Concrete is the world’s most widely used material, but making its key ingredient — cement — produces about 8% of global CO₂ emissions.
Researchers in Switzerland have developed an AI model that rapidly suggests low-emission cement recipes, reducing the need for time-consuming lab experiments.
The model can calculate emissions from different materials in milliseconds, helping scientists find more climate-friendly alternatives much faster.
This breakthrough could significantly cut cement’s carbon footprint, but the most promising recipes still need to be tested before they can be used in construction.
