Fleet Environmental Action and Assessment (FLEAT)

Download PDFDownload PDF
FLEAT had the objective to increase energy efficiency for different types of fleets: fleets of public authorities, public transport fleets, private fleets with mainly company cars, private fleets with mainly utility vehicles. FLEAT offers existing tools and instruments to fleet operators to increase energy efficiency in 3 fields: improve energy efficiency and environmental performance of the vehicle fleet, encourage energy efficient use of vehicles and support energy efficient use of the fleet with mobility management actions. 37 pilot actions ran in different fleets focussing on different types of actions. Towards policy makers FLEAT summarised and disseminated effective policy instruments for supporting more energy efficient fleets. Pilot actions ran in Belgium, Austria, Italy, Germany, the Netherlands, Romania and Greece. A direct reduction of 4,3 kton CO2 was achieved, the multiplier effect is estimated to be 0.087 Mton CO2 reduction.


  • Different types of actions in the field for energy efficient fleet management were implemented: low carbon vehicles (green car policy, CNG-vans, electric vehicles, ...), driving behaviour (ecodriving training, long term monitoring & feedback schemes, ...), mobility management (improved logistics, commuting, …). In total more than 37 actions were implemented in the vehicle fleets of private companies, public institutions and public transport companies.
  • A total of 4.300 tons of CO2 were directly saved in the pilot actions, with the largest contribution from ecodriving actions. If all vehicles in the participating fleets were to be included in the action, more than 30.000 tons of CO2 would be saved annually.
  • Insight was gained in effectiveness of different measures in different circumstances (lease fleets, utility vehicles, buses) by means of a harmonised monitoring & assessment approach. Effectiveness of clean vehicles, ecodriving courses and mobility management was assessed.
  • Recommendations for policy makers on supporting programmes and learnings from pilot actions & networking were listed and are available at the FLEAT-website.
  • A report on the monitoring and evaluation of the paticipant fleers and a toolbox for fleet operators with info on possible measures are available at the FLEAT-website.

Lessons learned

  • The many pilots on ecodriving proved that these courses are cost effective, and the greatest benefit can be reached with heavy duty vehicles (trucks and busses). Fuel reduction and thus CO2-reduction of more than 6% can be achieved for light duty, and this increases to more than 9% for trucks.
  • Since no additional costs are related to implementing a green car policy, this is the most cost effective measure to implement in a company car fleet. In the FLEAT pilot actions on car policy, the new vehicles emitted 10,5% less CO2.
  • The use of CNG-vehicles is most beneficial in a light duty vehicle fleet (eg. vans). The technology is already in a mature state for light duty which means the additional cost for a CNG-vehicle is relatively low. This combined with a low usage cost, mainly due to the low fuel price of natural gas, makes it a competitive technology. The environmental benefit of CNG lies not only in a lower CO2-emission, but also in a very low emission of PM and NOx, which is of high importance in urban area
