Low methane leakage from gas pipelines

摘要: Using natural gas for fuel releases less carbon dioxide per unit of energy produced than burning oil or coal, but its production and transport are accompanied by emissions methane, which is a much more potent greenhouse in the short term. This calls into question whether climate forcing could be reduced switching from coal to gas. We have made measurements Russia along world's largest gas-transport system find that methane leakage region 1.4%, considerably expected comparable systems United States. Our calculations indicate using preference other fossil fuels useful term mitigating change.
