The 2019 Progress Report on Making the Transition to Zero-Emission Mobility highlights the increasing market share of electrically-chargeable vehicles (ECVs) in the EU, with 2.0% of all cars sold in 2018 being electrically-chargeable, a 3.8% increase in new passenger cars being hybrid electric, and a 0.4% decrease in natural gas-powered cars. However, the report also notes that fuel cell vehicles currently account for a negligible share of total EU car sales. In terms of CO2 emissions, the report shows that in 2017, petrol vehicles became the most sold car type in the EU for the first time since 2009, and that in 2018, new-car CO2 emissions increased by 1.8%. The report also highlights that affordability is a major barrier to consumers, with the market uptake of ECVs being directly correlated to a country's GDP per capita. Only 12 EU countries offer bonus payments or premiums to buyers of ECVs, and these incentives differ greatly across the European Union.
