India Landfill Methane Emissions: Rising Climate Risk from Waste Sites
India Landfill Methane Emissions are becoming a major environmental concern as new global data highlights the impact of unmanaged waste. Two landfill sites in Telangana and Maharashtra have been listed among the world’s top 25 methane “super-polluters” in 2025. This finding comes from the “Spotlight on the Top 25 Methane Plumes in 2025: Landfills” report by the UCLA STOP Methane Project.

The report identified 25 landfill sites across 18 countries with the highest methane emissions. Using satellite data from Carbon Mapper, researchers tracked nearly 3,000 methane plumes from more than 700 waste sites worldwide.
These landfills were found to emit between 3.6 and 7.5 tonnes of methane per hour. A landfill near Buenos Aires was recorded as the highest emitter globally, releasing about 7.6 tonnes per hour.
Why Methane Emissions Are Dangerous
Methane is a powerful greenhouse gas that has a much stronger short-term warming effect than carbon dioxide. Even a single landfill releasing 5 tonnes of methane per hour can have the same climate impact as nearly one million SUVs.
In addition to climate change, these emissions also harm public health. Methane contributes to ground-level ozone, which can worsen air quality, especially in densely populated urban areas.
India’s Waste Challenge and Opportunity
According to the United Nations Environment Programme, the waste sector contributes around 20 percent of global human-caused methane emissions. India has one of the largest potentials in the world to reduce methane from waste due to its large volume of municipal garbage.
Simple and effective solutions include:
- Segregation of organic waste
- Capturing landfill gas
- Converting waste into energy
These steps are not only cost-effective but also help reduce pollution and improve urban living conditions.
India Landfill Methane Emissions: Global Push for Faster Action
The report aims to push governments and landfill operators to act quickly by making methane emissions visible through satellite monitoring. Countries like Brazil, Chile, Turkey, and India have multiple sites on the high-emission list.
Some progress is already visible. In Chile, landfill operators have started taking corrective steps after being identified in earlier reports. For India, stricter waste management systems and continuous monitoring will be important to reduce methane emissions and protect both climate and public health.
