TDK: CALCULATING HOW MUCH CO₂ EMISSION IS REDUCED BY AN ELECTRONIC COMPONENT

A key initiative in its Environmental Vision 2035, TDK is helping to steer society toward higher energy efficiency by enumerating the contribution made by the components it manufactures to CO₂ (carbon dioxide) emission reductions.

TDK’s unique calculation methodology
TDK has championed the concept of Product Contribution and is already engaged in efforts to quantify contributions to the environment. Here is how the calculation works.

First, using an earlier product as a benchmark, a new product’s energy and fuel savings achieved through its lower power consumption, smaller size, and lighter weight are derived, followed by a per-component calculation of CO₂ emissions reduction. That number is multiplied by the annual sales volume of the component to arrive at the total amount of CO2 reduced—or Product Contribution.

TDK’s total Product Contribution is computed from direct contributions made by its own products and indirect contributions made by the usage of its customer’s products and services.



The concept of Product Contribution: By calculating the amount of CO₂ reduced through efficiency improvements and weight reduction in energy-saving products and multiplying them by annual sales volumes, the amounts contributed to the reduction of CO2 can be broken down by industrial sector and by product group.

Strengthening the competitiveness of electronic components through environmentally-conscious product development and rule-making
TDK has designated its products that are especially effective and industry-leading in reducing environmental impact as Eco Love Products and those at the very top level in the industry as Super Eco Love Products.




With the progress of DX (Digital Transformation) and EX (Energy Transformation), the environmental contribution of electronic components is expected to continue rising in importance. TDK is working to create products with even better environmental performance and to establish common rules in the electronic components industry for measuring environmental contribution.
