Reality Check! Our air is unhealthy to breathe

134 million people in the United States live in counties that have unhealthy levels of either ozone or particle pollution. Breathing that air increases the risk of asthma, lung cancer and heart disease.

Heavy- and medium-duty vehicles are the No. 1 source of smog

While HDVs total 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-duty vehicles – the fastest growing segment of U.S. transportation in terms of energy use and emissions – include:

Short-Haul Trucks
Long-Haul Trucks
Refuse Trucks
School Buses
Transit Buses

74% of Heavy-Duty trucks not certified to latest NOx emission standard. 26% of Heavy-Duty trucks meet NOx emission standard. Replace diesel HDVs & MDVs with Natural Gas Vehicles. NGVs deliver the largest and most cost-effective NOx emissions reductions. In-use testing results of heavy-duty trucks in port applications finds that diesel emits up to 5-times more NOx than certification levels. Natural gas certification levels for NOx are already 10x less than diesel.

It’s more than just the tail pipe … Life-cycle emissions matter too

According to the Union of Concerned Scientists, it takes so much energy to make batteries that Electric Vehicles with a 250-mile range start out life with a carbon footprint 68% higher than a piston-engine car. RNG Vehicles can take the gases already released into our atmosphere from landfills, water waste treatment, farms and food digesters and use it for fuel.
