The Ministry of Transport and Sustainable Mobility is the ministerial department of the Government of Spain responsible for national infrastructure and transport policy. Its mandate includes planning, regulating, and developing road, rail, civil aviation, and maritime networks, with an emphasis on sustainable and low-emission transit systems. Tracing its institutional roots to 1847 with the creation of the Secretariat of Public Works—and long known as the Ministry of Development (Fomento)—it adopted its current title in 2023 to reflect a modern focus on environmental transition.
