Global Methane Emissions and Mitigation Opportunities

reduce emissions of volatile organic compounds, hazardous air pollutants, and other local air pollutants. This yields health benefits for local populations and workers. Because methane is an important precursor of tropospheric ozone, reducing methane also reduces ozone-related health effects. Methane reduction projects at landfills

3.2 Natural Gas-fired Reciprocating Engines - US EPA

3.2.3.2 Carbon Monoxide and Volatile Organic Compounds - CO and VOC emissions are both products of incomplete combustion. CO results when there is insufficient residence time at high temperature to complete the final step in hydrocarbon oxidation. In reciprocating engines, CO emissions may indicate early quenching of combustion gases on ...
