Caculate the total emission with:
Emission(pollutant) = sum( Vehicles(n) * Km_day_use(n) * Emission_Factor(n,pollutant) )
where n is the type of the veicle
Value
Return a list with the daily total emission by interest area (cityes, states, countries, etc).
Note
the units (set_units("value",unit) where the recomended unit is g/d) must be used to make the ef data.frame
