Overview of Methane Emissions
Methane is a potent greenhouse gas, trapping 28 times more heat in the atmosphere than carbon dioxide over a century. It is responsible for approximately one-third of global warming, making its reduction critical for climate change mitigation. A recent analysis by the Stop Methane Project at the University of California, Los Angeles (UCLA) has identified the top 25 oil and gas sites with the highest methane emissions worldwide, revealing significant leaks primarily concentrated in Turkmenistan.
Major Methane Emitters
The analysis utilized data from Carbon Mapper, which employs remote sensing technology to quantify methane emissions. The findings indicate that 15 of the 25 largest methane leaks are located in Turkmenistan, with the two largest emitters operated by the national energy companies Türkmennebit and Türkmengaz in Esenguly, each releasing over 10 metric tons of methane per hour in 2025. The United States has one site on the list, located in Stanton, Texas, emitting 5.5 metric tons per hour, equivalent to the emissions from about one million SUVs.
Implications of Methane Emissions
Reducing methane emissions is essential for slowing global warming. A 45% reduction could potentially lower global temperatures by approximately 0.3 °C by 2045, according to the Global Methane Assessment. This reduction could also prevent 260,000 premature deaths from air pollution and save billions of hours of labor lost to extreme heat. Experts emphasize that addressing methane emissions is a more immediate strategy compared to carbon dioxide reductions, which require longer-term efforts.
Challenges in Addressing Methane Leaks
Despite the clear need for action, challenges remain, particularly in Turkmenistan, where the government has claimed a 60% reduction in methane emissions in 2023. However, experts argue that significant leaks persist, and the lack of transparency complicates regulatory efforts. The fossil fuel industry's reliance on methane extraction further complicates the situation, as many countries struggle to enforce emissions limits and repairs.
Proposed Solutions and Global Initiatives
Experts suggest that cutting methane emissions is both effective and cost-efficient, with two-thirds of necessary reductions achievable at zero net cost. Simple infrastructure upgrades and improved maintenance practices could significantly reduce emissions from existing sites. The European Commission is taking steps to combat methane emissions through new regulations and the creation of a Methane Transparency Database, while Canada has strengthened its methane regulations for oil and gas producers.
Approximately 160 countries have joined the Global Methane Pledge, committing to a 30% reduction in methane emissions by 2030. The collaborative efforts of governments, industries, and NGOs are essential to achieving these targets and mitigating the impacts of climate change.

- “Durwood Zaelke, President of the Institute for Governance and Sustainable Development, said: “Cutting methane is the single most important strategy to slow near-term warming.” — Durwood Zaelke, President of the Institute for Governance and Sustainable Development
- “Americans should be surprised and angered by the fact that the US lands pretty high on this list of top super-polluting plumes. We in the US tend to think of our industry as fairly well and cleanly run, but this shows that we still have work to do.” — Cara Horowitz, Executive Director of the Emmett Institute on Climate Change and the Environment at UCLA School of Law
Conflicting Reports & Gaps
While the Turkmenistan government claims a significant reduction in methane emissions, independent analyses suggest that major leaks continue to be a problem. The discrepancy between reported reductions and observed emissions highlights the need for improved transparency and accountability in methane reporting.
