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 is also planned to undergo ISO 50001 certification, with the hopes of expanding the scope and benefits of our energy management operations. 

Amount of electricity saving increased about 129,229 GJ compared to 2021.This was due to the global economic deterioration in 2022 leading to lower demand, in turn causing the average electricity consumed to produce one product unit to slightly overshoot our target levels. In the future, Winbond shall continue to promote energy conservation plans to reduce the burden on the environment.

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 2022, 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 2022, 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 2022 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, 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.
 

In 2022, Winbond completed ISO 14067 carbon footprint inventory and verification of a portion of our IC products.

Target Achievement Progress

 2022 Targets2022 Achievements
Intensity of greenhouse gas emissions for each product unit
(One kilogram of carbon dioxide equivalent/Layer - wafer photomask)
≦13.313.2

Note:

  1. Carbon reduction targets are split into those for Scope 1 and Scope 2.
  2. Tier 2b calculation methods have been used to calculate the direct emissions produced by the manufacturing process in the greenhouse gas inventory report.
  3. The scope of data statistics is Winbond Central Taiwan Science Park (CTSP) FAB, The Kaohsiung Fab was newly-established and began operations in 2022, so it has not been included in this year’s calculations of greenhouse gas emissions intensity per product unit.

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.

2030 goal:Achieve 90% of electricity consumption as renewable energy in CTSP Fab.
2030 goal:Greenhouse gas emissions reduced by 60% in CTSP Fab.
2050 goal:Achieve 100% of electricity consumption as renewable energy in Winbond Taiwan factory.
2050 goal: Net-zero emissions from Winbond Taiwan factory.
