The U.S. Department of the Interior this week announced new fracking regulations that will serve as the only federal rules enforcing any kind of safety measures on the controversial drilling technique when they go into effect in a few months.
The rules only apply to oil and gas wells on public lands, however, and most fracking is done on private or state-...
NY Times' Joe Nocera Overlooks Key Flaws in EDF Fracking Climate Change Study
NY Times' Joe Nocera Overlooks Key Flaws in EDF Fracking Climate Change Study
Yesterday, New York Times' columnist Joe Nocera weighed in on the study by Environmental Defense Fund (EDF) and University of Texas-Austin (UT-Austin) on the climate change impacts of hydraulic fracturing (“fracking”). DeSmogBlog got a special mention in Nocera's op-ed titled, “A Fracking Rorschach Test.”
“The reason the Environmental Defense Fund wanted this study done is precisely so that unassailable data, rather than mere estimates, could become part of the debate over fracking,” wrote Nocera. “You can’t have sound regulation without good data.”
Missing from Nocera's praise: new findings by the Intergovernment Panel on Climate Change in their latest comprehensive review of the climate crisis.
IPCC revealed “over a 20-year time frame, methane has a global warming potential 86 [times the amount of] CO2, up from its previous estimate of 72 [times],” as explained by Climate Progress' Joe Romm.
In juxtaposition, Nocera dismissed DeSmog's criticisms of the study - one we referred to as “frackademia.”
Simplifying the crux of my 3,000-word DeSmog critique and the 800-word follow-up as “because the nine companies involved had both cooperated and helped pay for it,” Nocera then rhetorically asks “why a study that necessitated industry cooperation and money is inherently less valid than a study produced by scientists who are openly opposed to fracking was left unanswered.”
The answer: the scientists “openly opposed to fracking” whom he points to, Cornell University's Robert Howarth and Anthony Ingraffea - authors of the first major academic study documenting fracking's climate change impacts published in April 2011 - are not the only ones who have pointed to fracking's climate change perils.
Further, DeSmog's critiques of the EDF/UT-Austin study run far deeper than oil industry funding and conflicts of interest alone.
Recent Study: “Alarming High,” Findings Sans Industry Collaboration
Nocera - a self-described fracking supporter - overlooked a key study published in early August by 19 researchers primarily from National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado.

“The team determined that methane emissions from the oil and natural gas fields in Uintah County totaled about 55,000 kg (more than 120,000 lbs) an hour on the day of the flight,” a press release on the NOAA-University of Colorado study explained. “That emission rate is about 6 to 12 percent of the average hourly natural gas production in Uintah County during the month of February.”

EDF/UT-Austin found fugitive methane emissions rates at a scant .42-percent, far lower than the NOAA/University of Colorado study and 2-4% lower than the Cornell University study.
Like the EDF/UT-Austin study, the researchers did receive industry funding from the industry-funded Western Energy Alliance. Unlike the EDF/UT-Austin study, the samples taken did not require industry compliance because the researchers took them via 11 fly-overs of well production sites.
When the NOAA-Colorado study was released, EDF called the results “alarmingly high.”
Green Completions vs. Representative Sample: No “Super Emitters” Included
While the NOAA/University of Colorado study analyzed samples across an entire shale gas basin in Utah, the EDF/UT-Austin study honed in on well completion sites that the industry calls “green completions.” The U.S. Environmental Protection Agency will not mandate these completions until 2015, so they are not representative of the industry's performance at the moment.
“In the past, a well's initial production was typically vented or burned off to allow impurities to clear before the well was tied into a pipeline,” explained The Philidelphia Inquirer.
“Now, more operators are employing reduced-emission completions - a 'green completion; - a process in which impurities such as sand, drilling debris, and fluids from hydraulic fracturing are filtered out and the gas is sold, not wasted.”
Thus, while important measurements, the EDF/UT-Austin study - hailed as “unprecedented measurements” in a UT-Austin press release - neglected to measure any of the “super emitters,” as Climate Progress' Joe Romm pointed out.
“The 0.42 percent is the average of a bunch of good actors but not necessarily representative of the real world,” explained NOAA's Colm Sweeney, one of the Unitah Basin study co-authors, in an interview with EnergyWire. “The super-emitters are lost in a study released this week by scientists at the University of Texas, Austin, and the Environmental Defense Fund.”

In Howarth's original critiques of the study cited here on DeSmog, he echoed Sweeney.
“First, this study is based only on evaluation of sites and times chosen by industry,” wrote Howarth.
“The Environmental Defense Fund over the past year has repeatedly stated that only by working with industry could they and the Allen et al. team have access necessary to make their measurements. So this study must be viewed as a best-case scenario.”
Robert F. Kennedy Jr. - Chief Prosecuting Attorney for the Waterkeeper Alliance and a Senior Attorney for the Natural Resources Defense Council - sang a similar chorus about the study in a recent interview with National Public Radio's “Stateimpact Pennsylvania.”
”[EDF/Austin] studied wells that were experimenting with new technologies that are not industry-wide and not required for the industry to see if they could reduce methane rates, and indeed the rates were lower,” Kennedy stated.
Did Fracking Industry 'Partners' Guide EDF's Flawed Methodology?
Unexplored by Nocera - and still unanswered by journalists and researchers: whether the people and money behind the EDF/UT-Austin study and Steering Committee pushed the study in a direction that would produce industry-friendly results.
DeSmogBlog has filed a FOIA request with UT-Austin to find out what type of industry influence existed for the EDF/UT-Austin study, requesting all communications between the industry-stacked Steering Committee and UT-Austin faculty and staff.
Yet, the biggest takeaway from the EDF/UT-Austin study - despite efforts by industry front groups and lobbyists to assert it as definitive - is that fracking is proceeding at breakneck speed regardless of the still unknown and daunting scope of all the threats that unconventional oil and gas drilling poses to human health, ecosystems and the climate.
Bottom Line: Too Many Unanswered Questions to Allow Reckless Fracking
DeSmogBlog stands by the concluding recommendations in our 2011 report “Fracking the Future,” and would like to know which aspects of this position are objectionable to Mr. Nocera and others who are promoting the EDF/Austin study:
A national moratorium on hydraulic fracturing for unconventional gas until independent scientific studies are conducted to verify that fracking is not responsible for adverse outcomes on drinking water, public health and the global climate.
The federal government, not the states, should strictly oversee setting and enforcing standards for unconventional gas drilling. Federal oversight of the unconventional gas industry is critical, since the states have not demonstrated the capacity to hold drillers accountable for contamination of water supplies, growing air pollution problems and the potentially devastating climate change implications of fugitive methane and other emissions. Federal agencies should employ existing federal statutes that don’t currently apply to gas drilling, and review the need for any new standards necessary to protect public health and the environment.
Greater scrutiny is needed on common drilling practices such as cementing procedures, wastewater handling and storage of harmful drilling chemicals.
Congress and federal agency officials must immediately require mandatory industry reporting of lifecycle emissions of gas drilling operations to ensure relevant and reliable information is accessible to the public, especially independent experts.
- They must also require mandatory disclosure of fracking fluid chemicals, including the exact chemical recipes used in each operation.
As we concluded in our report, “uncertainties about the extent of methane emissions and leakage from drilling operations, storage tanks and pipelines carrying gas” remain a critical issue for scientists to assess. Without mandatory federal policy requiring industry disclosure of life-cycle methane leakage, we are all left in the dark about the true risks of the fracking boom.
