What is sustainability in aviation?
Aviation sustainability is the holistic approach to minimising the environmental impact of the aviation industry while ensuring its long-term viability.
It encompasses efforts to reduce carbon emissions through advancements in technology, such as biofuels (as sustainable aviation fuel), hybrid, electric or hydrogen propulsion. Improved aircraft design and operational efficiency, coupled with the use of lightweight materials, all contribute to limiting the impact of air mobility on our planet.
Aviation sustainability also includes all the initiatives implemented by a company to reduce the impact of its operational activities: preserving natural resources and protecting biodiversity, ensuring proper waste management, reducing energy and water consumption, etc.
Beyond the environmental perspective, aviation sustainability addresses social and economic aspects, emphasising fair labour practices, community support, and diversity in the workforce. While airlines and aerospace companies are increasingly adopting sustainable practices, government regulations and international agreements are instrumental in shaping the industry’s sustainability initiatives.
Reducing carbon emissions is essential; however, we must at the same time ensure that essential air connections remain affordable and accessible for all. Connectivity is more than just a convenience; it is essential for economic development, fostering social bonds, and facilitating cultural interactions. Enhancing regional connectivity plays a critical role in ensuring that even remote areas remain integrated into the broader economic and social fabric.
Ultimately, aviation sustainability requires collaboration and innovation to balance the growing demand for air travel with environmental and societal considerations.
Why is sustainability in aviation important?
Sustainability in aviation is essential to minimise the environmental impact of the industry and ensure that all communities, no matter where they are in the world and no matter how remote, continue to have access to all the benefits of a connected world.
By reducing carbon emissions, optimising resource use, and encouraging responsible practices while preserving strong connections between communities, the aviation industry can play a pivotal role in combating climate change and fostering economic and social development. A commitment to sustainable aviation not only meets regulatory standards but also addresses global concerns about resource conservation, ensuring a better future for all.
Global context:
According to both the Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA), air transport represented over 2% of global greenhouse gas emissions in 2022 and, more specifically, 12% of global transport sector emissions in 2018 (United Nations, Climate Change Fact Sheet). For that same year, the International Council on Clean Transportation (ICCT) reported that 60% of CO2 emissions came from international operations and 40% from domestic services. A 2021 study by Euro Control showed that short-haul flights (up to 1,500 km) represent 25% of CO2 emissions worldwide, based on total departure numbers.
Decarbonising aviation: The way towards sustainable regional aviation
In September 2021, the Air Transport Action Group (ATAG) updated its ambition and commitments with the 2021 edition of its ATAG Waypoint 2050 report. This adjustment reflects the industry’s increased determination to achieve “net zero carbon emissions” by 2050 and to contribute to the Paris Agreement goals. As an active member of ATAG, ATR is fully committed to this target, as demonstrated by its signature of the Commitment to Fly Net Zero by 2050.
In order to decarbonise the sector, three key areas must be addressed: aircraft efficiency, the use of sustainable energy, and improvements in Air Traffic Management.
In 2022, the International Civil Aviation Organization (ICAO)—the United Nations’ specialised agency for aviation—agreed to strengthen cooperation on the decarbonisation of the aviation sector by adopting the Long-Term Aspirational Goal (LTAG), implemented in addition to the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA, 2019). In 2023, as part of CAAF/3, the aviation sector established a collective goal to start the shift away from fossil fuels by achieving a 5% reduction in CO2 intensity by 2030, facilitated by the use of Sustainable Aviation Fuel (SAF) and Low-Carbon Aviation Fuel (LCAF)*.

Sustainable Aviation Fuel
Sustainable aviation fuel (SAF) is a renewable energy source derived from organic materials, waste, or non fossil feedstocks. Its importance in aviation sustainability lies in its ability to significantly reduce carbon emissions compared to traditional jet fuels. SAF can be seamlessly integrated into existing aircraft and infrastructure, offering a tangible and immediate way to mitigate the environmental impact of air travel. Its use addresses the aviation industry’s commitment to lowering greenhouse gas emissions, promoting lower-impact energy alternatives, and advancing the overall goal of sustainable aviation practices.

Aircraft and Engine Technology
Improving aircraft and engine technologies is crucial to lower the aviation industry’s environmental impact. Enhanced technologies, such as more fuel-efficient engines and advanced materials, reduce carbon emissions, aligning with global efforts to combat climate change. The use of turboprop technology, known for its fuel efficiency and lower emissions compared to traditional jet engines, is particularly effective. Investing in such innovations not only aligns with environmental goals but also positions companies to meet regulatory requirements, reduce operational costs, and enhance their overall competitiveness in an increasingly sustainability focused market.
