Introduction to ISSB Standards
The International Sustainability Standards Board (ISSB) has developed global baseline sustainability disclosure standards that will transform how companies report climate and ESG information. This comprehensive guide explains the ISSB standards, their relationship to Australian requirements, and how organisations can prepare for adoption.
The ISSB standards represent a major step toward global sustainability reporting harmonisation. By establishing a common language for ESG disclosure, the ISSB aims to make sustainability information more comparable and decision-useful for investors worldwide.
ISSB Standards Overview
The ISSB has issued two primary standards: IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures). Together, these standards provide a comprehensive framework for sustainability reporting.
IFRS S1: General Requirements
IFRS S1 establishes the foundation for all sustainability disclosures. It requires companies to disclose sustainability-related risks and opportunities that could reasonably be expected to affect the company prospects. The standard emphasises connectivity with financial statements.
Companies must provide disclosures about governance, strategy, risk management, and metrics and targets. These four pillars mirror the TCFD framework, ensuring consistency with existing practice. The standard requires sustainability information to be prepared with the same rigor as financial statements.
IFRS S2: Climate Disclosures
IFRS S2 specifically addresses climate-related disclosures. It requires companies to disclose climate-related risks (physical and transition) and opportunities. The standard follows the TCFD structure, making implementation more straightforward for companies already following TCFD recommendations.
Key disclosure requirements include governance oversight of climate issues, strategy and decision-making considering climate, risk management processes for climate risks, and metrics used to assess climate-related matters. Targets and progress against them must also be disclosed.
Global Adoption Landscape
ISSB standards are being adopted worldwide at different speeds. Several jurisdictions have committed to adopting or aligning with ISSB, while others are developing their own frameworks that incorporate ISSB principles.
International Progress
The United Kingdom has announced plans to adopt ISSB standards fully by 2025. The European Union has incorporated ISSB standards into its Corporate Sustainability Reporting Directive. Japan and Singapore have also signalled intention to adopt or align with ISSB.
Asia-Pacific Adoption
Australia is aligning AASB S2 with ISSB standards, ensuring Australian companies can meet both domestic and international requirements. Other Asia-Pacific jurisdictions are at various stages of ISSB adoption consideration.
Relationship with Australian Requirements
Australia AASB S2 is closely aligned with ISSB IFRS S2. This alignment ensures Australian companies can meet both Australian and international expectations through a single reporting process. Understanding the relationship between these standards is essential for effective preparation.
AASB S2 and ISSB Alignment
AASB S2 incorporates the ISSB requirements while adding Australian-specific provisions where necessary. The core disclosure requirements are consistent, enabling companies to prepare once and satisfy multiple reporting obligations. This approach reduces reporting burden while ensuring comprehensive disclosure.
Dual Reporting Benefits
Companies reporting under AASB S2 can easily adapt their disclosures for international purposes. The common foundation in TCFD and ISSB ensures consistency across jurisdictions. This efficiency is particularly valuable for multinational companies operating in multiple markets.
Governance Disclosures
Both ISSB and AASB S2 require robust governance disclosures. Companies must explain how the board and management oversee sustainability matters. This requirement ensures appropriate accountability for climate and ESG issues.
Board Oversight
Disclose which board committee(s) have oversight of sustainability matters. Describe the board competence and how it monitors climate issues. Explain how the board considers climate in strategic decision-making.
Management Processes
Explain management role in assessing and managing climate risks. Describe the organisational structures and controls in place. Report on how management is incentivised to consider climate matters.
Strategy Disclosures
The strategy disclosure requirements are comprehensive. Companies must explain how climate affects business models, strategy, and financial planning. This disclosure demonstrates how organisations are positioning for the low-carbon transition.
Business Model Impact
Describe how climate-related risks and opportunities affect the business model. Explain how the business model might change in different climate scenarios. This analysis should cover revenue, costs, assets, and liabilities.
Strategic Decisions
Disclose how climate considerations affect strategic decisions. This includes capital allocation, R&D spending, and market positioning. Companies should explain how climate scenarios inform their strategy.
Transition Planning
Explain the transition plan toward a lower-carbon economy. Include specific actions, timelines, and resource allocation. The transition plan should be consistent with disclosure of metrics and targets.
Risk Management
Climate risk must be integrated into enterprise risk management. The disclosure should explain processes for identifying, assessing, and prioritising climate risks. This integration ensures climate receives appropriate attention alongside other business risks.
Risk Identification
Describe processes for identifying climate-related risks. This includes both physical and transition risks. Explain how risks are categorised and prioritised.
Risk Assessment
Disclose how climate risks are assessed for likelihood and impact. Explain the methods and assumptions used. Quantify material risks where possible.
Metrics and Targets
Comprehensive metrics disclosure is a key requirement. Companies must disclose greenhouse gas emissions, climate-related metrics, and progress against targets. The emphasis on quantifiable data enhances comparability and accountability.
Greenhouse Gas Emissions
Disclose Scope 1, Scope 2, and material Scope 3 emissions. Use the GHG Protocol methodology. Ensure emissions are calculated consistently over time.
Climate-Related Metrics
Disclose metrics relevant to the business and industry. This may include energy consumption, water usage, or other environmental metrics. Metrics should be industry-appropriate and material to the business.
Targets and Performance
Set science-based targets aligned with the Paris Agreement. Disclose targets for emission reduction and other climate metrics. Report progress against targets annually.
Scenario Analysis
Scenario analysis is a critical requirement. Companies must use scenario analysis to inform strategy and assess climate resilience. The analysis should consider different climate pathways and their business implications.
Scenario Development
Develop scenarios representing different climate futures. Use established scenario frameworks such as NGFS or IPCC scenarios. Ensure scenarios are relevant to the business and geographic context.
Using Scenario Results
Explain how scenario analysis informs strategy and risk management. Disclose the key insights from scenario analysis. Show how the organisation is positioning for different climate futures.
Implementation Guidance
Preparing for ISSB disclosure requires systematic approach. Organisations should assess current capabilities, identify gaps, and develop an implementation roadmap.
Gap Assessment
Conduct a comprehensive gap assessment against ISSB requirements. Identify data, systems, and governance gaps. Prioritise actions based on materiality and effort.
Capability Building
Develop internal capabilities for sustainability reporting. This includes data collection, analysis, and disclosure preparation. Consider training and external expertise where needed.
System Development
Establish systems for collecting and reporting required data. Ensure data quality and consistency. Implement controls appropriate for sustainability information.
Conclusion
ISSB standards represent the future of global sustainability reporting. Australian companies should prepare for comprehensive climate and ESG disclosure. Early action will ensure more effective and credible reporting.
