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
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.
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.

Americans live with unhealthy air
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.
125 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.

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.
In 2009, 1 in 6 African-American children had asthma, the top rate amongst all racial/ethnic groups.

25 million Americans (1 in 12) suffer from asthma. That's about 8% of the population.
More than 18 million Americans live in counties that got an “F” for all three air pollution measures.
In 2007, asthma cost the U.S. about $56 billion in medical costs, lost school/work days and early death.
People of color are 3.7 times more likely than white people to live in a county with three failing air quality grades.

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.

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

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:
* 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.
