การปรับให้สอดคล้องกับ GRI / SASB / ISSB

GRI and ISSB are complementary, not competing. GRI 2021 focuses on impact materiality — how the company’s activities affect people, the environment, and society. The audience is broad: stakeholders, communities, civil society, employees. ISSB (IFRS S1 + S2) focuses on financial materiality — how sustainability topics affect the company’s enterprise value, cash flows, and access to capital. The audience is narrower: investors, lenders, financial analysts.

Most SET-listed companies need both. ISSB is the regulatory disclosure (becoming Thai SEC mandate under the IFRS Roadmap); GRI is the broader sustainability narrative (the standard for sustainability reports). The master cross-walk shows how to disclose the same underlying data once, reusable across both frameworks. Materiality service → covers the double-materiality methodology that grounds this in advance.

The Task Force on Climate-related Financial Disclosures (TCFD) was subsumed under IFRS S2 in 2024. The TCFD itself was dissolved as a standalone body, with the Financial Stability Board transferring oversight responsibilities to the IFRS Foundation. Going forward, all new climate-related disclosure should be drafted to IFRS S2 — which incorporates TCFD’s four-pillar framework (governance, strategy, risk management, metrics & targets) as its structural foundation.

TCFD remains relevant in cross-walks for two reasons: (1) legacy disclosure continuity — companies that have published TCFD-aligned disclosure for multiple cycles need a clear reconciliation showing how prior TCFD pillars map to IFRS S2 sections; (2) certain rating agencies and lenders still reference TCFD framing in their questionnaires. Othello’s cross-walk preserves the TCFD column as a reconciliation reference rather than a separate disclosure target.

Both are sector-specific overlays on a general sustainability framework — but they’re built differently. SASB Industry Standards sit under ISSB and define financial-materiality KPIs for 77 industries classified under SICS (Sustainable Industry Classification System). SASB’s emphasis is on quantitative metrics that affect enterprise value. GRI Sector Standards sit under GRI 2021 and define impact-materiality topics for specific sectors — currently published for Oil & Gas (GRI 11), Coal (GRI 12), Agriculture & Aquaculture (GRI 13), with Mining (GRI 14) in development.

The two are complementary: a single oil & gas company should apply both GRI 11 (for the sustainability report) and SASB Extractives & Minerals Processing standard (for investor disclosure). The master cross-walk maps disclosures to both. SICS classification is distinct from GICS / ICB — Othello determines the correct SICS industry at engagement intake.

Two ways. First, duplicate disclosure work is eliminated. Without a master cross-walk, the same underlying KPI (e.g., Scope 2 GHG emissions) typically gets re-disclosed for each framework’s submission, often with subtle inconsistencies. Each submission cycle (FTSE, CDP, MSCI, DJSI, Sustainalytics) ends up re-deriving the same data. With the master cross-walk, the canonical disclosure is drafted once and reused across submissions. Typical savings: 30–40% of duplicate disclosure work.

Second, audit defensibility improves. Rating agencies and external auditors regularly challenge disclosure inconsistencies between a company’s sustainability report, its 56-1 ESG section, its CDP submission, and its TCFD/IFRS S2 climate disclosure. Inconsistencies trigger downward score adjustments at FTSE and MSCI. The master cross-walk surfaces these inconsistencies upfront and provides the canonical source-of-truth.

FTSE Russell methodology is the 2026 SET ESG scoring standard. It applies to all 868 SET-listed companies. FTSE assesses 14 themes across 300+ indicators, ICB-weighted by sector. Othello’s cross-walk includes a dedicated FTSE column — every disclosure KPI mapped to the FTSE indicator(s) it satisfies. This is structurally different from the ESG Gap Analysis service (which scores existing disclosure against FTSE).

The cross-walk service is the methodological foundation — once the master cross-walk is built, the gap analysis runs against it to produce the indicator-by-indicator scoring. For SET-listed companies entering the FTSE Russell scoring regime, the workflow is typically: (1) cross-framework alignment → (2) gap analysis → (3) disclosure remediation → (4) bilingual reporting.

Thailand Taxonomy Phase 1 covers Energy + Transport sectors, issued jointly by BOT, SEC, and DEPA. It defines what economic activities qualify as climate-aligned for sustainable finance purposes (green bonds, sustainability-linked bonds, sustainability-linked loans). Aligned with the ASEAN Taxonomy structure and structurally similar to the EU Taxonomy. Phase 2 (Manufacturing, Agriculture, Construction) is in development.

For SET-listed corporates issuing sustainable finance instruments, Thailand Taxonomy alignment is increasingly required by Thai institutional investors and is the entry point for ASEAN green bond market issuance. The Deep Tier cross-walk includes a dedicated Taxonomy column showing which company activities map to which Substantial Contribution criteria. EU Taxonomy alignment is included for SET-listed companies with EU institutional shareholders or EU subsidiaries. Sustainable Finance service →

Different cadences. IFRS Foundation publishes occasional amendments to S1 and S2 (S2 had its first amendment in 2024); new standards in development include biodiversity-related disclosure (S3) and human capital (S4). GRI publishes new Sector Standards on a rolling basis (Mining GRI 14 in development, Textiles in research). SASB standards are stable but ISSB Application Guidance evolves. FTSE Russell publishes annual methodology refresh (v3.5 most recent). EFRAG publishes new ESRS topical standards (E5, S1–S4 published; sector-specific ESRS in development).

The Maintenance Protocol deliverable establishes a monitoring approach for these updates. Refresh Tier engagements are typically commissioned when a material standard update affects the cross-walk. For most SET-listed companies, the practical cadence is a full refresh every 2–3 years (sync’d with materiality refresh) with a Refresh Tier maintenance engagement in between years where standards updates are material.

Yes — that’s the Deep Tier scope. Post-M&A cross-walk consolidation is more complex than a simple merger of two companies’ framework references because: (1) SICS industry classification may shift for the combined entity, changing which SASB standards apply; (2) GRI Sector Standards application may change if the merger introduces new sector activities; (3) FTSE ICB sector weighting may shift, changing which themes carry highest weight; (4) climate scenarios and physical risk exposure change with geographic footprint.

For group structures (parent + multiple subsidiaries), the Deep Tier produces both a consolidated group-level cross-walk and entity-level cross-walks for subsidiaries that report separately. Common scenarios: parent company at SET, subsidiaries in regional markets requiring separate disclosure; SET-listed REIT/IFF holding portfolio companies; SET-listed energy holding with renewable and conventional subsidiaries. Engagement intake clarifies the reporting boundary first.

Yes. Othello responds to formal procurement processes for cross-framework alignment from SET-listed corporates, post-M&A integration teams, sustainable finance issuers, and procurement teams scoping larger ESG advisory engagements. Standard procurement requirements are met: ISO 17100:2015 certification, ATA + ATC accreditation, GDPR + PDPA compliance, mutual NDA from first email, in-house framework-issuer credentials (GRI 2021 Trainer, IFRS Foundation, AA1000AS ACSAP, ISO 14064 Lead Auditor, TGO Auditor), SASB SICS industry trained, and SET-listed engagement references available under mutual NDA at procurement stage.

Standard RFP response is 3–5 วันทำการ. RFP response covers: methodology approach (8-framework mapping with credentialled assessor per framework), tier recommendation per scenario, in-house bench credentials, capacity allocation, pricing structure, engagement timeline, and sample cross-walk excerpt (anonymised). Quote response on engagement scoping is within one business hour of receipt of source files and signed NDA.
