What is Interreg
Discover what Interreg is, why it matters and how it works.
What Interreg is
Interreg is a key initiative of the European Union that connects countries, regions and communities through a series of funding programmes promoting cross-border, transnational, interregional and outermost regions cooperation. By supporting projects that tackle shared challenges and deliver sustainable solutions, Interreg addresses regional inequalities while promoting economic, social and environmental development across Europe.Why Interreg matters
Since its launch in 1990, Interreg has supported cooperation on issues that impact us all—whether it is protecting the environment, driving innovation or building resilient communities. For the 2021-2027 period, its priorities focus on critical issues such as tackling climate change, advancing digital transformation and fostering social inclusion. With 86 programmes, each covering a specific area, Interreg spans the entire European continent and beyond, playing a key role in promoting regional development and cohesion, and reducing economic disparities.
How Interreg works
Interreg co-funds shared solutions for common challenges that cross borders and require cooperation between organisations from different countries.
To support these shared solutions, Interreg programmes regularly launch calls for projects. Organisations can form a partnership and apply by submitting a project proposal that aligns with the objectives of each call. Each programme has specific rules and requirements for project applications.
Interreg budget 2021-2027
Interreg operates with a seven-year budget. For the 2021-2027 period, the 86 Interreg programmes have a total budget of EUR 8 billion to allocate to projects through calls for projects. Each project receives financial support from Interreg, but organisations applying for funding must contribute some of their own money as well. The amount Interreg covers varies by programme, but it will never exceed 80% of the total project cost.
