To gain a more comprehensive understanding of ESG development trends, it is recommended to analyze TESG score changes together with upgrade and downgrade patterns, thereby improving the accuracy and insightfulness of interpretation.<\/p>\n\n\n\n<p><strong>Figure 1.

First, in terms of greenhouse gas emissions, industries with higher environmental impact, such as <strong>Extractives &amp; Minerals Processing<\/strong> <strong>and Transportation<\/strong>, show significantly higher median carbon emissions per million in revenue than other sectors. Although these figures have been declining, the pace of improvement remains constrained by industry-specific production processes.By contrast, sectors such as <strong>Financials, Technology &amp; Communications, and Services<\/strong> generally have lower carbon intensity, as their business models rely less on physical assets, as shown in Figure 3.<\/p>\n\n\n\n<p><strong>Figure 3.

According to SASB industry classification, <strong>Financials, Health Care, and Technology &amp; Communications<\/strong> all identify data security as a highly material issue.<\/p>\n\n\n\n<p>As shown in Figure 4, the overall CISO appointment rate increased significantly from 2023 to 2026, with the most notable improvement in the financial sector. However, the appointment rates in <strong>Technology &amp; Communications and Health Care<\/strong> remain relatively low, suggesting that industries highly dependent on data and privacy protection still have room to strengthen their cybersecurity governance mechanisms.<\/p>\n\n\n\n<p><strong>Figure 4.

Unlike CISOs, whose appointment is subject to explicit regulatory requirements, CSO appointments are mainly driven by the FSC\u2019s <strong><em><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-orange-color\">Sustainable Development Action Plans for TWSE- and TPEx-Listed Companies<\/mark><\/em><\/strong>, reflecting companies\u2019 growing emphasis on sustainability.<\/p>\n\n\n\n<p>As shown in Figure 5, the overall appointment rate has reached a relatively high level, suggesting that most industries have moved beyond the initial stage of governance framework establishment and entered a phase of deeper governance integration. In sectors such as <strong>Consumer Goods, Construction, and Resource Transformation<\/strong>, where climate, resource, and supply chain issues have significant financial implications, the focus is shifting toward linking decarbonization and resource efficiency with operating performance and capital allocation.<\/p>\n\n\n\n<p>By contrast, growth in the <strong>Services and Financials sectors<\/strong> has slowed, indicating that sustainability functions are increasingly embedded into risk management, investment and financing, and human resources systems. Going forward, the key to competitiveness lies not only in whether a company appoints a CSO, but also in whether the role can drive cross-functional integration, embed material ESG issues into decision-making, and translate them into measurable performance and long-term value creation.<\/p>\n\n\n\n<p><strong>Figure 5.
