What is Contrails.org?
Contrails.org brings together leading scientists, technologists, and industry experts to accelerate the scientific research, technological innovations and operational improvements needed to make contrail management a practical reality. We envision a world where intelligent route planning and management eliminates climate warming contrails with near-zero cost.
Our Work is focused across three interconnected areas:
Science: Support strategic research to better model, observe, and measure contrails to improve understanding and de-risk uncertainties.
Technology: Develop open models, tools, and protocols to expand access to contrail resources and build common frameworks for wider deployment.
Implementation: Deploy real-world trials to demonstrate operational feasibility and effectiveness, and resolve system-level hurdles to build pathways for implementation at scale.
Through these efforts, Contrails.org aims to galvanize action towards contrail management. By doing so together, we can create a rapid, scalable and affordable pathway to reduce a significant source of global heating.
Our Team
Contrails.org is a team of scientists, engineers, and industry experts based in the US and UK.

Our Work
See what we're building
We are building open tools and methods to advance a roadmap for contrail avoidance across the aviation industry. Learn more on Github and py.contrails.org.
You can see these tools in action on the Contrails API, Contrail Map and the Contrail Navigator.
