Rethinking Waste Transport
Food transportation produces 18.2 million tonnes of CO2 emissions annually. K-12 schools are the largest source of institutional food waste, yet many organizations lack the tools to rigorously determine the optimal stop ordering for their routes.
pathOS is a student-led project at Cornell University driven by a shared goal: quantify and optimize transportation emissions. What began as a class project is now a platform ready to make a real-world impact by bridging the data gap in Ithaca's Green New Deal.


Making Impact Actionable
We're building a web-based routing tool that optimizes fuel consumption for transportation routes. While standard tools like Google Maps optimize point-to-point routing, pathOS optimizes the order of the stops and accounts for real-world factors like weight accumulation.
Every component is purpose-built for institutional users looking to cut carbon emissions and increase efficiency without impacting operations. Our goal is to reduce stakeholder emissions by 10%, saving thousands of tonnes of CO2 annually.
