Mobility is the key to quality of life and is vital for competitiveness in the European Union. However, transport emissions and pollutants in European highways threaten the human health and natural environment, negatively affecting local environmental quality and making a significant and growing contribution to climate change. The primary goal of E-Highway Project is the establishment of common methodological tools and mechanisms in order to support the evaluation and improvement of environmental performance in highways in both countries towards a “green” transport network. To this end, environmental monitoring and early warning systems (air/water/noise pollution) will be established in both countries in order to support the decision making towards a ‘’green’’ operational performance of highways and the protection of natural environment. The project also foresees development and maintenance of a project website, dissemination events and material, mass media actions and two seminars.
