Green Products
Centering on integrated circuits (ICs), Nuvoton's core product portfolio addresses extensive applications across diverse end markets and devices, significantly optimizing global environmental management and resource utilization. With our commitment to product responsibility, Nuvoton incorporates environmental sustainability considerations at chip design stage. Through continuous technological innovation, the Company promotes the development of low-power and miniaturized chips to enhance energy efficiency and mitigate overall environmental impact. In alignment with the principles and practices of green product development, Nuvoton has established six comprehensive management stages throughout the product lifecycle, thereby embedding environmentally friendly philosophies into both product development and operational processes.
| Stage | Principles and Actions | |
|---|---|---|
| Raw material selection | Nuvoton Taiwan | Nuvoton Taiwan adheres to the principles of a circular economy by prioritizing the use of reusable process raw materials and eco-friendly chemicals. By initiating process management and resource recycling mechanisms, inorganic sludge produced during manufacturing (such as CaF2) is reused, while sulfuric acid, hydrofluoric acid, isopropanol, and organic solvents are recycled as industrial-grade raw materials. Chemical containers are cleaned and reused or transformed into recycled materials |
| Nuvoton Japan | Nuvoton Japan has formulated a green procurement policy that prioritizes the selection of environmentally sustainable substances and practices when procuring components and materials. This policy delineates explicit standards, including the "selection of materials free from harmful substances" and "prioritization of suppliers adopting processes with minimal environmental impact." | |
| Design | Nuvoton Taiwan | Nuvoton Taiwan focuses on chip miniaturization to decrease raw material usage and waste generation in end devices while simultaneously enhancing product operational efficiency and minimizing power consumption, thereby lessening environmental impact |
| Nuvoton Japan | Nuvoton Japan implements rigorous green design principles from the outset of product development. Specific strategies include a focus on "chip miniaturization" and "power reduction" to minimize raw material requirements and energy consumption during product usage. From the design phase, there is a stringent avoidance of harmful substances, ensuring full compliance with international environmental regulations, such as the RoHS Directive, REACH Regulation, and WEEE Directive. Moreover, Nuvoton Japan has established proprietary "green product" standards, setting targets for each new product to more effectively diminish environmental impact compared to antecedent generations | |
| Manufacturing | Nuvoton Taiwan | Nuvoton Taiwan prioritizes the utilization of advanced manufacturing processes for its new flagship products to achieve superior computational performance, reduced energy consumption, smaller chip dimensions & packaging, and optimized circuit board space utilization, thereby fostering a healthier and more sustainable production supply chain. Representative offerings from the Cloud Computing Business Group include the EdgeBMC for edge computing management and Embedded Controllers for commercial notebook applications, both of which are meticulously optimized for chip processing and performance |
| Nuvoton Japan | Nuvoton Japan pursues clean and efficient manufacturing processes, with internal environmental policies centered on the effective utilization of resources and the prevention of pollution. Specific initiatives include promoting resource-circular manufacturing practices through the 3Rs (Reduce, Reuse, Recycle). Through diligent management of wastewater, emissions, and solid waste, the environmental impact of manufacturing facilities is substantially reduced, while energy management is strengthened with the integration of energy-efficient equipment and process optimization to lower the carbon footprint | |
| Packaging and transportation | Nuvoton Taiwan | Nuvoton Taiwan adopts the principles of a circular economy in packaging design, enabling packaging materials to be reused multiple times throughout their lifecycle, thereby minimizing environmental impacts. Efforts are concentrated on consolidating shipments and enhancing freight capacities |
| Nuvoton Japan | Nuvoton Japan actively seeks to mitigate the environmental impact of packaging materials and logistics during product shipments. In the realm of packaging, the Company follows circular economy principles to diminish the reliance on disposable materials. In logistics, the focus on optimizing transportation efficiency aims to reduce fuel consumption and CO2 emissions significantly | |
| Usage | While semiconductor products do not emit pollutants during operation, their power consumption remains directly associated with environmental considerations. Consequently, Nuvoton is committed to offering "energy-efficient products," seamlessly integrating eco-friendly attributes into product specifications | |
| Final disposal | The Company adopts a proactive stance against the use of harmful substances, incorporating considerations for safe and convenient disposal and recycling from the design phase onward. Furthermore, Nuvoton adheres to applicable electronic waste regulations and international standards, such as the WEEE Directive, consistently managing electronic waste in a responsible and sustainable manner | |
Product Carbon Footprint
Considering the environmental impact associated with products throughout their entire lifecycle, Nuvoton integrates carbon footprint management into its sustainable product strategy. Through systematic inventory and energy and resource consumption analysis during the design, manufacturing, and utilization phases, Nuvoton is committed to continuously optimizing product designs to mitigate environmental impact. From the inception of product development, the principles of green design are incorporated, encompassing careful selection of raw materials, stringent control of emissions during manufacturing processes, and the advancement of energy-efficient products. This approach facilitates the progressive reduction of energy consumption and related emissions during both the production and usage phases, thereby advocating for carbon reduction at the source.
In 2024, Nuvoton Taiwan successfully completed the carbon footprint audit for its wafer products in accordance with the ISO 14067:2018 standard, subsequently obtaining third-party verification. This initiative enables the Company to identify critical stages in the product lifecycle that possess potential for carbon reduction. Since 2025, Nuvoton Japan has performed a comprehensive carbon footprint audit for its product offerings, systematically managing carbonemissions throughout the entire lifecycle of major products, with a target to achieve ISO 14067:2018 third-party certification by 2026.
Nuvoton Japan has established an internal environmental sustainability task force, collaborating closely with the Taiwan headquarters to develop a robust product carbon footprint auditing framework. This framework employs a methodology of systematically gathering emissions data from suppliers related to each phase of wafer processing and packaging, enabling the quantification of differences in carbon footprints between new and legacy product generations. Internal audits follow the guidelines set forth in ISO 14067 and integrate the life cycle assessment (LCA) methodologies outlined in ISO 14040 and ISO 14044.
By 2026, Nuvoton will complete a comprehensive assessment of energy consumption and greenhouse gas emissions associated with our primary product, semiconductor integrated circuits (ICs) . This evaluation spans from raw material procurement and manufacturing to packaging and logistics, establishing a solid foundation for pursuing ISO 14067 certification. Additionally, the Company will extend educational training on carbon footprint auditing to relevant departments and establish a cohesive communication framework with Nuvoton Taiwan to facilitate the development of a comprehensive emission data management system.
