The share of alternative fuel vehicles in the vehicle fleet, as measured in this indicator, is defined as the number of vehicles (by vehicle type and fuel) per total number of vehicles (by vehicle type).


Justification for indicator selection

Increasingly tight regulations have resulted in the gradual introduction and promotion of more fuel-efficient, less polluting vehicles. The total stock of alternative fuel vehicles, as well as their new registrations, is an indirect indication of the level of improvement of road transport fuel efficiency and pollutant emissions. The overall objective of this specific indicator is to monitor the penetration of alternative fuel vehicles and hence to be able to estimate progress towards environmental targets.

Indicator definition

The share of alternative fuel vehicles in the vehicle fleet, as measured in this indicator, is defined as the number of vehicles (by vehicle type and fuel) per total number of vehicles (by vehicle type).


The units used in this indicator are the total population of passenger cars, light commercial vehicles and buses by alternative fuel type (LPG, NG and electric).

Policy context and targets

Context description

A number of policies have been adopted that contribute to meeting targets set at EU level. This includes the 20-20-20 policy package, which came into force in 2009. This package sets two targets: an overarching 20 % cut in greenhouse gas emissions in Europe below 1990 levels by 2020; and a 60 % reduction in greenhouse gas emissions from transport below 1990 levels by 2050, as set out in the 2011 Transport White Paper. 

The CO2 emissions targets for new cars and vans contribute to meeting these targetsRegulation 443/2009 sets a CO2 ‘specific emission’ target of 130 grams per kilometre (g/km) by 2015 for new passenger cars sold in the EU. A long-term target of 95 g/km has been set for 2020. Specific targets for vans have also been introduced in Regulation 510/2011. The targets include a first level at 175 g/km, to be phased in from 2014 and to be fully reached in 2017, and a second level of 147 g/km to be reached in 2020.


There are no specific objectives or targets related to the share of the different types of alternative fuel vehicles in the total vehicle fleet. Policy objectives are rather set with respect to the environmental performance of newly registered passenger cars and vans.

Key policy question

Is the share of vehicles powered by alternative fuel in the total vehicle fleet increasing?


Methodology for indicator calculation

The share of alternative fuel vehicles (LPG, NG, electric) in the total vehicle fleet for each vehicle type (passenger cars, light commercial vehicles, buses) is calculated by dividing the number of alternative fuel vehicles by the total fleet for each vehicle type.

Methodology for gap filling

Data gaps are filled either by interpolation, in the case that between reported data are missing, or by using the first (or last) reported value.

Data sources in latest figures


Methodology uncertainty

Not available.

Data sets uncertainty

The data on the stock of alternative fuel vehicles are mostly from statistical sources and hence considered reliable. Data on new registrations are also reliable as they are officially submitted by EU Member States as part of their CO2 reporting obligations. Sibyl and EC4MACS have been used to fill data gaps.

Rationale uncertainty

Not available.
