What is a material balance?
The material balance shows the overall picture for energy and resources used in the process of Casio’s business activities including R&D, design, parts procurement, manufacturing, distribution, recovery and recycling, and the energy used in the process of product use by customers (inputs) plus the environmental impacts that are produced in each of those processes (outputs).
In order to ensure the reliability of its environmental data reporting, in fiscal 2011 Casio began requesting third-party verification.
Casio commissioned SGS Japan Co., Ltd. to conduct the audit in fiscal 2020. The audit covered greenhouse gas emissions (Scope 1, 2 and Categories 1, 4 and 11 of Scope 3), water intake, waste and emissions of atmospheric pollutants (NOx, SOx and dust). Of the sites covered by SGS, on-site surveys were conducted at the Yamagata Casio Co., Ltd. (Yamanashi) and Hamura R&D Center.
Sites at which water usage and waste were difficult to ascertain, such as leased offices, are not included in the scope of calculation.
