If we believe environmental activist claims that carbon monoxide, nitrogen oxides, sulfur dioxide, mercury, and particulate emissions to say nothing of global warming and carbon dioxide emissions are so bad for human health, natural gas production should be a no-brainer.
FORBES: The Sierra Club Fails An Environmental Consistency Test
Fuel cells offer several advantages: they do not have moving parts and there is no burning involved, so there are negligible emissions of environmentally harmful gases like nitrogen, sulfur oxide and carbon monoxide.
The latter include health-damaging and smog-forming airborne pollutants like hydrocarbons, nitrogen oxide, particulate matter, carbon monoxide and formaldehyde, as well as greenhouse gases that contribute to climate change, like carbon dioxide, nitrous oxide, methane and other compounds.
The researchers examined the prevailing inspection system called On-Board Diagnostics II (OBD-II), which tests for excessive carbon monoxide, hydrocarbons, and nitrogen oxides, and also checks the power-train systems for problems that might eventually lead to elevated emissions levels.

Water-ice covers Charon, while Pluto's surface is predominantly nitrogen frost with traces of methane and carbon monoxide ices.
For important pollutants monitored by the EPA, natural gas power cuts carbon monoxide emissions by 81%, nitrogen oxide emissions by 80%, sulfur dioxide emissions by 99%, mercury emissions by 100%, and particulates by 99%.

Automakers already strip lots of other pollutants from cars, such as the nitrogen oxides that contribute to smog, and carbon monoxide, which is poisonous.
Carbon monoxide emissions would go down by 9%, nitrogen oxide emissions by 7%.
Natural gas power emits merely 20% of the carbon monoxide of coal power, 20% of the nitrogen oxides of coal power, less than 1% of the sulfur dioxide of coal power, less than 1% of the particulate matter of coal power and less than 1% of the mercury of coal power.
Also, the cleaner burning fuel reduces combustion byproducts over petroleum and diesel, cutting carbon monoxide emissions by an estimated 90%-97%, and nitrogen dioxide emissions by 35%-60%.

These include the exhaust gases such as nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO).
