The U.S. government has stopped sharing air quality data gathered from its embassies and consulates, citing funding constraints. This move has sparked concern among scientists and experts who rely on the data to monitor global air quality and improve public health.
The data was used to track fine particulate matter, known as PM2.5, which can cause respiratory diseases and premature death. The World Health Organization estimates that air pollution kills around 7 million people each year. The shutdown of the monitoring program is seen as a significant setback for air quality research and environmental governance.
