With a potential to reduce lifecycle carbon emissions by up to 80 %, depending on the feedstock used, sustainable aviation fuels have come under the spotlight. The aviation industry is a hard to abate sector and is currently exploring as well as incorporating sustainable aviation fuels into their airline operations in order to lower carbon emissions and ultimately achieve net zero emissions by 2050. PROCESS Worldwide offers an insight into this interesting space.

Carbon dioxide is a harmful greenhouse gas and one that needs to be addressed immediately to prevent the fears of climate change. Human activities such as setting up diverse industrial facilities as well as developing cars and airplanes for the purpose of transportation, all require fossil fuels to operate which are the primary sources of carbon emissions.

If we single out aviation from this and understand its impact on global CO2 emissions, it will leave you surprised. Aviation accounts for 2.5 % of global CO₂ emissions but it has contributed around 4 % to global warming to date, according to an article by Hannah Ritchie, (Hannah Ritchie (2024) - “What share of global CO₂ emissions come from aviation?” Published online at OurWorldinData.org. Retrieved from: 'https://ourworldindata.org/global-aviation-emissions' [Online Resource]). Therefore, the aviation sector has set out on an ambitious target of achieving net zero emissions by 2050 and the best way to get moving in this direction is to substitute fossil fuels with sustainable fuels i.e. Sustainable Aviation Fuels (SAFs).
