Komatsu's Environmental and Social Activities Enhancing Quality of Life


Pursuing Environmental Management  Setting New Mid- and Long-Term Objectives

In 2010, Komatsu set mid- and long-term objectives (2015, 2020) for the production department in regards to CO2 reduction and started reduction activities. While mid- and long-term objectives for CO2 reduction is being set for the world at the COP21 in 2015, Komatsu has reevaluated its mid- and long-term objectives thus far (up to 2020) and set new mid- and long-term objectives up to 2030 in order to contribute to the environmental change measures.

Among these objectives, the stringent objectives have been set increasingly in regard to CO2 reduction particularly in domestic production, taking into consideration the electricity situation after the Great Eastern Japan Earthquake of 2011. Also, in addition to the targets set for CO2 reduction, targets will also be determined in terms of production, for our domestic and overseas factories regarding the amounts of waste generated and water input, in order to promote the efficient use of resources.

In addition, mid- and long-term objectives up to 2030 were set for logistics CO2 for the first time.

Further, in looking at CO2 generated in the life cycle of construction equipment products, we found that CO2 emissions during construction equipment use makes up appoximately 90% of total emissions. Therefore, fuel efficiency goals for construction equipment products were also set this time, up to 2030, in order to promote CO2 reduction over the entire life cycle.
