Energy & Extractives IFRS Industry Guidance
Methane, reserves, transition risk, water, mine closure, and safety metrics for high-emitting sectors.
At 3:17 in the morning, a methane detector on an offshore platform in the North Sea triggered an alarm. The reading was 4.2 percent — well below the explosive threshold, but high enough to shut down operations. The platform manager called the onshore control room. "We have a leak," he said. "How big?" asked the engineer. "We don't know yet," the manager replied. "We know it's there. We don't know how much." That gap — between knowing a risk exists and quantifying it — is the defining challenge of the energy and extractives sector.
IFRS S2's industry-based guidance for energy and extractives covers oil and gas exploration and production, midstream operations, refining and marketing, oil and gas services, coal operations, construction materials, iron and steel, and metals and mining. Each industry has its own material disclosure topics: methane emissions for oil and gas, water stress for mining, transition risk for coal, reserves disclosure for exploration and production.
Under IFRS S2 §8–24, companies must describe how climate-related transition risks affect their business model. For an oil and gas company, this means disclosing reserves that may become stranded under a 1.5°C scenario. For a mining company, it means disclosing water usage in water-stressed regions. For a steel producer, it means disclosing the carbon intensity of production and the cost of transitioning to green hydrogen. The methane detector on the North Sea platform measured a number. IFRS S2 requires companies to measure the same thing at scale: not just that a risk exists, but how much of it there is.
Energy and extractives face the hardest transition — from measured physical risks to quantified stranded assets, all requiring disclosure under IFRS S2.
In Plain Language
Energy and extractives companies face the most capital-intensive climate transition in the global economy. IFRS S2 §8–24 requires companies to quantify transition risk exposure and disclose how a 1.5°C scenario affects asset valuations, reserves that may become uneconomic, and the resilience of the business model. Methane leaks from wellheads, pipelines, and processing facilities represent both an operational efficiency loss and a material Scope 1 emissions source under IFRS S2 §27 — requiring direct measurement and mitigation strategies aligned with the GHG Protocol. The ISSB codified SASB Standards for oil and gas exploration and production, midstream operations, refining and marketing, oil and gas services, coal operations, construction materials, iron and steel, and metals and mining. Each sub-industry carries distinct disclosure obligations: oil and gas companies must disclose methane emissions measurement methodology and reserve valuations under climate scenarios; mining companies must quantify water withdrawal in water-stressed regions and the financial impact of water scarcity on operations; coal operators must disclose transition risk exposure and asset retirement obligations. Under IFRS S1 §21–24, these physical and transition risks must be connected to the financial statements — explaining how stranded asset risk affects balance sheet valuations, how mine closure obligations create provisions and contingent liabilities, and how water stress impacts operational continuity. The methane detector on the North Sea platform measured a number. IFRS S2 requires companies to measure the same thing at scale: not just that a risk exists, but how much of it there is, what it costs, and how it changes the asset base.
- Energy and extractives face the hardest transition — from measured physical risks to quantified stranded assets, all requiring disclosure under IFRS S2.
- Methane emissions, stranded reserves, and water stress are the three metrics that define climate risk for energy and extractives — each with its own IFRS S2 disclosure requirement.
- The practical test is whether a company can show how much of its reserve base becomes uneconomic under a 1.5°C scenario — not as a scenario narrative, but as a quantified exposure.
Technical Requirements
- Methane emission measurement & mitigation — IFRS S2 §27: Companies must disclose Scope 1 greenhouse gas emissions using the GHG Protocol, including direct methane emissions from wellheads, pipelines, and processing facilities.
- Reserve valuation & stranded asset risk — IFRS S2 §8–24: Companies must describe how climate-related transition risks — including a 1.5°C scenario — affect asset valuations, reserves that may become uneconomic, and the business model.
- Water stress & biodiversity impact — IFRS S1 §21–24: Mining and extractives operations in water-stressed regions must disclose water withdrawal volumes, the impact on local ecosystems, and the financial implications of water scarcity.
- Mine closure & safety obligations — IFRS S1: Companies must disclose provisions and contingent liabilities for mine rehabilitation, tailings dam safety, and post-closure environmental monitoring.
