Interreg

Interreg is a series of programmes to stimulate cooperation between regions in and out of the European Union (EU), funded by the European Regional Development Fund. The first Interreg started in 1989. Interreg IV covered the period 2007–2013. Interreg V (2014–2020) covers all 27 EU member states, the EFTA countries (Norway, Switzerland, Iceland, Liechtenstein), six accession countries and 18 neighbouring countries. It has a budget of EUR 10.1 billion, which represents 2.8% of the total of the European Cohesion Policy budget. Since the non EU countries don't pay EU membership fee, they contribute directly to Interreg, not through ERDF.

Interreg is designed to stimulate cooperation between member states of the European Union on different levels. One of its main targets is to diminish the influence of national borders in favor of equal economic, social and cultural development of the whole territory of the European Union.^{[citation needed]}

The Interreg goal is designed to strengthen economic, social and territorial cohesion throughout Europe, by fostering the balanced development of the continent through cross-border, transnational and inter-regional cooperation. Special emphasis has been placed on integrating remote regions with those that share external borders with the candidate countries.

Interreg was launched as Interreg I for the programming period 1989–1993 (budget EUR 1.1 billion), and continued as Interreg II for the subsequent period 1994–1999. It moved on to Interreg III for the period 2000–2006. Projects from that closed by the end of 2008. Interreg IV covered the years 2007–2013. Interreg V operated in the period from 2014 through 2020. Interreg VI is currently operational, from 2021 until 2027.

Interreg differs from the majority of Cohesion Policy programmes in one important respect: it involves a collaboration among authorities of two or more Member States. Interreg measures are not only required to demonstrate a positive impact on the development on either side of the border but their design and, possibly, their implementation must be carried out on a common cross-border basis.

Once the Operational Programmes have been approved by the European Commission, the implementation of the programmes is co-ordinated by steering committees, which consist of representatives of the authorities responsible for Cohesion Policy measures in each member state. These can be both central state agencies and regional agencies. Like almost all Cohesion Policy measures, Interreg projects require co-funding to be provided by Member States, regional authorities or the project leaders themselves. The amount of co-funding required differs by region, ranging from 50% down to 0% in the poorest regions.

The final beneficiaries of Interreg funds are usually public authorities, interest associations and non-profit organisations, such as chambers of commerce, employer organisations, unions or research institutes. Under Interreg IV, private firms are only eligible if they apply through a consortium of several firms; in previous programme periods, they were not eligible at all.

Interreg is made up of three strands: Interreg A, Interreg B and Interreg C. They are described in more detail below.
