PSE in The Hill: Strong methane rule required to fully realize Clean Power Plan benefits - 8.26.2015
PSE Healthy Energy outlines the important science behind the need for a strengthened EPA Methane Pollution Standard in order to achieve the Administration's greenhouse gas reduction goals in the Clean Power Plan.

Important lessons can be drawn from the UGD experience in the United States. This article explores these considerations and argues that shale gas development policies in the UK and elsewhere should be informed by empirical evidence generated on environmental, public health, and social risks.
U.S. Methane Mitigation 2015: A Review of Climate and Public Health Impacts
PSE Healthy Energy
23 Jan 2015
Jan 14 2015 the U.S. EPA, in response to the Obama Administration's mandate for methane emission reductions, released its plan to cut emissions from the oil and gas industry by 40% - 45% from the 2012 baseline. Response to the proposal has been mixed with many environmental groups immediately applauding the measure before questioning the administration's narrow focus on new emission sources only.
Assessment and risk analysis of casing and cement impairment in oil and gas wells in Pennsylvania, 2000–2012
Anthony R. Ingraffea, Martin T. Wells, Renee L. Santoro, and Seth B. C. Shonkoff
Previous research has demonstrated that proximity to unconventional gas development is associated with elevated concentrations of methane in groundwater aquifers in Pennsylvania. To date, the mechanism of this migration is poorly understood. Our study, which looks at more than 41,000 conventional and unconventional oil and gas wells, helps to explain one possible mechanism of methane migration: compromised structural integrity of casing and cement in oil and gas wells. Additionally, methane, being the primary constituent of natural gas, is a strong greenhouse gas. The identification of mechanisms through which methane may migrate to the atmosphere as fugitive emissions is important to understand the climate dimensions of oil and gas development.

Drilling California: A reality check on the Monterey shale
PSE Healthy Energy/Post Carbon Institute
03 Dec 2013
J. David Hughes
This groundbreaking study is first publicly available empirical analysis of actual oil production data from the Monterey Formation, including from wells that have undergone hydraulic fracturing and acidization. It lays out some of the play's fundamental characteristics compared to other tight oil plays, including geological properties, current production, production potential, and associated environmental issues.
AB 32 Climate Change Scoping Plan First Update: Comments and Recommendations
PSE Healthy Energy
04 Nov 2013
Seth B. Shonkoff PhD, MPH
AB 32 is correct to focus on energy alongside transportation, agriculture, building infrastructure, water, waste, and land use as useful measures for lowering emissions and combating climate change. However, if it is serious about reaching its goal it must include more focus on oil and gas production. The comments that follow will be directed towards climate change mitigation efforts and progress toward the 2020 goal, focusing in particular on the energy sector, GHG emissions, and the latest understanding of climate science.
