Abstract
The main objective of the present study is to analyze the impact of the market share increase of different vehicle technologies in terms of energy consumption and CO2 emissions in the Portuguese mainland region. An extensive characterization of how road vehicle technologies energy consumption and CO2 emissions compare in a full life cycle perspective was attained. The main conclusions are that plug-in hybrid, electric and fuel cell vehicles can have the potential to reduced energy consumption (up to 9%) and CO2 emissions (up to 19%) in a full life cycle analysis.
