The Short Game: Methane, CO2, and the Political Economy of Which Gas Gets Regulated

As five LNG carriers rerouted around the Strait of Hormuz on 17 April 2026, and as Rybar's English-language channel noted that the United States had again permitted purchases of Russian oil due to the "ongoing crisis," the term "natural gas" appeared repeatedly in market dispatches as a commodity whose flow was being disrupted and whose price was rising. What was notably absent from those dispatches — and from most of the political conversation around energy security and LNG infrastructure — was any acknowledgement of the atmospheric physics that distinguishes natural gas from other fossil fuels: its primary component, methane, is approximately 80 times more potent as a greenhouse gas than CO2 over a 20-year horizon, and approximately 30 times more potent over a century. The IPCC's Sixth Assessment Report found that atmospheric methane concentrations have more than doubled since pre-industrial times, with the rate of increase accelerating over the past decade. The single largest anthropogenic source is the fossil fuel sector — including the natural gas extraction, processing, and distribution infrastructure whose geopolitical disruption has dominated global energy news for the past week.

The gap between what atmospheric science says about methane and what energy policy does about it is not a knowledge problem. It is a political economy problem. Understanding it requires the frameworks that Naomi Klein applies to climate denial and delay, that Andreas Malm applies to the fossil capital system, and that Samir Amin applies to the structural interests that shape which environmental costs are internalised into market prices and which are externalised onto communities and the atmosphere. Kate Raworth's doughnut framework asks whether economic activity remains within safe planetary boundaries — and atmospheric methane concentration is a planetary boundary indicator whose trajectory is moving in the wrong direction, partly because the political economy of natural gas has successfully positioned LNG as a "transition fuel" in ways that delay both the measurement and the regulation of its methane leakage rate.

The Transition Fuel Fiction

The natural gas industry's central political claim over the past two decades has been that gas is a "bridge fuel" — cleaner than coal, facilitating the transition to renewables by providing dispatchable power that complements intermittent solar and wind. This claim depends entirely on the leakage rate of methane from gas infrastructure. If leakage from wells, pipelines, LNG liquefaction plants, regasification terminals, and distribution networks exceeds approximately 2 to 3 percent of total gas produced (depending on the time horizon used for comparison), natural gas is not cleaner than coal on a climate basis over the coming decades when the methane forcing matters most for near-term temperature trajectory.

Multiple studies using satellite methane detection — including data from the GHGSat constellation and, more recently, the MethaneSAT mission — have found leakage rates substantially higher than industry self-reporting suggested. The Environmental Defense Fund's analysis of Permian Basin operations found leakage rates in the 3 to 9 percent range at individual facilities. A 2022 study published in Science found that US LNG export facilities emit methane at rates 24 times higher than the EPA's regulatory estimates. These findings do not appear in the dispatch guidance of energy ministers announcing LNG supply agreements with European partners seeking to replace Russian pipeline gas — agreements whose expansion of LNG infrastructure represents a multi-decade commitment to methane-emitting supply chains.

The CO2 Fixation and Its Beneficiaries

Climate policy's overwhelming CO2-centricity is not arbitrary. Carbon pricing mechanisms — emissions trading systems, carbon taxes, carbon offsets — are most easily designed for CO2 because CO2 is released in combustion events that are metered and recorded. Methane is released through leaks, venting, flaring, and biological processes across diffuse source categories that are difficult to monitor at the facility level and even more difficult to attribute to specific operators. The monitoring infrastructure required to regulate methane is more expensive to build and more threatening to existing operators than the monitoring infrastructure for CO2 — and the industries that would bear the regulatory burden are the same industries with the greatest lobbying power in the political systems that design climate policy.

Global South political history analysis of how the institutions of global governance serve the interests of capital is applicable here. The UN's methane monitoring frameworks rely heavily on national self-reporting, which in turn relies heavily on industry self-reporting. The Global Methane Pledge, launched at COP26 and joined by over 150 nations, commits signatories to a 30 percent reduction in methane emissions by 2030 — but it is non-binding, carries no verification mechanism with genuine enforcement, and its implementation architecture defers substantially to the very industry it seeks to regulate. Martinez-Alier's political ecology of environmental valuation would identify this as a case where the costs of an environmental impact are systematically undervalued in policy frameworks because the actors who would bear regulated costs have greater power over the valuation process than the communities who bear the unregulated impacts.

The Hormuz–Methane Connection

The current crisis provides an instructive illustration of how fossil fuel geopolitics and methane policy interact. European governments, still managing the transition from Russian pipeline gas that the Ukraine war accelerated, have contracted for additional LNG supply from the United States, Qatar, and Australia to reduce their dependence on a single supplier. Each new LNG supply agreement requires infrastructure: liquefaction capacity at the export terminal, cryogenic shipping, regasification capacity at the import terminal. Each piece of that infrastructure has a characteristic methane leakage profile. The infrastructure investments committed to in the aftermath of the Ukraine war represent decades of methane-emitting operations. They cannot be rapidly unwound if the atmospheric science on methane leakage rates proves as unfavourable as recent satellite data suggests — and the geopolitical context of energy security has been invoked, with considerable success, to dismiss climate concerns about LNG infrastructure expansion as unaffordable idealism.

This is the political economy of methane regulation in its clearest form: crisis creates urgency that overrides precaution, infrastructure commitments create lock-in that outlasts the crisis, and the atmospheric consequences of those commitments accumulate in the background while policy attention moves to the next emergency. The communities in the Global South who are most exposed to the near-term temperature forcing that methane drives — Bangladesh, sub-Saharan Africa, Pacific island nations — have the least leverage over the LNG infrastructure decisions being made in Brussels, Tokyo, and Washington.

Near-Term Temperature and the 20-Year Horizon

The most consequential political choice embedded in methane versus CO2 policy is the choice of time horizon. CO2's effects are long-term and cumulative; methane's are front-loaded. Atmospheric methane persists for roughly 12 years before oxidising — meaning that methane emitted today produces its maximum warming effect within the next decade and then diminishes. Aggressive methane reduction is therefore the fastest available lever for limiting near-term temperature overshoot, which matters enormously for the survival of coral reef systems, polar ice sheets, and monsoon patterns on which billions of people depend.

The choice to centre climate policy on CO2 rather than on a dual-gas framework that takes methane seriously is, from an atmospheric physics perspective, a choice to prioritise the long-term trajectory over the near-term crisis. It is also, from a political economy perspective, a choice that is more comfortable for the natural gas industry. Andreas Malm would note that this comfort is not incidental: fossil capital does not passively accept the regulatory frameworks that threaten its assets. It actively shapes those frameworks through the political mechanisms — lobbying, campaign finance, the revolving door between industry and regulatory agencies — that a structural analysis of media incentives names under the categories of ownership, advertising, and sourcing. The atmospheric science of methane is not disputed. The political will to act on it is missing precisely because acting on it would threaten the asset base of one of the most politically powerful industries in the world.

Monexus chose the methane angle because it is the climate story most consistently suppressed by the energy security framing that dominates coverage during commodity price shocks — and because the near-term temperature implications of methane policy choices are the most direct threat to the communities the Global South climate justice movement represents.
