Based on its material CSR issues (materiality), the Nabtesco Group has been promoting Group-wide efforts to reduce greenhouse gas emissions and to enforce energy-saving activities as part of its measures against climate change. In FY2012, we introduced the energy conservation activity commendation program to further strengthen our energy-saving activities. We have set Group-wide improvement themes, including the reduction of energy consumption in equipment operations, maintenance and management and other production activities, and strive to steadily reduce greenhouse gas emissions by monitoring the status and effects of such efforts in a quantitative manner. In addition, we have introduced an energy-saving product certification system to promote the development of energy-saving products, thereby contributing to reducing greenhouse gas emissions generated by our customers’ use of our products.
In November 2016, the Paris Agreement*1, an international framework for countermeasures against climate change beyond 2020, came into effect and the 2 degrees Celsius target*2 was adopted as an international target. In response, the Nabtesco Group set a long-term target for reducing greenhouse gas emissions, which has been approved by the SBT (Science Based Targets)*3 Initiative.
The Nabtesco Group also advocates the measures taken by the CDP*4of the United Kingdom to mitigate the impact of climate change and reduce greenhouse gas emissions. In FY2010, we began to disclose the Nabtesco Group’s climate change strategies and greenhouse gas emissions to the CDP to enhance the transparency of our own efforts. In FY2018, Nabtesco Corporation was selected for inclusion in the Climate A List, the highest rating from the CDP, and was selected as one of the CDP's Supplier Engagement leaders. In addition, we will also start to support the Task Force on Climate-related Financial Disclosures (TCFD)*5reported in 2017 to the Financial Stability Board (FSB)*6
Furthermore, the Nabtesco Group has been participating in various activities with organizations related to environmental conservation including the study group on environmental management in the United Nations Global Compact Network Japan. Through our collaboration and dialogue with these initiatives, we are actively advancing our activities to meet the challenges of climate change and we will continue to strive to take related action.
In FY2016, the Nabtesco Group set long-term greenhouse gas emissions targets for FY2050 with the aim of preventing global warming. Specifically, we aim to reduce (1) CO2 emissions by our Group companies in Japan and (2) CO2 emissions relative to sales (per unit of sales) from our global production activities including emissions from our overseas sites, by 30% in FY2030 and by 80% in FY2050 compared to the FY2015 levels. Moreover, the long-term target for reducing greenhouse gas emissions from Nabtesco Corporation, which is included in (1) above, has been approved by the SBT Initiative.
We have also set medium-term targets for FY2020. Specifically, we aim to reduce our total amount of CO2 emissions to a level below that of FY2015 and lower our emissions per unit of (global) sales by 9% or more, in light of the anticipated increase in production volumes and reinforcement of plants and equipment in line with our expected future operational growth.
|CO2 emissions target||FY2015
|Total CO2 emissions [In Japan]||46,100||46,100||32,270||9,220|
|Per unit of sales [Global]||0.239||0.217||0.167||0.048|
In addition to reducing our own emissions, we have begun to expand activities to our suppliers. Of the greenhouse gas emissions from our entire supply chain, the percentage of emissions from purchased goods and services (category 1 of Scope 3 emissions) is high, making it essential for our suppliers to take initiatives to reduce their greenhouse gas emissions. In response, we began a survey of our main suppliers (top suppliers who constitute 70% of the annual amount of purchases) to see whether they have set voluntary targets to reduce their greenhouse gas emissions. As of FY2018, 51.3% of our main suppliers have set voluntary targets to reduce their greenhouse gas emissions and begun to take initiatives to achieve the targets. We will provide support so that all of our main suppliers will set voluntary reduction targets by 2025.

Scope 3 Emissions
Due to the increased production volume and transient increase in emissions caused by moving to the newly built building (one building) at our Gifu plant (Gifu Prefecture), our domestic CO2 emissions exceeded the target significantly in FY2018.
The following shows our main energy-saving activities in FY2018. We utilized cutting-edge environmental technology at our Gifu plant, achieving a 50% reduction in conventional CO2 emissions for the completion of a new building. In addition, to further improve energy efficiency, we renovated processing facilities by using inverters and replaced air conditioning facilities and lighting equipment with high-efficiency models.
While our global emissions from both domestic and overseas sites remained mostly unchanged, the CO2 emissions relative to sales from our global production activities exceeded the target by 5%.
The Nabtesco Group has been engaging in energy-saving activities by improving the efficiency of production and air conditioning facilities and by making use of energy monitoring systems, with the aim of achieving our long-term targets. Although our production capacity is expected to continue to expand in line with operational growth in the future, it is a prerequisite that new plants to be established in Japan and overseas cut their energy consumption by 40% or more relative to that of existing plants. It is our plan to leverage energy-saving technologies to be developed at these new plants for use at our existing plants, thus achieving the reduction of CO2 emissions across the Group.
|Item||FY2018 Targets||FY2018 Results||Performance||Status|

The Nabtesco Group began to calculate greenhouse gas emissions from the entire supply chain in FY2013 with a view to identifying and effectively reducing the environmental impact of our business activities as a whole. The following table shows the calculation results of past three years.
|Direct emissions (Scope 1)*7 *8||7,259||8,686||8,781|
|Indirect emissions through the use of electricity and others (Scope 2)*7 *8||50,865||61,538||61,395|
|Emissions from the supply chain (Scope 3)*9||885,494||871,463||979,097|
The following table shows the breakdown of our Scope 3 CO2 emissions. Of our Scope 3 CO2 emissions, “Purchased goods and services” (category 1) accounts for the largest percentage of 75.9%, followed by “Upstream transportation and distribution” (category 4) at 17.4%.
At the Nabtesco Group, we will continue to identify and reduce greenhouse gas emissions from our entire supply chain.
In order to ensure the reliability of the calculation results, we had them verified by a third party, Lloyd’s Register Quality Assurance Limited.

The Scope 3 calculations for FY2018 were made by the following method and for the following period and scope.
The Nabtesco Group strives to reduce its energy consumption. We are continuously working to conserve energy and replace existing equipment with energy-saving alternatives. We have also installed electricity meters in our energy-heavy production facilities to monitor excessive use of electricity and standby power, repair equipment, and improve operational methods.
We have also visualized our energy consumption by introducing a monitoring system, which permits us to monitor our energy consumption on a real-time basis.
To raise awareness of energy conservation, we established the energy conservation activity commendation program in September 2012. In FY2018, Nabtesco Automotive Corporation, Nabtesco Power Control Company, Toyo Jidoki Co., Ltd., and Nabtesco Marine Control Systems Company received awards in this commendation program.
The Nabtesco Group is promoting the use of renewable energy equipment at its facilities. First introduced to the Tarui Plant (Japan) in 2012, solar power generation facilities began operating at the Tsu Plant (Mie Prefecture) and the Kobe Plant (Hyogo Prefecture) in 2016, at the Gifu Plant and a precision reduction gear plant of a Group company in China in 2017, and Toyo Jidoki Co., Ltd. (Yamaguchi Prefecture) and Nabtesco Service Co., ltd. (Kanagawa Prefecture) in 2018.
The Nabtesco Group will continue its proactive measures to promote the use of renewable energy in the future.
Nabtesco’s eco label and Certificate
This certification system was established to foster the design and the development of energy-saving products in order to promote environmental protection and the development of a sustainable society. Through this system we are contributing to the mitigation of global warming while increasing the environmental awareness of our employees.
For products that have obtained the certification, we issue certificates, approve the use of the certification mark and make announcements about the certification in our in-house magazine. For energy-saving product certifications, we internally evaluate products to be released on the market to see whether they meet more than one certification criteria and exceed existing levels in non-requisite criteria items.
In FY2018, we certified the following product manufactured by Toyo Jidoki Co., Ltd. This DDS3 interlocking-type track filling attachment unit reduces the installation space required by 50% compared to the previous models and increases the production capacity. The Nabtesco Group will continue to make its best efforts to contribute to solving climate change by further developing its motion control technology for moving precisely and stopping objects.

The Nabtesco Group collects important information about the environment, safety, accident prevention, health, and others, including climate change-related risks and opportunities, assesses the materiality of related issues, and discusses measures to implement for those that are deemed to be important.
In FY2018, to diminish the risks of climate change, we implemented some measures, for example we replaced air conditioning facilities with the models that are expected to increase energy efficiency as the rising average temperature accelerates their use, and repaired some damage caused by typhoons. The expenses for these activities were approximately 123 million yen.
Furthermore, in FY2018 we spent about 10.2 billion yen on R&D related to climate change measures, development of green products, and other initiatives.
The Nabtesco Group owns motion control technologies, which are used to control movements of a variety of equipment, including precision reduction gears for industrial robots, travel unit for excavators, aircraft flight control actuation systems, brake operating units and door operators for railroad vehicle, engine control systems for marine vessels, and automatic doors for buildings and other structures. Based on these technologies, we will pursue higher energy efficiency in a range of business fields and thereby contribute to reducing greenhouse gas emissions generated through use of the above equipment by our customers.
