▪︎ Sustainable Management and ESG Certification Status

In addition to the global standard certifications ISO 9001, ISO 14001 and ISO 45001 for environmental and occupational health and safety management, KISCO has sustainability certifications applicable to each industry that we work in. We incorporate these regulations into our management practices for sustainable management.

▪︎ Environment Management Laws/Regulations and Environmental Accident Response

To respond to strengthening environmental regulations, both domestically and internationally, KISCO has established dedicated teams for each area and continuously monitors all related laws and regulations, as well as guidelines from various domestic and international government and private initiatives. KISCO has established procedures to comply with these regulations and introduced management systems to manage each item.

▪︎ Monitoring Status of Laws/Regulations

▪︎ Environment Management System

KISCO has obtained ISO 14001 certification, a global standard certification for environmental management systems, at some of its facilities and has established the integrated ‘KISCO Safety, Health, and Environment Management Policy’. This policy is deployed across all facilities. We also operate environmental monitoring systems and chemical management systems to efficiently monitor energy resources, pollutants, chemicals and other environmental-related aspects and to manage environmental risks in real-time.

▪︎ Environment Management System KISCO manages environmental impacts by adopting various systems such as monitoring environmental substances, managing chemical substances, complying with regulations and carrying out environmental impact assessments. A key tool for managing our data is our Environmental Management System (EMS). The system enables real-time measurement-based monitoring of energy resources and data through a network of environmental sensors. The system is underpinned by an integrated environmental monitoring system that includes monitors for electricity and air quality. – Real-time measurement-based monitoring of energy resources and data through a network of environmental sensors. – Integrated environmental monitoring system that includes monitors for electricity and air quality

▪︎ Chemical Substances Management System KISCO’s electronic Chemical substances Management System (eCMS) is a substance management and regulation database. It includes over 40,000 domestic and 400,000 overseas-registered chemical substances. It assists compliance with 15 environmental safety regulations including the Korean Chemical Evaluation Act, the Korean Chemicals Act, the Industrial Safety Act and similar regulations in 47 other countries. The system enables the proactive review of information related to purchase, manufacturing, handling, licensing, performance management and partnering. The system also has an integrated MSDS inventory management module.

▪︎ Environmental Impact Assessment Management – ISO 14001 The environmental team of KISCO established a process to conduct initial, regular and random environmental impact assessments according to the following procedures. Following the audits, corrective actions are initiated if any activities deviate from internal regulations.  1) Evaluation of internal and external issues and stakeholder requirements  2) Evaluation of process, environmental aspects, environmental impacts and materiality issues  3) Air, water quality, waste, noise/vibration, odor, soil contamination, resource/energy consumption audits

▪︎ Supply Chain Risk Management Policy

KISCO aims to grow together with its partners by building a sustainable supply chain based on mutual cooperation, with a strong focus on human rights and the environment. KISCO is committed to recognizing and managing supply chain transparency and continues to improve its ESG-related risk assessment system each year — not only evaluating financial and quality risks related to product supply, but also strengthening diagnostic criteria for non-financial risks such as human rights and environmental impact.

▪︎ Supplier Code of Conduct
KISCO’s Supplier Code of Conduct was established to ensure that suppliers uphold human rights and environmental values while pursuing mutual respect and co-prosperity with KISCO. The goal is for suppliers to participate in creating sustainable value through social responsibility. KISCO’s suppliers are required to comply with this code. ▸ Download Supplier Code of Conduct

▪︎ Supply Chain Risk Management Process
KISCO regularly assesses and manages risk factors within its supply chain. To ensure transparency in these evaluations, multi-layered evaluation methods are used. The company continues to advance its processes to build a more responsible supply chain.

▪︎ Environmental Impact Management

▪︎ Pollutant Emissions Management Activities

KISCO strictly complies with legal emission standards for air and water pollutants and has established even stricter internal management standards to further minimize the release of environmental pollutants.

▪︎ Reduction of air pollutant emissions

KISCO establishes internal management standards that are more stringent than the legal emission standards and continues to invest in facilities to prevent air pollution, aiming to minimize the emission of air pollutants.

▪︎ Investment in RTO and HTO Facilities

In order to prevent air pollution and to enable energy savings through the reuse of waste heat, RTO (Regenerative Thermal Oxidizer) and HTO (Heat Transfer Oxidizer) facilities have been installed. These facilities reduced hydrocarbon emissions by 99.9% and save approximately 50% of energy usage for heating by utilizing recovered waste heat.

Facility Intallation status RTO (Regenerative Thermal Oxidizer) Air pollutants and odorous substances are burned at high temperatures to decomposition. Waste heat is captured and re-used within the unit itself. ※ Installation confirmed for KIF6 plant by 2025 ※ Installation under review for KIF7 plant HTO (Hybrid Thermal Oxidizer) Air pollutants and odorous substances are burned at high temperatures to decomposition. Waste heat is captured and used in other parts of the facility. ※ KIF4, JMC: Installation completed

▪︎ Environmental Impact Target and Performance Management ▪︎  – Management of pollutant discharge after installation of KIF4 HTO ▪︎

▪︎ Steam recycling from HTO operation at KIF4
– A total of 419 MT of recycled steam in 2024 was used to produce hot water, which was reused as cleaning water.

▪︎ Reduction of Water Pollutant Emissions

To minimize the discharge of water pollutants, KISCO establishes and manages more stringent internal management standards than the legal discharge limits specific to each area where its facilities are located. Recycled water is used in many areas and some domestic facilities have their own wastewater treatment plants.

▪︎ Wastewater Treatment by Business Site
Among KISCO’s seven domestic manufacturing sites, three are equipped with in-house wastewater treatment facilities. Wastewater and waste liquid are actively reused and recycled.
