Azores Airlines improves fuel efficiency in 2025

In 2025, the Azores Airlines fleet made significant improvements to its fuel consumption efficiency. Compared to 2024, operations recorded a 2.96% reduction in consumption per flight hour, equating to 67.6 kg less per block hour*. Over the full year, this equates to savings of 2,276 tonnes of jet fuel, valued at approximately 1.82 million dollars (800 USD per tonne), equivalent to the fuel needed for around 380 flights between Lisbon and Ponta Delgada. This performance also prevented the emission of 7,192 tonnes of CO₂.

This result reflects the consistent application of operational practices aligned with international industry standards. These include optimising flight planning; improving dispatch and operational control; making ground operations more efficient; enhancing flight operations; adopting procedures by technical teams throughout all phases of flight; and reducing ground and air delays wherever possible. It is a joint effort involving multiple teams and coordination between departments.

The airline is planning further actions to implement optimisation procedures that will help it to meet its environmental goals, including reducing emissions per passenger (gCO₂/PKM) by 55% by 2030, using 2005 as the reference year.

Programmes and certifications support this trajectory.

To ensure a robust, aviation-specific environmental management system, the group's airlines joined the IATA Environmental Assessment (IEnvA) programme. In 2023, Azores Airlines and SATA Air Açores became the first Portuguese airlines to achieve this recognition.

This certification was renewed in 2025, expanding its scope to include maintenance and engineering, alongside the renewal of the IOSA (International Operational Safety Audit) registration. This attests to compliance with rigorous international operational safety standards, as well as demonstrating the maturity of internal processes.

The SATA Group is also part of the Alliance for Zero-Emission Aviation (AZEA) and participates in ICAO's CORSIA programme and the EU ETS under the European Commission. The SATA Group also joined the Aviation Sustainability Alliance (ASA), an initiative framed within the National Aviation Decarbonization Roadmap (RONDA).
