Breathe cleaner air right now.

NGVs offer the fastest, most cost-effective path to reducing heavy-duty vehicle emissions

2025

OUR GOAL

Every child in America should awake in a neighborhood with clean air by 2025.  Natural Gas Vehicles can get us there.

THE PROBLEM

Our Air - New

U.S. transit buses now running on CNG or LNG.

Airports operating NGVs in their private fleets or championing policies that encourage use by private fleets.

New refuse trucks running on natural gas.

Too many breathe unhealthy air daily

Close to 120 million people – nearly 36% of all Americans – live in places with failing grades for unhealthy levels of ozone or particle pollution. Breathing that air increases the risk of asthma, lung cancer, and heart disease.

Despite decades of progress on cleaning up sources of air pollution, more than 40% of Americans—over 137 million people—are living in places with 'very unhealthy' and 'hazardous' air quality.

Asthma Rates

25 million Americans (1 in 12) suffer from asthma. That's about 8% of the population.

In 2007, asthma cost the U.S. about $56 billion in medical costs, lost school/work days and early death.

THE SOURCE

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 (HDVs) account for upwards of 50 percent of America’s smog-precursor emissions.

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

NGV emissions during deputy cycles (slower speeds, idling, stop and go traffic) decrease while diesel deputy cycle emissions increase.

FUEL

Natural Gas and Renewable Natural Gas provide CO2 and greenhouse gas emission reductions compared to diesel:

Renewable-Natural-Gas-v4

* Dependent upon RNG source. Reductions of 45% (landfill) up to 582% (dairy) compared to diesel; values based on CARB LCFS program data under CA-GREET 3.0.

NATURAL GAS vs. ELECTRIC

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.
