America's Natural Gas Alliance (ANGA) and the American Petroleum Institute (API) recently released a study done by URS Corporation showing that methane emissions from natural gas production are at least 53 percent below U.S. EPA's estimates. "The survey is an updated version of data first released in June. It shows that venting of methane into the atmosphere during liquids unloading is 93 percent lower than Environmental Protection Agency (EPA) estimates and that methane emissions from well re-fracturing are 72 percent lower."
