Expand Environmental Contribution of Products

Background of Goals

In 1997 TDK introduced product assessment to evaluate the environmental impact of products throughout their whole lifecycle. Only products that receive certification in this product assessment screening are commercialized and distributed in the market. Furthermore, as a measure designed to continuously create products with high environment-conscious effects, in 2008 TDK introduced a system whereby products that are deemed on the basis of the product assessment results to be excellent environment-considerate products are designated as ECO LOVE products. TDK discloses information about these ECO LOVE products on its website. Its target was for such products to account for 30% of sales in fiscal 2011, double the figure of 15% in fiscal 2009.* By achieving this target, TDK promoted the creation and diffusion of products contributing to a reduction of the environmental load.
In addition to these existing activities, TDK focuses on the contribution of products and know-how to the reduction of CO2 emissions in society. TDK is in the process of establishing computing criteria for quantifying this environmental contribution in fiscal 2011, and in fiscal 2015, we formulated a set of guidelines for calculation of product contributions that reflect the results of our compilation efforts. By means of continued product assessment activities, we are aiming to promote the reduction of CO2 emissions through products.

Fiscal 2018 Goals and Achievements


  • Improve product-based CO2 reduction contributions basic-unit by 2.7% compared with the previous FY


  • Worsened by 3.1% compared with the previous FY

Main activities and measures

  • Calculate amounts of product contributions of new products
  • Integrate the guidelines for contribution amount calculation intonew products assessment system

Product-based CO2 reduction contributions in fiscal 2018 amounted to 2.149 million tons, up 5.2% from the previous FY, and CO2 reduction contributions basic-unit worsened by 3.1% compared with the previous FY. Thus, our goal was not achieved

Future Activities

We will strive to develop environment-contribution products that contribute to reducing impact on the environments of customers and society and will expand the spread of our products by emphasizing their value.

Automotive MLCCs contribute to reducing environmental load

TDK has miniaturized and increased the capacity of multilayer ceramic chip capacitors (MLCCs) through adoption of ultra-fine structures made possible by advanced materials technologies and advanced layering technologies that enable the production of 1,000 layers. As a result, MLCCs are used many common products such as automobiles, consumer electronics, and information and communications devices.
As a result of miniaturization of products used in automobiles, the environmental contribution of MLCCs is equal to 19,162 tons when converted to CO2. We expect that this contribution will increase even further as environmentally friendly vehicles are used more widely.
