About

We believe in a more responsible way of flying. At Estuaire, our mission is to empower aerospace companies to reduce their climate impact.

We collaborate with stakeholders across the aviation industry — including airlines, airports, lessors, and financiers — to address aviation’s role in climate change, which has contributed approximately 4% to anthropogenic global warming. With expertise in non-CO2 emissions and a strong focus on contrail mitigation, we are dedicated to making aviation more sustainable.

Joining Estuaire means stepping into a fast-paced, entrepreneurial environment where you’ll work closely with clients to drive impactful initiatives. If you are motivated to make a real difference and thrive in an early-stage company where much remains to be built, we’d love to hear from you.
