Work Programme 2025-2027 adopted
The European Commission has adopted the new Work Programme for the Interregional Innovation Investments (I3) Instrument for 2025-2027, allocating €176 million. The next calls are planned to open in May and October 2025

What is the I3 Instrument
The Interregional Innovation Investments (I3) Instrument, under the European Regional and Development Fund (ERDF), supports interregional innovation projects in their scale-up and commercialisation phases. It helps overcome regulatory and market barriers, bringing projects to investment level.
Through Smart Specialisation and interregional collaboration, I3 Instrument strengthens regional ecosystems, fosters sustainable investment connections, and accelerates market uptake of research results.

Regional Innovation Valleys
The Regional Innovation Valleys (RIVs) (RIVs) initiative, part of the New European Innovation Agenda,connects regions across the EU, including those with lower innovation performance, by leveraging strategic regional strengths in line with smart specialisation strategies and EU priorities.
The European Commission allocated EUR 122 million from Horizon Europe (European Innovation Ecosystems) and the European Regional Development Fund (I3 Instrument).
In 2023, EISMEA received 57 proposals (49 under the I3 Instrument and 8 under European Innovation Ecosystems) and selected 15 projects for funding ( 10 under I3 Instrument and 5 under the EIE)
