Car

The calculator determines the consumed fuel mass from efficiency and distance. Subsequently GHG-emissions from the fuel production and combustion are calculated.

Train

The calculator uses selected the train and the distance travelled to determine the CO2-Emissions.

Plane

The calculator uses the traveled distance to calculate the fuel mass consumed per passenger. Subsequently the GHG-emissions from kerosene combustion and provision are calculated.

It is important to enter only data for single/return flights, because the LTO consumption has to be added to each flight.

Truck

The GHG-emissions of trucks are calculated based on the following assumptions:

• GHG-emissions are mainly referred to their use phase, therefore production and end of life aspects are not considered.
• The GHG-emissions are calculated with an average workload of 85%.
• GHG-emissions from fuel production are based on EU-15 values.

Ship

The GHG-emissions of ships are calculated based on the following assumptions:

• GHG-emissions are mainly referred to their use phase, therefore production and end of life aspects are not considered.
• GHG-emissions from fuel production are based on EU-15 values.
• The container ship is calculated with a tonnage of 27500 dwt.
• The bulk carrier is calculated with a tonnage 105000 dwt.
• The barge is calculated with a tonnage of 1228 dwt and a workload 76,9%.

Freight Train

The GHG-emissions of trains are calculated based on the following assumptions:

• GHG-emissions are mainly referred to their use phase, therefore production and end of life aspects are not considered.
• GHG-emissions from fuel production are based on EU-15 values.
• GHG from electricity production is based on values of the “Deutsche Bahn” grid mix.
• The electric traction is calculated with an average workload of 51%.
• The diesel traction is calculated with an average workload of 60%.

Cargo Plane

The GHG-emissions of planes are calculated using the following assumptions and data:

• GHG-emissions of planes are mainly referred to their use phase, therefore production and end of life aspects are not considered.
• The calculation of the fuel consumption is based on EMEP/CORINAIR Emission Inventory Guidebook 2005 - Air Traffic.
• The calculator uses an approximation curve to calculate the burnt kerosene mass.
• Additionally a separate LTO (landing take off) consumption is assumed.
• The GHG-emissions from the kerosene combustion are multiplied with a RFI-factor of 2.7.
• The provision of fuel is linked to the country where the plane takes off.
• GHG-emissions are calculated from values for EU-15.

The calculator uses a sample cargo plane, and an estimated workload (wl) and payload (pl) for each flight type.

• Boeing 747-400 - pl=112.63 - wl=57%

It calculates the fuel mass per tonne kilometer.

Subsequently the GHG-emissions from kerosene combustion and provision are calculated.

It is important to enter only data for single flights, because the LTO consumption has to be added to each flight.
