This study examines relationships between environmental management efforts and corporate performance based on databases on financial items in Japan using ten years of financial data for Japanese listed 227 firms and ten years of environmental management scores from Nikkei Research’s "Environmental Management Score Survey" report. We have constructed a scalable data analysis pipeline using these databases for ten years. As a result, we clarified some positive correlations between environmental management efforts and corporate performance. Specifically, we found the statistical significance of the Product Measures in the environmental management efforts for financial performance. Our data analysis method with a systemic pipeline helps design an ESG investment portfolio.
