Construction equipment is a leading contributor to dangerous diesel pollution. According to the US EPA Clean Air Act Advisory Committee, “A single bulldozer engine can emit as much particulate matter as more than 500 cars.” As diesel exhaust carries carcinogens, soot (scientifically referred to as “fine particulate matter”) and ozone smog-forming compounds, diesel-powered construction equipment leaves our society more susceptible to asthma attacks, strokes, lung cancer, heart attacks and premature deaths.
