Samsung Semiconductor is charting a course toward Net Zero for Scope 1 and 2 by 2050, guided by our long-term strategic roadmap.
We are driving this transition through a dual approach: reducing direct emissions via advanced process and facility enhancements, and lowering indirect emissions by maximizing energy efficiency and expanding our renewable energy footprint.
Our vision extends beyond our own walls. By advancing our emission tracking systems and empowering our partners across the supply chain, we are systematically managing carbon footprints across the entire value chain—including Scope 3—to help every stage of our product's lifecycle contribute to reducing emissions across the value chain.

To reduce fuel consumption, Samsung Semiconductor is implementing a comprehensive strategy focused on process operation optimization, the introduction of non-fuel facilities, and the operation of advanced waste heat recovery systems. These recovery systems capture heat that would otherwise be discarded and repurpose it for outdoor air heating and hot water production, significantly reducing the usage of LNG.
As a result of these initiatives, the waste heat utilization rate at the Giheung, Hwaseong, and Pyeongtaek sites reached 55% in 2025. Samsung Semiconductor plans to expand these systems to existing production lines, further enhancing thermal energy efficiency across all business sites.

Samsung Semiconductor prioritizes the management of suppliers with high emission proportions based on Product Carbon Footprint (PCF) analysis. To ensure accuracy, we calculate and verify emissions through a specialized system integrated with procurement data.
In collaboration with key suppliers, Samsung Semiconductor establishes greenhouse gas reduction targets and regularly monitors their implementation status. As a result, 82% of key suppliers had established reduction targets as of 2025. Furthermore, we provide practical support for tangible reduction activities, such as improving energy efficiency and transitioning to cleaner fuels, through greenhouse gas management training, technical exchange sessions, one-on-one on-site consulting, and the utilization of an ESG fund.

Samsung Semiconductor calculates and manages carbon emissions on a per-product basis, covering the entire lifecycle from raw material extraction to product shipment. Utilizing an automated Product Carbon Footprint (PCF) system based on international standards and Life Cycle Assessment (LCA) processes, we collect detailed activity data, including raw material input, energy consumption, and waste generation. By applying emission factors from the Life Cycle Inventory (LCI) database, we precisely determine the emissions generated throughout the product manufacturing process.
Based on these calculation results, we identify emissions by business site and process to establish targeted reduction measures centered on major emission sources. We ensure the reliability of our findings through regular data updates and rigorous third-party verification. Moving forward, we plan to continuously improve the accuracy of our PCF by supporting suppliers in directly calculating the footprints of raw materials supplied to Samsung Semiconductor and increasing the proportion of primary data integrated into our system.
