Types of action funded by CBE JU

CBE JU funds three types of actions:

  • Research and Innovation Actions (RIAs) establish new knowledge or explore the feasibility of a new or improved technology, product, process, service or solution. These may include basic and applied research, technology development and integration, testing, demonstration, and validation on a small-scale prototype, in a laboratory or simulated environment.
  • Innovation Actions (IAs) scale up activities from prototype to product validation and market replication. Flagships, an important and specific type of IAs, in particular deploy a first-of-its-kind innovation on the European market.
  • Coordination and Support Actions (CSAs), among other, structure stakeholder communities, support technological visions and outreach, as well as disseminate and exploit research results.
