ef_ive returns the base emission factors from the the IVE model. This function depend on vectorized mileage, which means your can enter with the mileage by age of use and the name of the pollutant.

ef_ive(
  description = "Auto/Sml Truck",
  fuel = "Petrol",
  weight = "Light",
  air_fuel_control = "Carburetor",
  exhaust = "None",
  evaporative = "PCV",
  mileage,
  pol,
  details = FALSE
)
