Where EEvap,fueling, = hydrocarbon emissions from fuelling, i = machinery
type, FC = fuel consumption in kg, EFEvap,fueling = emission factor in g
NMVOC pr kg fuel.
For tank evaporation, the hydrocarbon emissions are found from:

Where EEvap,tank,i = hydrocarbon emissions from tank evaporation, N = number
of engines, i = machinery type and EFEvap,fueling = emission factor in g

Where E = fuel consumption/emissions, N = number of round trips, T =
sailing time pr round trip in hours, S = ferry share of ferry service round
trips, P = engine size in kW, LF = engine load factor, EF = fuel consumption/emission
factor in g pr kWh, i = ferry service, j = ferry, k = fuel type, l =
engine type, y = engine year.
For the remaining navigation categories, the emissions are calculated using a
simplified approach:

Where E = fuel consumption/emissions, EC = energy consumption, EF =
fuel consumption/emission factor in g pr kg fuel, i = category (local ferries,
other national sea, fishery, international sea), k = fuel type, l = engine type, y

The emission factor inserted in (25) is found as an average of the emission
factors representing the engine ages which are comprised by the average
lifetime in a given calculation year, X:

For military and railways, the emissions are estimated with the simple method
using fuel-related emission factors and fuel consumption from the DEA:
( = )& ⋅ ()
where E = emission, FC = fuel consumption and EF = emission factor. The
calculated emissions for other mobile sources are shown in CollectER format
in Annex 2.B.15 for the years 2010 and as time series 1985-2010 in Annex
2.B.16 (NFR format).
