What's New in ESG Reporting for 2026?
ESG reporting in 2026 is undergoing significant transformation. Malaysia's Bursa Malaysia continues enhanced sustainability reporting for public listed companies. Singapore's MAS has implemented ISSB-aligned standards effective FY2026, requiring comprehensive climate-related disclosures. The EU's CSRD expands to second-wave companies, while Australia introduces phased Scope 3 disclosure requirements.
Most significantly, 2026 marks a shift from voluntary to mandatory, audit-ready disclosures—with regulators and investors demanding evidence-based data validation rather than estimates.
Key changes in 2026:
- Singapore: MAS ISSB-aligned disclosure (FY2026 effective)
- Australia: AASB Scope 3 phased disclosure begins
- Malaysia: Bursa enhanced Scope 3 requirements continue
- EU: CSRD second wave implementation
- Global: ISSA 5000 assurance standard adoption
What is ESG Reporting?
ESG reporting is the practice of measuring, disclosing, and communicating a company's environmental, social, and governance (ESG) performance to stakeholders including investors, regulators, customers, and employees.
ESG stands for:
- Environmental: Climate impact, emissions, resource use, pollution
- Social: Labor practices, diversity, community relations, human rights
- Governance: Board structure, ethics, compliance, transparency
ESG reporting provides stakeholders with standardized information about how companies manage sustainability risks and opportunities. Unlike traditional financial reporting, ESG covers non-financial metrics that increasingly impact long-term business value, regulatory compliance, and access to capital.
For Malaysian companies, ESG reporting has evolved from voluntary disclosure to a regulatory requirement under Bursa Malaysia's Enhanced Sustainability Reporting framework. Companies must now provide evidence-bas
ed, audit-ready ESG data meeting both local requirements and international standards like ISSB.
Why ESG Reporting Matters in 2026
Regulatory Requirements
Malaysia: Bursa Malaysia requires public listed companies to disclose material ESG metrics, including Scope 1, 2, and phased Scope 3 emissions. Bank Negara Malaysia has issued climate risk guidelines for financial institutions requiring financed emissions disclosure.
Global Landscape:
- US: California SB-253 requires Scope 1-3 disclosure for companies with $1B+ revenue
- EU: CSRD mandates comprehensive ESG reporting with third-party assurance
- Singapore: MAS ISSB-aligned standards effective FY2026
- Australia: AASB Scope 3 disclosure phased for large entities
Business Impact
Access to Capital: Institutional investors managing trillions require comprehensive ESG data before investing. Companies with poor ESG reporting face higher capital costs and reduced access to ESG funds.
Risk Management: ESG reporting identifies climate risks, supply chain vulnerabilities, and governance weaknesses before they become material problems.
Competitive Advantage: Strong ESG performance attracts customers, employees, and partners who prioritize sustainability. ESG leadership differentiates companies in competitive markets.
The Three Pillars of ESG

- Water consumption and management
- Waste reduction and recycling
- Sustainable sourcing
- Circular economy practices
Social (S)
Workforce:
- Diversity, equity, and inclusion
- Employee health and safety
- Fair wages and labor practices
- Training and development
Community and Human Rights:
- Supply chain labor standards
- Community engagement
- Product safety and quality
- Data privacy and security
Governance (G)
Leadership and Ethics:
- Board independence and diversity
- Executive compensation alignment
- Anti-corruption measures
- Risk management
Accountability:
- Shareholder rights
- Transparent reporting
- Stakeholder engagement
- Regulatory compliance
ESG Reporting Standards and Frameworks
International Standards
- ISSB (International Sustainability Standards Board): Global baseline for sustainability disclosure, focused on financially material information. Adopted by Singapore, Malaysia (phased), Australia, and many jurisdictions.
- GRI (Global Reporting Initiative):Comprehensive framework covering environmental, social, and economic impacts. Used by over 10,000 organizations globally for stakeholder-focused reporting.
- TCFD (Task Force on Climate-related Financial Disclosures):Framework for climate-related financial risk disclosure covering governance, strategy, risk management, and metrics. Widely incorporated into regulatory requirements.
Regional Standards
- ESRS (European Sustainability Reporting Standards): Mandatory under EU CSRD, requiring double materiality assessment and comprehensive ESG coverage.
- Bursa Malaysia Framework: Enhanced sustainability reporting aligned with TCFD and transitioning to ISSB standards, with sector-specific requirements for high-impact industries.
The Data Validation Challenge
Why Data Quality Matters
While most platforms focus on calculating ESG metrics, the critical challenge in 2026 is ensuring data is credible, verifiable, and audit-ready.
- The Trust Gap: High-profile greenwashing cases have eroded trust in self-reported ESG data. Stakeholders now demand evidence-based validation, not just calculated figures.
- Assurance Requirements: New requirements under CSRD, ISSB, and Bursa Malaysia mean ESG data must meet the same rigor and auditability as financial data. Third-party assurance requires traceable evidence.
- Investor Needs: Institutional investors need confidence-scored ESG data to assess risk and make allocation decisions. Low-quality data creates investment risk and reduces access to capital.
Common Data Quality Issues
- Scope 3 Emissions: Value chain emissions rely on supplier data that's often estimated, incomplete, or unverified. Without evidence-linked data, Scope 3 figures lack credibility.
- Inconsistent Methodologies: Companies using different calculation methods produce non-comparable ESG metrics, making benchmarking and peer analysis difficult.
- Missing Documentation: Many companies can calculate ESG metrics but can't prove the underlying data when auditors request evidence trails.
The Solution: Validation-First Approach
Rather than focusing solely on calculation, leading companies in 2026 prioritize:
- Evidence-Based Data: Linking every ESG metric to source documents (invoices, bills, contracts, supplier declarations) that auditors can verify.
- Confidence Scoring: Assigning confidence levels to each data point based on source quality, helping stakeholders understand data reliability.
- Audit Trails: Creating immutable records of data sources, calculations, and changes to enable third-party assurance.
- AI-Powered Validation: Using technology to automatically validate data against frameworks like ISSA 5000, flag anomalies, and ensure regulatory alignment.
Frequently Asked Questions
1. What should be in an ESG report?
An ESG report should include material environmental metrics (emissions, energy, water, waste), social metrics (workforce diversity, safety, community impact), and governance metrics (board composition, ethics, risk management). It must also cover strategy, targets, progress, and risks.
2. Is ESG reporting mandatory in Malaysia?
Yes, ESG reporting is mandatory for Bursa Malaysia public listed companies. Requirements include material sustainability matters, Scope 1-2 emissions, and phased Scope 3 emissions disclosure. Third-party assurance will be required in future phases.
3. What's the difference between ESG reporting and sustainability reporting?
ESG reporting focuses on environmental, social, and governance factors material to financial performance and investor decisions. Sustainability reporting is broader, covering all impacts on society and environment regardless of financial materiality. Many frameworks now require both perspectives (double materiality).
4. How often should companies report ESG data?
Most regulations require annual ESG reporting aligned with financial reporting cycles. However, leading companies provide quarterly updates on key metrics and real-time data dashboards for continuous stakeholder engagement.
5. What is ISSA 5000?
ISSA 5000 is the international standard for sustainability assurance, providing requirements for auditors verifying ESG data. It ensures consistent, rigorous third-party verification of sustainability information, similar to financial audit standards.
Conclusion
ESG reporting in 2026 is no longer optional—it's a regulatory requirement and business necessity. As Malaysia, Singapore, Australia, and jurisdictions worldwide implement mandatory disclosure frameworks, companies must move beyond basic calculation to evidence-based, audit-ready ESG data.
Key Takeaways:
- ESG reporting covers environmental, social, and governance performance
- Regulations in 2026 require mandatory, assured ESG disclosures
- Malaysian PLCs must comply with Bursa's enhanced reporting framework
