Climate Change Response Journey

Climate Change Response Governance

SK ecoplant is continuously enhancing its internal management systems to proactively address climate change risks and opportunities and to implement a company-wide business transformation strategy aimed at achieving net-zero. At the operational level, the ESG Strategy and Management Team leads the formulation and implementation of the net-zero strategy while continuously monitoring climate change-related risks and regulatory trends. Through the ESG Regulatory Response Council, established in 2024, the company manages carbon emission reduction metrics and strengthens its capacity to respond to ESG regulations.

Within the “Net Zero Implementation Module,” each business division discusses practical measures for reducing greenhouse gas emissions and develops implementation strategies. Having been designated as a company subject to the Greenhouse Gas and Energy Target Management System in both 2024 and 2025, SK ecoplant conducted training on system compliance at key sites, such as the Yongin Semiconductor Cluster. The company also carefully reviewed the organizational boundaries of each business unit to reduce greenhouse gas emissions and projected emissions that reflect the specific conditions of each business. Furthermore, net-zero roadmap scenarios are continually being evaluated to reflect restructuring of the business portfolio—including subsidiaries—as well as current business conditions.

Through the “Disclosure Compliance Module,” SK ecoplant proactively prepares for mandatory ESG disclosure on a consolidated basis while reviewing and addressing the demands of internal and external stakeholders. In 2025, consolidated disclosure standards, data metrics, and guidelines for mandatory ESG disclosure were established and refined. An IT system for ESG data management was introduced, while procedures were added to designate personnel responsible for each data metric and implement approval processes for data reliability. Going forward, the company plans to expand the scope of data collection and IT system implementation to include subsidiaries. SK ecoplant further aims to identify key risks and opportunities arising from the impacts of climate change on a consolidated basis— including subsidiaries—while also progressively conducting scenario-based impact analyses and developing response strategies.

The Board of Directors and Strategy and ESG Committee conduct annual reviews of the company’s climate change response strategy and the progress toward achieving greenhouse gas reduction targets. Decisions on major investment proposals are made only after comprehensive risk assessments by the Investment Deliberation Committee and the Bid Deliberation Committee. Management receives regular reports on greenhouse gas reduction performance through the ESG Council and, based on this information, reviews the company’s business structure and management activities with a focus on climate change response.

Organizational Chart for Climate Change Response

Strengthening the Roles of the Board of Directors and Strategy and ESG Committee

SK ecoplant’s Strategy and ESG Committee is the highest decision-making body responsible for formulating climate change response strategies and managing and overseeing their implementation. Established in 2021 under the Board of Directors, the committee has spearheaded discussions on climate change response and has formulated ESG strategies and business plans while monitoring their performance. Furthermore, to enhance the Board’s expertise, the company appoints individuals with specialized knowledge and practical experience in various fields—including business strategy, ESG, and global capacities—from the very beginning of the Board selection process.

In particular, as climate change response has become a core element of business strategy, expertise in this area is now a key criterion in the appointment of directors. The Strategy and ESG Committee meets at least four times a year and performs key functions related to climate change strategy, such as deliberating on net-zero implementation strategies and major investment proposals related to climate change response.

The Strategy and ESG Committee reviews major non-financial risks and opportunities across the entire company, encompassing SK ecoplant and its subsidiaries, ensuring that climate change issues are fully incorporated into the investment and business planning processes. In particular, for significant investment proposals above a certain threshold, the ESG organization’s written opinions on climate change risks and opportunities are reported to the Board of Directors as needed. Matters related to environmental management and climate change response performance are regularly reported to the Board of Directors and Strategy and ESG Committee at least once a year. In 2025, the Strategy and ESG Committee convened to discuss major management issues.

Agendas for Reporting and Resolution by the Board of Directors and Strategy and ESG Committee

Climate Change Response Training for Independent Directors

SK ecoplant conducts regular training to strengthen the climate change response capabilities of its independent directors. The Board of Directors’ expertise and decision-making capabilities are enhanced through trend reports on key management issues and tailored training. In 2025, the company monitored trends in strategic shifts among global energy companies and, based on this analysis, assessed potential strategic synergies with its business portfolio.

Executive KPI Linkage

To ensure effective climate change response, SK ecoplant has designed and implemented ESG key performance indicators (KPIs) company-wide in a phased manner, from the CEO down to business units and teams. In 2022, the CEO’s KPIs included performance metrics for achieving annual greenhouse gas reduction targets, and starting in 2024, the weighting of non-financial performance—such as carbon emissions reductions and evaluation results for key climate change indicators—was increased to 10%. The decision to grant incentives based on these metrics is made following deliberation by the Board of Directors. Each business division establishes KPIs linked to company-wide greenhouse gas reduction targets and incorporates them into their compensation systems. The company is also implementing climate change response metrics tailored to its business characteristics, such as carbon emissions reduction, Scope 3 inventory development and reduction, and supply chain management. At the team level, detailed KPIs linked to company-wide reduction targets are set to promote the systematic development and execution of work plans. Through a KPI system that is progressively linked from the CEO down to each team, SK ecoplant is enhancing its ability to implement climate change responses aimed at achieving net-zero.

Supporting Subsidiaries’ Climate Change Response

As ESG management requirements for subsidiaries intensify, SK ecoplant is working to advance ESG management at its subsidiaries through the ESG Regulatory Response Council. First, the ESG performance of each subsidiary is assessed, taking into account its size and business characteristics. Based on these results, customized consulting and improvement recommendations are provided for each subsidiary to ensure that ESG management activities are effectively embedded.

In terms of climate change response, SK ecoplant goes beyond simply managing subsidiaries’ Scope 1 and 2 emissions; it also calculates Scope 3 emissions, which include emissions from major subsidiaries. Furthermore, by identifying key reduction measures for each subsidiary and providing expert consulting to enhance their feasibility, the company continues to offer practical support so that each subsidiary can independently develop and implement its own greenhouse gas reduction strategies.

In the medium to long term, SK ecoplant plans to provide phased support to help each subsidiary develop the capacity to respond independently to changes in the external environment. Through this, the company aims not only to proactively address clients’ climate change requirements and prepare for mandatory greenhouse gas disclosure obligations, but also to support subsidiaries in establishing and implementing their own reduction targets. To ensure resilience against transition risks, a net-zero target implementation framework that includes subsidiaries is also being established. By implementing a process to rapidly detect and proactively respond to climate change risks, losses caused by such risks are being minimized, while a transition to a sustainable business structure is being realized.

Physical Risk Scenario Analysis

Physical risks caused by climate change—such as extreme temperatures, sea-level rise, and flooding—are gradually affecting corporate assets and operational stability in various ways. Furthermore, given the uncertainty of climate scenarios and the nature of the construction industry—where projects typically conclude within 3 to 5 years—mid-to-long-term loss estimates based on fixed assets have inherent structural limitations.

Accordingly, SK ecoplant selected seven regions (at the city level)—including Ulsan, Yongin, and Icheon—as subjects of analysis, assuming that future construction sites will be located in areas similar to current ones. Factors such as connection to current major projects, scale and duration of construction sites, and the sites’ location were also taken into account. Additionally, to analyze the financial impact of physical risks on business operations and assets, the company utilized the Korea Meteorological Administration’s Climate Information Portal and the S&P Global Climanomics platform.

Selection of Climate Scenarios

For the physical risk analysis, SK ecoplant applied the SSP (Shared Socioeconomic Pathways) scenarios based on the IPCC (Intergovernmental Panel on Climate Change) 6th Assessment Report, and analyzed comprehensive risks under low-carbon, medium-emission, and high-carbon emission scenarios.

Analysis Results: ① Risk Identification

Taking into account industry characteristics and project impacts, SK ecoplant identified the number of heatwave days, precipitation, torrential rain, average temperature, and sea-level rise as key physical risk factors. Subsequently, the company analyzed and evaluated trends in related indicators for 2030 and 2050 compared to the base year of 2021. For the scenario analysis, the Korea Meteorological Administration’s National Standard Climate Change Scenarios were utilized to adapt the IPCC’s SSP scenarios to Korea.

Analysis Result ② Financial Impact

SK ecoplant analyzed financial impact based on electricity unit prices and electricity consumption (projected electricity consumption in 2050 compared to the base year) in relation to the increase in the number of heatwave days and average temperatures, which have the most direct impact on construction sites. As a result, electricity consumption (kWh) due to an increase in the number of heatwave days is projected to rise from 12.8% (SSP 1–2.6) to 21.8% (SSP 5-8.5) compared to the base year, while consumption resulting from rising average temperatures is also projected to increase from 4.5% (SSP 1-2.6) to 9.8% (SSP 5-8.5).

Furthermore, an analysis using S&P Global’s ClimanomicsⓇ Hazard Modeling indicated that the impact of disaster types such as extreme temperatures, sea-level rise, droughts, river flooding, torrential rains, typhoons, water stress, and wildfires would be minimal, with an annual asset value loss rate of less than 1% (LOW level). However, as the asset loss rate due to abnormal temperatures is showing a gradual upward trend, the company is operating a continuous monitoring and management system to prevent risks to employee safety and health, as well as declines in productivity.

Response Activities

Through the Disclosure Compliance Module of the ESG Regulatory Response Council, SK ecoplant identifies and assesses key risks and opportunities for the company and its subsidiaries arising from the impacts of climate change. After deriving risks and opportunities by business unit and subsidiary—taking into account internal and external policies, market conditions, and the magnitude and frequency of financial impacts—common and key control items are identified and managed In addition, scenario-based impacts for each item are analyzed, while criteria is established for calculating financial impacts. After setting the direction of response strategies and mid- to long-term goals, short-term goals, performance targets for the current year, and detailed activities for strategy execution based on target levels and achievement timelines are established and implemented. Going forward, SK ecoplant plans to utilize climate materiality assessment to advance calculation criteria and processes for determining the magnitude, scope, and probability of business and financial impacts triggered by key climate change risks and opportunities. Furthermore, the number of subject subsidiaries will be expanded according to the consolidated disclosure scope.

Assessment of Key Risks and Opportunities

SK ecoplant analyzed the risks and opportunities arising from climate change, assessed the impact and likelihood of each factor, and identified material risks and opportunities. Analysis results, as well as response measures, are transparently disclosed. The potential impact of risk factors on financial performance is assessed, with mitigation measures and response strategies being implemented to ensure resilience. Strategies aligned with the business model, market trends, enhanced competitiveness, and stakeholder needs are developed to transform opportunity factors into new business opportunities. By continuously monitoring and strategically managing these risks and opportunities, SK ecoplant is further strengthening its proactive response capacity for climate change.

Risk Management

Climate Change Risk Management

SK ecoplant operates a systematic implementation process to integrate key risks and opportunities arising from climate change into its company-wide risk management framework. The company establishes a pool of climate-related risks and opportunities by comprehensively analyzing the characteristics of its business value chain—including subsidiaries—as well as external regulations, market changes, industry trends, and literature reviews. The short-, medium-, and long-term likelihood of each factor and its potential impact on business is then analyzed, through interviews with relevant internal departments and external experts. Key risks and opportunities are identified based on these findings.

Based on scenario analysis, the identified key risks and opportunities are translated into concrete response strategies that align with SK ecoplant’s ESG strategy, mid- to long-term growth direction, and stakeholder expectations, before being implemented. During the strategy implementation process, key performance indicators are established, and performance against targets is periodically reviewed to strengthen the company’s ability to respond to climate change issues. SK ecoplant is currently optimizing its emissions reduction portfolio based on a cost-benefit analysis that takes into account the costs and effectiveness of each response strategy. Going forward, the company plans to expand quantitative analysis to focus on factors with high probability of occurrence and significant financial impact, and to transparently disclose the results to the public.

The response strategies and implementation results derived through the risk monitoring process are reported to the Board of Directors, Strategy and ESG Committee, as well as the CEO, and are reflected in the formulation of company-wide management strategies. Furthermore, to pro-actively prepare for the mandatory disclosure requirements on a consolidated basis, SK ecoplant operates a Disclosure Compliance Module under the ESG Regulatory Response Council. Starting with the enhancement of subsidiaries’ ESG data management systems, the company is also strengthening their climate risk response capabilities.

Climate Change Risk Management Process

Investment Decision-Making

SK ecoplant comprehensively considers the risks and opportunities associated with climate change when reviewing investment proposals. These are incorporated as key factors in investment feasibility assessments. Starting in 2024, to ensure more objective and transparent decision-making, the company has introduced a voting system for its review committee and bases decisions for eligible projects on identified risks and verified information. Furthermore, an independent and fair investment review system has been established by separating the preliminary review and final decision-making bodies while creating a new oversight body composed of experts in various fields, including technology, ESG, and marketing. This body conducts comprehensive reviews of investment proposals and raises dissenting opinions; during the decision-making process, the final vote is cast after comprehensively considering both the results of the preliminary review and these dissenting opinions. In particular, when making new investments, SK ecoplant incorporate various factors—such as changes in greenhouse gas emissions and policy shifts—into feasibility assessments to inform strategic decision-making.

Furthermore, SK ecoplant has proactively introduced an internal carbon pricing system to quantitatively reflect the financial impacts of climate change. Through this system, the company aims to more realistically account for regulatory compliance costs, transition costs, and projected operating costs, thereby effectively managing greenhouse gas emission risks at the investment review stage. The internal carbon price was set by referencing the annual carbon price (as of 2022) from the GCAM 5.3+ model—one of the Net Zero 2050 scenarios developed by the Network for Greening the Financial System (NGFS)—to align with the 2040 net-zero target. SK ecoplant is currently in the process of gradually adjusting this price to reflect portfolio rebalancing and actual operating conditions. This framework is being adjusted to enable more substantive and consistent decision-making, and continuous reviews and refinements are planned in response to future market conditions as well as policy changes.

Investment Decision-Making Process

Greenwashing Pre-Review System

SK ecoplant operates a company-wide pre-review system for environmental claims in advertising, based on Article 3, Paragraph 1 of the Act on Fair Labeling and Advertising and Article 16-10, Paragraph 1 of the Environmental Technology and Industry Support Act. The review scope includes not only advertisements but also press releases, ESG disclosures, and all externally published materials that may influence stakeholders. The department drafting the material conducts an initial self-review based on company-wide guidelines and a self-assessment checklist. Subsequently, the Compliance and Legal teams conduct a professional pre-review and provide revision feedback. Through this process, SK ecoplant enhances the accuracy and credibility of its external communications and proactively prevents legal and reputational risks associated with environmental claims.
