The Southern Gas Corridor (SGC) is a 3,500-kilometre network of three pipelines: the South Caucasus Pipeline (SCP), Trans- Anatolian Pipeline (TANAP) and Trans-Adriatic Pipeline (TAP). The SGC’s implementation seeks to satisfy the EU’s strategic imperative, following disruptions of gas supplies from Russia via the Ukraine transit route in 2006 and 2009, to access new sources of gas in the Middle East and the Caspian regions. This research note aims to outline the benefits of this cross-border project for Southeast Europe and shed light on options for its expansion, as well as its role in the decarbonization of the European gas sector.
