GlobalWafers, one of the world’s top three semiconductor wafer manufacturers, officially announced today (June 17) that it will advance the RE100 goal of achieving 100% renewable energy use for all its subsidiaries from the original target of 2050 to 2040, a full ten years earlier. This bold commitment demonstrates GlobalWafers’ determination to accelerate its green transformation and actively respond to climate change, and it will also work with the semiconductor supply chain through concrete actions to embrace a sustainable future.
RE100 is a global renewable energy initiative jointly launched by The Climate Group and CDP (Carbon Disclosure Project), gathering the power of enterprises worldwide to promote the use of renewable energy and energy transition. To implement the business philosophy of “Responsible Growth,” GlobalWafers has voluntarily declared since 2021 that it would achieve the goal of 100% renewable energy use by 2050, and officially joined the RE100 initiative in 2022. Facing the challenges of global climate change, GlobalWafers, as one of the world’s leading semiconductor wafer manufacturers, is not only a trusted supply chain partner for its customers but will also contribute to promoting industrial development and environmental sustainability. GlobalWafers proactively advanced its RE100 target timeline by a significant 10 years, and more actively adjusted its phased targets, updating the milestones for the entire group’s renewable energy usage ratio from 20% in 2030, 35% in 2035, 50% in 2040, and 100% in 2050 to 35% in 2030 and 55% in 2035, with the entire group using 100% renewable energy by 2040. Through comprehensively accelerating the increase in renewable energy utilization rates at each operational site and continuously reducing carbon emissions from electricity consumption, GlobalWafers demonstrates its commitment to net-zero carbon emissions and firmly responds to environmental sustainability with practical actions.
To expedite the achievement of its 100% renewable energy target, GlobalWafers is pursuing a dual-track approach. On the operational front, in addition to reducing the energy consumption of existing equipment and continuously optimizing the efficiency of major energy-consuming equipment. Concurrently, production sites worldwide are aligning with the group’s energy transition roadmap. Through a range of initiatives—including diverse strategies such as installing solar panels, introducing alternative clean energy, signing power purchase agreements (PPAs), and acquiring renewable energy certificates (RECs) —is enabling the group to meet its RE100 commitment ahead of schedule. At the same time, GlobalWafers is also leveraging the rich experience of its parent company, Sino-American Silicon Products, in the renewable energy sector and its vertically integrated supply chain to significantly boost the share of green energy usage.
GlobalWafers remains committed to strengthening green manufacturing, with its global facilities actively driving efforts in energy conservation, carbon reduction, and low-carbon transformation—achieving notable progress. GlobalWafers’ Danish subsidiary, Topsil GlobalWafers A/S (Topsil), officially commenced operations of its self-built solar power plant in 2025, becoming the world’s first semiconductor crystal growth factory to use 100% self-generated renewable energy for internal use, with the capability to export excess power to the local grid—making it the group’s first site to fulfill the RE100 objective. Simultaneously, GlobalWafers’ global production sites, including factories in Taiwan, Japan, and Korea, have rolled out installation of solar power generation systems, actively increasing the proportion of renewable energy use. Newly constructed plants and expanded production lines have introduced various energy-efficient equipment from the construction phase, incorporating diverse sustainability solutions to maximize renewable energy adoption. GlobalWafers’ US greenfield expansion in Texas, along with the newly expanded production lines in Missouri and Italy, are expected to manufacture the world’s most advanced silicon wafers using 100% renewable energy during the capacity ramp-up stage. Among these, the Italian site, through its participation in the national “Energy Release” program, is expected to source approximately 42,000 MWh of renewable electricity annually at stable prices (in line with pre–Russia-Ukraine crisis market levels). The share of renewable energy is also increasing through measures such as the signing of Power Purchase Agreements (PPAs) and the installation of photovoltaic systems. In parallel, efficiency improvements to the existing cogeneration system are planned to optimize the use of electricity, heat, and chilled water. Additionally, a plan has been defined for the gradual replacement of natural gas with biomethane, along with projects to recover hydrogen from process exhausts—effectively reducing carbon emissions. In 2024, renewable electricity accounted for 34% of total energy consumption across the Italian sites, with full RE100 alignment expected by 2031. Furthermore, GlobalWafers is actively promoting value chain carbon reduction by engaging with major customers on carbon reduction planning and the adoption of renewable energy, working with industry partners to build a low-carbon resilient supply chain.
Chairperson of GlobalWafers, Doris Hsu, stated: “GlobalWafers’ formal announcement to bring forward the group’s 100% renewable energy goal by a decade clearly reflects our determination and commitment to driving a green transition. In response to the global momentum around ESG, we firmly believe that embracing sustainable manufacturing is not only part of our corporate responsibility, but also a critical factor in strengthening our long-term competitiveness. GlobalWafers will continue advancing renewable energy infrastructure, increasing clean energy adoption, and enhancing operational efficiency. By leveraging our global footprint, we aim to deliver semiconductor wafers with minimal carbon mileage and a significantly reduced product carbon footprint, collaborating with partners across the value chain to accelerate the shift toward a low-carbon economy.” GlobalWafers remains dedicated to environmental sustainability and will uphold this commitment through impactful efforts. By expanding renewable energy usage, curbing carbon emissions, and reinforcing eco-friendly manufacturing practices, GlobalWafers strives to shape a sustainable future alongside our global customers and partners.
