GREEN MESSAGE

Efforts to publicise the green credentials of the Toyota Mirai in California are being backed with eco-billboard technology that improves the quality of the air.

A total of 37 billboards in Los Angeles and San Francisco have been designed to create almost 2320 square metres of pollution-scrubbing surface which reverses the equivalent of 5285 vehicles-worth of nitrogen dioxide (NOX) emissions per month.

This ‘catalytic converter’ of billboards uses titanium dioxide-coated vinyl to purify the surrounding air.

When oxygen reacts with the energised titanium dioxide catalyst, NOX is converted to nitrate and removed from the air. The light-activated, smog-reducing billboards continue to purify the air as long as light, humidity, airflow and the titanium dioxide coating are present.

Mark Angelacos, advanced technology general manager, Toyota Motor North America, said: “This new campaign delivers Toyota Mirai’s ‘vehicle of change’ message on a medium that lives up to that promise.”
