This study investigates the effects of Bloomberg’s ESG (Environmental, Social, and Governance) disclosure scores — both overall and by individual pillars — on Tobin’s Q as a proxy for financial performance among mining companies in Pacific Alliance countries from 2015 to 2023. The analysis incorporates control variables including commodity share price, firm size, debt, and leverage, using a panel data pooled mean-group estimation approach, except for Colombia, where time-series data from only one firm was available. The findings indicate that Mexican companies align with the stakeholder theory, in which enhanced sustainable performance contributes positively to financial performance. In this context, ESG disclosure serves as a green signal in the stock market, when the share price is non-signal market. In contrast, firms in Peru, Chile, and Colombia appear to adhere more closely to shareholder theory, wherein increased ESG transparency is associated with a decline in Tobin’s Q, although share price emerges as the primary market signal positively influencing Tobin’s Q. All variables were found to contribute to a long-run equilibrium relationship for each company, except for the Colombian case. Based on our findings, we recommend that companies primarily guided by shareholder interests enhance their sustainable environmental, social, and governance (ESG) practices. This involves strengthening ESG disclosure strategies, adopting green technologies to reduce emissions and mitigate the environmental impact of tailings, and integrating ESG considerations into financial planning processes. Furthermore, promoting their listing on ESG-focused stock indices can help support the development of regulated ESG markets.</div></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"4 2","pages":"Article 100301"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145694333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phase Change Materials (PCM) integrated into photovoltaic (PV) systems offer a promising thermal-management solution to enhance solar-powered EV charging performance under these conditions. This review employs a combined bibliometric analysis, PRISMA-guided systematic screening, and meta-analysis of 50 high-quality studies published between 2015 and 2025. Random-effects modeling, meta-regression, and cross-study thematic synthesis were employed to evaluate the thermal behavior of PCM, PV efficiency gains, techno-economic feasibility, policy interactions, and innovation ecosystem readiness. Results indicate that PCM cooling achieves an average PV temperature reduction of 24–28 °C, resulting in a 7% efficiency improvement and an 11% increase in electrical output, with low heterogeneity in electrical metrics. Techno-economic comparisons show declining global costs for PV, storage, and PCM materials, improving the financial viability of integrated solar–storage–PCM charging systems. However, adoption remains limited by high capital risk, weak policy feedback mechanisms, and fragmented innovation ecosystems across emerging markets. The analysis demonstrates that technical feasibility alone is insufficient without supportive business models and enabling regulatory frameworks. In conclusion, PCM-enhanced PV systems represent a robust thermal-management strategy with clear performance and economic benefits for solar-powered EV charging.
