Toyota’s ‘Eco-Billboards’ clean the air around them

In a new advertising campaign for its hydrogen fueled Mirai model, Toyota unveiled an eco-billboard in California that actively reduces the smog. From April 2 through May 28, 37 billboards scattered around Los Angeles and San Francisco will reverse the equivalent of 5,285 vehicles worth of nitrogen dioxide emissions per month. The chemical compound is a harmful pollutant and a key ingredient in acid rain and smog.
The air-cleaning billboards use a titanium dioxide coated vinyl to purify the surrounding air. When oxygen reacts with the energized titanium dioxide catalyst, nitrogen dioxide is converted to nitrate and removed from the air.
“This new campaign delivers Toyota Mirai’s ‘vehicle of change’ message on a medium that lives up to that promise,” said Mark Angelacos, Toyota’s advanced technology general manager.
