The Future of Sustainable Aviation

The aviation industry has a significant decarbonization challenge. With an estimated 12% of transport-specific emissions attributed to aviation, the industry must take proactive steps to reduce its carbon footprint. Sustainable Aviation Fuels (SAFs) are one of the most promising solutions. SAFs, either biofuels or synfuels, have the potential to revolutionize the industry and allow for a more sustainable future. In this snippet, we’ll discuss the problem, solution, impacts, examples, and CTAs of SAFs to provide a clear understanding of its potential.


The aviation industry is one of the leading contributors to greenhouse gas emissions, responsible for 2-3% of global CO2 emissions. Due to the predicted surge in air travel demand, emissions from aviation are expected to triple by 2050. This presents a daunting challenge for the industry to tackle. We must find sustainable aviation fuels that can work as a short-term solution while other decarbonization technologies are developed.


Sustainable Aviation Fuels (SAFs) are a promising sustainable solution. These fuels can either be biofuels or synfuels, which can be used without modifying existing aircraft. They are also a short-term solution since they have the potential to reduce emissions significantly. Virgin Atlantic's Boeing 787 Dreamliner conducted a landmark flight powered entirely by SAF, from Heathrow Airport to JFK International Airport. This non-conventional fossil-derived fuel offers immense promise in the quest to reduce emissions.


Despite the advancements achieved in SAF production, the industry still has a long way to go. In 2022, around 80 million gallons of SAF were produced globally, tripling the 2021 output. However, this still accounts for less than 0.1% of total global aviation fuel. Although SAFs can cost three to five times more than conventional jet fuel, experts predict that it will dominate long-haul flights by 2040-2050. This will help significantly reduce the carbon footprint of the aviation industry while ensuring its sustainability.


Many companies are investing in SAFs. Some of the prominent ones are World Energy, Neste, Alder Renewables, SkyNRG, Lanza Jet, Air Company, and Fulcrum. These companies are contributing to the production of SAFs while solving the problems around availability and scalability.

SAFs provide a viable short-term solution for the aviation industry to reduce its carbon footprint. We must support and invest in advancements in SAF technology to create a sustainable future for the aviation industry. Moreover, we can contribute by choosing to fly airlines which invest in sustainable aviation fuel usage.

Sustainable Aviation Fuels are among the most promising solutions to the aviation industry's decarbonization challenge. Although SAFs' production is still in its infancy, there are advancements being made, and rewards for the aviation industry to invest in. Companies like World Energy, Neste, and Alder Fuels are paving the way for a sustainable future in aviation. It's up to us, as consumers to support such initiatives, make a sustainable choice, and invest in a better future for the world.
