One of the murals was painted on Karaka Street in Auckland last month, and Converse claims the eye-catching 195 square metre artwork is the equivalent of planting 182 trees. In a press release announcing the Auckland mural, Converse said:"The mural has been installed with a unique photocatalytic paint that absorbs air pollutants as a plant would. "Globally, Converse has activated these sustainable murals from Singapore to Sao Paolo and planted the equivalent of 9,036 trees and counting." While some of the claims are true, if a little overstated, the claims about carbon dioxide are the most misleading. Hodgkiss said the paint does not absorb enough CO2 during the drying process to make up for the CO2 used when the paint is made.
