Environment Overview

We are actively addressing the risks and opportunities brought by climate change. In line with TCFD recommendations, the company leverages the framework of its Corporate Sustainability Committee and Office to systematically identify climate risks and formulate response strategies, embedding climate issues into corporate governance and risk management. Furthermore, we conduct organizational carbon accounting for offices and project site offices in accordance with the ISO 14064-1 standard to facilitate the achievement of future emission reduction targets.

1. Complete Preliminary Climate Risk Assessments: Conduct preliminary climate-related risk assessments across all operational departments to identify vulnerabilities and support risk management.

2. Conduct Specialized GHG Management Training: Deliver at least 3 training sessions on climate change adaptation and greenhouse gas (GHG) management for management and staff to enhance operational awareness and technical skill sets.

3. Execute Carbon Emission Hotspot Analysis: Complete an enterprise-wide carbon footprint hotspot analysis to identify, map, and document key emission sources.

Climate Change and Adaptation

Led by the Corporate Sustainability Committee, our climate governance framework evaluates climate risks and opportunities in accordance with TCFD recommendations to formulate corresponding action plans. Through regular risk analysis and strategy updates, Dehwa systematically integrates climate risks into its overall enterprise risk management, actively addressing challenges such as extreme weather events, raw material price fluctuations, and policy shifts while capturing growth opportunities in the low-carbon building market to drive sustainable innovation.

Climate Risk and Opportunity Matrix

Note 1: Plotted based on the business characteristics of Dehwa Construction and the climate risks and opportunities it faces. The horizontal axis represents the probability of occurrence for risks and opportunities, while the vertical axis represents their potential impact on the company. Both are assessed on a scale of 1 to 5, where 1 indicates the lowest probability or impact, and 5 indicates the highest. The risk index is calculated by multiplying the probability score by the impact score. When the risk index exceeds 15, the risk is identified as high-risk, requiring prioritized management and mitigation.
Note 2: Brown indicates physical risks, green indicates transition risks, and gray indicates opportunities.
