The US and more than a dozen countries and groups have forged a working group to advance efforts to measure greenhouse gas emissions across the natural gas supply chain to cut global output of the pollution blamed for climate change, the energy department said on Wednesday. The MMRV Working Group aims to advance efforts to measure, monitor, report and verify emissions of methane, carbon dioxide and other greenhouse gases. It seeks to do so for the entire gas supply chain including production, processing, transport, liquefaction, and distribution of the fuel.
