Urban air pollution is a serious problem in big cities as it exceeds the safety limits for human health in many cases. To this end, a directive has been passed in Europe whereby the EU must have reduced its greenhouse gas emissions by 80% by the year 2050, in comparison to the 1990 levels. In response to this serious problem, Neolith has joined the environmental conservation efforts with the market launch of a revolutionary treatment for its SKYLINE facade line: PURETI.
