NEW YORK CITY – The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea has led to what is likely the single-biggest release of methane ever recorded, the United Nations Environment Programme said on Friday.
A huge plume of highly concentrated methane was detected in an analysis this week of satellite imagery by researchers associated with UNEP’s International Methane Emissions Observatory, or IMEO, the organization said.
“This is . . . most likely the largest emission event ever detected,” Manfredi Caltagirone, acting head of the IMEO for UNEP, told Reuters. “This is not helpful in a moment when we absolutely need to reduce emissions,” he said.
Researchers have not yet been able to quantify from the imagery the amount of methane leaking from the Gazprom-led pipeline system, but they believe that the rate of emissions is higher than from a major leak that occurred in December from offshore oil and gas fields in Mexican waters of the Gulf of Mexico, which spilled around 100 metric tons of methane per hour, Caltagirone said.
The Gulf of Mexico leak, also viewable from space, ultimately released around 40,000 metric tons of methane over 17 days, according to a study conducted by the Polytechnic University of Valencia and published in the journal Environmental Science & Technology Letters.
Improved satellite technology has rapidly enhanced the ability of scientists to find and analyze greenhouse gas emissions in recent years, something some governments hope will help companies detect and prevent methane emissions.
The major leaks that suddenly erupted in the Nord Stream gas pipelines that run from Russia to Europe have generated plenty of theories but few clear answers about who or what caused the damage. Both Russia and the European Union have suggested the ruptures were caused by saboteurs.
