Ecosphere Engine is a seven-layer AWS-based sustainability intelligence platform that ingests corporate ESG disclosures, environmental LCA datasets, audit reports, and planetary boundary thresholds into a unified data repository. Data flows through preprocessing and normalization, then into a hybrid weighting engine combining Analytic Hierarchy Process (AHP) subjective weights with Shannon entropy objective weights via cooperative game theory to produce Pareto-optimal composites. The Weighted Sum Model scores Environmental, Social, and Governance indicators, applies logistic penalty functions near planetary tipping points, and validates results through Monte Carlo simulation and statistical testing before surfacing insights via interactive dashboards for investors, policymakers, and regulators. This architecture demonstrates how to operationalize complex multi-criteria decision analysis and scientific thresholds in a scalable cloud pipeline.
