IFRS S1 addresses value chain coverage + use of estimates + time horizons + and reporting practical implementation. (1) Value Chain Considerations: an entity shall consider sustainability-related risks and opportunities arising throughout its value chain (upstream + downstream) + including direct operations + activities and resources used + customer use + employees + supplier base + outsourced activities. The value chain encompasses interactions + resources + and relationships an entity uses + or affects + to create its products or services + including those between the entity and other related parties + such as suppliers + customers + employees + value chain influence on third-parties. (2) Use of Estimates and Outcome Uncertainty: where measurement of sustainability-related impact involves estimates + entity shall disclose (a) qualitative information about sources of uncertainty + sensitivity to assumptions; (b) quantitative information about uncertainty where reasonably available; (c) explanation of judgements applied; (d) consistency with sustainability assumptions + financial assumptions. Estimates inherent to many sustainability metrics + including GHG emissions calculations + scenario analysis + transition assumptions. (3) Time Horizons: entity shall apply short + medium + and long time horizons + as relevant to industry + business model + and sustainability topic. Short-term typically refers to next reporting period (1-2 years) + medium-term (3-10 years) + long-term (>10 years). Time horizons may vary by industry (e.g. utilities longer horizons for infrastructure planning + technology shorter horizons for product cycles). (4) Comparative Information: prior period comparative information disclosed + restated for prior period errors + retrospective application of new IFRS Sustainability Disclosure Standards (subject to transition reliefs). (5) Estimate Methodologies + Climate Scenarios: where assumptions disclosed + including (a) Paris Agreement-aligned scenarios (1.5 C + 2 C + 3 C); (b) IPCC Representative Concentration Pathways (RCPs); (c) IEA International Energy Agency Net Zero by 2050; (d) Network for Greening the Financial System (NGFS) climate scenarios; (e) International Renewable Energy Agency (IRENA) scenarios. (6) Transition Reliefs (first-year applies): (a) IFRS S1 + S2 transition relief from disclosing comparative information; (b) relief from quantitative scope 3 emissions disclosures for first year (S2); (c) relief from sustainability topics other than climate-related for first year (S1); (d) relief from reporting interim sustainability information. Entity shall use transition reliefs only as permitted + disclose use. (7) Periodicity: entity shall disclose comparative information for at least one prior period + may extend to multiple periods for trend analysis. Coordinates with IFRS Accounting Standards + IFRS S1 paragraphs + IAS 8 Accounting Policies Changes in Accounting Estimates and Errors + IPCC Reports + Paris Agreement scenarios + IEA NZE 2050 + NGFS scenarios. IFRS S1 Value Chain + Estimates + Time Horizons applies.
