Aiming for Carbon Neutrality

SMK has set medium- and long-term targets for Scope 1 and 2 emissions with the aim of achieving carbon neutrality by FY2045.

Carbon Neutral Target

● Medium-term Target
FY2030: Reduce CO2 emissions per unit of production value
             by 40% from FY2020

● Long-term Target
FY2045: Achieve carbon neutrality

Additionally, SMK is committed to improving energy efficiency in our production processes, aiming for an annual improvement rate of 1% or more in energy consumption per unit of production value, in line with the Electrical and Electronics Industries' Carbon Neutrality Action Plan by the Liaison Group of Japanese Electrical and Electronics Industries for Global Warming Prevention.

Key initiatives

● Upgrade to energy-saving facilities
● Install solar power generation systems
● Choose low-carbon power options

Progress in FY2022

CO2 emissions per unit of production value reduced by 33% from FY2020.
On track to achieve the medium-term target.

FY2022 Environmental Conservation Activities

Preventing Global Warming

By promoting energy-saving improvements, All targets for energy consumption and per unit of production value *1, and CO2 emissions and per unit of productio value *2 were achieved.
In addition to updating to energy-saving equipment, which has been a traditional activity, solar power generation equipment was installed at the Toyama works and the Hitachi works.

Biodiversity Conservation

SMK implemented a curriculum related to environmental conservation in an internship program for junior high school students.
On the other hand, before the the coronavirus pandemic, the environmental study course for nearby elementary school students was held evey year, but it could not be held in FY2022 in order to prevent the spread of infectious diseases and will be held in FY2023.

Effective Use of Resources

Targets for waste discharges and per unit of production value *3were achieved through promotion of waste elimination activities in the manufacturing process.
The target for landfill disposal was also achieved by promoting recycling at overseas production sites.

Ensuring Environment-related Substance Management

The management system for chemical substances in products was regularly upgraded and made more efficient.

Energy and Resource Saving Results

We are working to improve energy efficiency with the prevention of global warming as an important management issue.
We are also working to reduce the amount of waste and achieve zero emissions (zero landfill disposal of waste), aiming for effective use of resources.

  • ・Past results have been revised due to the update of CO2 emission factors.

<Installation of solar power generation equipment>
Solar power generation facilities have already been installed at Philippine works., and furthermore, solar power generation facilities were newly installed at domestic production sites in FY2022. The power generated is consumed in-house, leading to a reduction in CO2 emissions.

SMK Eco Products

Since fiscal 2012, we have established internal criteria for SMK Eco Products.
Eco products consist of "Eco-contributing products," which are classified by the end market of customer products, and "Eco-friendly design products," which are evaluated based on the level of environmentally friendly design.

  Deatails
SMK Eco Products Eco-contributing products SMK products used in products for environmental markets as defined by internal standards
Eco-friendly design products SMK products that meet internal standards for energy conservation and higher efficiency, resource conservation, environmental protection and eco-friendliness, and reduced load on manufacturing processes 
Percentage of sales of Eco Products

*SMK Eco products =Eco-contributing products plus Eco-friendly design products
  (If both are applicable, they will be counted unduplicated.)
