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.
In order to ensure the reduction of CO2 emissions even under future business growth, we have changed the management indicator from "per unit of production value" to "Total emissions" from FY2024.

Carbon Neutral Target
Medium-term Target Long-term Target
FY2030: Reduce CO2 total emissions by 40% from FY2020 FY2045: Achieve carbon neutrality

Additionally, SMK is committed to improving energy efficiency in our production processes, aiming for an average 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.

Key initiatives

  • Upgrade to energy-saving facilities
  • Expansion of solar power generation equipment
  • Consider purchasing certificates or carbon credits

Progress in FY2023

CO2 emissions reduced by 40% from FY2020.
On track to achieve the medium-term target.

Energy and Resource Saving Results

Preventing global warming is considered an important management issue, and efforts are being made to improve energy efficiency.
Additionally, initiatives are in place to reduce waste and achieve zero emissions (zero landfill waste disposal), aiming for the effective use of resources.

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

Use of renewable energy:

In FY2023, we promoted the installation of solar power generation facilities at our overseas production sites. Currently, two sites in Japan and three overseas sites are using solar-generated electricity. In addition, our China works began purchasing solar-generated electricity in May 2024.

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
