Electric vehicles as a proportion of the total fleet

LPG cars dominate the alternative-fuel passenger car fleet. The number of LPG passenger cars almost doubled between 2005 and 2015, reaching 10 million vehicles in 2015. Poland and Italy are the leading countries in the EU-28 with 2.6 million and 2.4 million cars respectively. LPG vehicles account for about 4.3 % of the overall passenger car fleet in the EEA-33. This figure has remained rather constant over the last five years. Registrations of new LPG passenger cars peaked in 2009 at 3.6 % of new registrations, while alternative fuelled car registrations accounted for 3.75 % of of total registrations in the same year. After a sharp decrease following the economic recession, registrations of new LPG vehicles have remained broadly constant. By way of contrast, sales of electric and hybrid vehicles have increased rapidly in recent years and together outsold LPG vehicles by more than a third in 2015. 

The number of natural gas (NG) passenger cars almost tripled between 2005 and 2015. However, they still represent just 1.3 % of the total passenger car fleet. The number of NG passenger cars is only significant in Italy and the United Kingdom (about one million), with only small numbers (a few thousand) to  be found in other EU Member States. The registration of new NG cars shows an increasing trend over the same period, although as a proportion of total new registrations (0.5 %) their number remains low.

The pollutant emissions of properly adjusted LPG and NG vehicles should differ little from petrol vehicles. This is because all three fuels generally contain the same families of chemicals (paraffinic hydrocarbons — petrol also contains aromatics) and because the spark ignition combustion process is similar for both fuels. Only methane (CH₄) emissions from NG vehicles are substantially higher than petrol, as the fuel as such is 90 % methane, which is relatively difficult to ignite in cold areas within the combustion chamber.

LPG has approximately 80 % of the energy content of petrol per litre, while the volumetric energy content of NG ranges from 5 times less than that of petrol for compressed natural gas to 1.8 times less for liquefied natural gas. Despite the energy content disadvantage, both alternative fuels are considered to be promising fuels for the future, mainly because of their widespread availability and alternative energy pathway to oil, as well as the low CO₂ yield per unit of energy delivered.

Hybrid vehicles are not always distinguished from conventional petrol and diesel vehicles in official statistics and hence only some estimates of their numbers can be made. While in 2001, only two hybrid vehicle models were available in the EU, and only about 2 000 were sold, more than 30 hybrid models are now on sale and around 130 000 were sold in 2015. However, hybrid vehicles make up only 0.9 % of new vehicle sales in the EU.

Electric cars are slowly penetrating the EU market. These include battery electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV) and electric vehicles with a range extender (REEV). Despite their small numbers (about 268 000) and their small market share (about 0.11 % of the total passenger car fleet), the number of electric car new registrations in the EU has been increasing steadily over the last years. Sales of BEVs increased by 49 % in 2015 compared with 2014, which continues an increasing trend from 2008. France tops the rankings with 17 660 BEVs sold in 2015, followed by Germany with 12 375, a considerable increase compared with 2014 in both countries. Outside the EU, around 22.5 % of all new cars sold in Norway during 2015 were electric (including PHEVs and BEVs). Among EEA member countries, this makes Norway a leading market for electric vehicles in terms of market share. In addition to BEVs an increasing number of PHEV and REEV vehicles (112 365 petrol and 14 580 diesel) are registered in the EU-28. However, collectively, electric vehicles account for just 0.4 % of total new registrations in the EU-28. Most countries in Europe offer financial incentives such as tax reductions and exemptions for electrically chargeable vehicles. Such incentives can include, for example, exemptions from one-off purchase tax (making the cost comparable with conventional vehicles), VAT exemption, use of bus lanes etc.

Compared with passenger cars, the percentage of alternative-fuel light commercial vehicles and buses is low, with numbers around 1.7 % of the total LCV fleet and 2 % of the bus fleet respectively.

NG buses show an increasing trend over the years, however they only accounted for about 1 % of the total bus fleet in 2015. The numbers of LPG and electric (mainly trolleys) buses are much lower and have remained rather constant over the last 4-5 years. France, Germany, Italy, Sweden and Turkey are the only countries with significant numbers (i.e. above 600) of NG buses.

Numbers of LPG light commercial vehicles (LCVs) continue to increase, but they only account for about 1.2 % of the total LCV fleet, whereas the number of NG LCVs is much smaller at about 0.5 %. Poland is the only country with a significant number of LPG LCVs (around 200 000) and Italy has the highest number of NG LCVs (about 99 000). At slightly above 1.4 % over the last three years (2013–2015), the registration of new alternative-fuel LCVs remains low.
