Climate Change Response Strategy

As physical and transition risks associated with climate change increase, companies that fail to establish appropriate climate change response strategies are increasingly likely to suffer financial losses.

Overview of Scenario Analysis

ST Pharm continuously monitors the global environment and deeply understands the impact of climate change on corporate sustainability and management activities. For this reason, we conducted a climate change scenario analysis to systematically evaluate the risks and opportunities posed by climate change to our business operations and proactively manage them. In the process of scenario analysis, we secured the validity of the analysis through interviews with external experts and a climate change scenario analysis workshop, and applied various future climate change scenarios to assess the potential impact on our operations and establish response strategies.

Climate Risk Analysis Results

ST Pharm conducted scenario-based assessments of the 25 selected climate change risks, analyzed the risk patterns under the 1.5°C and 4.0°C scenarios, and derived changes by period (short-term (~2030), medium-term (~2040), and long-term (~2050)) and the impact on business operations. In the 1.5°C scenario, climate change risk patterns revealed a significant surge in policy and regulatory risks, as well as an ongoing increase in transition risks. In the 4.0°C scenario, physical climate risks were increased sharply, and market and supply chain risks continued to grow.

Climate Risk Management Framework

ST Pharm has set short-, medium-, and long-term time horizons for responding to climate change, and conducted scenario analyses accordingly. In detail, we have systematically analyzed climate change scenarios up to 2050, taking into account the achievement of our net zero carbon emissions target. Through this analysis, we assess the impact of climate change on our business operations and develop response strategies for sustainable growth. The analysis results will serve as an important basis for setting GHG reduction targets and establishing implementation plans, and will contribute to minimizing climate change risks in the long term.

Climate-Related Targets

Establishing Science-Based GHG Reduction Targets

ST Pharm supports the Science Based Targets initiative's (SBTi) target of reaching net-zero by 2050, and as part of this, has made a commitment to SBTi Services to set near-term targets in February 2025. In accordance with the SBTi guidance, we have set a near-term reduction target (SBT) aimed at achieving reductions by 2035, and will seek verification and approval of the target in the future. Our GHG reduction target includes Scope 1 (direct emissions), Scope 2 (indirect emissions), as well as emissions from categories 1, 3, and 5, which account for approximately 95% of our total Scope 3 (other indirect emissions) emissions.
We aim to reduce our Scope 1 & 2 emissions by 63% (based on 1.5° C) and our Scope 3 emissions by 37.5% (based on WBC2) by 2035 compared to the baseline year. Going forward, ST Pharm plans to establish specific Scope 1, 2 and 3 reduction strategies based on the SBTs, which will drive company-wide implementation activities to achieve net-zero.

Minimizing Environmental Impact

ST Pharm employs a systematic governance structure to respond to climate change and strengthen environmental management, thereby promoting an effective climate change response. The Board of Directors serves as the highest decision-making body overseeing climate-related risks and opportunities, regularly reviewing climate change response and environmental management goals and achievements.

Compliance with Environmental Regulations

ST Pharm operates domestic production sites, and obtains permits from the competent authorities for the initial installation and modification of facilities in accordance with domestic laws, regularly reporting on the management status to the authorities. In addition, we monitor the status of revisions to relevant laws on a monthly basis and record the results based on the EHS Goal & Performance Management SOP. Based on this, we establish a strategy for responding to safety, health, and environmental needs, including eco-friendly investments.

Water Resources Management

To identify and manage the water-related impacts of our business operations, ST Pharm conducted a WRI Aqueduct water stress analysis and a review of OECD academic literature.1) Through this research, we identified Gyeonggi-do, South Korea, where our manufacturing sites in Sihwa and Banwol Campus are located, as a low-to-medium water stress region. Reflecting this regional characteristic, we have established strategies to effectively treat the wastewater generated from our operations, and operate a thorough water discharge system to minimize the water-related impacts of our business.

Wastewater Management

The wastewater generated by our company goes through primary physical and chemical treatment, secondary biological treatment, and tertiary membrane filter treatment to remove pollutants at our in-house wastewater treatment plant before being transported to the sewage plant for end treatment. The wastewater is then finally discharged into the West Sea, with pollutants regularly analyzed and measured before discharge to ensure compliance with legal standards. Sludge waste generated during the
biological treatment process is collected by a specialized company and recycled as fertilizer to minimize its environmental impact.

²⁾ Concentrated water generated from the production of purified water is fully recovered and reused as industrial water.
³⁾ Water withdrawal intensity = Total water consumption / Consolidated sales

Pollutant Monitoring and Quality Control

In addition to legal standards, we have established our own management standards to strengthen the monitoring of pollutants in wastewater discharges. To this end, we measure the TOC and pH level of raw water, wastewater, and discharged water on a daily basis, and send samples once a month to an external specialized company for analysis to continuously check the water quality.

Water Pollution Management Goal

ST Pharm has set a water pollution management goal for 2025 of maintaining total nitrogen (TN) emissions from our wastewater treatment plants at less than 80% of the legal limit. To achieve this, we have introduced total nitrogen measuring devices to accurately monitor the nitrogen concentration of wastewater entering and discharged from wastewater treatment plants. At the Sihwa Campus, we further improved wastewater treatment efficiency by replacing and installing anoxic tank agitators2) to complement the total nitrogen removal device. Going forward, ST Pharm will continue to strengthen our eco-friendly operations by proactively managing water quality and reducing wastewater.

Waste Management

ST Pharm strives to reduce waste generation by continuously improving the entire process of product production, use, and disposal. Waste generated at our business sites is strictly managed according to our Waste Management SOP, and we comply with legal standards and maintain records throughout the entire process of storage, transportation, and disposal. In addition, we actively identify recyclable waste to reduce our disposal costs and systematically manage our circular economy performance by expanding recycling. At our manufacturing sites, we categorize waste by type, precisely calculate the amount of waste generated and discharged, and promptly record this information in “Allbaro,” the national waste management system, for transparent management.

Reducing Waste Treatment Costs

ST Pharm is reducing waste treatment costs by changing waste treatment methods, recycling empty drums, and implementing in-house treatment.

Expanding the Recycling of Waste

Each year, ST Pharm sets waste management targets and strives to achieve them in order to manage resource circulation performance in our business sites in accordance with the Framework Act on Resources Circulation. Resource circulation performance management is operated in line with the national mid- to long-term circular economy goals to suppress waste generation and promote recycling. Accordingly, ST Pharm systematically manages the material flow of waste from generation to its final disposal, and manages the implementation performance every year with the goal of growing the amount of recycling (increasing the circular utilization rate) and minimizing the amount of final disposal (reducing the final disposal rate).

ST Pharm clearly manages the hazardous properties of all chemicals by affixing GHS labels to all chemical containers to ensure that environmental pollution and safety accidents during the handling and transportation of chemicals are prevented. In addition, workers handling hazardous chemicals are required to complete mandatory training to ensure that they are familiar with safe handling methods. Furthermore, large quantities of solvents are transported via pipes, and drum-type solvents are transported using forklifts to minimize direct contact with workers. Areas in which hazardous chemicals are handled are equipped with gas detectors, fire extinguishers, and emergency showers. Loading and unloading areas have spill prevention measures in place to enable a swift response in the event of an accident.

Storage of Chemical Substances

ST Pharm operates outdoor and indoor storage facilities for the safe storage of chemicals, and applies a robust management system. In outdoor storage, dikes and inter-lock systems are built to prevent spills and overpressure accidents, and gas detectors, lightning rods, and fire extinguishing facilities are installed to prepare for fire and explosion accidents. In addition, hazardous chemicals are transported by licensed specialists to ensure their safe handling. Indoor storage is managed with spill prevention
trenches and a hazardous substance classification system, and gas and leak detectors and fire extinguishing equipment are installed to ensure an immediate response in the event of an accident. In addition, we apply fall prevention devices and GHS labels to enhance safety in loading and storage.

MSDS Management

ST Pharm systematically manages safety and handling information for all chemical substances, and ensures company-wide accessibility to promote their safe use. We manage Material Safety Data Sheets (MSDS) for raw materials, substances manufactured in-house, and CMO products from manufacturers, laboratories, and clients, and post MSDSs to our in-house cloud system for real-time access.

Accordingly, we systematically implement a legal soil contamination management process in accordance with the relevant laws and regulations, and minimize environmental risks to soil through a prevention oriented management approach that goes beyond the legal requirements. We regularly inspect our business sites for soil contamination, and the latest inspection confirmed the safety of the soil environment. We have also completed a comprehensive set of protective measures to prevent spread and respond quickly in the event of a contamination.

• Installing dikes: stop the spread of leaks outside the storage facility
• Installing a gas leak detector: quickly detect soil contaminant leaks and confirm leakage
• Building storage facilities with reinforced concrete structure: ensure structural stability

Efforts to Preserve Biodiversity

ST Pharm recognizes biodiversity as an important element of environmental management, and considers it in its efforts to build a sustainable management system. For this reason, we are establishing a biodiversity management strategy in stages based on the LEAP (Locate, Evaluate, Assess, Prepare) process. LEAP is an international approach that was designed to help organizations assess their relationship with nature and develop effective management and response plans. We are currently in the early stages of the process, with our first priority being to understand the state of biodiversity and ecosystems in the regions where our major operations are located. By doing this, we will gain an understanding of the ecological characteristics and importance of biodiversity in these areas, and build a data foundation that will enable more precise assessments.
ST Pharm will move forward to assess the dependence and impact of our business activities on natural capital. To this end, we plan to comprehensively analyze the land use status of the areas in which our business sites and supply chains are located, the characteristics of nearby ecosystems, and the habitats of key species. We will also set targets for reducing our environmental impact and develop specific corporate strategies for protecting biodiversity.

Safety and Health Risk Management

ST Pharm applies a systematic Process Safety Management (PSM) system designed to prevent serious safety accidents that may occur in the process of handling or manufacturing hazardous substances. Based on this system, we systematically manage our business sites through risk assessment, the preparation of Standard Operating Procedures (SOPs) and operation manuals, safety management of facilities and equipment, training, and emergency response plans.

Risk Assessment

ST Pharm conducts regular and ad-hoc risk assessments to identify, correct, and prevent safety and health risks across our business. Regular risk assessments are conducted annually to identify, address, and manage hazards, risks, and potential accidents across the business, in the areas of facilities, processes, and operations, with the goal of eliminating accidents and ensuring the safety of workers. Ad-hoc risk assessments are conducted for operations where additional hazards and risks may arise due to an introduction or change of equipment, raw materials, work methods, etc. Through the risk assessment, potential risks in detailed processes are identified through Checklist, HAZOP and JSA techniques, and improvement measures are implemented for the identified risks. The results of risk assessment and the status of corrective measures are shared with all employees, and the effectiveness of corrective measures is checked through a subsequent risk assessment after improvement. In addition, the Chief Safety Officer reviews the results of hazard and risk factor identification and improvement activities twice a year, reports the results to the BOD, and receives approval for the plan.

Workplace Inspection

To prevent safety accidents in its facilities and workplaces, ST Pharm regularly undergoes both internal selfinspections and external inspections performed by specialized organizations. Depending on the purpose and target of the inspection, various inspectors check firefighting facilities and working environments to ensure workplace safety. All inspection findings are documented, and any problems discovered are subject to corrective action procedures. In addition, we meet the standards of safety and health management during the audit by various global clients, advancing the level of safety and health management.

Emergency Response System

ST Pharm has an emergency control organization at each business site to respond quickly to emergencies and minimize loss of human and physical resources.
