CO2 Emissions Calculator

The CO2 Emissions Calculator substitutes your inputs (Consumption (L/100km), Annual km) into the standard expression: CO2 g/km = Consumption (L/100km) × 23.2 × 10; CO2 kg/year = Consumption (L/100km) ÷ 100 × Annual km × 2.31. Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Enter the vehicle data and required values.

2. 2

   Step 2

   Hit "Calculate" and the result is computed automatically.

3. 3

   Step 3

   Use the result while keeping the context and units in mind.

4. 4

   Step 4

   The breakdown lists your inputs — Consumption (L/100km), Annual km next to the value computed by CO2 g/km = Consumption (L/100km) × 23.2 × 10; CO2 kg/year = Consumption (L/100km) ÷ 100 × Annual km × 2.31; read it before relying on the number.

   Step 5

   Adjust one input at a time and compare scenarios: change Consumption (L/100km) and re-run to see which variable moves the co2 emissions result most.

• 1

  The CO2 Emissions Calculator needs every variable in consistent units — Consumption (L/100km), Annual km — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Treat the CO2 Emissions output as a computed reference, not a guarantee: where money, health, or compliance is involved, have a professional confirm the inputs and the interpretation before you act on the number.

• 3

  Enter values in the units the CO2 Emissions fields expect — Consumption (L/100km), Annual km and the rest; mismatched units are the most common way a correct formula yields a wrong number no calculator can detect.

• Percentage conventions differ by field: some CO2 Emissions inputs expect annual km as a whole number (5 for 5%), others as a decimal (0.05). The two forms are off by ×100 — match the field's label or example.

• Zero and negatives can sit outside the formula's domain: zero annual km may make the CO2 Emissions undefined, and a negative consumption (l/100km) still returns a number. Check each input is inside the range the quantity allows.
