According to the Regulation (EC) No 1159/2000 structural Fund assistance (ESF, ERDF, etc) must be accompanied by publicity measures which, with the aim of transparency, inform potential and final beneficiaries of the possibilities offered by the Funds and inform the general public about the role played by the European Union in cooperation with the Member States in this area.

The Community support frameworks (CSF’s), operational programmes (OP’s), single programming documents (SPD’s) and Community Initiative programmes (CIP’s) must provide for a communication plan as a framework for information and publicity measures.

Such schemes (e.g. billboards, commemorative plaques, posters, information and communication material and information events) are the responsibility of the authority managing the programme. At Community level the Commission will encourage exchanges of experience and the development of informal networks among those responsible for providing information.
