The IKEM study refutes the assumption that diesel engines are supposedly more efficient and thus, contribute to climate protection.
The IKEM study refutes the assumption that diesel engines are supposedly more efficient and thus, contribute to climate protection.
The share of diesel technology in the German car market has been increasing for years. Proponents argue that diesel cars contribute to climate protection in road traffic because they generate less CO2 due to more efficient engines. For this reason, the use of diesel technology will continue to be promoted through tax systems and legal frameworks.
The present study conducted by FÖS and IKEM on behalf of the German parliamentary group Bündnis 90 / Die Grünen shows, however, that the supposed climate advantage no longer exists.
The main reasons for this are increasing efficiency gains in other drive systems and the exploitation of the savings potential in diesel technology. Comparatively higher exposure to nitrogen oxides and other pollutants even makes diesel the most harmful of the technologies considered.

Deutsch: Der Anteil der Dieseltechnologie im deutschen Pkw-Markt steigt seit Jahren an. Befürworter_innen argumentieren bis heute, dass Diesel-Pkw so zum Klimaschutz im Straßenverkehr beitragen, da sie aufgrund effizienterer Motoren weniger CO_{2} emittieren würden. Die vorliegende Studie zeigt jedoch, dass der vermeintliche Klimavorteil bei der Senkung der durchschnittlichen CO_{2}-Emissionen der gesamten Pkw-Flotte nicht mehr existiert.
