As we navigate the second decade of the 21st century, the term ‘sustainability’ has not only gained popularity but also urgency. Every industry, from fashion to technology, is becoming part of the green revolution, and the airline industry is no exception.

The introduction of Sustainable Aviation Fuel (SAF) is a significant stride towards reducing the carbon footprint of air travel.

SAF is a broad term for non-petroleum based fuels used in aircraft. It’s derived from sustainable resources like natural oils and fats, agricultural residues, and non-fossil CO2. The major attraction is SAF’s capability to reduce carbon emissions by up to 80% compared to conventional jet fuel, contributing massively towards combating climate change.
Airlines worldwide are prioritizing the use of SAF. In February 2021, United Airlines pledged to become 100% green by reducing its greenhouse gas emissions by 100% by 2050. This ambitious goal includes a substantial investment in SAF. This is not an isolated instance. KLM Royal Dutch Airlines operated the world’s first passenger flight using SAF in 2011, and since then, they have been actively promoting and incorporating SAF into their operations.

However, it’s not all smooth sailing for SAF. The cost of production is a significant hurdle. Currently, SAF is approximately 2-4 times more expensive than conventional jet fuel. Supply is another issue. Only 0.1% of global jet fuel supply is made up of SAF, primarily due to production limitations.

Despite these challenges, the future of SAF looks promising. Technological advancements are expected to lower production costs.

Moreover, governmental support could also play a crucial role.

For instance, the Biden administration in the USA has vocalized strong support for clean energy, which could translate into favorable policies for SAF production and usage.

In conclusion, Sustainable Aviation Fuel is paving the way for a greener future in the airline industry. By overcoming cost and supply challenges, we are likely to witness a significant expansion of SAF in the years to come. The journey towards sustainable air travel is airborne already, and with the right tailwinds, we are set to reach new heights.
