Unaccounted for Gas (UFG) in gas network utilities, particularly methane emissions, is a significant yet often overlooked environmental and financial burden. The increasing concern about environmental issues has placed immense pressure on the oil and gas industry to reduce greenhouse gas (GHG) emissions. Methane, a potent GHG with up to 86 times the Global Warming Potential (GWP) of CO2, has garnered attention at COP26, where 105 countries signed the Global Methane Pledge, committing to a 30% reduction in methane emissions by 2030. It is evident that curbing methane emissions from gas networks holds immense potential for making a substantial impact on global climate change goals.
