Hitachi Construction Machinery


Production (Scope 1&2)

To contribute to the prevention of global warming, HCM Group is working to reduce the CO2 emissions generated by energy which accompanies business activity. We receive third-party evaluation for GHG emissions based on criteria of verification ISO 14064-3 at limited level of assurance.

In the FY 2019, HCM Group reduced energy consumption by 13% compared to the previous year thanks to energy-saving measures such as switching to solar power generation, introducing a power monitoring system (EMilia), use of inverters, and changing to LED lighting. Total CO2 emissions decreased by about 1% compared to the previous year.

Tata Hitachi Construction Machinery switched the company’s power generation to photovoltaic power generation and in the FY 2019, renewable energy accounts for more than 40% of its electric power consumption.

Carbon Offset Initiatives

HCM is spreading the use of products with high-level energy-saving functions, and we are taking carbon offset initiatives in order to contribute low-carbon society .

Ongoing Initiatives

In the interests of reducing CO2 emissions from energy going forward, we are not only furthering the systematic introduction of high-efficiency machinery and fuel conversion, but we are also attempting to raise environmental awareness through monitoring the monthly results of CO2 emissions at each company or group company and uploading goal achievement states online for visibility. In the future, we will establish a structure that evaluates the undertakings towards achieving annual targets, and will endeavor to strengthen the PDCA.
