Participants are invited to submit COST Action proposals contributing to the scientific, technological, economic, cultural or societal knowledge advancement and development of Europe. Multi- and interdisciplinary proposals are encouraged.
The Open Call Action proposal submission, evaluation, selection and approval (SESA) procedure is fully science and technology-driven and will ensure a simple, transparent and competitive proposal evaluation and selection process, reflecting the bottom-up, open and inclusive principles of COST.
Participants planning to submit a proposal for a COST Action will need to refer to the updated COST Open Call proposers guidelines and to the new Open Call Announcement that is available on the Documents and Guidelines page.
All proposals are to be submitted via the dedicated online platform of the COST Association used for grant management, known as e-COST, between 31 July 2026 and 28 October 2026.
