Energy Management Strategies
Upholding the duty as a corporate citizen, we spare no effort to implement environmental and social responsibilities while operating the company and developing technology. Therefore, we established the Energy Management System Promotion Committee in 2016 to actively promote the continual improvement plans and activities of various energy conservation measures. In addition, to implementing an energy management system meeting international standards, we have established an energy management policy and made the following commitments:
Continuously improve energy performance and reduce energy consumption costs.
Implement the energy management system and reduce GHG emissions.
Abide by energy regulations and prioritize procurements of energy-efficient products.
Improve the green corporate image and promote eco-design and green production.
Secure acquisition of information and resources to achieve energy and resources targets.
Energy Management System
Implemented an energy-saving project for chillers of air conditioning systems to improve the energy efficiency of HVAC operations.
Installed solar power generation systems to increase the share of renewable energy in total electricity use.
Proposed and implemented various electricity-saving measures annually, upgraded lighting and equipment, and optimized operational processes.
To improve the Company’s energy-saving efficiency, the Company continuously implemented ISO 50001 and arranged ISO 50001 internal audits and energy-saving related training courses for employees and contractors. A total attendance of 1,188 was recorded for training completion, with total training hours reaching 1,965 hours. Taiwan plants, Wujiang plants, and Coretronic Projection (Kunshan) all passed certification.
Through its management system, the Chunan plant improved energy efficiency, selected eco-friendly and recyclable materials, and established an indoor air quality monitoring system to enhance indoor air quality. As a result, it received LEED Gold Certification (LEED v4.1 for Operation and Maintenance) from the U.S. Green Building Council (USGBC), becoming Coretronic’s first plant to obtain an international green building certification.
Energy Usage Overview
To reduce energy consumption, Coretronic has implemented the ISO 50001 Energy Management System, carried out energy-saving projects for chillers of air conditioning systems, upgraded lighting and related equipment, optimized operational processes, adopted recycled materials, and developed low-carbon products. In addition, the Company has actively promoted the development of renewable energy to increase its usage ratio. Total energy consumption in 2025 was 53,028 MWh, representing a 22% reduction compared to the base year (2021), successfully achieving the short-term target. Although the addition of new production lines at Coretronic Optics (Suzhou) resulted in 24-hour production requirements and caused total energy consumption to increase by 7% compared to 2024, the long-term trend remains downward overall. Going forward, the Company will continue implementing diversified energy-saving measures to ensure ongoing optimization of energy efficiency and reduction of environmental impacts while expanding production capacity.

2025 Results
- Tainan Plant 2 Phase II project completed the installation of a solar power system with an installed capacity of 460.35 kW, which will commence electricity generation in 2026.
- Through a combination of self-generated solar power, green electricity purchased via renewable energy wheeling, and renewable energy certificates, total renewable energy usage reached 8,140 MWh, achieving a carbon reduction of 4,248 tCO2e. Renewable energy accounted for 16% of total annual electricity consumption.
Energy-Saving Measures and Performance
Since 2015, the Company has actively promoted energy management. In addition to setting clear energy-saving targets and management strategies, the Company has implemented energy-saving initiatives across three key areas: air conditioning systems, electrical lighting, and other electricity usage. These measures include improving energy efficiency, using outdoor solar-powered streetlights, controlling weekend and nighttime HVAC schedules on production lines, optimizing variable-frequency air conditioning, replacing all lighting with LED fixtures and installing variable-frequency air compressors, implementing automatic temperature control systems, and replacing transformers. In 2025, the Company implemented 19 energy-saving measures, reducing electricity consumption by 1,123 MWh and reducing carbon emissions by 565 tCO2e.
From 2015 to 2025, Coretronic implemented 408 energy-saving projects across Taiwan and China plants, reducing electricity consumption by 33,056 MWh and cutting carbon emissions by 19,000 tCO₂e, equivalent to the annual carbon absorption of 49 Daan Parks.
The Company’s electricity intensity in 2025 was 0.94, representing a 15% increase compared to 2024 but a 3% decrease compared to the base year (2021). Total electricity consumption was 50,610 MWh, representing an 8% increase compared to 2024 but a 22% decrease compared to the base year (2021), mainly due to the addition of new production lines at Coretronic Optics (Suzhou), which require 24-hour production operations. Going forward, the Company will continue strengthening energy management efforts, further improving energy efficiency, reducing carbon emissions, and advancing toward its net-zero target.
