6. Evaluation of importance of input data ParameterImportance Availability of statistics Notes /Particular Issues Total number of vehicles per class   Question is the scooter and mopeds registration availability Distinction of vehicle to fuel used   Question is the availability of records for vehicles retrofitted for alternative fuel use Distribution of cars/motorcycles to engine classes   Not important for conventional pollutants, more important for CO2 emission estimates Distribution of heavy duty vehicles to weight classes   Vehicle size important both for conventional pollutants and CO2 emissions Distinction of vehicles to technology level   Imported, second-hand cars and scrappage rates are an issue Annual mileage driven   Can be estimated from total fuel consumption. The effect of mileage with age requires attention. Urban driving speed   Affects the emission factors Rural, highway driving speeds   Little affect the emission factors, within their expected range of variation Mileage share in different driving modes   Little affect emissions, within their expected range of variation
