Prema planovima, gasovod Nabucco dužine 3.300km išao bi kroz Tursku, Bugarsku, Rumuniju i Mađarsku do Austrije i prenosio bi, kad počne raditi, 30 milijardi kubnih metara godišnje kaspijskog prirodnog gasa za Evropu.
According to plans, the 3,300km Nabucco pipeline would run through Turkey, Bulgaria, Romania and Hungary to Austria, carrying 30 billion cubic metres of Caspian natural gas to Europe annually, once it becomes fully operational.
