In line with its vision to increase transparency on the environmental impact of the freight transport and to demonstrate the continuous improvement of EcoTransIT methodology and EcoTransIT World (ETW) calculator, EWI members have commissioned their scientific and IT partners to provide an updated methodology report. The methodology was already embedded in the calculator; it follows the guidelines of the standard EN 16258 “Methodology for calculation and declaration of energy consumption and greenhouse gas emissions of transport services” and integrates latest research available for the air pollutants.
