Respect for the environment, a shared commitment

 

The environment and respect for ecology are central to the Mont Blanc Tunnel’s concerns.

On a daily basis, checks are carried out on the quality of the air inside and outside the tunnel.

Outside organizations are in charge of the daily check on pollution levels in the tunnel and along the access routes.

Air quality, dust concentration and noise are monitored by competent organizations from the two regions, in order to guarantee to the inhabitants of the two valleys and users of the tunnel that the limits set by European standards are being adhered to.

Transit of heavy vehicles classified in pollution category “Euro 0” is prohibited.

“Euro 1” vehicles have to pay a higher toll than that applied to “Euro 2, 3, 4 and 5” vehicles, that are fitted with more modern anti-pollution devices.

This commercial policy, together with the progressive renewal of Europe’s vehicle fleet, makes a concrete contribution to reducing pollution in the Tunnel and along the access routes: today, Euro 1 vehicles are only a very small percentage (about 1.1% of the lorries passing through the Mont Blanc Tunnel) while, before the closure in March 1999, that type of vehicle, together with the Euro 0 type, represented almost the whole of the vehicle fleet travelling along the route.
