Regulators are no longer asking companies only for historical emissions figures. They want to know how a business would hold up under 1.5°C, 2°C, or higher-warming futures. Climate scenario analysis has moved from a niche risk management exercise to a disclosure expectation.
This shift is happening because the ISSB's IFRS S2 explicitly requires scenario analysis disclosure, and SEBI's BRSR Core framework is increasingly aligning with global norms. Investors and lenders are starting to ask companies how climate change could affect cash flows, asset values, and supply chains over the next decade and beyond.
This article explains what climate scenario analysis actually involves, why regulators are pushing for it, and how companies, even those without dedicated climate risk teams, can begin building this capability.
Article Section
Climate scenario analysis is a structured exercise that models how a company's operations, assets, and financial performance would be affected under different plausible future climate pathways, typically drawing on scenarios developed by bodies like the IPCC, IEA, or NGFS (Network for Greening the Financial System).
The analysis covers two core risk categories: physical risks, including acute events like floods and cyclones and chronic shifts like rising average temperatures or water stress, and transition risks, including policy changes, carbon pricing, shifting consumer demand, and technology disruption as the economy moves toward lower emissions.
Scenario analysis is not a single forecast or prediction. It is a stress test across multiple plausible futures, commonly a low-warming scenario aligned with the Paris Agreement, a high-warming scenario reflecting limited policy action, and one or more intermediate pathways, used to identify where a company's strategy is resilient and where it is exposed.
Article Section
The ISSB's IFRS S2 climate standard explicitly requires companies to disclose how resilient their strategy is under different climate scenarios, including at least one consistent with limiting warming to 1.5°C. This is rapidly becoming the global reference standard that other regulators, including SEBI, look to when shaping domestic requirements.
Central banks and financial regulators globally, through bodies like the NGFS, have started treating climate risk as a source of financial system instability, not just an environmental issue. This reframing is what is driving disclosure requirements into mainstream financial regulation rather than keeping them siloed in sustainability reporting.
Annual emissions figures tell investors what happened. Scenario analysis tells them what could happen to enterprise value under different futures. Institutional investors managing long-duration capital increasingly treat this forward-looking view as essential to underwriting climate-related financial risk.
Regulators have grown skeptical of net zero commitments unsupported by evidence that a company has actually tested its strategy against the climate pathways it claims to be navigating. Scenario analysis provides that evidence, or exposes its absence.
Article Section
Full quantitative modelling requires significant data and capability most companies do not yet have. A qualitative exercise, where leadership teams map out how operations, supply chains, and revenue could be affected under defined warming scenarios, is a credible and recognised starting point.
Companies do not need to develop original climate scenarios. Established frameworks from the NGFS, IEA, and IPCC provide ready-to-use pathways covering physical and transition risk variables that can be applied directly to a company's specific context.
Rather than attempting an enterprise-wide analysis immediately, companies can prioritise the facilities, supply chain nodes, or business lines most likely to face physical climate exposure or transition disruption, and expand scope over time.
Companies that begin scenario analysis now, even informally, will be better positioned as IFRS S2-aligned disclosure expectations tighten in India, rather than scrambling to produce a credible analysis under regulatory deadline pressure.
Article Section
Climate scenario analysis is no longer an advanced or optional exercise reserved for companies with dedicated climate risk teams. It is becoming a core expectation of credible climate governance, reflected directly in global disclosure standards and increasingly in domestic regulatory frameworks.
Companies that start with a structured, even simplified, scenario exercise now will be far better positioned than those waiting for full regulatory clarity, both in terms of disclosure readiness and in genuinely understanding where their business is exposed to climate-related risk.
Article Section
Climate scenario analysis models how a company's strategy and financials would perform under different future climate pathways, while a carbon footprint assessment measures current or historical emissions.
IFRS S2 requires scenario analysis disclosure so that investors can assess how resilient a company's strategy is under different climate futures, including a pathway consistent with limiting warming to 1.5°C.
Physical risk covers climate-driven events like floods or rising temperatures, while transition risk covers business impacts from policy changes, carbon pricing, and shifts toward a lower-emissions economy.
No, companies can begin with a qualitative exercise that maps exposure under defined warming scenarios before building quantitative modelling capability.
Companies commonly use scenarios from the NGFS, IEA, and IPCC, typically combining a low-warming, high-warming, and intermediate pathway.
