Life Cycle CO2 Emissions (FY2019)

With respect to Scope 1 and 2 CO2 emissions, Japan and overseas each accounted for about 50%, and the breakdowns were also similar. For Scope 3 CO2 emissions (including energy-related fields), use of products sold accounted for a very high of 98%.
Reducing CO2emissions when sold products are used is an important issue to address going forward. In addition to reducing emissions during manufacturing, therefore, we will help lower emissions when customers use our products.

Product-Related Contribution to CO2 Emission Reduction (FY2019)

In fiscal 2019, our products contributed to reductions of CO2 emissions by a total of approximately 9,520,000 tons, of which energy-related sectors comprised 82%. We will work to improve our contributions in the transportation-related and industrial machinery sector as well, while developing technologies and other solutions based on our commitment to addressing climate change as an important business issue.
