P09 — Regulatory Stack Alignment SCD-P09  ·  Principle 9 of 10 Regulatory Stack Alignment “Build once, report everywhere.” Governance Layer Definition Sovereign climate data must be structured from inception to satisfy multiple simultaneous regulatory requirements without re-engineering. The 2026 regulatory stack includes: EU Green Claims Directive (enforcement September 2026), CBAM embedded carbon verification (fully operational January 2026), ISSB S2 mandatory disclosure (Brazil CVM, Mexico CNBV, Chile CMF — all from 2026), CSRD third-country scope (2029), Article 6 Paris Agreement carbon market rules (finalised COP29, 2025), and domestic NDC reporting requirements across LATAM. Rationale Organisations that build data infrastructure aligned to only one regulatory standard face costly rebuilds as additional mandates come into force. The 2026 stack creates immediate, simultaneous exposure across multiple jurisdictions for most LATAM organisations with international operations or finance. CBAM alone creates direct financial penalties — not just reputational risk — for LATAM exporters of steel, cement, aluminium, fertilizers, and hydrogen who cannot verify embedded carbon. Article 6 rules (COP29, Belém 2025) mean sovereign data is now a prerequisite for participating in international carbon markets. Implementation Steps Audit your regulatory exposure: which of the 2026 stack applies to your organisation? Map each regulatory requirement to specific data fields (see Regulatory Mapping Table below). Design data collection to capture all required fields from the start — not retrofit. Use ISSB S2 as the baseline (it has the broadest adoption) and layer CBAM and GCD requirements on top. Review the stack annually: add new requirements as they come into force.
