Los Angeles artist Hilja Keading’s Carbon Monoxide is a Lethal Gas was a billboard project that addressed the pollution and health hazards created by automobile exhaust, and as such, called for greater utilization of public transportation.

The image, a young girl holding a cloth to her face juxtaposed with bumper-to-bumper traffic, appeared on twenty billboards near highways and streets throughout New York City in the fall of 1990. Carbon Monoxide is a Lethal Gas was co-presented with the MTA Arts for Transit program and TDI.
