Climate TRACE has released a tool that makes the threat of harmful particulate matter (PM2.5) visible to all. The tool shows the flow of air pollution plumes out of sources that contribute to the climate crisis and into the air that 1.6bn people in more than 2,500 urban areas breathe.

UK air quality: better but not good enough
UK air pollution improved between 2015 and 2024, but is still dangerous too often, research from the University of Reading says in ‘Environmental Science: Atmospheres’. Scientists from the University studied pollution at more than 500 monitoring sites around the UK. They found that two types of pollution got better over the decade: nitrogen dioxide (NO2), which is mainly produced by traffic, fell by 35% on average at monitoring sites; and fine particles called PM2.5, which are small enough to get deep into lungs, dropped by 30%.
