GBCPGreen Building Certifications

% of {legal_name}'s portfolio covered by a recognized green-building certification scheme. EXTRACTION RULES: Recognized schemes include (NON-EXHAUSTIVE examples, agnostic to region) LEED, BREEAM, CASBEE, GBC Italy, DGNB, HQE, Green Star, Estidama, IGBC, NABERS, and any equivalent national/regional scheme. Cite a scheme registry OR the company sustainability / ESG report OR the annual report (any reporting format qualifies; do NOT restrict to a standalone ESG report or a single US/LEED registry). ZERO HANDLING (CLAUDE.md #2/#4/#5): a genuine 0% (the company explicitly states it has no green-certified buildings, OR you performed a registry / ESG-report lookup that came back empty AND you cite that checked source) is a LEGITIMATE value → return value:0 and it scores 25. But if the figure is simply NOT FOUND (no ESG/registry/annual-report source was located and checked), return absent (not_disclosed) — NEVER return 0, and NEVER estimate or fabricate a number. The cited source distinguishes a real 0 from a not-found. Return exact_numerical{value: <pct>, source_urls: [registry / report URLs checked]}. Ratio_band (<10→25, 10-30→50, 30-60→70, 60-85→85, 85+→95).
