Greenhouse Gas / Materials Balance
The Hitachi High-Tech Group is working on reducing CO2 value chain emissions, including CO2 emissions resulting from energy use at its business sites (Scope 1 and 2) and CO2 emissions elsewhere (Scope 3), as a response to the risks of climate change.
In order to enhance the credibility of this report, FY2021 figures marked with have received independent assurance from SOCOTEC Certification Japan Co., Ltd. in accordance with the International Standard on Assurance Engagements (ISAE) 3000 and ISO14064-3.
