Ch2 Sustainable Development - Environment - UMC

2.2.3 Carbon Footprint
Although UMC is not an end product manufacturer, it strives to
help customers to produce green products with high quality and
achieve environmental sustainability and coexistence. In order to
establish the basis for UMC to further promote green products,
green manufacturing processes and green design, UMC has
actively implemented the Total Carbon Management Project,
internal GHG emission inventory and verification, and Carbon
Footprint Inventory Plan.
Carbon Footprint Inventory
• In the carbon footprint inventory process, UMC used product
Life Cycle Assessment (LCA) to assess the greenhouse gas
emissions of the primary material silicon, from refining and
manufacturing through production. In addition to Scopes 1
and 2 of the inventory process, Scope 3 -- Other Indirect GHG
Emissions, measure emissions from the supply chain,
employee business travel, product use and disposal, and
external waste distribution/logistics, etc., were also
measured. The major contributors of Scope 3 GHG emissions
come from the supply chain.
•UMC completed the foundry industry’s first reported carbon
footprint and EPD (Environmental Production Declaration)
verification for integrated circuit wafers produced at its
facilities in 2009. Follow-up for the whole company continued
in subsequent years.
•UMC conducted carbon footprint inventory on its 300mm
wafers at the company’s Fab 12A according to international
carbon footprint standard PAS2050/ISO14067(CD) in 2010.
• All UMC facilities completed carbon footprint inventory in
2011. The company will build upon this achievement to help
enhance the entire supply chain by vigorously implementing
green supply chain programs and helping customers to
produce green products that have lower impact on the
environment based on Carbon footprint and EPD
(Environmental Production Declaration).

Carbon Footprint
Carbon Footprint labeling informs consumers about the amount of GHG
emitted during the products' life-cycle, from raw material procurement
through manufacturing, transport, and sale and encourage them to make
sustainable purchase, ultimately contributing to carbon reductions.
