Abstract: This work describes a methodology for determining the average vehicle kilometres travelled by the private national car fleet in Ireland and estimating the disaggregated CO2 and NOx emissions from private vehicles in the Irish road transport sector for the period 2000-2005 using national car test records. The developed methodology facilitates the calculation of greatly improved estimates for vehicle kilometres under a range of constraint variables and thereby enables the disaggregated analysis of specific vehicle fleet groups and their associated activity patterns to support evidence-based policy development. The results indicate that while older vehicles are contributing significantly to car NOx emissions; newer cars produce a higher share of CO2 emissions than older cars in the vehicle fleet.
