EPA Queries Studies Claiming Higher Methane Levels Than Agency Estimates

摘要

An EPA climate official is questioning the recent "top down" aerial monitoring studies that suggest that the agency's annual greenhouse gas (GHG) inventory estimates may significantly undercount methane emissions from the oil and gas sector, saying the studies are too premature for EPA to determine whether to re-examine its own estimates. "There's a lot we need to understand better from the top down studies before drawing conclusions that the [agency's] estimates need to be changed," Paul Gunning, climate change division director within EPA's air office, told a May 20 Environmental Law Institute (ELI) teleconference.
