About

WindBorne works to deliver better weather forecasts that reduce emissions and help manage extreme weather. The company aims to save 500 million metric tonnes of carbon per year through better weather-based routing, such as when planes fly with a tailwind or ships sail in lighter seas. Better forecasts also accelerate the adoption of renewables by optimizing use of the electrical grid and reducing the usage of carbon-intensive peaker plants. WindBorne forecasts the precise path and intensity of severe weather, including hurricanes, floods, and tornadoes, predicts heat waves and cold snaps, and informs crisis responders such as firefighters.
