An integrated approach to managing Global Citizenship throughout the supply chain is a basic expectation of our customers and other stakeholders who are concerned about how, and under what conditions, products are manufactured. Seagate purchases products and materials from a wide range of suppliers in many geographic locations, and we expect our supply chain business partners to employ responsible, sustainable business practices in the work that they do for Seagate.
Product Environmental Performance
Seagate has used Life Cycle Assessments (LCA) as a management tool for appraising and quantifying the total environmental impact of its products and packaging over the entire life cycle of particular materials, processes, products, technologies, services or activities. Seagate has partnered with WSP Environment & Energy, an independent consultancy firm, to conduct LCAs for each of its core product types. The studies have been completed according to the ISO 14040 and ISO 14044 Framework and Guidelines for Life Cycle Analysis. They have been 3rd party critically reviewed.
Overview of LCA
A Life Cycle Assessment is an analysis of environmental impacts over a product’s life cycle from raw material extraction through end-of-life. For hard disc drives manufactured by Seagate (and packaging manufactured by third party vendors), these life cycle stages typically include the following:
LCA studies can highlight phases of the life cycle that have high environmental impact and inform the product design process to improve environmental performance.
Seagate has been developing life cycle assessments for products in each of its core market segments, including enterprise hard discs and solid state drives used in data centres, notebook and desktop computer hard disc drives, hybrid solid state drives, and portable hard drives packaged with retail enclosures. We have also conducted LCAs for retail packaging and the bulk packaging used to ship drives to our computer manufacturing customers.
Our process begins by first collecting the product bill of materials (BOM). These detailed BOMs not only show component type and mass but also report material content at the chemical substance level.
Next, LCA tools are used to model the life cycle of Seagate’s products, beginning with the materials and parts identified in the BOM. Seagate assembly plant managers provide additional data related to energy use and emissions during the assembly and testing of finished products. Transportation details are added to the models reflecting the mix of air, ocean and truck freight used during component sourcing and to distribute products to our customers.
Finally, detailed environmental impact data covering the product life cycle is generated using the ReCiPe LCA impact methodology. Each Life Cycle Assessment is documented in detailed study reports that adhere to the ISO 14044 standard for Life Cycle Assessment, and each study is critically reviewed by a third party.
