Short summary
This study developed high-resolution maps (100 m × 100 m) showing how much carbon dioxide is emitted from cars and trucks in 20 European cities every hour. Using anonymous GPS signals from vehicles, we tracked traffic CO2 emission patterns throughout the year 2023. The results show that emissions vary significantly between cities and across different days and seasons. This method could help cities monitor on-road emissions in real time and design better strategies to reduce them.
