The Urgent Case for a Ban on Fracking i
I
n many ways, racking is he environmenal issue o our ime. I’s an issue ha
ouches on every aspec o our lives — he waer we drink, he air we breahe, he
healh o our communiies — and i is also impacing he global climae on whichwe all depend. I pis he larges corporae ineress — big oil and gas companies and
he poliical leaders who suppor hem — agains people and he environmen in a
long-erm sruggle or survival. I is an issue ha has capivaed he hears and minds
o hundreds o housands o people across he Unied Saes, Europe and across he
globe. And i is an area in which, despie he massive resources o he Frackopoly — he
cabal o oil and gas ineress promoing his pracice — we as a movemen are making
remendous srides as our collecive power coninues o grow.
Food & Waer Europe is proud o work shoulder o shoulder wih communiies across Europe and across he world in
his effor. Wih mouning evidence abou he harms o racking and he immediacy o he impending climae crisis,
his repor lays ou he urgen case or a ban on racking.In 2009, we became alarmed abou he hrea ha hydraulic racuring (racking) posed o waer resources across
he Unied Saes. Communiies around he Unied Saes were already raising he alarm abou he ill effecs ha
racking was having, rom increased ruck raffic o spills and even ap waer ha could be li on ire hanks o
mehane leaks rom racking wells ino waer sources.
Meanwhile, many naional environmenal groups were ouing naural gas as a “bridge uel” — a beter means o
producing energy rom ossil uels han coal, a source ha everyone knew we had o move away rom urgenly o
reduce he carbon emissions ha were heaing he plane a a dangerous rae. Communiies ha were already eeling
he effecs o he echnology, or ha were ighing he coming wave o racking, el berayed ha he place hey
lived could become one o he sacriicial zones — wih many environmenaliss’ blessing. Over he nex ew years,
scieniic evidence would moun ha no only is racking no climae riendly, bu i has he poenial o unleashmassive amouns o mehane ha will conribue o climae disaser.
So we began our work on racking wih Not So Fast, Natural Gas , our repor ha raised serious quesions abou
racking saey and he naural gas rush being promoed by indusry and governmen. Tha repor, released in 2010,
called or a series o regulaory reorms, bu he evidence coninued o moun. The nex year, afer looking a even
greaer evidence o he inheren problems wih racking, and realizing how inadequaely he saes were regulaing
he oil and gas indusry and enorcing hose regulaions, Food & Waer Europe was one o he irs European organ-
isaions o call or a complee ban on racking and we released he repor The Case for a Ban on Gas Fracking .
Since he release o ha repor in 2011, more han 150 addiional sudies have been conduced on a range o issues
— rom waer polluion o climae change, air polluion o earhquakes — reinorcing he case ha racking is simply
oo unsae o pursue. In he ace o such sudies, and ollowing he lead o grassroos organizaions ha have been a
he oreron o his movemen, a consensus is emerging among hose working agains racking ha a ban is he only
soluion. No only are decision-makers no regulaing he pracice o racking, i is so dangerous and he poenial so
grea ha i canno be regulaed, even i here were he poliical will.
As his repor lays ou, here is mouning evidence ha racking is inherenly unsae. Evidence builds ha racking
conaminaes waer, pollues air, hreaens public healh, causes earhquakes, harms local economies and decreases
propery values.
And mos criically or he survival o he plane, racking exacerbaes and acceleraes climae change. We are acing
a climae crisis ha is already having devasaing impacs and ha is projeced o escalae o caasrophic levels i we
do no ac now. Our eleced officials ou racked gas as a “bridge uel,” ye mouning evidence suggess ha raherhan serving as a bridge o a renewable energy uure, i’s a bridge o a climae crisis.

While he environmenal, public healh and ood movemens have looked a mouning evidence and rejeced racked
gas and oil, Presiden Obama and his adminisraion have aggressively promoed naural gas and domesic oil as a
criical par o he Unied Saes’ energy uure. Presiden Obama repeaedly ous domesic gas producion and has
said ha “we should srenghen our posiion as he op naural gas producer … [I] no only can provide sae, cheap
power, bu i can also help reduce our carbon emissions.” His Energy Secreary Ernes Moniz has close indusry ies
and has claimed ha he has “no seen any evidence o racking per se conaminaing groundwaer” and ha “he
issues in erms o he environmenal ooprin o hydraulic racuring are manageable.”
Despie wha he US governmen and indusry claim, here have now been over 150 sudies on racking and isimpacs ha raise concerns abou he risks and dangers o racking and highligh how litle we know abou is long-
erm effecs on healh and our limied reshwaer supplies. I’s ime or our eleced leaders o look a he acs and
hink abou heir legacy. How do hey wan o be remembered? Wha do hey wan he world o look like 20, 50 and
100 years rom now?
We irs made he case or a ban on racking in 2011, bu his new repor shows ha here is an urgen case or a ban.
The evidence is in, and i is clear and overwhelming. Fracking is inherenly unsae, canno be regulaed and should be
banned. Insead, we should ransiion aggressively o a renewable and efficien energy sysem.

Executive SummaryThe erm “racking” has come o mean more han jus
he speciic process o injecing large volumes o various
mixes o waer, sand and chemicals deep underground,
a exreme pressure, o creae racures in argeed rock
ormaions — all so ighly held oil and gas migh low.
We now use he erm racking o represen all ha his
speciic process o hydraulic racuring enails. Allowingmore racking means ha oil and gas companies will
coninue o:
Fragment forests and mar landscapes wih new
roads, well sies, wase pis and pipelines;
Compete with farmers for local water supplies
while consuming millions o liers o waer or each
racked well;
Produce massive volumes of toxic and even
radioactive waste, he disposal o which is causing
earhquakes and puting a risk drinking waerresources;
Cause thousands of accidents, leaks and spills
each year ha hreaen public healh and saey
and pu a risk rivers, sreams, shallow aquiers and
arms;
Pump hazardous pollutants into the air, a he
expense o local communiies, amilies and arms;
Turn homes into explosive hazards by conami-
naing waer wells wih mehane and oher lam-
mable gases; Put vital aquifers at risk for generations by
creaing new pahways or he poenial low o
conaminans over he coming years and decades;
Destabilize the climate on which we all depend
wih emissions o carbon dioxide and mehane and
by locking in uure climae polluion wih new oil
and gas inrasrucure projecs; and
Disrupt local communities, wih broad physical
and menal healh consequences, increased demand
on emergency and oher social services, damage o
public roads, declines in propery value, increased
crime, and losses el in esablished secors o local
economies.
In 2011, Food & Waer Europe called or a ban on
racking because o he signiican risks and harms ha
accompany he pracice. Now, over hree years laer,
numerous peer-reviewed sudies published in scieniic,
legal and policy journals have expanded wha is known
— and clariied wha remains unknown — abou he
environmenal, public healh and socioeconomic impacs
ha sem rom racking. In his repor, Food & Waer
Europe reviews he science and renews is call or a ban.
We ind ha he open quesions amoun o unaccepable
risk, and ha he harms are cerain. Sringen regulaions,
even i pu in place and even i adequaely enorced,
would no make racking sae. Municipal bans, mora-
oria and zoning laws are being passed o ry o proec
communiies across he counry, bu ederal and sae
level acion is necessary o reverse he spread o racking.
The only pah o a susainable economic uure is o
rebuild he our energy sysem and local economies around
sae energy soluions: efficiency, conservaion and renew-
able resources. Fracking akes us in he wrong direcion.
IntroductionHydraulic racuring allows oil and gas companies oarge underground layers o rock ha hold oil and
gas, bu ha do no readily allow he oil and gas o
low up a well. Drilling hrough hese rock ormaions,
hen injecing a blend o waer, sand and chemicals a
exreme pressure, creaes racures propped open by he
sand, exposing oherwise ighly held oil and gas and
allowing i o low.

In response o declines in convenional producion, and
o he lack o access o many inernaional sources o
oil and gas,1 companies are now racking in he Unied
Saes on an unprecedened scale. (See Box 1.) Acids are
also being injeced, paricularly in Caliornia and perhaps
increasingly in Florida, o ea away new pahways or oil

The oil and gas indusry enjoys avored saus under

our economy, as we ace he consequences o global
warming and he legacy o he indusry’s polluion.
The curren saus quo a he ederal level, and in many
saes, is o encourage as much drilling and racking or
oil and gas as possible. Increased poliical and legislaive
gridlock in Washingon, D.C. has helped o mainain
his saus quo.14 Those wih large sakes in oil and
gas producion — a angle o oil and gas companies,

The scale of fracking To hydraulically fracture a modern onshore oil or
gas well, batches of millions of liters of water, tons of
sand and thousands of liters of chemicals get injected
repeatedly, typically in tens of stages along a two and
a half kilometer long, several-inches-wide tunnel,
or borehole, that runs laterally through a targeted
rock formation thousands of feet below ground. Oil
and gas companies are now doing this more than10,000 times each year in the United States to extract
so-called shale gas, tight gas and tight oil.3 Acids are
and this is not always done at pressures high enough
largely unknown, but the practice is clearly on the rise
and a focus of the oil and gas industry.4
In 2012, the U.S. Energy Information Administration
estimated that bringing the projected amounts of
technically “recoverable” — as if recovering some-thing lost — shale gas and tight oil into production
would require drilling and fracking over 630,000 new
onshore wells.5 If this happens, many thousands of
the wells envisioned are likely to have cementing and
casing issues from the outset, and all of them will age
and degrade over subsequent years and decades,
putting at risk underground sources of drinking
water.6 Given that initial fractures release just a small
fraction of the oil or gas held in targeted source rocks,
industry will also seek to re-fracture many thousands
of these wells to try to reverse the typically rapid
declines in production as they age.7
A 2013 analysis from the Wall Street Journal found that
over 15 million Americans are living within one and a
half kilometers of a well drilled after the year 2000,
when large-scale hydraulic fracturing operations
began.8 Many more live alongside other polluting
infrastructure that supports oil and gas production,
including processing plants, compressor stations
passed actions in opposition to drilling, fracking and
supporting infrastructure.9
Oil and gas companies have piled up over $100 billionin debt, in large part to support drilling and fracking
and related infrastructure.10 Data from the major
publicly listed oil and gas companies show that from
2008 to 2012, collective capital spending increased by
about 32 percent, while, at the same time, oil produc-
tion fell by about 9 percent.11 Evidently the industry
is banking that increased drilling and fracking into
the future, coupled with increased oil and natural gas
that oil and gas prices rise.12 Industry’s bubble will
burst, not least because society’s systematic depen-
dence on fossil fuels is posing an existential threat by
destabilizing our climate.13

oil and gas. These impacs are due in large par o he
oxic naure and pervasive spread o he chemical pollu-
ans ha he indusry brings o he surace. (See Box
2.) Recen research urher reveals how hese and oher
impacs collecively damage public healh and disrup
communiies.
Pu simply, widespread drilling and racking or oil and
gas is inherenly unsae and erribly shorsighed. Thisrepor explains why i is ime or a ban. The oil and
gas indusry’s corruping inluence on American policy
and governmen hreaens o coninue he harm, and
o coninue o supplan proven and sae soluions or
meeing energy needs.
Water and Land ImpactsThe oil and gas indusry’s capure o U.S. energy policy
has colored several high-proile invesigaions o aquier
conaminaion in he afermah o drilling and racking,
namely in Pavillion, Wyoming, in Dimock, Pennsylvania,
and in Parker Couny, Texas.
The pollutants that the oil and gas industry brings to the surface
“Natural gas,” “natural gas liquids,” “crude oil,” “drilling muds” and “produced water” are innocuous-sounding terms
that conceal the nature of all that the oil and gas industry brings to the surface.
of hydrocarbons is called crude oil when the bulk of the hydrogen and carbon atoms that make up the mix are
bound together in large molecules, and the mix is liquid when it reaches the surface.23 The term natural gas liquids

But drilling and fracking brings much more to the surface than just these hydrocarbons.

Many of the hydrocarbons brought to the surface are hazardous pollutants, including volatile organic compounds

Finally, oil and gas companies bring to the surface various amounts of the chemicals used in fracking, and byproducts
from reactions involving these chemicals.34 Given trade-secret protections in federal and state laws, and otherwise
often even to the company doing the injecting.35

inducing new fractures.37
With the exception of the fracking chemicals and the byproducts of any fracking
chemical reactions, all of the above chemical pollutants had long been safely
sequestered and immobilized, deep underground. Now, drilling and fracking
brings these pollutants to the surface at baseline levels that risk human health
and environmental damage through water, soil, air and climate pollution. Then
there are the greater-than-baseline levels of contamination: the accidents, leaks,
dangerous to clean up, to the extent that they can be cleaned up.
The liquids, sludge and solids that remain from what the industry does not leak into
the air, spill on the ground, burn or otherwise use, are adding up to create waste
disposal problems. This pollution is part and parcel of the current “all-of-the-above”
approach to U.S. energy policy. All of the above pollutants need to stay underground.

The Urgent Case for a Ban on Fracking 5
In December 2011, he U.S. Environmenal Proecion
Agency (EPA) published a draf scieniic repor on
groundwaer conaminaion in Pavillion, Wyoming,
saing ha wase pis likely conaminaed shallow
groundwaer38 and ha daa on chemicals deeced in
a deeper monioring well “indicaes likely impac o
ground waer ha can be explained by hydraulic rac-
uring.”39 The draf repor called or more monioring
o wells o make he indings o he repor more deini-
ive.40 In he ace o exreme pressure rom he indusry
and rom indusry advocaes in Congress, however, he
EPA decided in 2013 o abandon inalizing he repor.41
Insead, he EPA deerred i o he Sae o Wyoming,
which will rely on he company implicaed in he case o
und a new invesigaion.42 While he EPA claims ha i
sill “sands behind is work and daa,”43 he rerea was
widely repored as a vicory or he indusry.44
In 2012, he EPA similarly rereaed rom is invesiga-
ion o waer conaminaion cases in Dimock, Penn-sylvania,45 which he sae’s environmenal agency had
deermined were due o “drilling aciviies.”46 The EPA
had ound conaminans in several o he waer wells
in quesion, bu simply saed ha “he residens have
now or will have heir own reamen sysems ha can
reduce concenraions o hose hazardous subsances o
accepable levels a he ap.”47 The EPA ailed o evaluae
he reasons or he conaminaion, again leaving he
public wih he alse impression ha affeced residens’
claims o conaminaion had no meri.48
In December 2014, he EPA will issue a draf o a muli-
year sudy on he poenial impacs o racking on
drinking waer resources. In his sudy, he agency is
relying heavily on volunary cooperaion rom he oil
and gas indusry or daa and experise. This reliance on
indusry parly explains he EPA’s rerea on he hird
high-proile case o conaminaion linked o drilling and
racking, in Parker Couny, Texas.49 According o he EPA’s
Inspecor General, a primary reason ha he agency
wihdrew is emergency order agains he company doinghe drilling and racking was ha he company agreed
o paricipae in he EPA’s ongoing sudy.50 This episode,
in paricular, highlighs how he indusry’s conrol over
daa and experise shapes he science and invesigaions
carried ou on behal o he public.
The residens o Parker Couny, Dimock and Pavil-
lion wen o he EPA because hey did no eel ha
heir respecive saes were being responsive o heir
concerns. Texas, Pennsylvania and Wyoming each have
long hisories o promoing oil and gas developmen, in
he name o prevening “wase” o oil and gas reserves,51
and are pary o inersae resoluions o encourage
shale gas exracion and “expansion o naural gas
inrasrucure.”52 The EPA’s unwillingness o complee
invesigaions o hese hree landmark cases o drinking
waer conaminaion means ha he affeced residens
have nowhere else o urn.
Generally, he risks and impacs o waer resources
include he indusry’s compeiion or waer, land and
surace waer polluion, and aquier conaminaion.53
Water consumptionAffordable access o clean waer is a public healh issue,
and a human righ. Public waer sysems already ace
major challenges ha will be exacerbaed by global
warming, in he orm o locally severe droughs, exreme
sorms and oherwise alered rainall, snowall andsnowmel paterns.54 Over a cenury o climae polluion
semming rom he oil and gas indusry conribues
signiicanly o his warming.55
Now, wih widespread drilling and racking, he oil and
gas indusry is no jus adding more climae polluion, i is
adding signiican demand or resh waer in already waer-
sressed regions o he counry. Even worse, i is leaving a
legacy o waer polluion and landscape disurbance.
Waer use per well varies by region, bu companiesypically require abou 20 million liers o waer o drill
and rack a single shale gas or igh oil well.56 Some hori-
zonal wells in he Eagle Ford shale play in Texas have
been racked wih more han 49 million liers each.57
Esimaes vary as o how much injeced luid reurns,
rom beween 5 and 50 percen.58 In he Marcellus
region, beween he irs sage o racking and he ime
he new well is pu ino producion, he liquid ha lows
up he well amouns o only abou 5 percen o he
volume injeced.59 Thus, almos all o he waer used in
racking luids is no available or reuse, and is under-ground indeiniely.

Oil and gas advocaes claim ha heir waer use is low
relaive o overall waer use, bu saisics ha average
over large regions are decepive. Fracking’s use o waer
can be inensive, happening all in a local hospo or
drilling and racking and all a once or each new well.
Cold-waer sreams in norhern Pennsylvania, where
Marcellus shale developmen is concenraed, have
relaively small low raes,60 ye wihdrawals or rackinghave been primarily rom surace waers, wih wih-
drawals rom public waer sysems indusry’s second
choice.61 Regulaors anicipae increased use o ground-
waer in he region over he coming years i he pace o
drilling and racking coninues.62
A 2014 repor by Ceres looked a indusry-repored
daa on 39,294 oil and gas wells racked beween
January 2011 and May 2013, and deermined ha 39
percen were in regions wih “high waer sress” and
8 percen were in regions wih “exremely high waersress.”63 Waer sress is a measure o waer compei-
ion in a region, and regions wih “high waer sress”
are hose where oal waer wihdrawals (no jus or
racking) make up 40 o 80 percen o he oal waer
available or wihdrawal, while “exremely high waer
sress” means ha more han 80 percen o available
waer is being wihdrawn.64 The repor also deermined
ha over 36 percen o he oil and gas wells included in
he sudy were in regions ha will “experience ground-
waer depleion.”65
To rack he Barnet Shale in Texas, oil and gas compa-
nies used groundwaer and surace waer in equal
measure unil 2006, and increased he use o surace
waer o abou 70 o 80 percen o oal waer use rom
2007 o 2010, bu have since increased groundwaer
wihdrawals.66 The groundwaer wihdrawals are
primarily rom he Triniy aquier, which is “among he
mos depleed aquiers in he sae.”67
A paricular concern is he exen o which oil and gas
companies are compeing wih armers or access o
limied reshwaer resources. In 2012, a a Colorado
aucion o waer righs, oil and gas companies were
he op bidders, driving up waer prices or he sae’sarmers, many o which were enduring severe drough
condiions.68 In New Mexico, some armers affeced by
severe drough condiions are, in lieu o arming, selling
heir righs o irrigaion waer o oil and gas companies.69
This compeiion wih, or ourigh displacemen o,
agriculural waer use will only increase i unconven-
ional oil and gas developmen coninues o expand in
counies ha already ace waer sress, and ha are
likely o experience even larger waer supply problems
as a consequence o climae change.
Impacts on surface waters,
forests and soilsThe consrucion o new well sies and supporing
inrasrucure are jus he irs sage in he indusry’s
harm o surace waers, oress and soils. Each Marcellus
Shale gas well pad sis on abou hree acres o cleared
land, and or each sie anoher six acres is cleared o
build supporing access roads, pipelines and oher
ossil uel inrasrucure.
70
The indusry’s consrucionprojecs increase he amoun o sedimen ha lows
ino rivers and sreams, causing ecological harm ha is
compounded by excessive waer wihdrawals.71
Foress and agriculural lands provide waershed-scale
ilraion as rainwaer and snowmel low ino rivers
and recharge aquiers.72 Widespread shale developmen
in he Marcellus region is expeced o cover hundreds
o housands o acres wih suraces ha are impervious
o rains, signiicanly disruping his ilraion.73 New
indusry sies, pipelines and roads also expose more
ores o more clearing, changing he balance o wild-
lie, harming ores healh and hus urher affecing
waersheds and groundwaer recharge.74 Air polluans,

well-sudied reasons why, and he scale o he problem
derives rom he scale o widespread drilling.
Abou 2.6 million onshore oil and gas wells have been

20 years ago, he EPA esimaed ha abou 200,000 ohe over 1 million abandoned oil and gas wells in he
counry were inadequaely plugged, meaning ha hey

luids, o low up o he surace or o underground
sources o drinking waer.119
Addiionally, over 30,000 wells have been drilled or he
purpose o disposing o oil and gas indusry wases, via
injecion.120 A gray area lies in how he indusry akes

hese injecion wells or “enhanced oil recovery.”121
Consruced o concree and seel, all o he above

he beginning o heir consrucion, a signiican rac-
ion o oil and gas wells — several percen — have
well inegriy problems, meaning ha injeced luids,

Due o a variey o reasons, including cemen shrinkage
and/or poor bonding, space can orm beween he ouer

which an oil and gas well passes, creaing a pahway or

A PhD hesis in peroleum engineering, compleed in
May 2014, explains ha highly pressurized luids duringhydraulic racuring can direcly cause such separaion,

Gradual setling over ime due o he exracion o oil

As he many differen mechanisms o well ailure sugges,

Oil and gas indusry earhquakes have aken many
by surprise, bu scieniss have long known ha injec-

anicipaed he recen incidens in Norh Dakoa in
which anks holding oil and gas indusry wases have
been sruck by lighning, resuling in explosions ha
spilled conaminans ono surrounding lands and burned

because, in an effor o avoid corrosion, he meal anks
are lined wih iberglass, which has much lower conduc-
iviy han meal and hus overheas.189
Trains carrying igh oil rom drilling and racking in heBakken region o Norh Dakoa are also exploding.190
The surge in igh oil producion in Norh Dakoa and
Texas has led o a rapid expansion in he ranspor o
oil by rain o reineries, in par because producion
has oupaced pipeline consrucion.191 Energy Secreary
Ernes Moniz has noed ha he oil indusry has acu-
ally begun o preer ransporing oil by rain, or he
lexibiliy i offers.192 However, several oil rain explo-
sions — mos caasrophically in Lac-Méganic, Qebec,
which desroyed several blocks o he own and killed 47
people — have brough he so-called bomb rains o heoreron o public atenion.193
The our high-proile explosions hus ar — in Qebec,
Virginia, Alabama and Norh Dakoa — relec ha

relec ha large quaniies — ofen more han 10 million
liers per rain — are now being sen very long disances

The oil rain explosions have brough he issue o
racking o regions ha are no acively argeed or

Alabama and he Paciic Norhwes.196 For example,
abou 250 oil rain cars pass hough downown Seatle

ironically including he conversion o aciliies inended
or renewable liquid uels — would add as many as 12
one and a hal-kilomeer-long oil rains each day o he
Norhwes railway sysem.198
Taken ogeher, he earhquakes, lighning srikes and
exploding rains are a reminder ha widespread drilling
and racking now means many differen hings o hecommuniies ha are affeced in differen ways. Bu

differen sreams o polluans lowing ino he air: he

mining has broadened he reach o racking’s impacs
beyond regions argeed or shale gas and igh oil exrac-
ion, wih large amouns o silica mined rom or processed
in Wisconsin, Minnesoa, Illinois and Iowa.200
A recen review o he public healh impacs o drilling
and racking summarizes ha “[r]espirable silica can
cause silicosis and lung cancer and has been associ-
aed wih uberculosis, chronic obsrucive pulmonary
disease, kidney disease, and auoimmune disease.”201
The Naional Insiue o Occupaional Saey and

Residens living nearby operaions may also ace serious

an individual living across he sree rom a Wisconsin

Byproducts from combustionExhaus rom he diesel generaors and large rucks ha

Along wih carbon dioxide rom combusion, hese

The pollutants that oil and gascompanies bring to the surfaceThe hird sream o oil and gas indusry polluion orms
ou o he plumes o well- or sie-speciic mixes o
hydrocarbons and oher air and/or climae polluans,
as discussed in Box 2 (page 4). These are he polluans
ha come rom below ground, and ha are mobilized
ino he air in he afermah o drilling and racking.
Now, based on a handul o sudies in 2013 and 2014,
i has become clear ha he oil and gas indusry emis
more air and climae polluans han officials esimae.
The air and climae polluans ha oil and gas compa-
nies bring o he surace include: mehane and oher
VOCs, such as he BTEX hydrocarbons and oher
“aromaic” hydrocarbons, including PAHs; hydrogen
sulide; radon derived rom radium presen in argeed
rock ormaions; and any chemicals rom racking
suspended in he air as vapor or aerosol, such as gluar-
aldehyde, ehylene glycol and mehanol.210

rom inefficien lares and leaky valves, langes, seals,

Again, mehane is a poen greenhouse gas and a
primary driver o global warming.212 The BTEX air oxics
irriae skin and can cause respiraory and nervous
sysem problems wih shor-erm exposure, and can
cause greaer harm wih long-erm exposure, including
cancer.213 In he presence o sunligh, BTEX and oher
VOCs also combine wih combusion byproducs o

resuling in harmul levels o exposure or humans
who consume conaminaed ish.215 Hydrogen sulide
is highly poisonous, and oil and gas indusry workers
a well sies may be advised o wear personal moniors
equipped wih alarms.216
The chemicals in racking luid, as well as largely
unknown byproducs o chemical reacions during
racking, are mobilized along wih hydrocarbon gases
and oher polluans, and emited ino he air o varying
degrees.217 This pus he issue o racking chemical
disclosure ino proper perspecive as a signiican bu
noneheless singular componen o he indusry’s pollu-
ion. Full chemical disclosure would no pu an end o
he indusry’s waer and air polluion.
The issue o racking chemical secrecy noneheless reso-
naes wih he public, in par because i is an example o
he deerence ha policymakers regularly gran o oil and
gas companies, and because i illusraes how such deer-
ence holds back scieniic invesigaions o he indusry’simpacs on public healh and he environmen. Indeed,
some in he oil and gas indusry have worked wih he
American Legislaive Exchange Commission (ALEC), and
ALEC has in urn helped o see ha sae legislaures
only consider disclosure requiremens ha are accepable
o he indusry.218 Even when disclosure is required in
he even o emergencies, as is he case in some saes, a
company can be slow o comply.219
While regulaions vary by sae, rade-secre proecions
graned in he Toxic Subsances Conrol Ac mean haracking companies ypically do no have o disclose
all he chemicals hey pump underground.220 In ac, in
many cases, oil and gas companies old off-he-shel
producs ino he racking luids ha hey make on-sie,
wihou acually knowing he chemicals conained in
hese producs.221
I is known ha oil and gas companies have injeced a
wide variey o oxic chemicals o racure wells, and
have injeced many more chemicals or which oxici-
ies are no well sudied.222 For example, among hechemicals ideniied, over 100 are known or suspeced
endocrine disrupors.223 Numerous known or suspeced
carcinogens also have been used since 2005 as addiives
in hydraulic racuring luids.224 Many o he known
chemicals used are volaile, meaning ha hey escape
readily ino he air.225 Very litle is known abou healh
risks posed by mixures o all he chemicals brough o
he surace, and he exen o chemical reacions ha
orm dangerous byproducs.226
Beyond inadequae requiremens or disclosure o
racking chemicals, here are many oher undamenal
challenges o quaniying he oil and gas indusry’s
releases or each o he above polluans.
The challenges begin wih he number and diversiy o
sources, and how he consellaion o sources changes
over ime as he oil and gas indusry operaes, arges
new areas and adops new pracices.227 Geological
differences rom well o well, and differen sages wihinhe oil and gas sysem — rom producion o disribuion
— give rise o differences in he chemical composiions
o wha ges released ino he air.228 The low rae and
chemical composiion o he plumes rom a single source
can also change over ime, under normal operaions,229
and can increase quickly, and unexpecedly, as a conse-
quence o equipmen ailures.
These acors make he size and chemical composiions
o he plumes in he hird sream o emissions variable,
or well- and sie-speciic. Imporanly, undersandingo he indusry’s emissions is blocked by lack o access
o sies and o daa held by oil and gas companies,
presuming ha hey have daa. As noed already, hese
companies are empowered by rade-secre proecions
and by key exempions graned o he oil and gas
indusry under he landmark environmenal laws. A
PhD hesis compleed in 2014 reveals anoher obsacle
o ull inormaion: sources no couned a all, such as
abandoned oil and gas wells leaking mehane and oher
hydrocarbon gases.230

Agains hese challenges, he EPA esimaes emissions
using a botom-up approach, beginning wih an inven-
ory o all o he differen indusry aciviies underaken
in a given year.231 The EPA hen uses largely daed esi-
maes o average emissions o each aciviy o arrive a
an esimae o oal emissions rom he oil and naural
gas sysems.232 This approach relies heavily on volunary
sel-reporing rom he indusry.233
In 2013, he EPA Inspecor General ound many oil and
gas indusry emission acors o be o “low or unknown
qualiy” due o insufficien daa, leading o a resul ha
“likely underesimaes acual crieria polluan emissions
rom oil and gas producion sources.”234 For example,
here are no emission acors or air oxics and VOCs
emanaing rom wase pis, rom produced waer anks,
rom seps in he well compleion process including he
speciic process o racking, and rom pneumaic devices,
or pressure valves.235
Daa on he acual levels o various hydrocarbons in
he amosphere, aken rom aircraf lighs and/or rom
surace monioring locaions, make possible an alerna-
ive, op-down approach o esimaing indusry emis-
sions. Using amospheric chemisry, scieniss ake hese
daa and hen combine hem wih daa on wind paterns
o esimae, working backward, wha he dynamic
sreams o mehane and oher hydrocarbons were ha
lowed ogeher over an oil and gas play and gave rise o
he hydrocarbon levels ha were measured.236
Scieniss using his aircraf measuremen approach in
Uah, Colorado and Pennsylvania sugges ha much
more mehane and oher air polluans are lowing rom
oil and gas sies han botom-up esimaes based on
daed emission acors and indusry sel-reporing.237
Flying over an oil and gas ield in Uah one day in
February 2012, Karion e al. measured very large levels
o mehane — he equivalen o beween 6.2 percen
and 11.7 percen o naural gas producion ha monh,
assuming ha he day was represenaive o dailyemissions ha monh.238 In April 2014, Caulon e al.
published a sudy o mehane emissions during he
drilling sage a well sies in Pennsylvania and ound
several super-emiters, each releasing 100 o 1,000 imes
he EPA’s esimae o emissions during he drilling phase,
as uilized in is botom-up, invenory esimaes.239 In
May 2014, Péron e al. looked a mehane emissions in
he Denver-Julesberg basin in Colorado over a wo-day
srech in 2012 using monioring equipmen on owers
and on aircraf lown above he play, and concluded
rom he measuremens ha mehane emissions
were “close o 3 imes higher han an hourly emission
esimae based on EPA’s Greenhouse Gas Reporing
Program daa or 2012.”240
Because o variabiliy rom sie o sie, mehane emis-
sions can be used only as a crude indicaor o emissions
o oher polluans brough o he surace by he oil
and gas indusry. Noneheless, hese resuls are consis-
en wih he EPA Inspecor General’s conclusion ha
curren invenory esimaes undersae he oil and gas
indusry emissions o air oxics and oher VOCs, no jus
mehane.
Imporanly, Péron e al. esimaed ha benzene
emissions were abou seven imes larger han he
Colorado invenory esimaes would sugges.241 The
ac ha benzene emissions were evidenly no jus
approximaely hree imes larger, consisen wih he
inding on mehane emissions, bu closer o seven imes
larger, shows how simple, generic (i.e., linear) ormulas
or inerring non-mehane VOC levels rom mehane
levels can mislead. Simple inerence o non-mehane
VOCs rom mehane can hide poenially crucial — and
harmul — differences in he composiions o he raw
hydrocarbon gases rom well sies, as well as hide differ-
ences in he composiions o he differen sreams onaural gases managed a differen sages in he naural
gas sysem. In oher words, ar more harmul gases han
have been esimaed may be lowing rom some wells in
some regions, no jus rom he Denver-Julesberg basin.
This highlighs ha widespread drilling and racking is
a large, unconrolled experimen, and ha he conse-
quences or human healh remain largely unknown.242
Top-down sudies based on aircraf measuremens only
provide a look a emissions over a shor ime span, and
rom sources wihin relaively small areas o indusryaciviy. A paper published in December 2013 by Miller

auhors suggesed ha acual emissions were more han
30 percen higher han he EPA’s esimae a he ime.243
In a review published in February 2014, Brand e al.
surveyed he scieniic lieraure on oil and gas indusry
mehane emissions and likewise concluded ha he
botom-up, invenory approach used by he EPA signii-
canly underesimaes naional mehane emissions.244
Natural gas dependence causes
more global warming than thought
Because undersanding o naional mehane emissions
is lacking, he climae impacs o widespread drilling and
racking are a mater o curren debae.245 Bu he over-
whelming ocus o his debae on he climae impacs o
using naural gas insead o coal o generae elecriciy
loses sigh o he oil and gas indusry’s role as a major
source o climae polluion.
Abou wo hirds o U.S. climae polluion sems rom
he oil and gas indusry, wih a litle under 30 percen
semming rom naural gas producion, processing,
ranspor and use.246 However, he esimaes o mehane
leakage used o arrive a hese igures are based on he
official underesimaes discussed above.247 The above
igures on climae polluion semming rom he oil and
gas indusry also hinge on comparisons o he relaive
conribuions o he differen greenhouse gases o global
warming.248 Now, according o he consensus science
ha is presened in he mos recen Inergovernmenal
Panel on Climae Change (IPCC) assessmen, i is clear
ha officials have also been grealy underesimaing hepoency o mehane as an agen o climae change.249
The IPCC now saes ha, pound or pound, a pulse
o mehane rom he oil and gas indusry raps 36
imes more hea han a pulse o carbon dioxide, over
a 100-year ime rame, and raps 87 imes more hea
over a 20-year ime rame.250 Remarkably, since he irs
IPCC assessmen repor, each subsequen repor — in
1996, 2001, 2007 and mos recenly 2013 — has increased
he esimae o mehane’s “global warming poenial,”
relaive o carbon dioxide.251 The mos recen increase
was he larges,252 raising he quesion o wheher more
increases are in sore as climae science progresses.
Nowihsanding he signiican climae polluion rom
he naural gas sysem, advocaes o naural gas have
oued he uel as a ool or addressing he challenge
o global warming.253 Debae over he climae impacs
o swiching o naural gas rom oher ossil uels has
become conroversial, in par because i is based on a
alse choice: burn naural gas or burn oher ossil uels.
Framing he climae impac o racking in his way losessigh o hree crucial poins.
Firs, mos recenly, racking is being done primarily
o exrac oil. Since he end o Augus 2012, abou 75
percen or more o drilling rigs have argeed primarily
oil, no naural gas, and abou wo hirds o all he
drilling rigs operaing in he Unied Saes are he sor
capable o drilling horizonally hrough shale and igh
rock ormaions.254 Fracking makes i possible o bring
o he surace and burn much more oil han previously
imagined, and here has never been any preenseha such oil consumpion is anyhing bu bad or he
climae.255 Second, increased naural gas use in he
elecriciy secor does no jus displace oher ossil uels,
i displaces cleaner soluions, such as solar, wind and
efficiency.256 Third, much o he coal displaced, insead o
saying underground, is jus being expored and burned
in oher counries, offseting, a an inernaional level,
he U.S. reducions in carbon dioxide emissions ha
come rom swiching o naural gas.257 The claim ha
hese oher counries would jus burn coal rom else-
where anyway258 relecs he excepionally low sandards

These hree caveas se aside, Food & Waer Europe

under which using naural gas insead o oher ossil

he leakage o mehane rom he naural gas sysem,
and jus how much hey are offse remains an open and
conroversial quesion.260
There are a variey o ways o compare mehane emis-
sions o carbon dioxide emissions, in order o begin o
quaniy he climae impacs o burning naural gas
insead o coal, or heaing oils, or gasoline or diesel.261
Mehane does no persis in he amosphere or as longas carbon dioxide, so merics used o compare emissions
o he wo greenhouse gases depend on he ime rame
considered. 262 Focusing on he nex ew decades, a ime
rame in which mehane raps much more hea han
carbon dioxide does, pound or pound,263 is necessary or
hree undamenal and pressing reasons.264
The irs reason is ha we ace he risk ha climae
ipping poins will be surpassed in he near erm,
meaning ha naural posiive eedbacks could kick in
and lead o irreversible changes.265
For example, reducedArcic ice coverage means more absorbed sunligh
and warming.266 Furher, any warming ha haws ice
crysals ha had rapped mehane will give rise o
more mehane emissions, and hus more warming.267
Indeed, hawing o permaros in he Yamal Peninsula
in Russia, and he subsequen release o massive
amouns o mehane, likely explains he ormaion o
seemingly botomless craers in July 2014.268 Second,
even discouning he risk o climae ipping poins, he
changes o he climae ha are already expeced o
accompany 2 degrees Celsius o pos-indusrial warmingpromise o be dangerous and cosly.269 Third, curren
climae science warns ha o have a “good” chance —
ha is, signiicanly beter han a 50-50 chance — o
keeping warming rom going beyond 2 degrees Celsius
requires a very rapid ransiion off o all ossil uels,
leaving mos underground.270
Reurning o he quesion o mehane leakage, a 2012
sudy ound ha naural gas leakage ha amouns o
more han abou 3.8 percen o naural gas consump-
ion means ha swiching rom burning coal o burning
naural gas o generae elecriciy would be worse or
he climae or abou 20 years, a wash a 20 years, and
marginally less damaging hereafer.271 The auhors
urher deermined ha leakage a abou 7.6 percen
would make such a swich worse over a 100-year
horizon.272 These breakeven leakage raes were calcu-
laed, however, using he now oudaed esimaes o
mehane’s poency as a driver o climae change.273
Now, looking over he 20-year horizon, he breakeven
leakage rae is closer o 2.8 percen or elecriciy
generaion, when accouning ully or he new IPCC
esimaes o mehane’s poency.274 Similarly, on he
20-year ime rame, he breakeven leakage raes are
also lower, now a abou 0.9 percen when naural gas
displaces diesel in heavy rucks and 1.7 percen whennaural gas displaces gasoline in cars, alhough boh o
hese breakeven leakage raes do no incorporae several
acors ha would make hem even lower.275 As saed
already, naural gas leakage in 2010 amouned o more
han 3 percen o consumpion in 2010.276 I remains
o be seen how much more naural gas han 3 percen
leaked hen, and wheher much more han 3 percen
coninues o leak.277
Thereore, a bes, i will ake decades beore swiching
