In this context, sustainability and technological innovation are fundamental pillars to guarantee the future of the sector.
In 2025, Aciturri reaffirmed its commitment to the sustainable development of the aeronautical industry. The company plays an active role as a founding member of Clean Aviation, the European Union's leading public-private initiative for the advancement of low-environmental-impact aeronautical technologies. The initiative's objective is to achieve a net reduction in greenhouse gas (GHG) emissions of at least 30%, as outlined in the Strategic Research and Innovation Agenda for Aviation (SRIA), which will be reviewed and confirmed by the end of 2024. In addition to its involvement in Clean Aviation's governance bodies, Aciturri is actively promoting projects aimed at reducing emissions in the three priority areas identified by the SRIA: hybrid-electric aircraft, ultra-efficient fuel-consumption models, and hydrogen-based propulsion.
Hydrogen has firmly established itself as the predominant alternative to fossil fuels in the industry. Aciturri is promoting projects that aim to develop hydrogen storage and transport solutions, as well as in-flight storage, thereby facilitating the transition towards long-range flights powered by hydrogen.
Within this framework, in 2025, Aciturri continued to lead the H2elios project and to be part of the Newborn consortium, both focused on the development of liquid hydrogen tanks for aeronautical applications.
Similarly, the team has successfully completed the VALORH2 and VITALH2 projects. The first project involved the design, manufacturing, and testing of a type IV hydrogen gas tank at 350 bar. VITAL H2 has successfully completed the manufacturing of a basic demonstrator tank for cryogenic storage of hydrogen or oxygen. In addition, the project has developed computational tools to estimate cryogenic behaviors based on test results.
In addition to the two aforementioned projects, Aciturri completed nine further projects focused on product development and process optimization in areas as diverse as structures for space launchers, manufacturing through additive technologies for RPAs, and the development of aerostructure solutions in thermoplastic materials and thermoset composites for out-of-autoclave curing. They collaborate closely with customers, research centers, universities, and other companies in the sector.
At the same time, the Company has continued to contribute significantly to the development of sustainable mobility. In 2025, Aciturri consolidated its position as a key eVTOL supplier thanks to the trust placed by VERTICAL in the design, engineering and manufacturing of the complete aerostructure of the VX4 eVTOL, which includes the wing, empennage, pylons and fuselage of this fully electric, zero-emission vertical take-off and landing aircraft.
The Company maintains its position as a supplier to Eve Air Mobility, an EMBRAER subsidiary, participating in the development and manufacturing of composite components for the wing of its fully electric vertical take-off and landing aircraft.
Likewise, the manufacture of the first parts for Deutsche Aircraft’s D328ecoTM demonstrator has been launched, an aircraft noted for its efficiency, economy and lower environmental impact, aimed at achieving zero-emission flights.
Aware of the environmental impact of its operations, Aciturri has calculated its carbon footprint since 2016, considering it to be the main indicator. Since then, it has continued to carry out a detailed analysis that enables it to know and calculate direct and indirect emissions, thereby gaining a comprehensive understanding of the scope. Furthermore, since 2023 it has also included, across all the Group’s companies and production plants (apart from Morocco), the so-called indirect activity emissions or Scope 3 emissions, those not directly related to manufacturing.
Aware of these indicators, the impact it has on the communities close to its activity, and aligned with the commitment to reduce CO2 emissions and the Paris Agreement, the Company has a 2024-2050 Decarbonization Plan, established in accordance with the Science Based Targets initiative (SBTi), which includes short- and long-term objectives and has a global scope for all plants.
