To reduce the impact of the transportation sector on the environment and climate, policymakers and industry are driving the transition from conventional internal combustion engine vehicles to electric vehicles. A much-discussed issue in this process is the greenhouse gas balance of vehicles over their entire life cycle, i.e., the amount of pollutants emitted from the production of a vehicle, through its use and scrapping as a whole. This balance makes vehicle emissions comparable in a holistic way beyond pure consumption on the road. How electric cars compare with internal combustion engines and how sustainable batteries will become in the future reveals Johannes Buberger, a doctoral student at the University of the Federal Armed Forces in Munich and co-author of the studio "Total CO2-equivalent life-cycle emissions from commercially available passenger cars."

The Universität der Bundeswehr (UniBw M) is a university in the division of the Federal Ministry of Defense. It is one of two universities established by the Bundeswehr for the academic training of its officer candidates and officers. Within the framework of the four research aspects Energy & Propulsion, Space & Transport, Networking & Autonomy, and Opportunities & Impacts, holistic solutions are developed based on the future mobility needs of society and the armed forces, ranging from spatial planning to the local generation of C02-neutral energy carriers (electricity, hydrogen, ethanol), innovative drive trains, autonomous driving, and the networking of transport infrastructure, vehicle and user.
Johannes Buberger started privately a few years ago to collect data on the pollutant emissions of passenger cars over their entire life cycle in order to compare them. Later, he pursued the topic at the chair. As part of his projects at the Center for Digitization and Technology Research at the University of the German Armed Forces, he and colleagues compiled data from 790 vehicles.
