EPA’s Methane Estimates For Oil And Gas Sector Under Investigation
By Phil Mckenna for Inside Climate News - The Environmental Protection Agency's Office of Inspector General will investigate how the agency estimates methane emissions from the oil and gas sector after an environmental group alleged that its emission estimates and regulations are based, in part, on faulty studies. The evaluation, announced Wednesday, will focus on a pair of studies conducted jointly by the University of Texas–Austin and the Environmental Defense Fund in 2013-2014 that found methane emissions to be lower than EPA estimates. The studies, which were done in cooperation with a number of oil and gas companies, were subsequently challenged for allegedly using faulty equipment and underestimating emissions. "This evaluation's objectives are examining the results of and concerns/problems with the 2013 and 2014 emission studies conducted by the Environmental Defense Fund and the University of Texas-Austin," EPA OIG spokesperson Jennifer Kaplan said in an email. The oil and gas sector is the leading source of human-derived methane emissions in the U.S., emitting more than either the agricultural sector or landfills, according to EPA estimates. Regulation of the powerful greenhouse gas has been in dispute since the Trump administration arrived and began rolling back President Barack Obama's efforts to rein in emissions.
