Our story
Origins: the European Space Agency (ESA) and the EPFL Space Center.
EcoDeltaV spun out of a multi-year project initiated by the European Space Agency’s Future Launchers Preparatory Program (ESA’s FLPP) and led by the Space Center of the Swiss Federal Institute of Technology in Lausanne (EPFL). Between 2022 and 2025, EPFL Space center’s expertise in space sustainability was distilled into the conception of the Assessment and Comparison Tool (ACT), creating a much-needed means for the space industry to integrate environmental impact assessment into the design process of space missions.
Today: detailed expertise to benefit the space industry.
Today, EcoDeltaV carries the legacy of the EPFL Space Center’ s space sustainability expertise and combines specialized knowledge in launcher emissions from the University of Stuttgart. With this, it has positioned itself uniquely in the space sector by enabling companies to comply with environmental requirements and regulations on sustainability.
Goal: empower the industry with knowledge on their environmental impacts
Tomorrow, EcoDeltaV aims to empower space actors across Europe and the rest of the world; providing them with the necessary knowledge, training and tools to confidently integrate space sustainability best practices in their next designs. The Assessment and Comparison Tool will be a major contributor to this, as it gets further optimised for and fine-tuned to the space industry’s needs.
Vision: adress lifecycle insights in broader design processes.
In the future, EcoDeltaV aims to expand to other complex and capital-intensive industries that are in need of addressing their environmental footprint in the context of growing environmental regulations. EcoDeltaV’s objective is to provide fact-based environmental impact assessments and impact reduction advice during long and complex technological design processes.
About us
Jan-Steffen Fischer
The avid rock climber and launchers’ environmental emissions researcher
As a Phd candidate at the University of Stuttgart, Jan-Steffen is at the forefront of the research on high-atmospheric impacts of launchers and spacecraft during re-entry. His efforts to unite key industry players on the topic has put him in a central role within the research community.
Mathieu Udriot
The dutiful firefighter and systems engineer
After graduating from his Masters at EPFL, Mathieu has grown into an experienced project manager, directing the entire REACT consortium into the successful creation of the Assessment and Comparison Tool (ACT). His involvement with various working groups in the field of space sustainability has granted him notoriety within the key industry players.
Marnix Verkammen
The enthusiastic paraglider and ecodesign consultant
With his MSc thesis at the EPFL Space Center and further work on simplified life cycle assessment, Marnix has grown essential expertise on space systems ecodesign efforts. In parallel, he has been involved with the commercialisation developments after the REACT project efforts and devising the consultancy business model.
Emmanuelle David
The motivated trail runner and industry advisor
Years of experience within the industry – both in hands-on positions at launch campaigns and in higher-level system engineering roles – have given Emmanuelle a birds-eye view of the space sector. Today, she is in an excellent position to advise on space sustainability topics thanks to her leading role at the EPFL Space Center and the Space Sustainability Rating.
