COST Open Call 2026

A COST Action is an interdisciplinary research network that brings together researchers and innovators to investigate a topic for four years. Open to all science and technology fields, including new and emerging ones, COST Actions are also bottom-up meaning you can propose a network based on your own interests or ideas.
The funding a COST Action receives covers the expenses of networking activities and can be used to fund events, Short-Term Scientific Missions, Training Schools, communication activities, and virtual networking tools. A COST Action has an estimate budget of €150,000 in its first year and on average €180,000 per year for the other three years.
