Entering data on business traffic

On the page enter data you will find general information about filling in an Envirometer and how to operate the entry screen. Below, you will find specific information about entering data on business traffic (work-to-work traffic). In finetuning you can select which items are shown in your Envirometer.

Pay attention to

Company or leased cars

In case of SKAO CO2 Performance Ladder it is important to fill in business trafic in liters fuels (instead of kilometers). Except for the invoiced business trips with private cars, enter these in kilometers.

Methods for collecting the data

There are several methods to measure or estimate these data. You may have kilometre data for part of the business traffic and fuel data for another part. Clarify in your notes which information is stored where.

  1. Ask for an annual total with the lease company and/or fuel supplier and/or rental car company and/or car sharing company and/or company subscriptions (for instance the business card of the Dutch Railways (NS))
    Ask for an annual total of the fuel taken or kilometres driven with the lease company or the fuel supplier.
  2. Deduce from the fuel costs total
    If bookkeeping has an item for fuel costs, this may be used to convert the costs into litres of fuel based on the average price per litre (see for instance www.cijfernieuws.nl).
  3. Take down the mileage of the vehicles
    By taking down the mileage of each vehicle at least at the beginning (or end) of every year, the number of kilometres driven per year can be calculated.
  4. Deduce from declarations for business travel
    Ask the salary administration department or the financial department for a survey of the kilometres and/or expenses claimed. Please note that the declarations for public transport and vehicles may well be handled separately for tax purposes. If only the costs are registered, the mileage can be determined by dividing the number of kilometres by the reimbursed costs per kilometre. The rules of thumb are:  

Please note that a company car (leased, self-administered or private/business) on average drives 33,000 km a year. 35% of these kilometres are business-related. The most important reason for trips is commuter traffic at 40% (over 13,000 km a year). The private use comes to 25% of the kilometres driven, that is over 8,000 km a year.

Please note that the key indicators for business traffic such as (km business traffic/fte) are based on the environmental data entered, instead of on the costs. That is to say that if you enter only the expenses without making an estimate of the mileage involved, the item will be counted as zero kilometres, and so the indicator will show a (much) lower number.
