The implementation of the Paris Climate Agreement requires a continuous reduction of greenhouse gas emissions (GHG) by de-fossilization of our energy sources. The transport sector has to achieve near-complete independence of fossil fuels by 2050 an even stricter target than considered so far by the International Energy Agency models. In the long term, battery and fuel cell electric vehicles are essential pillars for decarbonizing the transport sector. Continuous improvement of vehicle efficiency and a strong increase of hybridization and electrification will lead to significant reductions in the required energy for the transport sector. Breakthroughs in battery and fuel cell technology and cost as well as the ramp-up of the charging/filling infrastructure are challenging but most likely manageable. Where locally produced regenerative electrical power is available, electrified transport will be the most likely approach. Nevertheless hybrid and plug-in hybrid passenger cars with an internal combustion engine (ICE) still represent a significant share of the vehicle fleet beyond 2040. In addition to continuous improvement of the vehicles and ICE efficiency, increasing use of CO2- neutral fuels are a strategy for GHG reduction. Biofuels and synthetic fuels based on renewable energies (eFuels) are necessary to significantly reduce GHG emissions of passenger cars. Biofuels and synthetic fuels are even mandatory in other transport sectors such as aviation, navigation and heavy duty commercial transport. In addition to technological improvements - introduced via new vehicles – eFuels have a direct and relevant impact on the overall fleet GHG emissions.
