Environmental | IF-EN-160a.1 | Number of incidents of non- | 0 cases | 0 cases |
IF-EN-160a.2 | Discussion of processes to | Remediation and action plans are developed for potential environmental risk factors identified during environmental impact assessments. These are utilized as the basis for formulating and implementing construction plans. In addition, the environmental impacts that project activities may have across various areas—including air, soil, water quality, and biodiversity—are comprehensively identified, while mitigation measures are established to minimize any negative impacts. Emission standards are strictly enforced for each environmental factor—such as waste, water quality, and air pollutants—while inspection processes and monitoring systems are operated to ensure transparent management. Checklists have been developed covering key items—including air quality, waste, noise and vibration, and water quality—for the entire project lifecycle, from permits and operations to the implementation of prevention and control measures. Internal inspections are conducted based on these checklists. In addition, a “Standard Model for Site Environmental Issue-Centered Management” has been developed and is in use to quickly identify environmental issues at each site. Unscheduled inspections are also conducted at all sites based on six major non-conformity items in key processes, thereby ensuring compliance with environmental regulations. | ||

IF-EN-410a.2 | Discussion of process to | SK ecoplant and SK ecoengineering are implementing measures to optimize resource use and reduce environmental impact at construction sites and during the design phase. During the design phase, pre-construction technology is utilized to review risk factors and process plans in advance, thereby reducing unnecessary waste of resources and contributing to improved project quality and safety. To reduce energy and water consumption, passive design elements—such as improved insulation, high-efficiency windows, and designs that maximize natural lighting and ventilation—are employed to minimize heating and cooling energy use, while water consumption is managed through rainwater reuse systems. In addition, water resource recycling measures—such as rainwater storage, wastewater reuse, and the utilization of groundwater runoff—tailored to site-specific conditions are implemented. Stored rainwater and reused water are utilized for non-potable purposes such as landscaping, cleaning, and sprinkling, while groundwater runoff is used to mitigate heat waves and reduce airborne dust, thereby reducing the site’s water consumption burden. In terms of materials and waste management, the use of recyclable or locally sourced materials is evaluated based on site conditions. A system of separate collection, reuse, and recycling is implemented to reduce waste generated during construction and operation. | ||

IF-EN-510a.3 | Description of policies and (1) Bribery and corruption (2) Anti-competitive behavior in the project bidding | The Code of Ethics applies to all domestic and international branches and subsidiaries, with compliance being encouraged to all stakeholders with whom the company has business relationships. Ethics training is carried out and employees sign compliance pledges, while violations of regulations and laws are monitored through periodic audits and anti-corruption risk assessments. Based on SK Group’s “Anti-Corruption Risk Management System and Capability” indicators, anti-corruption risks are identified and evaluated company-wide. Improvement measures are implemented, and regular reports are made to the Board of Directors. The Fair Trade Compliance Program (CP), overseen by a Compliance Officer and Chief Compliance Officer appointed by a resolution of the Board of Directors, was introduced in 2008. The contract execution process is monitored to prevent legal violations; this is conducted through pre-inspection systems and internal monitoring mechanisms, such as prior reporting of industry meetings to prevent bid-rigging, preventing unfair subcontracting clauses through prior review of site instructions, operating the Technical Data Management System (TDMS), and preventing technology theft. Through written and on-site inspections, monthly checks are carried out on all domestic projects for violations of the Fair Transactions in Subcontracting Act and Framework Act on the Construction Industry. Corrective measures and disciplinary procedures are implemented based on the results. | ||
