How Clean is CNG?
Using CNG means releasing less pollution into the air.
Natural gas vehicles (NGVs) can have a direct, positive impact on America’s air quality and environment – today. NGVs in urban environments are a solution for meeting the Environmental Protection Agency (EPA) non-attainment measures and improving local air quality.
Emissions Reduction in
Real Numbers
NGVs improve air quality through dramatic reductions in emissions, such as:
- Reducing carbon dioxide (CO2) emissions by 20% to 30%
- Reducing carbon monoxide (CO) emissions up to 75%
- Reducing nitrogen oxide (NOx) emissions by approximately 50%
- Reducing up to 95% of particle matter (PM) emissions
- Reducing volatile organic compound (VOCs) emissions by 55%
