The measures implemented to optimize and manage airspace, promoted by ENAIRE in the national plan, have been fundamental to achieve these results. The analysis of data at key airports such as Adolfo Suárez Madrid-Barajas, Josep Tarradellas Barcelona-El Prat, Palma, Málaga-Costa del Sol and Gran Canaria has made it possible to assess the environmental impact and to adjust operations to minimize emissions. 

In addition, the Observatory has fostered collaboration between pilots and air traffic controllers through visits to air traffic control towers and centers. In 2024, visits were made to ENAIRE's control centers in Madrid, Barcelona and Gran Canaria, and for 2025 additional visits are planned to the control towers of Barcelona, Malaga and Gran Canaria. These initiatives seek to improve mutual understanding and to share experiences which contribute to the safety and efficiency of air operations. 

Since its creation in 2019, the Observatory has accumulated close to 15,000 observations, providing a valuable database to identify best practices and areas for improvement in operational safety and environmental sustainability. Currently, it has the active participation of 36 COPAC chartered pilots and 24 ENAIRE air traffic controllers. By 2025, the incorporation of more pilot-observers and air traffic controllers is foreseen, increasing the capacity for data collection and analysis in the monitoring committees. 

This progress is part of ENAIRE's commitment to environmental sustainability, reflected in its Green Sky Environmental Sustainability Plan, which seeks to deepen measures to achieve greater fuel savings and reduce CO₂ emissions, moving towards environmental responsibility and excellence. 

The Observatory for Safety, Efficiency and Sustainability in Air Operations has demonstrated that, through collaboration and the implementation of best practices, it is possible to achieve a more efficient and environmentally friendly aviation, even in contexts of air traffic growth.
