What is it about?
In this paper, we present EVA, a modelling tool designed to evaluate the environmental impact of novel aircraft propulsion systems. The tool allows us to estimate fuel consumption, CO₂, NOx, and other emissions across different engine concepts, such as geared turbofans or constant volume combustors. By simulating both performance and environmental outcomes, EVA helps bridge the gap between innovative engine design and sustainability goals in aviation.

Why is it important?
The aviation sector urgently needs cleaner propulsion systems, but assessing their true environmental trade-offs is complex. What makes this work unique is that EVA provides a holistic framework it doesn’t just analyse fuel efficiency, but also emissions throughout the mission profile. This makes it possible to identify promising technologies early, support decision-making for future aircraft development, and ensure that innovation aligns with climate targets and stricter environmental regulations.
Perspectives
Working on this article was especially rewarding because it combined technical rigour with a broader vision for sustainability. For me, the most exciting part was seeing how EVA can turn theoretical engine concepts into concrete environmental insights. I hope this work inspires both engineers and policymakers to use tools like EVA, ensuring that the next generation of propulsion systems are not only efficient but also truly sustainable.
