• Illustration — Benito Mussolini visit Carbonia in 1938 Carbonia was founded on the 18 December 1938 by the Fascist regime. Benito Mussolini ordered the building of the city and was present at its inauguration. The city was built to provide housing for the workforce of the nearby mines. The name Carbonia comes from the Italian word for coal, abundant in the area. Vitale Piga was appointed mayor of Carbonia and served in that capacity from September 28, 1939 to April 24, 1942. Piga authored a book on the coalfields of the Sulcis region titled Il giacimento carbonifero del Sulcis: Carbonia. The city has grown since its founding in 1938 due to immigration from elsewhere on the island and from mainland Italy (in particular from the regions of Veneto, Sicily, Abruzzo, Marche, Basilicata and Campania), reaching about 45,000 residents in 1951. Currently it has a population of over 28,000. Since the closing of the mines in the 1970s, Carbonia has had a high unemployment rate. After the closure of the mines the town's economy was converted to the metallurgical industry. Today most Carbonians are employed in heavy industry, and in the tertiary sector.

According to the Köppen climate classification, Carbonia experiences a hot-summer Mediterranean climate (Csa).
