Priorities and funded actions

Some Horizon Europe budgets are structured in response to policy ambitions (“destinations”) and deployed through calls for proposals targeting more specific thematic/sector (“Topics”). Thus, your application must be linked to a topic of a call for proposals.

Various categories of projects are eligible: 

  • RIA, Research and Innovation Actions: Basic and applied research / Technology development and adoption / Testing and validation of a prototype in the laboratory ;
  • IA, Innovation Actions: Prototypes, tests, demonstrations, pilot projects, market placement. These actions may include limited R&D activities ;
  • CSA, Coordination and Support Actions: Networking, studies & conferences, communication, studies for new research infrastructures ;
  • MSCA, Marie Skłodowska-Curie Actions / ERC individual grants: Training networks for researchers, Individual grants for experienced researchers, Staff exchange – mobility for researchers and non-scientific staff.

In addition, calls specify the categories of eligible beneficiaries: 

  • Collaborative projects, composed of a coordinator and several partners organisations (consortium) ;
  • Single-beneficiary projects, involving a single organization ;
  • Individual scholarships, open to natural persons in their own name with their home institution.
