Two of the largest gas industry lobbying bodies in the US, the American Petroleum Institute (API) and American Natural Gas Alliance (ANGA), released a ‘study’ earlier this month claiming methane emissions from natural gas production to be 50 percent lower than the US Environmental Protection Agency’s 2011 estimates. However, according to a joint statement prepared by professors Robert Howarth and Anthony Ingraffea and released by the Physicians Scientists & Engineers for Healthy Energy (PSE) this week, the study is nothing more than industry-purchased propaganda that does not adhere to basic standards for scientific accuracy and consistency.
Here is a brief outline of the study’s ‘fatal flaws’ as outlined in the PSE joint statement:
The gas industry received a blow yesterday when the nonprofit group Physicians, Scientists & Engineers for Healthy Energy (PSE) released a joint statement by Professors Anthony Ingraffea and Robert Howarth of Cornell University. According to the release the EPA’s new emissions standards for methane and volatile organics from shale gas development “must be considered to little, too late” given the urgent need to reduce global levels of greenhouse gas (GHG) emissions.
“Despite the new regulations, shale gas methane emissions will remain significant, with the estimates of EPA (2011) and Howarth et al. (2011) indicating a likely leakage of 2.5 – 3.9 percent of the amount of methane produced over the lifetime of a shale-gas well, and possibly as high as 6 percent,” the statement reads.
