These baselines are based on data available in NTMCalc 4.0, literature reviews and expert interviews. The settings aim to reflect on general road transport. In general we recommend use of real data if available at sufficient quality. NTM default data are conservatively assessed and should if used thereby not enable low emission calculations. Furthermore they should promote transport suppliers to present their real data in relation to NTM default data, hence being used in the transport service procurement process.

Clarifications and abbreviations

* Traffic data

Performance in relation to vehicle operation expressed as emissions or energy use per vehicle * km. Useful if transport service is carried out by a dedicated truck.

** Transport data

Performance in relation to vehicle operation expressed as emissions or energy use per ton * km. Useful if transport operation is carried out as a shared truck service. Default load factor [%-weight] includes empty positioning of truck.

Type of vehicle

Describes type and their gross weight

Load factor weight

Refers to actual pay weight

Default data

Based on general settings within NTMCalc 4.0.

Energy

Use of energy, including fuel production/ distribution and the combustion (wtw).

CO2e

Emissions of carbon dioxide equivalents including fuel production, distribution and the combustion (wtw).

Road type

Describing the type of road and corresponding traffic situation for the trucks.

Engine emission standard

Describing the emission standard of the vehicle used for these default values. For these vehicles Euro VI is used as a standard setting.

Fuels quality

Describing the diesel quality and ratio of biomass blend. The average blend in of biofuels in Europe is presently above 6%, in these data the setting is 7% since we expect this ratio to increase.

Road gradient

Describe road topography as this has an influence on fuel consumption
