Using satellite data, the researchers mapped the huge plumes of methane emitted by human activities.
According to a new study, satellite images show methane plumes released by oil and gas facilities during leaks or maintenance operations, accounting for about 8% to 12% of total methane- dissolve emissions from oil and gas, according to a new study.
Study co-author Riley Duren, a research scientist at the University of Arizona and CEO of Carbon Mapper, a nonprofit that works to monitor and reduce methane and carbon dioxide emissions, said in a statement.
“In a pivotal decade for climate action, this highlights the urgent need for durable global observation systems that can detect, identify and quantify methane emissions at large scales.” involved in decision making,” Duren said.
Methane is the second most common greenhouse gas emit into The earthatmosphere behind carbon dioxide, and is more damaging to the climate than carbon dioxide in the short term. According to the newspaper MIT . Climate Portal.
To measure the amount of methane emitted by human activities around the world between 2019 and 2020, the researchers studied atmospheric methane images produced by the Atmospheric Monitor. created by the European Space Agency. SentinelSatellite -5P, daily measurement of atmospheric methane.
The researchers found that about 1,200 (about two-thirds) of the visible “super-emissions” – the source that generates more than 27.5 tonnes (25 tonnes) of methane per hour – comes from oil production and gas, while the remaining one-third According to the study, is split between coal, agriculture and waste management.
Methane released during oil and gas production can be the result of planned maintenance operations and unexpected equipment malfunctions or leaks.. Turkmenistan has the highest estimated methane emissions for the study period, followed by Russia, the United States, Iran, Kazakhstan and Algeria. However, the researchers were unable to measure methane plumes in areas like the Permian basin of the United States or oil production in Canada and China because the total emissions in these regions are too high to generate out each micro-emission, The New York Times reported.
According to the study, stopping these methane plumes by enforcing leak detection or reducing methane emissions during maintenance would be equivalent to removing 20 million vehicles from the world. road for a year.
The findings were published on February 3 in the journal Science.
