FY2017 Environmental Preservation Activities

● Preventing Global Warming

CO2 emissions per unit of production increased due to an increase electricity usage in line with the promotion of in-house production at some overseas factories. The total CO2 emission was reduced but the planned reduction target was not achieved.

● Preserving Biodiversity

SMK held environmental learning courses at both domestic and overseas to learn about the effects of changes in the global environment on living things focusing on children from local communities.

● Effective Use of Resources

lthough SMK promoted activities aimed at eliminating MUDA (wasteful and/or inefficient areas, actions, materials, etc.) in manufacturing, both our industrial waste discharge per unit of production and total waste discharge increased due to an increase in waste discharge stemming from the relocation of some overseas factories.
Landfill waste targets were achieved.

● Effective Responses for the Management of Environment-related Substances

In FY2017, SMG established a working group to promote in-house development of its bill of material (BOM) information system.

In addition, explanations about the system were provided at some overseas factories. SMK plans to continue developing and further establishing the system domestically and overseas.

● Strengthening Eco-friendly Design Approach

In FY2017, SMK created integration evaluation standards for product assessment and eco-products.
During the current fiscal year, SMK will change its management system aimed at actual integration.

*¹: CO2 emissions per unit of production value = CO2 emissions divided by production value
*²: Industrial waste discharge per unit of production value = industrial waste discharge divided by production value

Material Balance

At SMK, we work to track, analyze, and reduce the material balance (environment footprint) of each process throughout the Group, from product design and development to manufacturing and sales.

Consideration for Water Resources

Using the World Resources Institute's (WRI) Aqueduct water risk mapping tool, we analyzed water risk at SMK's Head Office and all production locations. The results showed that there is no SMK location with a very high water risk present.
SMK was able to confirm regionality and unexpected risk factors using various indicators such as water volume, water quality, water usage regulations, etc.
We will continue with water conservation efforts by examining beneficial measures for water conservation after understanding the water risk for the region of each site.
