STRING urges EU to stay committed to the current TEN-T transport policy

The existing EU regulation on the Trans-European Transport Network (TEN-T) policy should be maintained in its current form. The TEN-T policy is highly beneficial for sustainable development, says Thomas Becker, Managing Director of STRING.
