Boeing , NASA, andUnited Airlines are conducting in-flight tests using 100% sustainable aviation fuel (SAF).- The tests aim to measure the impact of SAF on contrails, non-carbon emissions, and its life cycle climate impact.
- This collaboration reflects a commitment to sustainability and may pave the way for greener aviation.
The ecoDemonstrator Explorer and the role of NASA
The ecoDemonstrator Explorer is an innovative aircraft designed to test and demonstrate new technologies, and it plays a key role in these in-flight tests. It will take to the skies with separate tanks of 100% SAF and conventional jet fuel, allowing the team to compare the effects of each fuel type directly.

Understanding the impact of SAF
The primary aim of these tests is to assess the impact of SAF on contrails and non-carbon emissions. Contrails – the condensation trails left behind by aircraft – can contribute to climate change, and understanding their formation and properties is an important part of reducing aviation’s environmental impact. Non-carbon emissions, such as nitrogen oxides and particulates, also play a role in climate change and can impact air quality around airports.
These tests will also help the team understand the life cycle climate impact of SAF. This includes the greenhouse gas emissions produced during the production, transportation, and use of the fuel. Current estimates suggest that SAF can reduce emissions by up to 85% over its life cycle, making it a promising solution for reducing aviation’s carbon footprint.
Currently, SAF is more expensive than traditional jet fuel but is becoming more cost effective as production costs decrease. Companies like Neste have already taken advantage of this by producing a new type of low carbon fuel called Neste MY Renewable Jet Fuel that is made from waste materials such as cooking oil.
