Methane Super-Emitters Identified: Turkmenistan Tops Global List

Satellite Study Reveals Major Methane Hotspots Driving Climate Change

Recent satellite-based research has identified a small number of oil and gas sites responsible for disproportionately high methane emissions worldwide. The findings highlight the dominance of Turkmenistan as a major global hotspot, emphasising the urgent need to address concentrated emission sources to combat climate change.

Turkmenistan Emerges as Major Hotspot

The analysis reveals that Turkmenistan accounts for a large share of the world’s highest methane-emitting sites. Studies indicate that over two-thirds of the top 25 global “super-emitter” locations are concentrated in the country. Other hotspots include Iran, Venezuela, Texas in the United States, and Sindh in Pakistan. Satellite monitoring has detected thousands of methane plumes across oil and gas facilities, underscoring the scale of emissions.

High-Intensity Emissions and Their Causes

Methane super-emitters release large volumes of gas in short periods, often due to equipment leaks, poor maintenance, and inefficient flaring. Many of these emissions are preventable with better monitoring and timely repairs. Since methane is a valuable fuel (natural gas), capturing leaks can also be economically beneficial.

Why Methane Matters for Climate Change

Methane is a highly potent greenhouse gas with a much stronger warming effect than carbon dioxide in the short term. It contributes significantly to global warming, accounting for nearly 25–30% of current temperature rise. Despite its shorter atmospheric lifespan, reducing methane emissions is one of the fastest ways to slow climate change.

India Context: Landfills as Methane Sources

Apart from fossil fuel operations, methane is also emitted from landfills, agriculture, and wastewater. In India, landfill sites like Ghazipur landfill are major contributors due to decomposition of organic waste under anaerobic conditions. This highlights the need for improved waste management and methane capture systems.
