Reducing CO2 Emissions in Manufacturing Operations

Independent Practitioner's Assurancecheckmark

As a part of our efforts to mitigate climate change, Komatsu set mid and long term objectives in Japan and overseas operations for the amount of electricity, fuel gas, fuel oil, and other types of energy used in manufacturing operations, using CO2 emissions per unit of manufacturing value as the indicator, to proactively reduce the amount of CO2 emissions units.
In 2010, in response to the climate change issues raised in the Post-Kyoto Protocol, we set a mid-term objective that by 2015 we would reduce CO2 emission levels by 40% compared to the levels in 1990. Since then however, using the "cutting electricity use in half" activities that followed the Great East Japan Earthquake as an impetus, we set an ambitious goal of a 54% reduction compared to FY2000 levels and pursued activities to reduce power consumption and achieved great outcomes. As a result, in February 2017, we received the "Kanto Bureau of Economy, Trade and Industry Director's Award" as an energy management superior business operator. From FY2016, we have set new mid- and long-term objectives for both domestic and overseas operations, and are moving forward with further improvement activities.
In FY2016, as a result of energy-saving activities undertaken based on the lateral spread of various production reforms, the CO2 emissions per unit of manufacturing value was reduced by 41.0% compared to FY2000 levels. However, due to an increase in electricity use for the summer/winter air conditioning and the fuel to test components, the index was worse than the previous year. The ratio of renewable energy for in-house power generation was 19.2%, due to the cutback in in-house power generation using fossil fuels, an increase of 1.4 times the previous year.
CO2 emission at Komatsu's overseas manufacturing sites have also been reduced by 28.7% compared to FY2010 as a result of fuel conversion and lateral spread of improvement examples from Japanese plants.
For FY2017, aiming for the achievement of mid-term objectives, we will work towards further reduction in CO2 emissions index numbers by updating buildings that are over 40 years old to building that incorporate the newest energy-conserving technology, and by making small but steady improvements on job sites.

Certified as a "Climate A List" Company by CDP

In October 2016, Komatsu was certified as a "Climate A List" company by CDP, an international NGO that works on making a sustainable economy a reality. A "Climate A List" title is given to a company that has been recognized as a world leader in its response and strategy for mitigating climate change. Responses to the questionnaire sent by CDP, representing 827 corporate investors with a total sum of US$100 trillion in invested assets, was evaluated by a unique methodology established by CDP. 193 companies considered to be especially outstanding in their emissions reduction activities and climate change mitigation measures in the reporting year were certified to be on the A list.
Even before this, Komatsu has placed "environmental activities as one of the top priority issues of management", and as part of our mid-term management plan "Together We Innovate GEMBA Worldwide —Growth Toward Our 100th Anniversary (2021) and Beyond—"which started in April 2016, we have been aggressively implementing actions in initiatives for ESG (E: Environment, S: Society, G: Governance) as a priority focus.
