On-Line Commercial Vehicle Fuel & CO2 Emissions (Carbon Footprint) Calculator

---

This free on-line form instantly calculates the litres of fuel (diesel) consumed, cost and resultant CO2 (Carbon Dioxide) emissions of your commercial vehicle fleet. Simply enter information into the highlighted bright yellow fields and click "Calculate". (* minimum required fields).

The fields highlighted in pale yellow allow you to carry out more complex comparisons. The "Standard Vehicle" column should contain the base standard vehicle data whilst the "Comparison Vehicle" column can be used to calculate an increase or reduction in efficiency in comparison to the Standard Vehicle operation. If capital purchase costs are submitted, you will also be provided with the approximate payback period (i.e. the period taken to offset the fuel saving against the cost of achieving those fuel savings).

1 Gallon (Imperial) = 4.54609188 ltrs. 1 Mile = 1.609344 kms. Miles/Gallon (Imp) - Kms/Litre conversion = 0.354006. Litres/100km - kms/Litre conversion = 1/(Ltrs per 100km /100). Diesel:CO2 conversion of 2.63 kgs (0.00263 tonnes) per litre. Source: DEFRA www.defra.gov.uk/environment/business/envrp/pdf/envrpgas-annexes.pdf. Carbon Dioxide density 1.98 kgs per m3.

Whilst CO2 is directly proportional to litreage consumed, NOx and particulate emissions vary depending on engine and exhaust management systems.
