PEM Publishes Emission Target Calculator for Commercial Vehicle Sector


The Chair of Production Engineering of E-Mobility Components (PEM) of RWTH Aachen University has published a carbon footprint calculation tool for commercial vehicles on the internet. The online traffic target calculator is able to take into account various fleet stocks for the year of 2030 as well as different infrastructure scenarios and compare their effect on current emission targets and their costs. According to the RWTH institution, heavy commercial vehicles in particular cause an above-average proportion of CO2 emissions in German road traffic across all vehicles. Nevertheless, the focus of the current political debate is mainly on the large number of passenger cars.

"CO2 targets for 2030 currently not achievable"

"With the current developments in commercial transportation and the manufacturers' market announcements, the emission targets for 2030 cannot be achieved," says PEM Director Professor Achim Kampker. Due to higher product requirements, longer development cycles and less public interest, the first electric models are only just being presented or tested. "In addition, there will be no patent solution for this class of vehicle, as the respective requirements are too different and even contradict each other in some cases," Kampker says. The RWTH researchers had already pointed this out at the beginning of 2023 in their publication "Strategies for Achieving Emission Targets in the Commercial Vehicle Sector".

Emissions and investment costs for different fleet constellations

The new online tool was developed by PEM specifically to calculate CO2 emissions and investment costs on the vehicle and infrastructure side for different fleet constellations. This makes it possible to determine how large the proportion of alternatively powered commercial vehicles of different weight classes must be, depending on the type of energy supply, in order to achieve or even exceed the declared climate targets. The model was developed as part of the "LiVe" electric truck research project funded by the German Federal Ministry for Economic Affairs and Climate Action. The German-language emission target calculator is accessible online.
