Hanmi Science plans to gradually build an environmental management system, including establishing a greenhouse gas inventory and calculating Scope 3 emissions in the short and medium term, to achieve 100% renewable energy conversion by 2040. Through this, the company plans to advance its decision-making structure, systematically identify and analyze climate change-related risks and opportunities, set detailed mid-to-long-term reduction targets, and establish a company-wide climate change response system to build a foundation for implementing environmental management. Moving forward, the company will sequentially review the introduction of renewable energy and investment in eco-friendly facilities, continuously striving to achieve its goals of introducing renewable energy by 2030, converting 50% to renewable energy by 2035, and 100% conversion by 2040.
Hanmi Science has established a greenhouse gas (Scope 1&2) inventory management system since 2025 to systematically manage emission status. Currently, greenhouse gas emissions from the Songtan plant account for approximately 85% of total emissions. Therefore, in the short term, the company is focusing on the Songtan plant, reflecting increased operating rates, and establishing a BAU (Business As Usual) scenario and pursuing renewable energy-based energy transition. Accordingly, a carbon neutrality roadmap has been established, aiming for the introduction of renewable energy by 2030, 50% renewable energy conversion by 2035, and 100% conversion by 2040.
Furthermore, to enhance the carbon neutrality roadmap in the future, the company is considering 2023, immediately after the merger of Hanmi Science and Hanmi Healthcare, as the base year for greenhouse gas reduction. The company plans to gradually concretize its greenhouse gas reduction targets against the base year through process optimization and the introduction of eco-friendly facilities.

Hanmi Science (including Online Pharm) greenhouse gas emissions total 10,836 tCO2eq. Scope 1 emissions, from sources such as boilers and gasoline, are 4,648 tCO2eq (43%), and Scope 2 emissions from electricity are 6,189 tCO2eq (57%). In the future, by measuring Scope 3, the company plans to more comprehensively understand the overall greenhouse gas emission structure across its business and enhance its mid-to-long-term reduction strategy.

Hanmi Science is implementing greenhouse gas/energy reduction activities to reduce carbon emissions. Through reduction activities in 2025, the company expects to achieve a reduction effect of 43 tCO₂eq of greenhouse gases and 865 GJ of energy. Furthermore, in 2026, the company plans to continuously expand greenhouse gas reduction activities by introducing electricity demand forecast monitoring and replacing high-efficiency chillers.


Hanmi Science continuously monitors relevant environmental issues to systematically manage environmental impacts that may arise during production and office operations. Starting in 2025, key environmental management performance, including air and water pollutants, water usage, and waste, will be regularly reported to the Board of Directors, thereby strengthening management and oversight of environmental management. Particularly in waste management, the company consistently maintains a recycling rate of over 90% annually, continuously striving to expand resource circulation. In the future, the company plans to gradually establish an environmental management system through the formulation of an environmental policy and the introduction of an environmental management system.
Hanmi Science's Songtan plant manages air pollutants by applying low-NOx burners to boilers to comply with emission standards for air pollutants generated from boiler combustion. In 2025, the headquarters replaced its boilers with high-efficiency once-through boilers to reduce fuel consumption, and the Songtan plant enhanced its pollutant management level by repairing external sludge hoppers. Through these activities, air and water pollutants were managed at levels below 70% and 60%, respectively, of the legal permissible standards.

Approximately 95% of Hanmi Science's total water intake originates from the Songtan plant. The Songtan plant utilizes groundwater and tap water as its water sources, and to reduce water costs, it has obtained permits for groundwater development and use in accordance with the 「Groundwater Act」, ensuring the legal use of groundwater. To prevent groundwater pollution, regular water quality tests are conducted, and contaminants are removed through semi-annual water tank cleaning. Furthermore, by operating water softening facilities to pre-remove calcium and magnesium components from the water, and supplying it to manufacturing processes after a UV sterilization process, optimal water quality is maintained. Meanwhile, through collaboration with manufacturing processes, we are promoting continuous improvement activities to reduce water consumption by efficiently adjusting the number of CIP cleanings for each production item.

Hanmi Group uses reusable cups in employee lounges and cafeterias to reduce the use of disposable cups. The reusable cups are made from materials free of endocrine disruptors. Employees who use the cups return them to collection points, where they are collected and cleaned by a professional washing service from a local self-sufficiency center. In 2025, 55,430 reusable cups were used in the company cafeteria, resulting in an annual reduction of approximately 1.27 tons of greenhouse gas emissions. Furthermore, coffee grounds generated in the company cafeteria are not treated as general waste but are collected through the Songpa-gu Office's coffee grounds recycling program and provided to local livestock farms as a moisture regulator and compost. The expected greenhouse gas reduction contribution from coffee grounds recycling is 0.12 tons.


Hanmi Science conducted the 'Whole Soy Milk AGAIN' program for 'Environment Day'. Employees sampled the company's Whole Soy Milk products, received education on how to properly separate and dispose of aseptic packs, and directly experienced the washing, drying, and unfolding processes.
Approximately 100 employees participated, pledging to practice environmental protection for future generations. The campaign focused on guiding the correct disposal method for aseptic packs: ▲washing them cleanly, ▲completely removing moisture, ▲unfolding and drying the packs, and ▲disposing of them separately from general paper packs. Through this activity, Hanmi Pharmaceutical aims to raise employees' awareness of resource circulation and lay the groundwork for spreading sustainable environmental protection practices in daily life.
Hanmi Group recycles disposed IT assets to promote efficient resource circulation. In collaboration with the social enterprise 'Comwin', IT waste is recycled, and refurbished PCs are used to support IT education and initiatives for underprivileged groups.
