SENASA is a reference in environmental-related aeronautical topics and has acquired national and international recognition due to projects on environmental impact, aeronautical noise and studies on emissions and energy efficiency. To carry out this work it has a multidisciplinary team of highly qualified experts, with extensive background and experience.

"SENASA is a reference in environmental-related aeronautical topics and has acquired national and international recognition"

SENASA carries out support work for AESA (Spanish Air Safety Agency) and the National Authority for Meteorological Supervision (ANSMET) in a wide range of activities related to environmental issues.


In addition, SENASA works for the national authority in tasks related to the implementation of the European Emissions Trading System (ETS) for aviation and is part of the Spanish Initiative for the Production and Consumption of Bio-kerosene in Aviation (Bioqueroseno) in line with the global objective Emission reductions and the Clean Skies initiative.


The main projects in which SENASA currently participates are:


Technical Support on EIA (AESA)

SENASA provides technical support services to AESA in the Environmental Impact Assessment of public Infrastructure Projects (aerodromes, heliports and flight fields for ULM) which are competence of AESA as well as any infrastructure for private or restricted use in which the Autonomous Communities do no not have competence and therefore AESA has subsidiarily assumed the competence.


Technical Support on Noise (AESA)

SENASA carries out technical support services for the national authority in the elaboration of reports related to the development of legislation related to noise, in the preparation of reports for monitoring noise-related operational restrictions, in the analysis of environmental requirements for airport certification process and in any task derived from the approval of acoustic aviation easements of airport infrastructures.


Technical Support on ETS (AESA)

SENASA carries out technical support for AESA in the field of Emissions Trading of CO2 (EU-ETS), development of new Global Market Mechanisms, Action Plans for Reducing CO2 Emissions and in the incorporation of alternative fuels in aviation as well as any sustainability requirements.







Flight Path (CE)

SENASA is the Coordinator of the European Commission financed project Coordination of renewable fuel stakeholder strategy in the field of Aviation that aims to update of the European Advanced Biofuels Flightpath. The objective of this project is to identify barriers and solutions to make sustainable alternative fuels a real tool for the decarbonisation of the EU aviation sector. More information at



Since 2013 SENASA has participated actively in the definition of a Carbon Offset and Reduction Scheme for International Aviation (CORSIA). At the 39th Assembly of the International Civil Aviation Organization (ICAO), held in October 2016 in Montreal, the implementation of this scheme was agreed in order to tackle any increase of international aviation’s annual emissions from 2020 levels. Offsetting schemes involve the compensation of emissions produced in a certain sector through the reduction of emissions in other sectors. The logic behind this mechanism is based on the fact that the greenhouse gases (GHGs) produced by aviation can be compensated through reduction, elimination or directly avoiding emissions in other sectors.
SENASA is currently managing the implementation of CORSIA in Spain from 2018. More information at


SENSASA has also participated in the following projects recently:



Since its creation in 2007, the Observatory of Sustainability in Aviation (OBSA) has aimed to be the national reference center for the collection, analysis, evaluation and dissemination of existing information on aviation sustainability considering its dimensions: social, economic and environmental. The Observatory has contributed to sustainability in aviation by actively working on technical projects, international programs such as SESAR or AIRE for the improvement of energy efficiency, in international networks such as ANNA and in consultancy and training projects as well as agreements signed with several public and private entities.



SENASA has promoted and coordinated this project, co-financed by the European Commission, for the commercial development of sustainable aviation biofuels. Its objective was to demonstrate the possibility of using biofuels for commercial aviation in Europe in a sustainable manner. It connects the entire production chain and analyzes the different steps to ensure technical and environmental viability. Visit Itaka web


Core Jet Fuel (CE)

SENASA has participated in this project, which is part of the 7th Research Framework Program of the European Commission, performing tasks of analysis of raw materials and technologies available for the manufacture of alternative fuels for the aeronautical sector.Visit Core Jet Fuel web

Forum AE (CE)

SENASA has participated in the Forum AE project, a project aiming to create a European network of specialists (academia and industry) related to the key issues of aviation emissions. It addresses environmental impacts (air quality and climate change), mitigation solutions (aircraft, engine, operations, alternative fuels) and technical regulation issues (CAEP, local regulations), including standardization, dissemination and policy dialogue.


National emissions inventories

SENASA has collaborated since 2009 with the Ministry for Ecological Transition in the preparation of the Emissions Inventory of the aviation sector, an obligation under the commitments of the European Union and several international conventions on monitoring and reporting of greenhouse gas emissions and other air pollutants at national level.


Madrid-Barajas airport Acoustic analysis (Airbus)

Currently, SENASA collaborates with the AIRBUS Group, ENAIRE, AENA, SA, and the IAG group, in a project to evaluate and identify measures for noise attenuation in the Madrid - Barajas Adolfo Suarez airport, mainly based In PBN (Performance Based Navigation) operations. This study involves the execution of flight simulations for RNP APCH approaches, evaluating together with AENA, S.A. the acoustic improvements derived from a more efficient use of airspace.
