Correction to Life-Cycle Greenhouse Gas Emissions of Shale Gas, Natural Gas, Coal, and Petroleum Andrew Burnham,* Jeongwoo Han, Corrie E. Clark, Michael Wang, Jennifer B. Dunn, and Ignasi Palou-Rivera Environ. Sci. Technol. 46, (2), 619−627. DOI: 10.0121/es201942m S Supporting Information *

A new Supporting Information file has been provided that corrects Table S1, as the units for well completions, workovers, and liquid unloadings were changed in the text from “metric ton CH4” to “metric ton NG” to highlight that EPA incorrectly labeled these in their Subpart W report. However, the calculations in our report already accounted for this issue and therefore are not changed in this correction. Correspondingly on page 621 of our article, the units for completions/ workovers, “177 t of CH4”, and unloadings, “11 t of CH4” and “26.7 t of CH4”, should be “t of NG”.
