It takes ten years to grow a tree, but only one day to paint one.
One square meter of Boysen's KNOxOUT smog-eating paint cleans as much nitrogen oxide from the air as a mature tree. To maximize environmental impact of the paint, TBWA\SMP and Boysen decided to paint murals in some of Manila's most traffic-heavy highways to combat CO2 pollutants. The artwork consisted of striking and colorful portraits of rubber ducks, birds, food, toys, and other objects. While a tree takes 10 years to mature enough to clean our air, each KNOxOUT artwork was completed overnight.
