Reuters: The landfill in Istanbul is one of the world's largest methane emission points

Satellite observations show that Istanbul’s Seymen landfill, west of the city, emits an average of 7.4 tonnes of methane per hour, making it one of the world’s largest point sources of the gas. Turkey ranks fifth globally for methane emissions from solid waste, and the findings have renewed scrutiny of landfill gas leaks ahead of COP31. The release matters because methane traps far more heat than CO2 over the short term, so uncontrolled landfill emissions complicate Turkey’s climate targets. Watch for whether authorities announce capture or flaring upgrades at Seymen and other major sites, and whether the issue features in Turkey’s COP31 agenda.
