• Energy consumption
• Sustainable tunnelling
• Landscape integration
• Labeling policy

In the last years, besides traffic safety, two aspects of road tunnels have become really critical: energy consumption of the lighting installations and landscape integration of the portal gate. However, both aspects have been considered from different perspectives, and their development and advances seem to follow separate paths. In this work, energy consumption and landscape integration, together with the cost of portal construction, are proven to be strongly related when considered from the common framework of sustainability and its implications in a necessary global Policy for road tunnels. Departing from the evaluation of real tunnels in a real highway, three quantitative parameters ranged from 0 to 5 (energy consumption parameter, landscape integration parameter and construction cost parameter) are proposed to build a more general tool, the sustainability vector, that gives account of the degree of sustainability and highlights the necessity of corrective actions when necessary. Depending on the values of its module and director angle, a labeling system ranging from A to D, is proposed for the use of Regulatory Bodies and Public Administrations in matter of tunnel classification and sustainability requirements. According to this system, two of the tubes analyzed reach the "A" labeling, whereas two are "B" and six are "D".
