Methane (CH4) is the second largest source of greenhouse gas emitted in the US. In 2013, CH4 accounted for about 10 percent of all US greenhouse gas emissions from human activities. Methane’s half-life in the atmosphere is much shorter than that of carbon dioxide (CO2); however, it is significantly more efficient at trapping radiation. Pound for pound, the comparative impact of CH4 on climate change is 25 times greater than that of CO2 during a 100-year period.
One area responsible for contributing to the increase in CH4 is leaking equipment in the oil and gas sector. A major contributor to this leakage is valves that leak CH4 and sub-derivatives called volatile organic compounds (VOC) from the gland.
