Turkey will host Cop31, the annual United Nations climate conference, later this year, with methane emission reduction positioned as a central priority on the nation’s agenda. However, satellite monitoring has identified multiple large-scale methane leaks emanating from Turkish waste facilities, presenting a contradiction to the country’s stated climate commitments.
The Silivri municipal landfill near Istanbul represents the most significant methane source identified in Turkey. Researchers at the University of California used satellite data to measure emissions from the facility at approximately 7.4 tonnes per hour, ranking it among the most substantial landfill methane sources globally. The environmental impact of this single site’s leak is comparable to emissions from 1.5 million sport utility vehicles operating continuously. A second major facility in Şile, also serving the Istanbul area, releases approximately 4 tonnes of methane hourly. UCLA researchers identified ten high-emitting landfill sites across Turkey, describing the emission rates as exceptionally large when measured against international standards. Local residents living near these sites have reported persistent odor problems severe enough to force closure of windows during warm weather.
Staff at the Silivri facility acknowledged the emissions when presented with satellite imagery but characterized the current situation as improved compared to historical conditions in the 1990s. The facility extracts 6,000 cubic metres of methane hourly for energy generation. Officials attributed visible emissions to uncovered waste areas and stated that covering exposed sections represents a priority.
Turkey’s first lady has been active in promoting waste reduction and methane cuts internationally, while the country’s leadership has emphasized waste management improvements. The timing of these revelations occurs as Turkey prepares to convene global leaders for climate negotiations later this year.
