Track transport indicators

This endpoint delivers a set of indicators that give an overview of the mobility trends of a region and the underlying drivers for transport footprints

All inputs, outputs and defaults can be seen in the Track Transport technical API docs.

Car and plane travel are major contributors to Norway’s consumption-based CO2e emissions. Additionally, challenges such as congestion, climate change, air pollution, and noise pollution plague urban mobility. This endpoint offers a comprehensive overview of the key indicators which have the greatest impact on domestic transport, enabling municipalities to monitor and analyse mobility trends. 

By utilising a range of indicators, municipalities can benchmark their performance against similar regions and gain insights into their current standing. Additionally, policymakers can leverage these indicators to assess the impact of new policies or evaluate the effectiveness of existing measures.

The endpoint outputs a set of indicators that gives the user an insight into the mobility trends of a region, from car ownership to kms travelled in different modes of transport. Additionally, the total carbon footprint associated with each indicator is also shown.


You must submit AreaID pertaining to your location (neighbourhood, municipality, county or country). You can find out the areaID for your location here.

You can submit which date you want to retrieve data for.


All figures are annual figures , and all footprint figures are given in kilograms of CO2e per capita.

For the given area, the user receives:

  • areaID and name of the area
  • A list of all available indicators for the area, containing
    • An indicator name
    • An indicator value
    • Unit of indicator value
    • A total footprint associated with the relevant indicator

Data sources

The indicators use a variety of data sources as described below. Reference names and sources have been listed, the full descriptions of data sources can be found in the footprints data sources support article.

  • National Vehicle Registry (Statens Vegvesen)
  • National Vehicle Use Datasets (SSB)
  • DEFRA GHG factors (DEFRA)
  • Flight travellers’ habit report 2019 at Avinor Airports 2019 (Avinor)
  • Telia Mobility Data (Telia Crowd Insights)

Additionally, the National household database (Folkeregisteret) is used to extract the number of households/people per region.


The necessary calculations are listed below for each indicator, as well as the total footprint associated with each indicator. Unless stated otherwise, total associated footprint values are derived from the Ducky Footprints CO2e emissions estimates, which provide individual footprint estimates for Norwegians at a neighbourhood level. 

  • carOwnership - The total number of vehicles from the National Vehicle Registry is divided by the number of households or people from the National household database to give us the number of personal vehicles owned per household or person.
  • Total associated footprint is the car footprint (footprint from personal vehicle travel)
  • kmFlownDomestic - The Avinor data is combined with Telia’s Mobility Data to produce an estimate of how many kilometres are flown domestically by Norwegian inhabitants.Avinor data dictates how many kilometres were flown domestically, while the Telia Mobility Data assigns these kilometres to specific municipalities and then divides them equally among each municipality’s inhabitants.
  • Total associated footprint is the domestic flight footprint, and is calculated by multiplying total kilometres flown by  domestic flight CO2e emissions as found in the DEFRA GHG Factors
  • percentageElectricCars - The total number of personal electric vehicles is divided by the total number of personal vehicles for each region to find the percentage of electric vehicles per region.
  • Total associated footprint is the car footprint
  • kmDriven - SSB’s National Vehicle Use Datasets give km driven per personal vehicle on a municipality basis, which is currently used to calculate this indicator.
  • Total associated footprint is the car footprint
