The world is hemorrhaging natural gas through preventable methane leaks that have reached near-record levels, according to a new International Energy Agency report—a crisis that reveals how inadequate environmental oversight is costing energy-dependent nations billions of cubic metres of fuel they desperately need.
The IEA's global methane tracker 2026 report found that methane emissions from the energy sector remained at near record levels in 2025. The agency concluded that implementing tried-and-tested abatement measures could make 200 billion cubic metres of natural gas available annually—a staggering volume that underscores how much energy is being wasted through leaks rather than delivered to markets.
The scale of the problem is most acute in countries where regulatory oversight is weakest. In March, the Guardian reported on some of the world's worst mega-leaks of the potent greenhouse gas in 2025, with satellite analysis by the Stop Methane Project at the University of California, Los Angeles identifying mega-leaks occurring around the world. The top 25 list was dominated by facilities in Turkmenistan, where the scale of methane leaks has previously been described as "mind-boggling."
The Human and Economic Cost
The consequences extend far beyond climate impact. With the war in the Middle East squeezing energy supplies, the leaked gas represents a critical resource gap for importing countries. The IEA found that if select countries with spare existing gas export capacity and importing countries implemented readily accessible methane abatement measures across their gas systems, nearly 15 billion cubic metres of gas could very quickly be made available to markets.
Over the longer term, such measures could deliver nearly 100 billion cubic metres of gas to markets each year, while eliminating non-emergency gas flaring could unlock a further 100 billion cubic metres. These figures demonstrate that the energy crisis afflicting nations worldwide has a significant preventable component—one rooted in insufficient regulation and enforcement.
The largest detected mega-leak in 2025 occurred in Texas and leaked 5.5 tonnes of methane per hour, equivalent to running about a million fuel-guzzling four-wheel drives. Venezuela and Iran also had multiple mega-leaks from state-owned facilities, revealing that the problem spans both authoritarian and democratic systems, though with varying degrees of transparency and accountability.
Landfills and the Waste Management Gap
The Stop Methane Project also analysed super-polluting plumes from landfill sites, where rotting organic waste can release huge volumes of methane when not well managed. The worst sites were across the world, from Turkey to Algeria and Malaysia to the US, indicating that this is not merely a problem of energy infrastructure but of waste management systems that lack adequate public investment and oversight.
Accountability Questions Linger
Turkmen officials claimed in October that methane mega-leaks had been reduced. Muhammetberdi Byashiev, the head of the environmental protection department at the state company Türkmengaz, said, "Management has placed this under special control, and leaks are being repaired locally within two to three days," citing collaboration with the UN, IEA and EU.
However, the analysis showed that substantial mega-leaks continued despite these claims, raising questions about enforcement mechanisms and the adequacy of international cooperation frameworks. The gap between stated commitments and measurable outcomes highlights the need for stronger regulatory architecture and independent monitoring systems.
Why This Matters:
This methane crisis illustrates a fundamental market failure: without robust public regulation and enforcement, energy companies and waste management operators lack sufficient incentive to prevent leaks that cost them nothing while imposing costs on society. The billions of cubic metres of gas being wasted represent resources that could ease energy shortages for vulnerable populations facing higher heating and electricity costs. The concentration of mega-leaks in countries with weaker environmental governance and transparency demonstrates how inequality in institutional capacity creates global consequences. As energy supplies tighten due to geopolitical conflict, the case for stronger international standards, public oversight, and mandatory reporting becomes not merely an environmental imperative but an economic and social justice issue affecting energy security for nations worldwide.
