Fossil Fuel Companies Use Enclosures to Hide Planet-Heating Methane Flares

Fossil fuel companies are using a technology known as enclosed flaring to conceal dangerous methane emitted during the production of fossil gas, a report published Thursday revealed.

The Guardian's Tom Brown and Christina Last reported that fossil fuel producers in countries including the United States, United Kingdom, Germany, and Norway "appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions, and pollutants at industrial facilities involved in the disposal of unprofitable natural gas."

As the World Bank, European Union, and others have been using satellites to track flaring—the burning of unwanted fossil gas—in an effort to reduce the harmful practice, fossil fuel producers have been adopting enclosed combustion technology to eliminate unwanted methane.

While the industry promotes enclosed combustors as a clean, safe, and efficient solution for eliminating unwanted emissions and ensuring regulatory compliance, critics claim they're a way for gas producers to conceal flaring—which releases five times more methane than previously believed, as Common Dreams reported in 2022.

"Enclosed combustors are basically a flare with an internal flare tip that you don't see."

"Enclosed combustors are basically a flare with an internal flare tip that you don't see," Tim Doty, a former regulator at the Texas Commission on Environmental Quality, told The Guardian. "Enclosed flaring is still flaring. It's just different infrastructure that they're allowing."

"Enclosed flaring is, in truth, probably less efficient than a typical flare," Doty added. "It's better than venting, but going from a flare to an enclosed flare... is not an improvement in reducing emissions."

Eric Kort, an associate professor at the University of Michigan, told The Guardian that "if you enclose the flare, people don't see it, so they don't complain about it."

"But it also means it's not visible from space by most of the methods used to track flare volumes," he added.

According to a March 2023 report published by the World Bank and Global Gas Flaring Reduction Partnership, an estimated 140 billion cubic meters of gas was flared globally in 2022, a 3% decrease from the previous year. The top 10 countries by flare volume that year were Russia, Iraq, Iran, Algeria, Venezuela, the United States, Mexico, Libya, Nigeria, and China.

Flaring releases carbon dioxide and toxic pollutants including carcinogenic chemicals. Despite these dangers, energy and environmental regulators allow the venting of fossil gas, which is up to 90% methane, into the atmosphere.

Methane—which has more than 80 times the warming power of carbon dioxide during its first two decades in the atmosphere—is emitted during the production and transportation of oil, gas, and coal, as well as from municipal landfills and livestock.

The International Energy Agency (IEA) published a report last October warning that immediate cuts to methane gas pollution caused by fossil fuel production are critical for limiting planetary heating to 1.5°C, the more ambitious objective of the Paris agreement.

The need is urgent. According to the U.S. National Oceanic and Atmospheric Administration, the three most critical heat-trapping gases in Earth's atmosphere—carbon dioxide, methane, and nitrous oxide—once again reached record levels last year, with methane increasing by 10 parts per billion to 1,922.6 ppb.

Responding to The Guardian's reporting, U.K. Green parliamentary candidate Catherine Read said that "oil and gas companies are hiding their 'flaring' operations because laws are being brought in to reduce emissions of [greenhouse gases] from waste gas that can't be sold at a profit."

"They don't care about us, our children, or nature," she added, "only profit above all else."
