EN 16258 Standard


The European Union has made commitments to fight climate change. Member countries have an ambitious goal to achieve by 2050: an economy with net-zero greenhouse gas emissions. This objective is at the heart of the European Green Deal and in line with the EU's commitment to global climate action under the Paris Agreement.

In order to achieve more accuracy, transparency and consistency in the calculation of energy consumption and greenhouse gas emissions in the logistics sector, the standard EN 16258 has been developed by the European Committee for Standardization.

Published in December 2012, the CEN standard provides for a common approach and framework for the calculation and declaration of energy consumption and emissions for transport services irrespective of the level of complexity. The standard includes standardized procedures for calculating emissions for the transport of individual consignments and partial loads and methods for determining data for sub- contractors.

Relevant vehicles

As the CEN 16258 standard is only relevant in the European Union, the relevant vehicles are: EUR_TRAILER_TRUCK, EUR_TRUCK_40T, EUR_TRUCK_11_99T, EUR_TRUCK_7_49T, EUR_VAN, EUR_CAR.

Conversion factors

Here are the factors for the calculation of energy consumption and greenhouse gas emissions (calculated as CO2-equivalents) in accordance with EN 16258 (TTW: tank to wheel, WTW: well to wheel).

The only engineType supported is COMBUSTION.

The fuel types LIQUEFIED_NATURAL_GAS and ETHANOL are not supported.

For dual fuels like CNG_GASOLINE or LPG_GASOLINE, a dualFuelRatio is supported.
