Substantial progress has been made in putting in place a common transport policy within the European Union, by removing barriers, increasing competition, and improving the quality of service and safety, especially in the road, rail and air transport sectors. However, substantial further efficiency gains could be achieved from further action to create a more fully integrated transport sector. There is at present no comprehensive estimation of the cost of non-Europe in the overall transport sector. However, an assessment is being undertaken by Parliament in the form of a Cost of Non-Europe Report. Preliminary findings indicate that benefits from a further deepening of the single market in transport would amount to at least 3.83 billion euro per year.
