On 25 September, we’re wrapping up Code for Earth 2025 with a full day of demos, reflections, and climate tech in action. While the event in Bonn is for participants and mentors only, everyone’s invited to join the livestream. Don’t miss it — this is where the coding phase goes public.
Catch a behind-the-scenes look at how Code for Earth teams are transforming climate and weather data into real tools. Two live sessions featuring project demos, fresh ideas, and honest talk on what it takes to build for impact — all in 90 minutes.
Code for Earth is an innovation programme run by the European Centre for Medium-Range Weather Forecasts (ECMWF). Its aim is to drive innovation and open source developments in the Earth sciences community – supporting developments in weather, atmosphere, and climate, Copernicus and Destination Earth (DestinE). Learn more about ECMWF, Copernicus Climate Change Service (C3S), Copernicus Atmosphere Monitoring Service (CAMS) and DestinE.
Since 2018, each summer, selected developer teams work together with experienced mentors from ECMWF and partner organisations on innovative projects. These projects are related to the broad scope of activities at ECMWF, including data science, weather, climate or other earth sciences, visualisation and more.
to develop unique joint challenges, which serve not only as a call to action for problem-solvers but also as a testament to the power of collaboration
