Short summary
This study reports the improvement of air quality in port areas following the implementation of a marine fuel quality regulation. We found that the monitoring of NOx and SO2 concentrations in ship plumes could indicate whether a ship had switched to low-sulphur fuel or not. Results showed that most ships complied with the fuel regulation, which reduced the SO2 emissions by 75 %. After regulation, vanadium, which was used as marker for shipping emissions, decreased significantly (by 97.1 %).
