    Assessing the Impact of Shared L-Category Electric Vehicles in six European cities

    This paper proposes a methodology to assess the impact of shared light electric vehicles in urban areas. The proposed approach consists of the comparison between the emissions and costs of travels carried out by traditional cars fueled by gasoline and those performed by shared light electric vehicles in six European cities (Bari, Berlin, Genoa, Malaga, Rome and Trikala) located in four different European countries (Italy, Germany, Spain and Greece). Based on the number of kilometers traveled and a set of conversion factors, the environmental impact and the cost of fuel/electricity are assessed for the two transport modes. Furthermore, the paper proposes a methodology to create a geographical scaled up scenario that allows to evaluate emissions and costs in case of an increased use of shared electric vehicles. The data analyzed revealed that the travel time of L-category electric vehicles might be longer compared to cars. Furthermore, by replacing car trips with L-category electric vehicles, CO 2 emissions could decrease of more than 70% in one year, thus reducing about 6, 082 kg of CO 2 emissions

    The present study analyses historical trends (1862-2009) in six variables assessing demographic dynamics in Italy compared with two indicators of forest expansion with the aim to verify the temporal coherence between population and forest transitions at the country scale. The study develops an exploratory data analysis based on principal component analysis, hierarchical and non-hierarchical clustering, non- parametric statistics identifying three time intervals (1862-1920, 1921- 1975, 1976-2009) with homogeneous characteristics in both population and forest attributes. Different relationships (positive linear, negative linear and curvilinear) were found between the studied variables indicating divergent demographic and environmental time patterns during 1862- 2009. The paper provides an empirical assessment of the population- environment nexus in Italy
