Aviation is a dynamic, economically crucial and socially essential industry. However, the aviation sector is responsible for up to 3% of the global man-made carbon dioxide emissions. To decrease the sector's contribution to global warming, SkyNRG - founded by KLM, Spring Associates and Argos Oil - has developed a sustainable jet fuel. The fuel is produced with Hydro-processed Esters and Fatty Acids (HEFA) technology. Compared to fossil jet fuel, SkyNRG's sustainable jet fuel offers up to 80% reduction in CO2 emissions. In the end, this development could have the potential to lower the sector's dependency on fossil fuels and reduce price volatility.
