Performance Analysis of Japanese Electric Vehicle Manufacturers in Environmental, Social, and Governance Using Text Mining and Predictive Methods

The value of environmental, social, and governance (ESG) has been increasingly emphasized across various industries, particularly in the automotive sector, where its importance has become especially prominent. In this study, the environmental initiatives of Japanese electric vehicle (EV) manufacturers were evaluated from an ESG perspective. Leading Japanese companies in EV production, such as Toyota, Nissan, and Honda, were included in the analysis. Using text mining techniques on sustainability and CSR reports from the past five years, key environmental keywords were extracted, and word clouds were generated to visualize the trends in each company’s environmental efforts. A correlation analysis was conducted between the frequency of environmental keywords and CO2 emissions data. Based on past trends in keywords and emissions data, predictive analysis was performed to analyze the potential for future emissions reductions and the strategic direction of each company’s sustainability initiatives.
