A Sustainable Aviation Milestone

The stunning ATR 72-600 of Braathens Regional Airlines is on display at the Farnborough International Airshow 2024 – a fantastic opportunity to take a trip down memory lane and reflect upon the remarkable milestones achieved with this aircraft type and BRA throughout our journey towards 100% SAF. 

At a time when the effects of climate change are ever more evident, the aviation industry faces a pressing challenge: to reduce its environmental impact while maintaining essential connectivity. Sustainable Aviation Fuel (SAF) has emerged as a key solution, and ATR is at the forefront of integrating SAF into its operations. Our objective is clear: to pioneer sustainable regional aviation and significantly reduce carbon emissions. 

The ATR 72-600 is renowned for its exceptional fuel efficiency and lower carbon emissions, burning 45% less fuel and emitting 45% less CO2 compared to similarly sized regional jets. This makes it the ideal platform for integrating SAF, advancing our sustainable aviation goals. Our journey towards sustainability is not just about technological advancements but also about preserving our human need for connection in a way that respects our planet. 

The Swedish Example: A Model for Sustainable Regional Aviation 

Our collaboration with Braathens Regional Airlines (BRA) in Sweden is a testament to the impact of SAF on regional aviation. Since 2018, BRA, ATR, and Neste have worked together towards 100% SAF flights, working on technology, operations, and the SAF supply itself. The Perfect Flight project in 2019 optimised every aspect of a regular commercial ATR flight, including the use of a 50% SAF blend, achieving a 46% reduction in CO2 emissions compared to a standard flight.  

Three years later, in June 2022, we made history. We performed the first-ever commercial flight using 100% SAF in both engines on an ATR 72-600 aircraft operated by BRA, for an expected reduction in CO2 emissions of 80% throughout the entire fuel lifecycle.  

Tangible Benefits of SAF: The Swedish Route 

The regular service by BRA from Stockholm to Angelholm serves around 120 passengers daily across 550 kilometers, a journey that is vital for health, education, business, and family reasons. While alternatives like a six-hour train journey or a nine-hour bus journey exist, the ATR 72-600 enables a 75-minute flight with less CO2 emissions than a sole-occupancy car. When powered 50% by SAF, the CO2 emissions decrease even further from 56kg to 34kg per passenger, showcasing the aircraft’s potential for even greater environmental benefits when 100% SAF flights become the norm.  

The technology is now ready. The ATR 72-600 aircraft is prepared to fly with 100% SAF, and we’re waiting for international fuel standard validation to fully implement these advancements and move towards a more sustainable future.
