Eco-billboards ‘purify air’

Toyota Mirai’s customers care about the air – their vehicles emit nothing but water vapour. Now, the fuel cell car’s newest campaign will feature a series of ‘eco-billboards’ that will help Californians breathe even easier.

Tackling nitrogen dioxide

From 03 April to 28 May, 37 billboards in Los Angeles and San Francisco will create 24,960 square feet of pollution-scrubbing surface and reverse the equivalent of 5,285 vehicles worth of nitrogen dioxide (NOx) emissions per month. NOx is a key ingredient in acid rain and smog.

This ‘catalytic converter’ of billboards uses a 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 will continue to purify the air as long as light, humidity, airflow and the titanium dioxide coating are present.

‘When Clear Channel Outdoor Americas brought us the opportunity, we saw it as a perfect match. This new campaign delivers Toyota Mirai’s ‘vehicle of change’ message on a medium that lives up to that promise.’
