Methane, the Climate Emergency Brake That Capital Markets Still Underprice

Methane occupies a distinctive position in the climate system. It is eighty times more powerful than carbon dioxide over a twenty-year horizon, responsible for roughly a third of the warming recorded since pre-industrial times, and short-lived enough that fast reductions translate into reduced warming within years rather than decades. Yet it attracts only two to three per cent of global climate mitigation finance, and agriculture, its single largest source, remains a structural blind spot in corporate disclosure, regulation, and investment analysis. Nusa Urbancic, CEO of Changing Markets Foundation, and François Mosnier, Head of Nature at Planet Tracker, present a comprehensive analysis of the financial materiality of methane in a 1FinanceWorld session hosted by Hamish Monk, Senior Reporter and Council Member at the Chartered Institute of Journalists. Urbancic and Mosnier frame the discussion not as an environmental appeal but as a hard financial case: methane is the climate emergency brake, the most cost-effective near-term lever available to regulators, investors, and corporate boards, and capital markets continue to underprice both the risk of inaction and the opportunity of action.

Methane as the climate emergency brake

Methane's strategic importance flows from its unusual combination of potency and short atmospheric lifetime. Because the molecule breaks down in the atmosphere within around twelve years, fast reductions in emissions translate into reduced warming within years rather than decades. Unlike carbon dioxide, which locks in temperature increases for centuries, methane offers the possibility of meaningful near-term course correction on timescales that match the horizons over which capital allocators plan, governments legislate, and corporate boards set strategy. This asymmetry between potency and persistence is the foundation of the financial case Urbancic and Mosnier build throughout the session.

Methane is currently responsible for around half a degree Celsius of warming, which is roughly a third of the temperature increase recorded since pre-industrial levels. Cutting it fast is therefore one of the few credible ways to slow the curve of near-term warming while longer-horizon decarbonisation of energy systems plays out. Despite this, only around two to three per cent of global climate mitigation funding flows into methane mitigation, which leaves one of the highest-leverage tools in the climate toolbox systematically underfunded.

The agricultural gap in methane mitigation

The policy and investor focus on methane has historically sat within the oil and gas sector, where leak detection, flaring rules, and equipment standards have driven early progress. The quieter and larger story sits in agriculture. François Mosnier, Head of Nature at Planet Tracker, notes that agriculture alone accounts for about forty-two per cent of global methane emissions today, making it the single largest contributor.

The mechanism is straightforward. Livestock digestion is the dominant driver, followed by manure management. Less widely appreciated is the role of rice paddies, which emit methane through anaerobic decomposition. The economic geography is also unfavourable for quick fixes. Agricultural methane is dispersed across smallholders, complex supply chains, and cross-border sourcing, which makes it harder to measure and harder to regulate than a concentrated oil and gas facility. The result is that agriculture is often described as an orphan in methane mitigation, despite being the sector with the largest absolute emissions.

Global Methane Pledge, progress and shortfall

The Global Methane Pledge was launched at COP26 in Glasgow and now has more than one hundred and fifty signatories committed to cutting global methane emissions by at least thirty per cent by 2030. Progress against that target is real but insufficient. Analysis released in the last year by UNEP and the Climate and Clean Air Coalition, which act as an informal secretariat for the pledge, found that if countries fully deliver the measures set out in their methane action plans and Nationally Determined Contributions, methane emissions would fall by around eight per cent by 2030.

Eight per cent is not thirty per cent, but it is the first time the curve is bending. If every technically feasible measure were implemented, the reduction would reach thirty-two per cent, in line with the pledge. Agriculture is the part of the system where the gap is most visible. Under current pathways, agricultural methane emissions would still rise by around four per cent by 2030 rather than fall, which is why the sector is described as an orphan in methane mitigation. The problem is not that the tools do not exist, but that neither regulation nor finance is directing them at scale.

A concentrated sector of outsized emitters

The agricultural sector can look diffuse from the outside, but at the top of the supply chain it is highly concentrated. Changing Markets mapped the largest meat and dairy companies and found that, despite limited disclosure by most producers, a small number of names emit methane at the scale of entire countries. The single largest corporate methane emitter identified is Brazilian beef producer JBS, whose methane footprint approaches the combined livestock emissions of four major livestock-producing countries. Marfrig, also Brazilian, has methane emissions comparable to the entire livestock sector of Australia. Tyson Foods, Nestlé, Danone, and Saputo appear further down the same ranking.

The comparison with the fossil fuel sector is instructive. The total carbon dioxide equivalent emissions of JBS are on a scale similar to a large oil major such as ConocoPhillips. Taken together, the methane footprint of the top meat and dairy companies is comparable to the total methane emissions of Russia, including its fossil fuel sector. This is a concentrated problem with concentrated solutions. Unlike the millions of farms that ultimately sit in their supply chains, these corporations have the balance sheet, the data infrastructure, and the procurement leverage to tackle methane at scale. The narrative shift that follows is important. Methane mitigation in agriculture is not primarily a smallholder responsibility, it is a large-corporate governance issue.

Early movers setting the standard

Progress exists and is accelerating in pockets. Changing Markets tracks corporate performance through its Methane Action Tracker, which currently ranks dairy and coffee brands alongside major retailers. Two dairy companies, Danone and Bel Group, have set explicit methane reduction targets. A wider group that includes Bel Group, Danone, Kraft Heinz, General Mills, Clover Sonoma, and Starbucks now discloses methane emissions in disaggregated form, which is the best-practice standard for making progress visible and comparable.

The Dairy Methane Action Alliance, run by EDF, now counts ten member companies, all of which commit to disclose methane emissions and publish an action plan for reducing them. Early measured reductions have been recorded at Bel Group, Kraft Heinz, and Nestlé. Danone, the first major food company to adopt a public methane target, committed to a thirty per cent reduction by 2030 and has reported in its most recent annual sustainability report that it is close to achieving that target five years ahead of schedule. Marfrig has become the first major meat processor to adopt a methane target, committing to a thirty-three per cent reduction by 2035. Taken together, these data points challenge the argument that agricultural methane is fundamentally hard to abate. Where companies set targets and disclose progress, reductions follow.

The financial materiality of methane

The case for treating methane as a material financial issue does not depend on environmental preference. Methane is a powerful near-term climate driver, which means unmanaged exposure amplifies transition, physical, and policy risk for any company or portfolio with material agricultural methane in its supply chain. As future carbon pricing, market screening by buyers and lenders, and reputational expectations converge, the cost of inaction rises on a compressed timeline.

The feedback loop is already visible in the United States beef industry, which is facing one of the worst drought crises in its history. Cattle inventory is at its lowest level in more than seventy years, driven by water stress and forage loss in the Great Plains, conditions that are very likely being amplified by climate change. Ranchers have liquidated herds early, which has tightened cattle supply into major processors. Tyson Foods has faced significant losses linked to reduced processing capacity and has idled plants as a result. A sector that emits large volumes of methane is now absorbing the financial consequences of the climate instability that methane helps accelerate.

For financial institutions, the implication is direct. Portfolio-level net zero commitments can be severely affected by the methane trajectory of a small number of companies, concentrated in meat, dairy, and rice. Methane deserves to be treated as a distinct risk factor rather than folded into an aggregate greenhouse gas exposure line.

How the financial sector can engage

Planet Tracker's engagement with banks and asset managers points to three concrete shifts. The first is to integrate methane explicitly into risk and portfolio management, map exposure to agricultural methane across the book, and treat it as a distinct risk factor inside credit risk analysis, equity research, and valuation models. Analysts typically focus on a handful of key drivers for any given company, and methane needs to sit inside that shortlist for meat, dairy, and rice-exposed issuers.

The second is to strengthen stewardship. That means pressing for separate methane disclosure, short and long-term reduction targets, and detailed abatement and capital expenditure plans, all of which reduce greenwashing risk and create a basis for comparing issuers. Stewardship also means voting accordingly and, where necessary, reallocating capital toward companies demonstrating credible plans.

This is not theoretical. Norges Bank Investment Management has been identified as the only large investor to explicitly reference the Global Methane Pledge and to embed methane expectations into its climate action plan, including direct engagement with companies in methane-intensive sectors. If one of the largest asset owners in the world can operationalise this, a long list of asset managers can follow the same template.

The third shift applies specifically to banks. Bank exposure to the sector runs through both lending and bond issuance facilitation, and the balance between the two is striking. Analysis of the twenty-five largest banks finds that ninety-six per cent of the capital they provided to the sector flowed through bond underwriting rather than direct loans. Most bank emissions targets, however, cover only the loan book. Extending coverage to bond financing is the single most important step in making bank climate commitments match the actual shape of their business.

Country-level action and agriculture exceptionalism

At country level, agriculture dominates methane in many of the largest producing jurisdictions. Livestock accounts for around fifty-four per cent of methane emissions in the European Union and around seventy-four per cent in Brazil. New Zealand is a particularly interesting case, since agriculture is the majority of its total emissions and the country was the only one with a specific methane target. That target has been weakened under a no-additional-warming approach, which treats short-lived methane as a stock to stabilise rather than a flow to reduce, and has been heavily criticised by climate scientists who see this as a missed opportunity.

More broadly, most major livestock-producing countries are not doing enough on methane. The reason is what Changing Markets calls agriculture exceptionalism, the phenomenon whereby a well-organised and politically connected farm lobby secures exemptions, voluntary measures, or subsidised technical and end-of-pipe solutions such as biogas and feed additives, while harder questions about consumption patterns are deferred. Of twenty-eight NDCs analysed, plus the European Union, only five include any reference to shifting diets toward lower meat and dairy consumption, namely Switzerland, Germany, Ireland, Mexico, and Norway. Only four per cent of NDCs include agricultural methane targets, and separate analysis by the Oxford Climate Policy Monitor finds that only eleven of thirty-seven jurisdictions reviewed have mandatory agricultural methane policies in place.

Europe's regulatory path forward

Europe's regulatory pipeline offers two particularly important openings. The first is the forthcoming revision of the National Emissions Ceilings Directive, which governs air pollution. Methane is not yet regulated as an air pollutant in Europe, despite being a precursor of ground-level ozone. Ozone exposure is linked to around seven thousand premature deaths in Europe and to damage to crop yields, with more than twelve per cent of European agricultural land currently exposed to unsafe ozone levels. Lobbying by the dairy industry and the powerful farm umbrella Copa-Cogeca has historically kept methane out of the air pollution framework, but the health and agricultural productivity case for inclusion is strong and politically harder to dismiss.

The second is the Effort Sharing Regulation, which covers sectors outside the EU Emissions Trading System, including transport, agriculture, and waste. As European climate targets tighten, agriculture and waste methane will need to be addressed directly rather than implicitly. Under CSRD, Scope 3 disclosure is required where material, and it is difficult to see how methane is not material for the relevant companies. Making that materiality test more prescriptive and enforceable would close a significant gap between rule and practice.

Subsidies sit alongside regulation. Agricultural subsidies in the sectors with the largest methane footprint are often not directed at reducing emissions. Reallocating even a portion of those flows toward scalable methane-reduction solutions in livestock and rice, many of which are still small and capital-constrained, would materially change the economics of mitigation. The European Scientific Advisory Committee has highlighted agriculture as a priority issue, including the need to price agricultural emissions and to support a reduction in meat and dairy overconsumption.

Priority actions for regulators, investors, and companies

Asked to identify the single most important lever, François Mosnier points to the conversations that portfolio managers and analysts already have with the CEOs and CFOs of methane-exposed companies. There are typically five to ten priorities discussed each quarter. Placing the demand for a strong, scientifically credible methane reduction plan at the top of that list, consistently and across the financial community, would itself be transformative. Consensus among long-term capital providers is a lever companies cannot ignore.

Nusa Urbancic identifies two complementary priorities. The first is regulation that requires companies to set science-based methane reduction targets and report against them, which, as Danone has shown, focuses management attention and can deliver faster progress than expected. The second is policy that implements the dietary shift already recommended by medical professionals and public health bodies. Modelling by Changing Markets indicates that if half the European population shifted to the healthier diets that are already officially recommended, methane reductions would comfortably exceed forty-five per cent, above the pledge level and consistent with scientific advice, while delivering significant health co-benefits and reducing the agricultural sector's dependence on pesticide and fertiliser inputs whose supply chains remain exposed to geopolitical disruption such as the recent tensions around the Strait of Hormuz.

The structures, the data, and the capital all exist. What is missing is the decision, at the level of regulators, investors, and corporate boards, to treat methane with the urgency its physics demand.
