Co-funding varies according to the call and sector from 15% to 60% for project feasibility studies.

The Connecting Europe Facility (CEF) supports the development of high-performing, sustainable, and efficiently interconnected trans-European networks in the fields of transport, energy, and digital services.

In addition to grants, the CEF provides financial support to projects through innovative financial instruments such as guarantees and project bonds. These instruments create significant leverage in the use of the EU budget and act as catalysts to attract further funding from the private sector and other public actors.
