European Research Executive Agency

Under Horizon Europe, the European Commission funds research and innovation developing solutions to address pollution and to guarantee clean and healthy soils, air, fresh and marine water for all. 

Four different calls for proposals have been launched under Horizon Europe: 2024 calls, 2023 calls, 2022 calls (open for proposals submission) and 2021 calls (closed). Scroll down to see their details and status.

2024 calls

There are single-stage and two-stage calls. For the single-stage call for proposals, applicants submit a final proposal by the call deadline. For the two-stage call for proposals, applicants submit an outline application (maximum 10 pages) by the first deadline which will be evaluated against only two award criteria: ‘Excellence’ and ‘Impact’. Successful applicants are invited to submit a full proposal by the second deadline, which will be evaluated against the full set of award criteria. First-stage proposals of two-stage submissions will be evaluated blindly, and applicants may not disclose their identity in Part B of their proposal.
