Energy management
- Comprehensive Implementation of ISO 50001 Energy Management System:
Through effective implementation of the management system, Wistron conducts annual reviews of energy types and consumption within the defined management boundary. Combined with a real-time energy management dashboard, Wistron can precisely identify key points of high energy consumption and further analyze and evaluate potential opportunities for energy-saving.
- Energy Review:
Energy-saving projects are developed based on Significant Energy Uses, and energy baselines are adjusted accordingly. Regular project meetings are held to review the progress and effectiveness of energy-saving initiatives. In addition, in the event of significant changes to facilities, equipment systems, or manufacturing processes, energy baselines and management targets are updated accordingly to ensure the relevance and effectiveness of the energy management strategy.
- Cross-Site Experience Sharing:
Through cross‑site experience sharing, Wistron continues to optimize and enhance energy efficiency.

Emissions Abatement and Results
With increasing energy efficiency, low-carbon processes and innovative energy conservation, energy transitions, and internal carbon pricing, Wistron is promoting GHG reduction efforts. For the roll out of energy management and energy conservation projects, Wistron has invested people, resources, and financial resources as well as assembled Energy Project Teams in all plants; the teams are composed of units responsible for plant engineering affairs or related matters. They convene regular energy management meetings and review the plant’s energy and project progress. The plants also share information on the effectiveness and their experiences in each project with each other.
- Increase Energy Efficiency
- Low-Carbon Manufacturing and Energy Saving Innovations
Under long-term efforts to roll out energy-saving actions, Wistron’s plants have achieved remarkable carbon reduction across the six energy-saving dimensions mentioned above. Air-conditioning and air compressor power consume the most energy in Wistron manufacturing sites. As such, carbon reduction efforts seek to target these two energy consumption hotspots through taking stock of hardware equipment and diagnosing energy use. The goal of effective management is achieved through the introduction of smart energy conservation technology, combined with AI and IoT control technology in addition to replacing old energy-intensive equipment. In 2025, we saved 12,511.05 MWh of electricity. Wistron will continue to commit to low-carbon innovative manufacturing with the help of smart solutions. We are combining digital platforms and virtual factories to realize the vision of sustainable management through energy management, intelligent repair and maintenance systems, and cold water systems.
- Energy Transition
- Internal Carbon Pricing
Referencing the target carbon price range recommended by the World Bank and international carbon tax trends, the internal carbon price is set at US$100/tCO₂e. The carbon fees collected will be managed through a dedicated Climate Fund and operated on a ring-fenced basis. The fund will support two programs across business unit sites: Carbon Reduction Incentives and Carbon Reduction Investment Subsidies.
