1、Gas-fired power methane emissionsA call to Power Methane Emissions 2According to the International Energy Agency(IEA),about 40 percent of total global methane emissions occur naturally from sources such as wetlands,geologic seepage,permafrost,and animal secretions.The remaining 60 percent of global

2、methane emissions are anthropogenic(man-made),and the largest portion of these come from agricultural production such as raising livestock and rice production.Fossil fuel production,transportation,and use account for approximately 20 percent(113 million metric tons)of total global methane emissions,

3、and emissions attributable to gas power are about 3%(17 million metric tons)of the global total.Despite gas power being responsible for a relatively small percentage,GE acknowledges methane emissions reductions across the entire industry are important and should be addressed.Its recognized,however,t

4、hat methane emissions are very difficult to measure and could be significantly higher than estimated.Accurate measurement is a key tool in reducing methane emissions,and improved technology including satellite imagery is being deployed to quantify methane Executive SummaryMethane is a potent greenho

5、use gas,trapping 25X more heat radiated from the earths surface than carbon dioxide.Reducing methane emissions is a powerful and cost-effective way to act on climate change,providing an essential complement to action on reducing CO2SOURCE:IEA METHANE TRACKER 2021emissions more accurately,but actions

6、 can be implemented immediately to contribute to methane emissions abatement.The IEA has identified abatement technologies and practices which could yield significant reductions in methane emissions from the oil&gas sector.They evaluated the potential impact of each to global sector emissions and th
