Hitachi Construction Machinery
Global
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.
Energy-saving measures such as switching to solar power, introducing a power monitoring system (EMelia), use of inverters, and changing to LED lighting improved specific energy use by 31.5% (based on FY 2005) across the entire HCM Group in FY 2018.
We will continue to use visualization of electrical power to put effort into energy conservation to lower CO2 emissions, and move towards our mid-term goals.
Bradken has been included in the results since FY 2018.From the FY 2018 results onward, our calculations use the 2010 edition of the International Energy Agency (IEA) CO energy conversion coefficient.
Energy usage and GHG emissions that accompany everyday life
A conserving energy activities project has begun within HMC Group companies, with the goal of power usage reduction overall as well as over peak times. The use of inverters on machining tools and compressors along with the optimization of their operations etc have brought about continual improvements.

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.
