EcoTransIT is an online emission calculator and enables users the quantification of energy consumption and emissions of worldwide freight transport by trucks, trains, ships and airplanes. INFRAS in collaboration with the Institute for Energy and Environmental Research (IFEU) Heidelberg is in charge of the development of the methodology of EcoTransIT while the programming of the tool is conducted by IVE mbH Hannover. The EcoTransIT consortium consisting of DB Schenker, Gebrüder Weiss, Gefco, Geodis, Green Cargo, Greencarrier, Hamburg Süd, Hapag-Lloyd, Austrian Railways, SBB, SNCF, System Alliance Europe, Trenitalia and International Union of Railways (UIC) is responsible for the funding.The methodology of EcoTransIT has been currently revised substantially by INFRAS and IFEU. The calculation of energy consumption and greenhouse gas emission is now carried out in accordance with the new European standard EN 16258. For each calculation EcoTransIT provides a declaration fulfilling the requirements of the standard EN 16258. Furthermore the emission factors used particularly for the calculation of air freight have been updated fundamentally.Energy consumption and emissions of transport chains can be calculated free of charge by following the link: www.ecotransit.org.
