The #1 Source of Urban Emissions? Aging Diesel Fleets

While Heavy-Duty Vehicles only represent a total of 7 percent of all vehicles on America’s roadways, they account for upwards of 50 percent of all smog-precursor emissions and 20 percent of all transportation-related greenhouse gases (GHGs).* Heavy- and medium-duty vehicles are the #1 source of smog in the United States.

In urban areas, our air is unhealthy to breathe with asthma, lung cancer and heart conditions related to air quality on the rise. It is estimated that over 141 million people in the United States live in counties that have unhealthy levels of either ozone or particle pollution.** Four of every 10 Americans live with unhealthy air.

It’s our goal that every child in America should wake up in a neighborhood with clean air by 2025. NGVs offer a fast track for reducing emissions with proven, market-ready, affordable technology. For heavy- and medium-duty applications, NGVs deliver the largest and most cost-efficient reduction in NOx emissions currently available. It’s time to clean up our act! Choose natural gas.

Cleaner. Efficient. Healthier. Breathe Easy with Natural Gas. #CleanFleetMonth
