Global Warming Preventive Measures

We are developing an environmental management system with the goal of becoming an Asian company. In order to reduce the amount of greenhouse gases significantly with a view to achieve a low-carbon society, we have expanded the scope of our reporting targets.

Summary for 2017

If calculated for the existing scope of operations using the electricity emissions factor of 0.378 kg-CO2/kWh (which is the overall power average in 2000 as reported by the Federation of Electric Power Companies), the KOKUYO Group's CO2 emissions in 2017 totaled 25,979 tons, 637 tons (2.5%) more than in the previous year. Based on estimates, there were emission reductions of 440 tons due to operational improvements and 320 tons due to equipment improvements. Manufacturing operations and the closing and consolidating of facilities raised emissions by 1,390 tons. As a result, there was an effective reduction in CO2 emissions of 760 tons from a combination of operational and equipment improvements. Consequently, excluding the impact of production activities, emissions were down 2.4% from the previous year, allowing us to meet our goal of a 1.4% reduction.

Looking at sources of CO2 emissions, there was an increase of 1,320 tons at factories due to an increase in production. However, as there was a decrease of 550 tons due to higher manufacturing efficiency and other improvements, factories recorded a net increase in emissions of about 770 tons. For distribution activities as well, emissions decreased by 25 tons because of measures such as the consolidation of distribution centers. There was also a reduction of 60 tons due to heightened electricity and energy conservation measures, resulting in a net decrease in emissions of 85 tons. In offices, emissions were down approximately 40 tons as a result of the more efficient use of heating and cooling systems and the effective use of heat storage. Additionally, to use energy more efficiently, we oversee unit energy consumption, which is obtained by dividing energy consumption by sales. In 2017, our unit energy consumption was 0.2% less than in the previous year

If the 2012 emission coefficients for each of the various countries on the greenhouse gas (GHG) protocol website made public by the World Business Council for Sustainable Development (WBCSD) and the World Resource Institute (WRI) are adopted as the figures for the CO2 emission coefficients and added to the Japanese CO2 emission coefficients based on the Act Concerning the Promotion of Global Warming Countermeasures (for 2017, actual emission coefficients for each electricity company for 2015 and 2016), then the total will rise by 6,598 tons to 32,577 tons.

Scope of Reporting

While 16 companies were included in the scope of CO2 emission reporting (reporting scope A *1) until 2011, all consolidated subsidiaries came to be included in the scope of reporting starting in 2012 (for 2017, 31 companies; reporting scope B *2). As a result, CO2 emissions totaled 43,112 tons (including 1,491 tons at non-consolidated sales companies). The changes to the emission coefficient and the extension of CO2 emission reporting to the supply chain have resulted in significant changes for the KOKUYO Group. Consequently, we believe that the medium-term goals for emissions will have to be re-examined.

Measures Implemented in Offices to Help Mitigate Global Warming

Offices lowered CO2 emissions by 40 tons over the previous year.

Offices lowered CO2 emissions by 80 tons over the previous year. To accomplish this, we conducted a review of the methods by which heating and cooling systems were being operated, a review of working styles, promotion of no-overtime days and activities that encourage employees to go home early, and the reduction of electricity use, such as by replacing lighting fixtures with LEDs. At our Shinagawa office, an electric power visualization system is used to lower electricity use during on-peak hour of daytime through the efficient operation of heating and cooling systems and heat storage tanks. In addition, a program that encourages people to use public transportation for sales activities cut gasoline use by about 8% compared to the previous year, which represents a reduction in CO2 emissions of 30 tons. In 2017, the cool biz and warm biz campaigns were combined into a smart biz campaign that was in effect all year long.

Measures for the Prevention of Global Warming in Our Plants

A reduction of 310 tons in CO2 emissions was achieved at our plants thanks to operational improvements attributed in part to a shortening of the time required to make changes to product types, the thorough application of rules for the operations of production equipment, the conducting of inspections, the elaboration of production schedules, and a reduction of waste made possible through energy checks. In addition, a reduction of 240 tons in CO2 emissions was achieved by embracing energy-saving equipment, including adopting systems that enable the installation of inverters and switching to LED lights.

While an increase in production resulted in an increase in CO2 emissions of 1,320 tons on a year-on-year basis, the net increase was only 770 tons (increase of 530 tons domestically and an increase of 240 tons overseas) resulting from a reduction of 510 tons attributed to the above operational improvements and equipment improvements.

Measures for the Mitigation of Global Warming in Logistics

In the area of logistics (storage and shipping), we reduced CO2 emissions by 85 tons compared to the preceding year. Operational improvements achieved through the promotion of daily energy-conservation activities, along with equipment improvements achieved through the introduction of energy-saving lighting fixtures and a review of optimal luminance for lighting fixtures at distribution centers, reduced emissions by 60 tons.

In operating an automated three-dimensional warehouse, KOKUYO Logitem's Ina Distribution Center adopted an electricity demand meter as part of efforts to reduce peak electricity consumption in response to tight supply-and-demand conditions for electricity. In 2017, emissions were reduced by 25 tons through measures such as site consolidation, resulting in a net decrease of 85 tons when combined with the reduction of 60 tons achieved through operational and equipment improvements.

Ascertaining GHG Emission Volumes for the Entire Supply Chain

Emission volumes by scope

In recent years, a movement to engage in carbon disclosure projects (CDP) and to manage and externally disclose Scope 3 (encompassing production, shipping, business trips, commutation, and other categories) emissions generated through supply chains that indirectly emit GHG has been gaining momentum.

While the KOKUYO Group has also engaged in such actions in certain areas such as shipping, actions started to be taken in 2014 in accordance with the Ministry of the Environment's Basic Guidelines on Calculating Volumes of Greenhouse Gas Emissions.

Generated through Supply Chains. The volume of GHG emissions for the entire supply chain in year 2017 was 371,268 tons of CO2. Scope 3 emissions accounted for approximately 90 per cent of this figure with 70 per cent thereof attributed to "Category 1 purchased products and services". Since data has not yet been fully collected from all cooperating plants, this percentage is expected to rise. Given that there are also problems in other categories, improvements will be made from next term.

Third-party verification services provided by Bureau Veritas Japan have also been secured to ensure the reliability of disclosed information and data.
