Align sustainability narratives across [PortfolioBrands] to avoid contradiction and greenwashing risk while maximising differentiation. Map current claims, certifications [Certifications], and material topics (carbon, circularity, sourcing) vs stakeholder expectations [Stakeholders]. Define common principles and brand-specific proof points.
Output format:
Claims map (Markdown): Brand | Claim | Proof | Certification | Risk Level | Owner.
Portfolio narrative hierarchy: enterprise stance, category pillars, brand-level RTBs.
Gap/Risk register with remediation actions and timelines [Timeframe].
Measurement framework: KPIs (e.g., CO₂e/Unit, PCR %, supplier audit pass rate) and governance ([ESGLead], [Legal]).
