The secretary of state for transport and sustainable mobility is a senior minister of the Spanish Ministry of Transport responsible for assisting the minister in the design and implementation of the government policy on transport infrastructure and in the regulation of land, maritime and air transport.
The secretary of state is appointed by the Monarch on the advice of the minister of transport. Since 29 November 2023, José Antonio Santano Clavero has served as such.
Although there have previously been some Secretariats of State with powers on sustainability and housing, the origin of this secretariat of State dates back to the Royal Decree of 17 December 1993, which created the Secretariat of State for Territorial Policy and Public Works. This secretariat was entrusted with ëthe preparation of the Infrastructure Master Plan, the National Hydrological Plan and the sectoral plans of the different modes of transport that develop the Master Planû.
In 1996, with the change of name of the Ministry of Development, that Secretariat of State was abolished and the secretary of state for infrastructure and transport was created, assuming a very similar structure to the current one. With this reform, the secretary of state loses the powers on housing that the undersecretary of development assumed.
In May 2000, the Secretariat was renamed the Secretariat of State for Infrastructures, recovering the competences in housing that it exercised through the Directorate-General for Housing, Architecture and Urbanism but losing the competences in transportation, which were transferred to the Undersecretariat.
In 2004, the Secretariat of State was renamed the Secretariat of State for Infrastructure and Planning, losing the competencies in housing that become part of the recovered Ministry of Housing. The transportation responsibilities continued separated when the General Secretariat for Transport was created with direct dependence on the Minister. From 2009 to end 2011 it was called Secretariat of State for Planning and Infrastructure.
Due to the economic crisis and the need to cut public spending, in late 2011 a multitude of competencies spread across various bodies were unified in a single one called Secretariat of State for Infrastructure, Transport and Housing, which was developed with a similar structure to that of the secretary of state for infrastructure and transport of 1996.
By Royal Decree 829/2023, of November 20, as was the case in 2004, it lost its powers over housing, which were assumed by the reestablished Ministry of Housing through the Secretariat of State for Housing and Urban Agenda.
The Secretariat of State is composed by three main departments and three secondary departments:
Most of the public enterprises and agencies of the Department of Development are attached to the SETMOS.
