Aiming for Carbon Neutrality

SMK has set medium- to long-term targets for Scope 1 and 2 emissions, aiming to achieve carbon neutrality by FY2045.

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

In addition, in line with the Electrical and Electronics Industry’s Carbon Neutrality Action Plan, we are working to improve energy efficiency in manufacturing processes, targeting an average annual improvement of 1% or more in energy consumption per unit of production value.
Regarding Scope 3 emissions, we are expanding the collection of primary data and will strengthen collaboration with suppliers to promote reduction initiatives.

Key initiatives

  • Upgrade to energy-saving facilities
  • Consideration of the expansion of renewable energy
  • Consideration of purchasing certificates or carbon credits

Progress in FY2024

CO2 emissions reduced by 50% 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 discharge and achieve zero emissions (zero landfill waste disposal), aiming for the effective use of resources.

CO2 emission factor:
  • Purchased electricity (Japan) : Factor published by the Electric Power Council for a Low Carbon Society,ELCS are used.
  • Purchased electricity (Overseas): Factors from IEA Emisson Factor 2021 are used.
  • Fuel: Factors based on the Ministry of the Environment's "Greenhouse Gas Emissions Calculation, Reporting, and Publication System" are used.
  • Past results have been revised due to the update of CO2 emission factors.

Use of renewable energy:

In May 2024, a solar power generation system was installed on the building housing the Dongguan factory. The electricity generated is consumed within the Dongguan factory. For production sites that have not yet implemented solar panel, we are considering our approach while monitoring renewable energy policies in those countries.
SMK America also purchases electricity derived from renewable energy sources. We will continue expanding the adoption of renewable energy at each site.

SMK Eco Products

Since FY2012, 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.)
