Product Life Cycle Assessment

 

The product life cycle assessment (LCA) refers to the assessment of potential environmental impacts caused by the investments in and outputs of raw material, manufacturing, distribution, use, and end of life stages of products and services. Corporations can use LCA to assess all the impacts on the environment created by products “from cradle to grave”, such as contributions to global warming and damage to the ozone. The assessment results can be applied to products, manufacturing and services to achieve the purpose of continuously providing environmentally friendly products.



Wistron complies with ISO 14040 and 14044 life cycle assessment standards to assess our products. The scope of the system boundaries has been defined according to the product category rules (PCR) for IT equipment by the EU Environmental Footprint Category. The boundaries have been defined as cradle to grave, which includes raw material, manufacturing, distribution, use, and end of life stages. The LCA analysis software is used to conduct the computational analysis to obtain the environmental impact assessment results and carbon footprint of the product. Currently, products that have completed LCA analysis account for 22.50% of Wistron's total revenue.

Wistron established a standard operating procedure for product life cycle assessment. Our colleagues are trained through e-learning classes, and we established an LCA analysis team to continue to strengthen the knowledge and capabilities of our product life cycle assessment. In addition, Wistron's Product Carbon Footprint System (PCF System) was officially launched in January 2023. It obtains product-related information by connecting Wistron's internal systems, allowing for rapid calculation of carbon footprint and significantly reducing the manual work time for life cycle assessment. The system also enables carbon emission hotspot analysis to assist the product development team in developing low-carbon products.

In 2023, Wistron completed carbon footprint calculations for a total of 30 laptop models through the PCF system, accounting for 3.79% of Wistron's total revenue.
