Practical IFRS S1 and IFRS S2: A Step-by-Step Guide to Sustainability and Climate-Related Financial Disclosures (IFRS in Practice)

Practical IFRS S1 and IFRS S2: A Step-by-Step Guide to Sustainability and Climate-Related Financial Disclosures is a technical and practice-focused book written for professionals who need a clear route through the new ISSB reporting framework. The book centres on IFRS S1, the general requirements for sustainability-related financial disclosures, and IFRS S2, the topic-specific standard for climate-related financial disclosures. It presents the standards as an integrated reporting system built around governance, strategy, risk management, and metrics and targets.This guide is designed for accountants, auditors, ESG reporting teams, CFOs, finance managers, sustainability officers, board members, consultants, analysts, regulators, advanced students, and anyone involved in corporate reporting, assurance, or financial communication. It explains the purpose, scope, architecture, and logic of IFRS S1 and IFRS S2 in a structured way, moving from the foundations of the standards into practical disclosure issues such as materiality, reporting boundaries, connectivity with financial statements, greenhouse gas emissions, climate scenario analysis, resilience assessment, internal controls, implementation systems, and model disclosures.Many books on ESG and sustainability reporting remain broad, narrative, or shaped around voluntary reporting language. This book takes a different route. It treats IFRS S1 and IFRS S2 as financially oriented disclosure standards aimed at existing and potential investors, lenders, and other creditors. It shows how sustainability-related risks and opportunities enter reporting because they affect enterprise prospects, cash flows, access to finance, and cost of capital. It also explains how climate-related disclosure under IFRS S2 extends far beyond general environmental commentary and requires disciplined reporting on physical risks, transition risks, climate-related opportunities, transition planning, financed effects, and emissions across Scope 1, Scope 2, and Scope 3.Readers will find step-by-step coverage of the central disclosure pillars. Governance sections explain oversight responsibilities, mandates, competencies, reporting lines, and accountability. Strategy sections examine business model effects, value chain exposure, decision-making, trade-offs, and resilience. Risk management sections address identification, assessment, prioritisation, monitoring, and integration with enterprise risk systems. Metrics and targets sections explain how disclosures move from narrative statements into measurable evidence. The book also studies the links between sustainability-related disclosures and the financial statements, helping readers understand why consistency of assumptions, timing, reporting entity alignment, and cross-referencing matter in practice.A major strength of this guide lies in its practical structure. It does not stop at conceptual explanation. It deals with implementation, internal reporting processes, data collection, validation, documentation, audit readiness, management roles, board involvement, first-year adoption issues, disclosure drafting, frequent reporting errors, comparative information, restatements, and future reporting direction. This makes it useful not only for study, but also for active reporting work inside companies, advisory firms, and assurance teams.The book is highly relevant for organisations preparing for ISSB-based reporting, listed entities strengthening climate-related financial disclosures, consultants supporting sustainability reporting projects, and academic readers who need a rigorous but readable reference. It is also useful for teams working across IFRS sustainability disclosure standards, corporate governance, climate risk reporting, ESG assurance, sustainability accounting, and integrated annual reporting.
