The Connecting Europe Facility (CEF) supports trans-European networks and infrastructures in three thematic sectors: Energy (where the thematic priorities are: smart grids, intelligent, electricity highways and cross-border CO2 cooperation); Telecommunication (where digital service infrastructures act as a platform on which new industries can create innovative applications); Transport (to promote the modernisation of the European transport infrastructures, the construction of missing links and the removal of bottlenecks).
