Environmental Sustainability

Winbond has worked alongside countries and companies from around the world to implement green sustainability measures, proactively reducing the impact that our business operations have on the environment. Apart from having no major violations of environmental laws, Winbond has also committed innovative new technologies and significant resources into adopting measures for reducing energy consumption and carbon emissions, improving resource utilization rates, and improving waste and emissions management, taking concrete action to implement our sustainable development blueprint.

Energy and Carbon Emissions Management

Energy and Greenhouse Gas Management

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.

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.

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

Target Achievement Progress

2022 Targets 2022 Achievements
Intensity of greenhouse gas emissions for each product unit
(One kilogram of carbon dioxide equivalent/Layer - wafer photomask)
≦13.3 13.2
  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 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

Winbond’s goal is to have the Central Taiwan Science Park (CTSP) Facility using 90% renewable energy by 2030, 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.
