  1. UNECE Joint Task Force on Environmental Indicators Item 3 (f) Average Age of Road Motor Vehicle Fleet

  2. Importance of age of vehicle fleet • According to the EEA, road transport is responsible for 17.5 % of overall greenhouse gas emissions in Europe and its emissions increased by 23 % between 1990 and 2009. • The age of a road motor vehicle has an impact on the amounts of the various types of emission. • According to the EEA, average CO2 emissions for new cars registered in 2011 were 3.3% less than new cars registered in 2010. • See http://www.eea.europa.eu/themes/transport

  3. UK Experience • Road transport accounts for 19% of UK green house gas emissions. • Estimate of how emissions of different gases per km vary depend on vehicle speed for different vehicle types/ fuel type/ year of first registration (used as a proxy for Euro emissions class)/ engine size/ etc • http://assets.dft.gov.uk/statistics/series/energy-and-environment/climatechangefactsheets.pdf

  4. Regulatory Changes • To help achieve reductions in transport emissions, strict targets have been introduced in the European Union and other major economies for vehicle fuel efficiency. • Manufacturers are committed to achieving in a definite programme over time specific and gradually tighter fuel consumption levels for the new vehicles they produce • The size and importance of these economies has implication for all world vehicle manufacturers

  5. Technical Advances • Motor manufacturers have responded by improving the efficiency of vehicle engines and the aerodynamics of the vehicle to reduce fuel consumption.

  6. Implications • Each generation of vehicles is more fuel efficient and emits fewer emissions than earlier vehicles. • The average age of the vehicle fleet in a country is therefore a helpful indicator of the level of emissions created by that country’s vehicles

  7. Definitions • Vehicle fleet • Age of vehicle

  8. Vehicle fleet • All motor vehicles licensed to operate on a country’s roads at a given date • Passenger cars • Motor coach, bus or trolleybus • Truck • Road tractor

  9. Vehicle RegisterDate of first registration • Countries maintain registers of vehicles licensed to operate on their roads for • Police • Taxation • It is important for this indicator that these registers contain the date when the vehicle was first licensed for use • This date of first registration is normally the date to be used to calculate the age of the vehicle

  10. Problem • Used vehicles from abroad • The date of first registration in the country accepting foreign used vehicles will not properly reflect the date of manufacture or of first use • It will therefore underestimate the age of the vehicle and its emissions performance

  11. Date of first registration • This should be the earliest date of first registration of the vehicle in any country in which it has been registered. • The Harmonised Registration Certificate records this information for foreign second hand cards for all EU countries.

  12. Example • A Mercedes was registered in Austria with Austrian number plates for the first time in 2008 • In 2012, it was exported to Albania where it was reregistered and given Albanian number plates. • Two dates of first registration • 2008 Austria First country registration • 2012 Albania Second country registration • Chose the earliest i.e. 2008 if known or, if this is available, from the harmonised registration certificate

  13. First country registration not known • Adjust the date of first registration by some factor

  14. Provision of statistics • For every year’s data to be provided, a copy of the vehicle register is needed as it stood on a specific fixed date within the year e.g. • 1 January • 31 December • 30 June • Which of these is appropriate depends on the arrangements with the keeper of the register.

  15. Age distribution (1) • For each vehicle on the vehicle register • Determine its age from the date of first registration • Allocate each vehicle among the age groups • Age <= 2 years • 2 years< age <= 5 years • 5 years< age <= 10 years • Age > 10 years

  16. Age distribution (2) • Compile the totals for each age group and calculate the percentage each group represents of the total • This allows the calculation of an average age for the vehicle fleet
