Energy and Greenhouse Gas Management
Energy Management Policy
Winbond Electronics follows the vision “Be a hidden champion in providing sustainable semiconductors to enrich human life”, implements the responsibility of green manufacturing, reduces the impact on the environment in the process of enterprise operation. While we enhance the value of products, will take into account energy conservation and use efficiency, and invest relevant resources to support equipment energy-saving optimization. We are committed to the goal of social responsibility and sustainable operation.
The Company's energy policy is as follows:
- All employee participation in energy conservation and carbon reduction, and promote plant-wide energy review.
- Implement an energy management system to ensure that energy conservation targets are met.
- Prioritize the procurement of energy-saving products and comply with energy-related laws and regulations.
- Regular energy management reviews to continuously improve energy performance.
- Increase the use of green energy year by year, and use 100% of green energy by 2050.
In 2022, our Central Taiwan Science Park (CTSP) Facility obtained ISO 50001 energy management systems certification, effectively standardizing the facility’s management processes and allowing it be managed by our engineering units. Our Kaohsiung Fab was also introduce ISO 50001 in 2023 to expand the scope and efficiency of energy management and is expected to obtain verification in 2024.
Amount of electricity saving increased about 107,896 GJ compared to 2022.
The target has not been reached in 2023 because factors such as the global economic recession have led to a decline in production capacity demand and the Kaohsiung fab has not yet reached an economic scale, which has increased the average electricity consumption per unit product. In the future, we will continue to promote equipment replacement, consumption reduction, program optimization, and smart energy-saving efficiency improvement. and other energy-saving projects to increase environmental sustainability benefits.
Target Achievement Progress
The electricity reduction target is to reduce the electricity consumption per unit product by 1% YoY per year by 2030.
| Indicators and Targets | 2023 | YoY achievement status |
|---|---|---|
| Electricity Intensity (kWh/layer - wafer photomask) | 28.0 | +22.8% |
| Electricity Intensity (MJ/layer - wafer photomask) | 100.8 |
Energy use and energy intensity for each product unit

Investment into Renewable Energy
In response to government renewable energy policies, Winbond has installed a 499 kW rooftop renewable energy generation system in 2019. In 2023, the system generated 660,000 kWh of electricity, and all electricity generated each year is sold to the Taiwan Power Company, contributing to Taiwan’s push for renewable energy.
In 2023, the system generated
Greenhouse gas management
Winbond has proactively cooperated with the government in conducting inventory and verification of greenhouse gas emissions. Winbond has implemented greenhouse gas management systems within our plant facilities, adopted the operational control approach, and adopted ISO 14064-1 standards to carry out comprehensive greenhouse gas emissions inventory and verification. Winbond has also set carbon reduction targets, looked for opportunities to reduce emissions, and proposed improvement plans.
Carbon reduction measures in 2023 are mainly FCs reduction (including process improvement to reduce usage and installation of exhaust gas treatment equipment) and electricity and energy saving (such as the use of smart air conditioners, MAU (Make-up Air Unit) water washing system optimization, Energy-saving heating belt, etc.). achieve GHG emissions reduction targets.
In addition, product carbon footprint assessment under ISO 14067 was conducted for certain IC products in 2022, gradually enhancing greenhouse gas reduction performance.
Target Achievement Progress
| 2023 | YoY achievement status | |
|---|---|---|
| Intensity of greenhouse gas emissions for each product unit (One kilogram of carbon dioxide equivalent/Layer - wafer photomask) | 15.5 | +17.4% |
Note:
- Carbon reduction targets are split into those for Scope 1 and Scope 2.
- Tier 2b calculation methods have been used to calculate the direct emissions produced by the manufacturing process in the greenhouse gas inventory report.
- The scope of data statistics is Winbond Taiwan factory.
- The target has not been achieved because factors such as the global economic recession in 2023 have led to a decrease in production capacity and the newly built factory in Kaohsiung has not yet reached an economic scale. The average emissions per unit product have also increased. In the future, we will continue to promote the reduction of process gas FCs (such as process improvement and the installation of exhaust gas treatment Equipment), electricity and energy conservation (program optimization, efficiency improvement, smart energy conservation, etc.) and the use of renewable energy and other plans to continue to reduce carbon emissions.
GHG Emissions Overview
Note: The data scope is Winbond Taiwan, and greenhouse gas emissions have been verified by third-party ISO14064.
Winbond’s goal is to have the Central Taiwan Science Park (CTSP) Facility using 90% renewable energy by 2030, greenhouse gas emissions reduced by 60%, Winbond Taiwan factory will have net zero emissions by 2050, displaying our determination to work together alongside the rest of the world to achieve net zero carbon emissions.
