does A/B comparison change the formula?
No — same mode for both; the result shows the mass difference.
Where do fuel factors come from?
Fixed kg CO₂/L: petrol 2.31, diesel 2.68, LPG 1.55 (educational model).
Is BEV zero-emission here?
No — we count grid electricity emissions at the entered intensity.
What do the examples show?
They fill mode + fields: 120 g/km×100 km → 12 kg; 7 L/100×200 km petrol → 32.34 kg; EV 18 kWh/100×350×100 km → 6.3 kg (metric, no WTT).
When should I not rely only on this?
For ESG reporting or type-approval — use official vehicle data and power-mix figures.
