Super-emitter observations vs. reported emissions - 2020 upstream operator methane intensities 

A novel flyover campaign attributed measurement-based methane intensities to several of the largest upstream operators in the Permian Basin. We compared this to the operators' reported methane emissions over the same area.

Operators Methane intensity (%) reported to the EPA is calculated using publicly available GHGRP Subpart W information, and following the One Future Protocol and reported gas production. Aerial measurement data taken from Benjamin Hmiel et al 2023 Environ. Res. Lett. 18 024029
