Interreg 2021-2027

The Interreg 2021-2027 programme allows regional and national authorities to collaborate and define solutions for common challenges, to develop and deliver better policy. On this page you can learn more about the various Interreg programmes.

Interreg programme summary

The European Regional Development Fund (ERDF) aims to strengthen economic, social and territorial cohesion in the European Union by correcting imbalances between its regions. In 2021-2027 it will enable investments in a smarter, greener, more connected and more social Europe that is closer to its citizens.

Interreg is one of the key instruments of the European Union (EU) supporting cooperation across borders through project funding. It aims to jointly tackle common challenges and find shared solutions in fields such as health, environment, research, education, transport, sustainable energy and more. Interreg is funded by ERDF, and €8 billion has been allocated for the 2021-2027 period.

3 types of Interreg programmes

Interreg offers 3 types of programmes to support European territorial cooperation.

  • Cross-border collaborations (60 programmes), supporting cooperation between at least 2 Member states countries that share the same border.
  • Transnational collaborations (14 programmes), supporting cooperation between neighbouring regions from several countries of the EU.
  • Interregional cooperations (4 programmes), supporting projects that can cover the whole of Europe.

Key policy objectives

The Interreg supports the policy objectives (PO) set out by the ERDF and the Cohesion fund:

  1. Smarter Europe- enabling the uptake of innovative technologies across EU
  2. Greener carbon-free Europe- fostering the transitions towards a net-zero carbon economy
  3. More connected Europe– enhancing sustainable transport and cross border mobility
  4. More social and inclusive Europe – ensuring equal opportunities for health, education, and employment of citizens.
  5. Closer to citizens- supporting sustainable creation of urban, rural, and coastal areas

Additionally, the Interreg has two additional specific objectives:

  1. Better cooperation governance- improving the representation of civil society in policies
  2. Safer and more secure Europe – management of mobility migration and border management and support of innovative solutions to today’s safety and security challenges

Not all PO are relevant for each Interreg programme. Each programme decides the priority and challenges relevant to the area and determines the specific objectives accordingly.

General programme information

The average subsidy per project is expected to be €1 to 6 million. Financed projects last approximately between 3 to 5 years. Deadlines may vary per Interreg programme.

Applications should be provided by a consortium. It can be formed by governmental entities, research institutions, companies, regional development agencies, and non-profit organizations. However, the lead partner is usually a non-profit entity.

Projects should aim at overcoming common challenges, addressing one of the programme’s objectives. Interreg usually finances activities of joint strategies development,  demonstration and piloting projects (late TRL stages) to remove boundaries for the adaptation of certain innovative processes/products/services, or knowledge dissemination activities.
