calcEF_CO2.Rd
Calculates the appropriate carbon dioxide (CO2) emission factor (g/kWh) for the given parameters.
calcEF_CO2(engineType, location, loadFactor = NULL, main_aux_boiler = "main")
engineType | Engine type (vector of strings) (see
|
---|---|
location | Location of vessel (vector of strings). Valid values are:
|
loadFactor | Fractional percentage (between 0 and 1) of main engine required to propel vessel at given speed (vector of numericals) (see ShipPowerModel library). This parameter is optional. By default, it is not used and the resulting emission factor is independent of engine load. |
main_aux_boiler | Is this calculation for a propulsive (main), auxiliary (aux), or boiler engine? Options:
|
EF_CO2
(g/kWh) (vector of numericals)
Location is important for determining the fuel being used, as type of fuel typically used varies by location.
For more information about calculating CO2 emission factors, see Section 3.5.6 of the Port Emissions Inventory Guidance.
