Before diving into individual requirements, this lesson maps the complete architecture of IFRS S2: its objective, scope, four disclosure pillars, and the key defined terms you will encounter throughout the standard.
The Objective of IFRS S2
IFRS S2's objective is stated in paragraph 1: to require an entity to disclose information about its climate-related risks and opportunities that is useful to primary users of general purpose financial reports in making decisions about providing resources to the entity.
Two elements of this objective are critical:
- "Useful to primary users": IFRS S2 is not an environmental regulation. It does not require companies to change how they manage climate risks. It requires companies to disclose information so that investors, lenders, and insurers can make better decisions about allocating capital.
- "Could reasonably be expected to affect the entity's prospects" (paragraph 2): This is the materiality threshold. An entity need only disclose climate information that a reasonable investor would consider relevant to the entity's cash flows, access to finance, or cost of capital over the short, medium, or long term. Risks and opportunities that cannot reasonably be expected to affect the entity's prospects are outside the scope of IFRS S2 (paragraph 4).
Think of it this way: IFRS S2 does not tell you how to drive the car. It tells you to turn on the headlights so other drivers (investors) can see where you are going.
The Scope: Three Categories
IFRS S2 covers three categories of climate-related matters (paragraph 3):
- Climate-related physical risks: Risks from the physical effects of climate change (for example, flooding, heat stress, sea-level rise)
- Climate-related transition risks: Risks from the shift to a lower-carbon economy (for example, carbon pricing, technology disruption, changing demand)
- Climate-related opportunities: Potential positive effects from climate change or the transition (for example, new markets for low-carbon products)
The Four Disclosure Pillars
Everything in IFRS S2 is organised into four pillars, mirroring the TCFD structure:
| Pillar | Paragraphs | Core Question |
|---|---|---|
| Governance | 5 to 7 | Who is responsible for overseeing climate risks and how? |
| Strategy | 8 to 23 | How do climate risks and opportunities affect strategy and financial performance? |
| Risk Management | 24 to 26 | How does the entity identify, assess, and manage climate risks? |
| Metrics and Targets | 27 to 37 | How does the entity measure and track its climate performance? |
Key Defined Terms (Appendix A)
IFRS S2 defines 18 terms in Appendix A. These definitions are precise and must be applied consistently across disclosures. Here are the most important ones:
| Term | Definition (Simplified) |
|---|---|
| Climate-related physical risks | Event-driven (acute) or long-term shift (chronic) risks from climate change effects |
| Climate-related transition risks | Risks from transitioning to a lower-carbon economy: policy, legal, technology, market, reputational |
| Climate resilience | Capacity to adjust to climate-related changes, manage risks, and benefit from opportunities |
| Climate-related transition plan | An aspect of overall strategy laying out targets, actions, and resources for transitioning to a lower-carbon economy |
| Greenhouse gases (GHGs) | Seven gases per the Kyoto Protocol: CO2, CH4, N2O, HFCs, NF3, PFCs, SF6 |
| CO2 equivalent (CO2e) | Universal unit using global warming potential (GWP) to compare GHGs against CO2 |
| Global warming potential (GWP) | Radiative forcing impact of one unit of a GHG relative to one unit of CO2 over 100 years |
| Scope 1 GHG emissions | Direct emissions from sources owned or controlled by the entity |
| Scope 2 GHG emissions | Indirect emissions from purchased electricity, steam, heating, or cooling |
| Scope 3 GHG emissions | Indirect emissions in the entity's value chain (upstream and downstream), excluding Scope 2 |
| Financed emissions | Portion of GHG emissions of investees or counterparties attributed to an entity's loans and investments |
| Internal carbon price | Price used to assess financial implications of changes; either a shadow price (notional) or an internal fee or tax |
| Carbon credit | Emissions unit from a carbon crediting programme representing an emission reduction or removal; uniquely serialised and tracked |
The Seven Cross-Industry Metric Categories
Within the Metrics and Targets pillar, IFRS S2 requires all entities to disclose seven cross-industry metric categories (paragraph 29), regardless of sector:
| # | Category | What It Covers |
|---|---|---|
| (a) | Greenhouse gases | Absolute Scope 1, 2, and 3 emissions in tCO2e |
| (b) | Transition risk exposure | Amount and percentage of assets or activities vulnerable to transition risks |
| (c) | Physical risk exposure | Amount and percentage of assets or activities vulnerable to physical risks |
| (d) | Climate-related opportunities | Amount and percentage of assets or activities aligned with opportunities |
| (e) | Capital deployment | Capex, financing, or investment toward climate risks and opportunities |
| (f) | Internal carbon prices | Whether and how a carbon price is used; price per tonne |
| (g) | Remuneration | Whether and how climate considerations feature in executive pay |
Think of IFRS S2 as a structured interview about climate risk. The four pillars are the main questions: "Who's in charge? What's your strategy? How do you manage risk? How do you measure it?" The cross-industry metrics are the mandatory numerical answers. Every entity must provide them, just like every company must report revenue and profit.
Key Takeaways
- 1IFRS S2 is a disclosure standard requiring transparency, not a regulation telling entities how to manage climate risk
- 2The standard covers three categories: physical risks (acute and chronic), transition risks (policy, legal, technology, market, reputational), and climate-related opportunities
- 3Seven cross-industry metric categories apply to every entity regardless of sector: GHG emissions, transition risk exposure, physical risk exposure, opportunities, capital deployment, internal carbon prices, and remuneration
- 4Appendix A defines 18 precise terms including the seven Kyoto Protocol greenhouse gases, CO2 equivalent, and financed emissions
- 5The materiality threshold is whether information could reasonably be expected to affect the entity's prospects over the short, medium, or long term
