Norbert Ligterink

Senior Research Scientist Vehicle Emissions @ TNO

Norbert Ligterink has PhD’s in theoretical nuclear physics (1996) and mathematical system theory (2007). He has worked in international academic research for many years. Since 2007 he works at TNO and translates the results of emission tests to the Dutch national vehicle emission factors, used in legal air-quality assessments and emission inventories. He also participates in the vehicle emission testing. For assessing the average emissions he complements emission data with vehicle fleet and vehicle usage information. He regularly updates the information on the average Dutch vehicle fuel efficiency from fueling data, for national and international assessments of the limited CO2 emission reduction with reducing type-approval values. His expert knowledge is also input in international discussions, as expert consultant on behalf on the Dutch government.
