Greenhouse Gas (GHG) Emissions
As an IC design company, Etron is not a high-energy-consuming enterprise. However, we regard the reduction of GHG emissions as a collective corporate responsibility and a key sustainability goal.
The Company conducts voluntary inventories following the ISO 14064-1 GHG inventory framework to track current emission status and trends, enabling early planning of response measures. Simultaneously, we are actively formulating GHG reduction strategies and concrete action plans, while participating in the CDP (Carbon Disclosure Project) to enhance information transparency and strengthen corporate sustainability competitiveness within the international supply chain.

GHG Inventory Certificate (ISO 14064-1)
In response to global climate change risks and the international trend toward a net-zero transition, Etron continues to integrate greenhouse gas (GHG) reduction into its core corporate sustainability strategy. Following national net-zero policies and global carbon reduction trends, the Company is progressively advancing low-carbon transformation and energy management initiatives. Through GHG inventories, energy usage management, and energy-saving measures, we continuously monitor carbon emissions and reduction performance to guide future carbon reduction strategic planning and execution.
Etron has established phased GHG reduction targets. Using the base year (2023) as the comparison baseline, the combined Scope 1 and Scope 2 emissions are planned to achieve 12% reduction by 2025, 25% reduction by 2030, 40% reduction by 2040, with the long-term goal of achieving net-zero emissions by 2050. In 2025, the Company achieved cumulative GHG reduction of 20%, outperforming the original phased target and demonstrating the progressive effectiveness of our energy management and carbon reduction measures.
Moving forward, Etron will continue to drive energy efficiency improvements, the adoption of renewable energy, and low-carbon operations management. By regularly reviewing reduction performance and implementing rolling adjustments to our management strategies, we will steadily progress toward the 2050 net-zero emissions goal, enhancing our corporate climate resilience and sustainable competitiveness.
Energy Saving and Carbon Reduction Measures
In 2025, Etron continued to promote energy-saving and carbon reduction initiatives, improving overall energy efficiency through HVAC equipment replacement, optimization of air conditioning management, and energy-saving lighting upgrades. Cumulative investments in related energy-saving projects totaled approximately NT$30,000,000. In 2025, these projects saved a total of 492,027 kWh of electricity, equivalent to a reduction of 233.22 metric tons of CO₂e emissions.

Low-Carbon Product Design
Etron continuously invests in the research and development of low-power, high-performance memory products, incorporating eco-friendly design concepts into the product development process. In 2025, we continued to advance the development of DWB (Distributed Wide Bus) products for LLM AI Edge system platforms. Utilizing Chiplet SiP (System-in-Package) heterogeneous integration technology, we simplified partial interface circuit designs to achieve the goals of miniaturization, low latency, and low power consumption while maintaining high-bandwidth transmission performance.
According to internal evaluations, under a bandwidth condition of 102.4 GB/s, DWB DRAM reduces power consumption by approximately 2.5W(Watt) compared to traditional LPDDR4 DRAM, showcasing its energy-saving benefits for high-performance computing and edge AI applications. Etron will continue to deepen low-power product technologies and high-efficiency architectural designs, assisting clients in lowering energy consumption and carbon footprints, thereby driving the development of green technology and low-carbon applications.
Renewable Energy Initiatives
Etron is committed to advancing renewable energy adoption and low-carbon transition, actively planning the installation of solar photovoltaic systems to progressively increase the share of renewable energy use and fulfill carbon reduction commitments. The installation is expected to be completed in 2026.
Once the solar photovoltaic system is completed, the use of renewable energy is estimated to reach 8% of total energy consumption. Beyond helping to reduce GHG emissions during operations, this initiative also addresses the low-carbon operation and green electricity sourcing requirements of the international supply chain. Etron will continue to pursue energy transition and renewable energy applications, steadily strengthening corporate climate resilience and sustainable competitiveness to support long-term ESG development and net-zero goals through concrete actions.
