Climate Change Initiatives
Evaluation of carbon footprint (CFP) and utilization

Focusing on circular economy using recycled materials with low CO2 emissions
Starting trial CFP evaluations from the standpoint of ensuring future transparency through utilization of digital technology• It is possible to understand GHG emissions within the product life cycle and manufacturing process• It is also possible to compare GHG emissions in manufacturing from natural resources compared to that of recycled materials• Achieving product differentiation in response to customer needs amid increasing demand for Scope3 calculation

product processing at Wakamatsu Plant

Future plans

Trial comparative calculation of a conventional precipitation-type process, which requires
high-temperature, long-term heat treatment GHG emissions for the MSP1 copper alloy
manufacturing process used in small in-vehicle terminals• CFP in consideration of tungsten recycling• CFP in consideration of copper scrap rawmaterials

The carbon footprint is extracted from evaluation items related to GHG emissions in LCA**LCA (Life Cycle Assessment): A method of quantitatively evaluating input resources, environmental load and related environmental impact within a product’s life cycle
