Technical report presents a multivariate framework assessing ESG impact in investment portfolios in overseas territories, suggesting improved evaluation methods.
This Technical Report PC-TR-2026-01 presents IMPACT-OM™ (Multi-criteria Performance and Climate-Territory Adequacy Index — Overseas), a structured scientific methodology for the typological characterization of ESG impact applied to investment portfolios in the French overseas territories (DROM-COM). The framework reorganizes published statistical techniques (Factor Analysis of Mixed Data, Ward ascending hierarchical clustering, K-means consolidation, validation by five statistical indices under a parsimony constraint) within an original combination, calibrated for mixed ESG data (quantitative, ordinal, nominal, binary) with partial missingness typical of overseas financing files. The document is published in English and French within a single record and follows a four-level epistemic tagging system ([ESTABLISHED] / [ADAPTED] / [PROPRIETARY] / [OPEN]) distinguishing public scientific content from proprietary parameter settings retained by Plannova Consulting.
