Interreg is a key European Union (EU) instruments that strengthens cooperation between regions and countries within the EU. As part of the EU’s Cohesion Policy, Interreg plays a vital role in promoting regional development, cohesion, and reducing economic disparities. For the 2021-2027 period, Interreg is focused on addressing current challenges like climate change, digital transformation, and social inclusion.


Interreg’s Evolution and Expansion

Discover the growth of the EU’s Interreg program since 1990

Starting in 1990 as a Community Initiative with a EUR 1 billion budget, Interreg focused on cross-border cooperation. Over time, it expanded to include transnational and interregional cooperation.

Interreg 2021-2027:

The current period’s EUR 10 billion budget highlights Interreg’s evolution, featuring reinforced cooperation with partner countries via Interreg IPA and Interreg NEXT, and a dedicated strand for EU outermost regions and neighboring countries.
