Energy and GHG Management
Environmental and Energy Management System
GIS introduced the ISO 50001 Energy Management System in 2015, and in December of the same year, both GIS (Chengdu) and GIS (Shenzhen) passed the verification. The Energy Management Team conducts regular reviews of the energy usage status across all energy-consuming units and systems. Based on GIS’s operational environment, the team proposes improvement measures and formulates annual energy management goals along with performance parameter monitoring plans. GIS plans to regularly invite third-party verification organizations to conduct reviews to ensure the continued validity of its certification. GIS (Chengdu) has the latest certificate validity period until December 16, 2027, while GIS (Shenzhen) has the latest certificate validity period until December 29, 2026.
GIS has also implemented the ISO 14001:2015 Environmental Management System, with ISO 14001 certification completed in 2025 for six operating sites including Taiwan and China Factories. The company has also completed triennial certification renewal audits, with the verification covering 100% of employees and workers. The latest certificate is valid from November 14, 2025, to November 13, 2028.
ISO 14001 & ISO 50001 Certifications
Clean Electricity
GIS primarily consumes electricity, gasoline, and diesel, with electricity accounting for 99.64% of total energy consumption. In response to stakeholder expectations, the Company actively promotes the use of clean energy. As early as 2020, GIS signed a green power usage agreement with stakeholders, committing to 100% green power use for product manufacturing and related activities within the group. In 2024, GIS further pledged to achieve 100% green power usage across the entire group by 2030 – a target that has been approved by the SBTi.
GIS Energy Mix
From 2022 to 2025, GIS's factories in Mainland China achieved 100% green power usage for four consecutive years. In 2025, the overall green power usage rate across all factories reached 86.45%, aligning with the Company's short-term target set in the roadmap.
GIS Renewable Electricity Targets and Actual Usage Share Roadmap
GIS Mainland China Plant: In 2025, a total of 202 million kWh of green electricity was purchased in Mainland China (including Chinese Green Electricity Certificates (GEC), direct power purchase agreements (PPA), and hydropower environmental attributes), reducing or offsetting 107,577.6 metric tons of CO2 emissions.
GIS Taiwan Plant:In 2023, the Company invested NT$159 million in the construction of a solar power generation system at its Houli site. In 2025, the system generated approximately 3.76 GWh of electricity, which was sold to other entities under a feed-in arrangement.The Company also plans to implement a rooftop solar power generation project at its Chengdu site. Construction is scheduled to begin in June 2026, with grid connection and power generation expected in October 2026. The project is estimated to generate approximately 5.7 GWh of electricity annually.
Energy-Saving Projects
In 2022, a total of 80 energy-saving projects were implemented, saving 19.6 GWh of electricity.
In 2023, a total of 44 energy-saving projects were implemented, saving 12.9 GWh of electricity.
In 2024, a total of 40 energy-saving projects were implemented, saving 17.5 GWh of electricity.
In 2024, a total of 34 energy-saving projects were implemented, saving 13.4 GWh of electricity.
Greenhouse Gas Management
GIS conducted its first carbon inventory in 2019 and expanded and refined its inventory scope in 2022, referencing ISO 14064 and the GHG Protocol, with 2022 serving as the base year. GIS plans to conduct regular annual greenhouse gas inventories covering the company and its subsidiaries, with all relevant data verified by a third party.
GIS passed the SBTi audit in March 2023. By 2030, with 2022 as the base year, GIS aims to achieve an absolute 42% reduction in both Scope 1 (direct emissions) and Scope 3 (upstream and downstream emissions along the value chain). This will result in a 5.25% annual reduction in total Scope 1 and Scope 3 carbon emissions compared to the previous year. Green electricity consumption is also targeted to reach 100% by 2030.
Compared to 2022, in 2025, Scope 1 emissions decreased by 64.14%, green power usage reached 86.45%, and Scope 3 emissions decreased by 41.97%, meeting SBTi requirements.
Scope 1 Reduction Roadmap
Scope 3 Reduction Roadmap
In 2025, GIS reviewed seven major GHG categories: carbon dioxide (CO2 ), methane (CH4 ), nitrous oxide (N2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6 ), and nitrogen trifluoride (NF3 ). Based on these categories, a comprehensive GHG emissions inventory check was compiled.The GIS carbon emission data is as follows:
GIS Emissions Over the Past Three Years
GIS is committed to achieving an absolute reduction of 42% in Scope 1 and Scope 3 emissions by 2030, using 2022 as the base year, requiring an average annual reduction of 5.25% for both Scope 1 and Scope 3. Statistical data shows that the Company has achieved this year's reduction targets for both Scope 1 and Scope 3. The Company plans to further introduce more proactive carbon reduction measures within its operational scope, such as installing methane collection devices on septic tanks, adopting refrigerants with lower Global Warming Potential (GWP) values in newly purchased air conditioning equipment, and promoting the electrification of fuel-powered vehicles. Regarding the value chain, the Company will also conduct greenhouse gas inventories to urge carbon reduction actions among its suppliers.

Carbon Credit Trading
From 2018 to 2024, in response to the tightening carbon quota policies in Shenzhen, the Shenzhen Factory has achieved a 100% compliance rate for seven consecutive years, demonstrating high resilience in carbon management. Through the continuous advancement of renewable energy use and energy efficiency improvement projects, the actual carbon reduction benefits of the Shenzhen Factory are remarkable. The actual carbon emissions have significantly decreased from 104,930 tons in 2018 to 42,359 tons in 2024, achieving an overall carbon emission reduction of as High as 59.6% over the 7 years. While actively reducing emissions, the Company also flexibly utilizes market mechanisms to transform environmental performance into tangible financial contributions. And profited approximately NT$ 3,000,000 from selling carbon credits.
