Thesis: Tilted global equity portfolio toward clean energy leaders using Yuki's multi-factor ESG model, which screens for carbon transition readiness, governance quality, and innovation capex. Added 12 clean energy and efficiency companies, removed 8 high-carbon intensity names. Portfolio tracking error increased by only 15bps within risk budget. Result: +2.1% excess return over 12 months, driven primarily by renewable energy sector outperformance and carbon credit appreciation. Dissent note: Two IC members flagged concentration risk in a single thematic, overruled by CIO and risk committee.
