The SEA is a preventive instrument permitting the integration of environmental aspects in decision-making on Plans and Programmes, which is implemented by Aena for the environmental evaluation of its airports' directive Master Plans.
Until 2013, legislation on SEA at state level was represented by Law 9/2006, of 28 April, on the assessment of the effects of certain plans and programmes on the environment. As of that year, the applicable rule is Law 21/2013, of 9 December, on environmental assessment.
During the term period of Law 9/2006, the SEA procedure was concluded with the issuing of the “Environmental Report”. As of the entry into force of Law 21/2013, the SEA procedure concludes with the publication of the "Strategic Environmental Statement" by the Ministry.
Also, in the ambit of environmental monitoring, Aena manages compliance with the obligations defined in the corresponding environmental reports, either directly or coordinating with the various units involved, and in all cases is responsible for accrediting compliance with the environmental authority.
The reports obtained in this area, and the reports of compliance, may be found in the airports listed below.
