A small number of massive methane leaks around the world are releasing huge volumes of greenhouse gases, raising fresh concerns about their role in accelerating global warming. The findings, based on satellite data, show that these so-called mega leaks are contributing significantly to global heating and are largely linked to oil and gas operations and waste sites. Scientists say many of these leaks are preventable and could be fixed with existing technology. Yet, despite growing awareness and international commitments, the data suggest that major emissions continue to go unchecked in several regions, raising concerns about missed opportunities to slow warming in the near term.
Mega leaks concentrated in a few regions
The study, carried out by researchers at the University of California, Los Angeles as part of the Stop Methane Project, shows that a relatively small number of sites account for a large share of global methane emissions. Using satellite data, the analysis identified major leak hotspots in countries such as Turkmenistan, the United States, Venezuela and Iran, where oil and gas infrastructure and waste sites are releasing methane at unusually high rates. In some cases, individual facilities were found to emit methane at levels comparable to large industrial sources.
The UCLA Stop Methane analysis, based on data from Carbon Mapper, identified around 4,400 significant methane plumes in 2025, each releasing more than 100 kilograms per hour, roughly equal to emissions from about 20,000 SUVs. In the United States, nine of the 10 largest methane leaks were detected in Texas, pointing to concentrated emission hotspots. One of the largest leaks recorded released about 5.5 tonnes of methane per hour, an amount scientists say is comparable to emissions from around one million vehicles, highlighting the outsized role of these super-emitting sites in driving global methane pollution
Methane’s powerful role in global heating
Methane is a short-lived but highly potent greenhouse gas. Scientists estimate that it is responsible for about a quarter of the warming currently being experienced globally, making it a critical target for climate action.
Unlike carbon dioxide, methane breaks down more quickly in the atmosphere, which means reducing emissions can deliver relatively fast climate benefits. Researchers say that cutting methane leaks could slow the rate of warming in the near term, providing valuable time for longer-term transitions to cleaner energy systems.
Despite this, the persistence of large leaks suggests gaps between commitments and action. Many of the identified emissions come from infrastructure that could be repaired or upgraded without major technological challenges. In some cases, captured methane could even be sold as natural gas, making leak prevention economically viable.
Fixing leaks offers a fast climate solution
Experts involved in the analysis stress that addressing methane leaks is one of the quickest ways to limit global temperature rise. Compared to other climate measures, repairing leaks and improving monitoring systems can deliver immediate reductions in emissions.
Advances in satellite technology are playing a key role in this effort. New tools allow scientists to track methane plumes in near real time and pinpoint the exact location of leaks. This growing transparency is making it harder for major emitters to avoid scrutiny and is increasing pressure on governments and companies to act.
However, researchers warn that stronger enforcement and international cooperation will be needed to translate data into action. While some regions are introducing regulations to curb methane emissions, large leaks continue to occur, particularly in areas with limited oversight. The findings suggest that tackling these high-impact sources could make a meaningful difference in slowing global heating in the coming years.
