4. A new rail link to foster environmental protection.

The excavation of the New Lyon-Turin Rail Link is controversial

It is estimated that by 2035 the considerable reduction in heavy truck traffic across the French-Italian Alps will allow to curb greenhouse gases emissions by approximately 1 million tons a year ( freight traffic by rail is considered to be 4-5 times less polluting than freight traffic by road).

The modal shift from road to rail will also help reducing Italy and France dependence on oil which is weighing heavily on their current account balance.
