Komatsu's Environmental and Social Activities Enhancing Quality of Life


Pursuing Environmental Management  Setting Mid- and Long-Term Objectives

While long-term objectives for CO2 reduction was being set for the world at COP21 in 2015, in order to contribute to the climate change measures as Komatsu, we set medium- and long-term objectives (2020, 2030) and determined to begin in FY2016 to take action based on these objectives.

In looking at CO2 generated in the life cycle of construction equipment products, we found that CO2 emissions during construction equipment use makes up approximately 90% of total emissions. Therefore, this time we are working on reducing CO2 emissions over the entire life cycle of construction equipment, and have set fuel efficiency goals for construction equipment products that are to be achieved by 2030.

In terms of CO2 reduction for domestic productionóconsidering the electricity situation that resulted from the Great Eastern Japan Earthquake in 2011ówe have set increasingly stringent objectives. Also, for production, in addition to the targets set for CO2 reduction, we set targets for our domestic and overseas factories regarding the amounts of waste generated and the amounts of water input, in order to promote efficient use of resources. And we set medium-term targets up to 2030 for CO2 in logistics.
