Play 69 — Carbon Footprint Tracker
AI-powered carbon tracking — Scope 1 (direct fuel), Scope 2 (location + market-based electricity), Scope 3 (AI-classified spend-based estimation), emission factor database (GHG Protocol 2024), multi-framework reporting (GHG Protocol/CDP/TCFD), reduction recommendations with ROI, and complete data lineage for audit.
