Winbond environment policy

There have been no significant environmental accidents or violations that resulted in the release of chemicals to the environment at the the organization site within the past three years.

Verification and reduction of greenhouse gas emission

Target: Taking 2010 as the base year, 8% reduction of emissions per unit of product by 2020(≦ 15.1 kg CO2e/layer).

2018: GHG emissions 341,789 ton CO2e; GHG emissions per unit of product 15.2 kg CO2e/layer

2017: GHG emissions 313,177 ton CO2e; GHG emissions per unit of product 15.9 kg CO2e/layer

2016: GHG emissions 269,974 ton CO2e; GHG emissions per unit of product 14.8 kg CO2e/layer

According to GHG Protocol (The Greenhouse Gas Protocol) and ISO 14064-1, Winbond has established the complete list of the greenhouse gas emission. The verification is ranging from, Scope 1-(direct emission of greenhouse gas), Scope 2-(indirect greenhouse emission), the verification of qualitative and quantity, Scope 3-other indirect greenhouse gas emission, the main emission qualitative verification. According to the statistics, the greenhouse gas emission of Winbond is mainly from the outsourced electric power that company demand. CO2 will be generated by the process. Also produce greenhouse gas while manufacturing semiconductor by using PFCs (Perfluorocarbons) including CF4, C2F6, SF6, NF3, CHF3, C4F8, etc. The result of greenhouse gas emission quantities passes the examination, confirmed by the third party every year.

The mainly emission of manufacturing stage comes from PFCs and electric power. Therefore, focusing on reducing PFCs gas and electric power not only reduce the overall amount emission of greenhouse gas efficiently but also can reduce the carbon footprint of products.

The promotion of reducing PFCs plan and measurement, as follows:

Electricity management

Target: Electricity usage per unit of product by 2020 is lower than 2010(≦ 22.99 KWH/layer).

2018: Electricity usage per unit of product 22.12 KWH/layer

The plants are constructed based on energy-saving designs that help save energy in the plant management system. Using a supervisory control and data acquisition system (SCADA), energy use data are monitored and analyzed to achieve optimal management on energy reduction. Continuously promote energy-saving measures to reduce energy use.

Water management

Target: Water usage per unit of product is lower than 150 L/layer and water reuse rate is higher than 80% until 2020.

2018:  Water usage per unit of product 139 L/layer; water reuse rate 82%

We establish a design for water supply and reclaim pipeline system; implement a 24-hour all-time control and monitoring system to monitor water use across the plant; renew water-saving plans annually and review effectiveness regularly.

Waste management

Target: Waste recycling rate is higher than 90% until 2020.

2018: Waste recycling rate 92%

We reduce the amount of waste by reducing the use, reuse and recycling of waste. Recycling and reuse are given a priority for consideration in waste disposal to minimize impacts on the environment. Make annual plans of waste abatement, and review the effectiveness on a regular basis.
