Green plants reduce city street pollution, cutting nitrogen dioxide (NO2) by 40% and particulate matter (PM) by 60%. Thomas Pugh and colleagues from Karlsruhe Institute of Technology (Germany) report that green plants can improve urban air quality by removing NO2 and PM pollutants from the air. The study authors propose that cities build plant-covered "green billboards" to increase the amount of foliage, concluding: judicious use of vegetation can create efficient urban pollutant filter, producing rapid and sustained improvements in street level air quality in dense urban areas."
