Komatsu's Environmental and Social Activities Enhancing Quality of Life


A Message from the Environment Supervisor: Desire to contribute to sustainable development while providing a richer life for people.

── Tell us about establishing new mid- and long-term objectives.

In regards to CO2 emissions, each country is setting new objectives for 2020 and beyond in preparation for COP21. Accordingly, Komatsu has also established new mid- and long-term objectives for 2020 and 2030. In setting these objectives, we took into consideration not only CO2, but our products life cycle, including fuel consumption of products, waste and water input as well as efficient use of resources.

When looking at CO2 in terms of lifecycle, it has been estimated that 90% of all emissions comes from construction equipment products, making it clear the importance of reducing this amount. In addition, while aiming for further growth in productivity, we have set even more aggressive target values for CO2 emissions from production. We have also set targets for waste and water input, in order to work towards the efficient use of resources, not only for our plants in Japan but for our plants all over the world.

── Tell us about CO2 reduction in construction equipment products.

In terms of how to reduce CO2 emissions from construction equipment, we have developed products such as hybrid construction equipment that have excellent fuel efficiency. In 2015, our sphere of activity has been expanded further to include the way in which construction equipment is used, so that we can now offer the new solution “SMART CONSTRUCTION”. This is a solution that provides an automated control of innovative work equipment, a revolutionary topographical survey technology, and a system called “KomConnect” to connect data, in order to dramatically improve efficiency on the work site through topographical survey, design, construction management and use of highly advanced automated ICT construction equipment. Based on this development, efficiency can be dramatically improved, and CO2 emissions from construction equipment will also be greatly reduced.

── How are you engaging in the activities involved in production?

The electricity reduction activities that started after the Great East Japan Earthquake of 2011 are progressing to meet the objectives set for 2015.

In 2014, we took a major step forward with the start-up of Awazu’s new assembly shop making groundbreaking configuration and high levels of energy conservation capabilities a reality, and with the use of biomass heat supply and electric power generators being instituted at the Awazu plant. Biomass handles both heat supply and electricity generation, making overall high energy efficiency possible. Also, the supply of timber for fuel is being co-produced with the local forest industry, starting up a new activity called “local production for local consumption” to make the most of the local specialty.

Of course, the basics of environmental activities such as “compliance to law”, “efficient use of resources” and “improvement of greening ratio” are being consistently pursued as activities to be steadily maintained.

Komatsu will continue to contribute to sustained development while making life richer for people, through products and solutions that have excellent environmental qualities born of advanced technology, and through pursuing revolutionary efficiency at our production sites.
