Pro Danube International (PDI) acts as network of private businesses to promote better infrastructure and services which result in a more intensive use of the environmentally friendly inland waterway. PDI adequately represents the “Danube-minded business” in the political debate on transport policy, transport technology and regional development. The association is a driving force in the development of the Danube as a competitive logistics system that does not compensate or duplicate existing initiatives and other professional associations but integrates and strengthens their activities. PDI acts as a competent partner for authorities and administrations by supporting the definition and implementation of policy actions based on the experiences of the private sector.
