- The “Spotlight on the Top 25 Methane Plumes in 2025: Landfills” report, released by the University of California, Los Angeles, identified the top global methane-emitting waste sites.
- Report lists 25 landfill sites across 18 countries with the highest methane emissions (3.6–7.6 tonnes/hour), based on satellite data.
- India’s Jawahar Nagar landfill in Telangana (5.9 tonnes/hour) ranked 4th, and Kanjurmarg landfill in Mumbai (4.9 tonnes/hour) ranked 12th globally.
- Data analysed nearly 3,000 methane plumes from over 700 waste sites using satellites like NASA EMIT and Carbon Mapper.
- Landfills contribute about 20% of global methane emissions, making them a key target for climate action.
- Methane is 86 times more heat-trapping than carbon dioxide (CO₂) and causes over 45% of recent global warming.
