Exxon Now Wants to Write the Rules for Regulating Methane Emissions
And while the oil giant has been responsible for massive methane releases, Exxon has now proposed a new regulatory framework for cutting emissions of this powerful greenhouse gas that it hopes regulators and industry will adopt. As Exxon put it, the goal is to achieve "cost-effective and reasonable methane-emission regulations."
So, why is Exxon asking to be regulated?
The answer may be simply that Exxon is very good at public relations. As industry publication Natural Gas Intelligence reported, this announcement "comes as energy operators face increasing pressure from lenders and shareholders to engage in decarbonization by following environmental, social, and governance standards."
ExxonMobil is proposing new rules to cut methane emissions. We think it makes sense for industries to work together… https://t.co/NnLNZ2yO5O— ExxonMobil (@ExxonMobil)1583281279.0
Exxon's proposed regulations have three main objectives: finding and detecting leaks, minimizing the direct venting of methane as part of oil and gas operations, and record keeping and reporting.
Casey Norton, Exxon's Corporate Media Relations Manager, explained to DeSmog that Exxon's proposal was not expected to be adopted as-is by regulatory agencies. "This is a starting point for conversations with policy makers and other regulators," he said. "For example, New Mexico, Argentina, the EU, who are all considering new regulations for methane emissions."
Under President Trump, the federal government last year rolled back Obama-era rules for oil and gas companies to report methane emissions and for restricting these emissions during drilling on public lands.
This isn't Exxon's first foray into voluntary regulations of methane. The corporation's natural gas subsidiary XTO started a voluntary methane emissions program in 2017. In June 2018, XTO noted that the voluntary program, which was mostly about replacing leaking valves, had reduced methane emissions by 7,200 metric tons since 2016.
However, leaking valves are not the biggest source of methane emissions. In February 2018, four months before XTO was touting the success of its methane reduction program, the company experienced the second largest methane leak in U.S. history. A gas well it operated in Ohio suffered a blowout, releasing huge amounts of the heat-trapping gas.
Did XTO's voluntary program accurately report this? As The New York Times reported, "XTO Energy said it could not immediately determine how much gas had leaked."
But a group of scientists using satellite data eventually did pin down the amount released — 120 metric tons an hour for 20 days. That adds up to roughly 50,000 metric tons more released than the 7,200 metric tons in reductions XTO was claiming months later. That one leak was estimated to be more than the methane emissions of the total oil and gas industry of countries like Norway.
As DeSmog reported, XTO is also flaring the most natural gas of any company in the Permian oil field (natural gas is almost 90 percent methane). While flaring isn't as bad for the climate as directly venting the methane into the atmosphere, it is increasing the levels of carbon dioxide and toxic air pollutants and is another problem the industry is saying it will address even as the practice continues on a large scale.
And now the same company is recommending that the rest of the industry and regulators adopt their approach to regulating methane emissions.
"It is not target-based, it is not volume-based," Exxon's Norton said. "Again, it's starting a conversation, saying these are things that you can look at."
Robert Howarth, a biogeochemist at Cornell University whose work focuses on methane emmissions in the oil and gas industry, drew attention to areas of Exxon's framework he thought were lacking. For starters, he pointed out that the proposed framework does not mention emissions from "imperfect well casings and from abandoned wells," which Howarth says "can be significant." He also noted that the proposal does not describe "a methodology for characterizing any of these emissions; there are techniques for doing so, but there is not much demonstrated use of these techniques by industry."
Finally — and this is the real danger with any sort of industry self-regulation — Howarth said there must be some type of independent oversight to assess actual emissions instead of relying on the industry to self-report. XTO's well blowout in Ohio is an excellent example of why this third-party verification is critical. Without oversight, the "system is ripe for abuse," according to Howarth.
Sharon Wilson of environmental advocacy group Earthworks documents the oil and gas industry's current widespread practices of flaring and venting methane. Sharing her concerns about Exxon's methane emissions proposal, she told DeSmog,"Exxon's recent announcement is too little too late when it comes to the climate crisis they've help cause and are still making worse. Reducing methane emissions by any percentage is not enough when Exxon continues to expand sources of the same climate pollution."
Wilson called for the company to support federal and state rules to cut methane.
Trump Administration Reversed Existing Methane Regulations
Methane emissions have become a much bigger issue in the last decade since the U.S. boom in shale oil and gas produced by fracking. Despite overseeing a huge rise in oil and gas production, the Obama administration acknowledged the methane problem and proposed and adopted new methane emissions regulations, which the Trump administration has since repealed.
The Trump administration has staffed regulatory agencies with former industry executives and lobbyists who have been quite successful at rolling back environmental, health, and safety rules.
"EPA's proposal delivers on President Trump's executive order and removes unnecessary and duplicative regulatory burdens from the oil and gas industry," Wheeler said. "The Trump administration recognizes that methane is valuable, and the industry has an incentive to minimize leaks and maximize its use."
The problem with this free-market assumption is that Wheeler is wrong about the industry's financial incentive to limit methane emissions.

There is too much natural gas, aka methane, flooding world energy markets right now. Current prices to buy it are lower than the costs to produce it. The methane currently produced in Texas' Permian Basin spent a good portion of last year at negative prices. There is no financial incentive for producers in the Permian to voluntarily cut methane emissions in the current market environment.
That is why Permian producers are flaring (openly burning) it at record levels as well as directly releasing (venting) methane into the rapidly warming atmosphere. So much for letting the free market address the issue.
Even the Remaining Regulations Are Controlled by Industry
While the Trump administration has rolled back many regulations for the oil and gas industry, the regulatory system in the U.S. was already designed to protect industry profits — not the public or environment. When the federal government creates regulations, the process can be heavily influenced by industry lobbyists, and if they don't agree with the regulations, there are many ways they can get them revised to favor their companies.
While Exxon did publicly say in 2018 that it didn't support repealing the existing methane regulations, the company also wrote to the EPA voicing support for certain aspects of the American Petroleum Institute's (API) comments on the issue, and the API approved removing the regulations. In that letter Exxon used the same language it is now using with its propsed regulations, saying any rules need to be "cost-effective" and "reasonable." But if the regulations are cost-effective, will they actually be effective in reducing methane emissions in a meaningful way?

The Wall Street Journal recently highlighted the influence that the oil and gas industry and its major U.S. trade group the American Petroleum Institute can have over regulations. After the deadly 2010 Deepwater Horizon explosion and oil spill in the Gulf of Mexico, the federal government put into place new safeguards known as the "well control rule" in order to prevent another disaster during deepwater offshore drilling.
In 2019, the Trump administration revised the rule, weakening it, even though, as the Journal reported, federal regulatory staff did not agree "that an industry-crafted protocol for managing well pressure was sufficient in all situations, the records show." The staff was ignored. (And the move is undergoing a legal challenge.)
Industry crafted protocol. Just the thing Exxon is now proposing.
This type of industry control over the regulatory process was also brought to light after two Boeing 737 MAX planes crashed and killed 346 people. Boeing had fought to make sure that pilots weren't required to undergo expensive and lengthy training to navigate the new plane.
Reuters reported on internal communications at Boeing which revealed the airplane maker simply would not let simulator training be required by regulators:
"I want to stress the importance of holding firm that there will not be any type of simulator training required to transition from NG to MAX," Boeing's 737 chief technical pilot said in a March 2017 email.
"Boeing will not allow that to happen. We'll go face to face with any regulator who tries to make that a requirement."
Boeing got its way. And 346 people died.

For the past six years, I have reported on the failed regulatory process governing the moving of dangerous crude oil by rail (and even wrote a book about it). The only meaningful safety regulation that resulted from a multi-year process was requiring oil trains to have modern electronically controlled pneumatic brakes.
As I reported, shortly after this regulation was enacted, Matthew Rose, CEO of the largest oil-by-rail company BNSF, told an industry conference that "the only thing we don't like about [the new regulation] is the electronic braking" and "this rule will have to be changed in the future." As per the wishes of Matthew Rose, that rule was repealed despite the substantial evidence clearly showing this modern braking system greatly increases train safety.
A recent op-ed from an editor at the trade publication Railway Age referred to these oil trains as a "clear and present danger." Nevertheless, these trains hauling volatile oil through North American communities are still operating with braking systems engineered in the late 1800s.
Exxon Touts 'Sound Science' Despite Its History
Exxon's methane proposal states that any regulations should be based on "sound science." This statement is coming from a company whose scientists accurately predicted the impacts of burning fossil fuels on the climate decades ago and yet has spent the time since then misleading the public about that science.
The current regulatory system in America does not protect the public interest. Letting Exxon take the lead in the place of regulators doesn't seem like it's going to help.
Megan Milliken Biven is a former federal analyst for the U.S. Bureau of Ocean Energy Management, the federal agency that regulates the oil industry's offshore activity. Milliken Biven explained to DeSmog what she saw as the root cause of the regulatory process's failure.
"Regulatory capture isn't really the problem," Milliken Biven said. "The system was designed to work for industry so regulatory capture isn't even required."

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.
"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."
The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.
They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.
They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.
But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.
"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.
What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.
It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.
To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.
First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.
Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.
University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.
"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."
Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.
"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
