The report “Factors affecting the CO2 emissions performance of five EU car manufacturers” was prepared for the European Environment Agency (EEA) by EMISIA, as member of the European Topic Centre on Air pollution, Transport, Noise and Industrial pollution (ETC/ATNI).
The scope of the report is to estimate and assess the most important technologies and strategies contributing to the observed CO2 reduction for selected car manufacturers based on new vehicles registered in the time period 2010 to 2018. These reductions can be attributed to both the overall improvement of vehicle energy efficiency as well as to a change in the mix of vehicle models sold in favour of more efficient powertrains/technologies. In particular, car manufacturers are using a broad spectrum of technologies to improve fuel efficiency for their vehicles in response to EU CO2 targets.
