Article by LaPuma and MPH Alumnus Featured on Journal of Environmental Health’s Cover

Associate Professor Peter LaPuma is the senior author and MPH Alumnus Chris Sibrizzi is the first author of “An Assessment of Life Cycle Greenhouse Gas Emissions Associated With the Use of Water, Sand, and Chemicals in Shale Gas Production of the Pennsylvania Marcellus Shale.” Featured on the cover of the November issue of the Journal of Environmental Health, the article is based on Sibrizzi’s culminating experience. Their work is among the first to investigate the upstream life cycle greenhouse gas (LC-GHG) emissions associated with the use of hydraulic fracturing, or fracking. LaPuma and Sibrizzi used the Economic Input-Output Life Cycle Assessment model to assess LC-GHG emissions associated with production and transportation of chemicals and sand mining by focusing on 1,921 wells in Pennsylvania from 2012 to 2013. They calculated upstream inputs of 1,374 tons of CO2e per well, which they determined account for only 0.63% of the total LC-GHG emissions from hydraulic fracturing, including gas combustion, methane leakage, venting, and flaring from the other phases of the process.
