An overview of CO2 emissions reduction, fuel and technology trends, and market share of new passenger cars in the European Union.

This briefing summarizes the eco-innovation provision, investigates the types and market uptake of approved eco-innovations, and discusses how regulatory developments could affect eco-innovations in the future.

This briefing compares the fleet characteristics and fuel-efficiency technology deployment in China, Europe and the U.S. from 2010 to 2014. In addition, the briefing evaluates the response of the passenger vehicle market in China to the country’s fuel efficiency standards.


Reviews recent research regarding greenhouse gas emissions from the manufacturing of lithium-ion batteries for electric vehicles. We analyze this research in the overall context of life-cycle emissions of electric cars as compared to conventional internal combustion vehicles in Europe. Finally, we discuss the primary drivers of battery manufacturing emissions and how these emissions could be further mitigated in the future.

Der derzeitige Rückgangs des Dieselanteils zieht keine negativen Auswirkungen auf die Erreichbarkeit der Klimaschutzziele nach sich. Vor diesem Hintergrund sollte ein Festhalten an der derzeitigen Subvention von Dieselkraftstoff für Pkw kritisch hinterfragt und eine Angleichung der Steuersätze für Diesel und Benzin in Erwägung gezogen werden.
