The mega-leaks occur across the world, but the top 25 list, produced by the Stop Methane Project at the University of California, Los Angeles (UCLA), is dominated by facilities in Turkmenistan. The scale of methane leaks in the secretive and authoritarian state has previously been described as “mind-boggling”.
Super-polluting plumes were also seen in the US, the largest detected in 2025 occurring in Texas and leaking 5.5 tonnes of methane per hour, equivalent to running about a million fuel-guzzling SUVs. Venezuela (five) and Iran (three) also had multiple mega-leaks from state-owned facilities.
So secretive that people have nick named ones. “The Gates of Hell” was started years ago they lit it and it’s finally starting to burn out 50 some odd years later.
I didn’t think they were supposed to be secrets…
