Gemtek's Taiwan headquarters and main manufacturing sites follow ISO 14064-1:2018 standards for greenhouse gas inventories. These are reviewed annually through internal audits and external verification to ensure accurate tracking. A carbon management information platform is scheduled for implementation in 2025 to enable effective tracking and management of carbon emissions data. Using 2022's total greenhouse emissions as the baseline, the company monitors yearly emissions and sets clear reduction targets. The results of the greenhouse gas emissions inventories for each facility are summarized in the table below.
Gemtek's GHG Emissions Performance (Past Three Years)
Notes：
1. Greenhouse gas (GHG) emissions data have been duly verified.
2. GHG emission types: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3).
3. The GHG Protocol used for consolidating Greenhouse Gas (GHG) emissions: Operational Control Approach.
4. Methodologies used: Global Warming Potential (GWP) factors from the IPCC AR6, the Emission Factor Method, and the Material Balance Method.
5. Calculation tools used were based on ISO/CNS 14064-1, ISO/CNS 14064-3, and the Greenhouse Gas Inventory Reporting Template Version 3.0.0 (Revised).
6. Category 1 includes liquefied petroleum gas (LPG), diesel, gasoline, natural gas, refrigerants, and BOD septic systems. Emission factors for overseas facilities are primarily based on data from the International Energy Agency (IEA), while those for Taiwan follow the greenhouse gas emission factors announced by the Ministry of Environment on February 5, 2024.
7. Category 2 covers purchased electricity. For Gemek Taiwan Headquarters, electricity emission factors are based on those announced by the Bureau of Energy, Ministry of Economic Affairs (0.474 kg CO2e/kWh for 2024; the 2023 factor remained the same as in 2022, which was 0.495 kg CO2e/kWh). The Gemtek (Kunshan) facility uses the 2022 national grid emission factor of 0.5366 kg CO2e/kWh published by the Ministry of Ecology and Environment of the People's Republic of China. The Gemtek Vietnam facility adopts the 2023 electricity emission factor of 0.6592 kg CO2e/kWh as announced by the Ministry of Natural Resources and Environment (MONRE) of Vietnam in 2024.
8. Category 3 refers to indirect emissions from transportation, including employee commuting and international business travel (air travel).
9. Category 4 refers to indirect emissions from the use of sold products, including upstream energy procurement (electricity, gasoline, diesel, natural gas, and liquefied petroleum gas) and emissions from waste disposal.
10. The Gemtek (Changshu) facility was divested in the second half of 2023; therefore, no data is disclosed for 2024.
To further disclose the results of its GHG inventory management and actively support the global 2050 net-zero target, Gemtek submitted its SBTi commitment letter in early 2025 and will adopt a science-based approach to emissions reduction planning to achieve its GHG reduction goals.In 2024, the company received a B rating on the CDP Climate Change questionnaire. Leveraging the feedback provided by CDP, Gemtek will gradually review and refine its future strategies and action plans.
To reduce future carbon emissions, Gemtek’s Taiwan Headquarters committed to a five-year (2024–2028) purchase of 500,000 kWh through Taipower’s pilot program for “Small Scale Green Energy Auction.” In 2024, the Gemtek Vietnam facility began installing rooftop solar power systems. To further increase the share of renewable energy, the company also procured 10,000,000 kWh of International Renewable Energy Certificates (I-RECs), strengthening the overall structure of its renewable energy strategy. Over the next few years, Gemtek plans to gradually increase the proportion of self-generated green energy, reduce its dependence on conventional energy sources, and ultimately lower greenhouse gas emissions. In 2024, Scope 1 and Scope 2 (market-based) GHG emissions totaled 24,657.37 tCO₂e, reflecting a 18.82% reduction compared to the base year (2022). Emission intensity for Scope 1 and Scope 2 (market-based) was 0.96 tCO₂e per NT$ million in revenue.
Carbon Reduction Action Plans
Gemtek Technology has actively engaged in green initiatives in recent years and has committed to aligning its water usage, electricity consumption, and waste generation with energy efficiency standards. The company fosters environmental awareness among employees, encouraging them to adopt a global perspective and view everyday energy conservation and carbon reduction as meaningful contributions to sustainability. In 2024, Gemtek’s energy-saving measures resulted in a total reduction of 884,518.17 kg CO₂e in greenhouse gas emissions. The company remains committed to introducing additional energy-saving practices as part of its environmental responsibility.
Gemtek's Energy-Saving Measures and Performance (2024)
Note:
1. Electricity cost savings are calculated at NT$4 per kilowatt-hour (kWh).
2. Estimated GHG emissions reduction (kg CO2e / year) = Energy savings (kWh / year) × Emission factor (Taiwan HQ: 0.474 kg CO2e / kWh; Mainland China facilities: average 0.5366 kg CO2e / kWh; Vietnam facility: 0.6592 kg CO2e / kWh).
3. Energy conversion factor for electricity = 3,600 KJ / kWh.
