GlobalWafers Co., Ltd. (GlobalWafers), upholding the principle of “Responsible Growth,” has officially committed to science-based carbon reduction targets under the Science Based Targets initiative (SBTi), pledging to achieve net-zero greenhouse gas emissions across its entire value chain by 2050.
The Science Based Targets initiative is an internationally recognized benchmark for low-carbon transition. It helps companies and organizations set emission reduction targets aligned with the latest climate science, ensuring consistency with the Paris Agreement’s decarbonization requirements to limit global warming to 1.5°C above pre-industrial levels, or well below 2°C.
Following the signing of the SBTi commitment, GlobalWafers will submit its target plan in accordance with SBTi’s Absolute-based Approach. To actively implement its net-zero roadmap, GlobalWafers not only follows the Science Based Targets initiative with an ambitious decarbonization pathway covering direct, indirect, and value chain emissions, but also officially announced in June 2025 the acceleration of its renewable energy transition. The company advanced its RE100 target for achieving 100% renewable energy across all subsidiaries from the original 2050 deadline to 2040, with net-zero emissions to be achieved by 2050.
To effectively manage climate-related risks and opportunities, GlobalWafers continues to deepen green manufacturing at its global sites. This includes optimizing production processes, enhancing energy efficiency of products and equipment, and upgrading or replacing existing systems to achieve energy-saving and carbon reduction goals. For example, GlobalWafers’ Italian plant has strengthened the performance of its cogeneration system to optimize electricity, heat, and cooling water usage. It also plans to gradually replace natural gas with biomethane and recover hydrogen from process exhaust gases, significantly reducing carbon emissions.
In terms of renewable energy adoption, GlobalWafers formally joined the RE100 initiative in 2022 and has set phased milestones under its climate roadmap to achieve 100% renewable energy by 2040. The company is expanding renewable energy use through self-built solar power plants, signing Power Purchase Agreements (PPAs), and purchasing Renewable Energy Certificates (RECs). Its new facilities have incorporated energy-saving measures from the construction phase and actively utilize renewable energy. Subsidiaries worldwide also continue to increase renewable energy usage in line with local energy policies. For instance, GlobalWafers’ Danish subsidiary, Topsil, commissioned its solar power facility in 2025, becoming the world’s first semiconductor crystal manufacturing site powered entirely by self-generated renewable energy. Meanwhile, the new fab in Texas, the Missouri plant, and the new production lines in Italy will run on 100% renewable energy once mass production begins, delivering low-carbon wafers that combine advanced technology with sustainability.
On value chain decarbonization, GlobalWafers actively engages with both upstream and downstream partners on future emission reduction pathways, climate initiatives, and energy management. For raw material suppliers, the company classifies them based on carbon emissions and drives them to conduct product carbon footprint assessments and set emission reduction targets, with regular progress tracking. On the customer side, GlobalWafers collaborates with key value chain partners to align decarbonization strategies and commitments under the SBTi. The company also actively participates in global semiconductor industry association meetings to expand its influence to end customers, ensuring that its decarbonization pathway fully encompasses the entire value chain.
GlobalWafers Chairperson Doris Hsu stated: “Facing the global challenge of climate change, we recognize the critical responsibility borne by the semiconductor industry. Based on science, GlobalWafers is committed to advancing carbon reduction and renewable energy transition, while working hand-in-hand with our value chain partners to achieve net-zero by 2050. We are determined to implement concrete actions for sustainable development, creating long-term value with positive impact on the environment, society, and the economy.”
