The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea have led to what is likely the biggest single release of climate-damaging methane ever recorded, the United Nations Environment Programme said on Friday.
A huge plume of highly concentrated methane, a greenhouse gas far more potent but shorter-lived than carbon dioxide, 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 really bad, most likely the largest emission event ever detected,” Manfredi Caltagirone, head of the IMEO for UNEP, told Reuters. “This is not helpful in a moment when we absolutely need to reduce emissions.”
Researchers at GHGSat, which uses satellites to monitor methane emissions, estimated the leak rate from one of four rupture points was 22,920 kilograms per hour. That is equivalent to burning about 630,000 pounds of coal every hour, GHGSat said in a statement.
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.
