Global Warming Preventive Measures
The KOKUYO Group strengthens activities to ease global warming (measures for the reduction and absorption of CO2 emissions) with a view to achieve a low carbon society.
Summary for 2020
In 2020, a total of 22,334 tons of CO2 was emitted by our consolidated subsidiaries in Japan1 and by our disability-friendly subsidiaries, KOKUYO K Heart and Heartland. This total represents a reduction of 4,085 tons (15.5%) from the previous year, which exceeds our carbon reduction target. The change in emission coefficients2 accounts for 715 tons of the reduction. According to our estimates, the actual reduction was 3,370 tons and the breakdown was as follows: We cut 428 tons by improving operations, 179 tons by improving facilities and equipment, and 2,763 tons by consolidating manufacturing operations. The reductions for offices, production sites, and distribution channels are as follows.
Our offices reduced their emissions by 859 tons from the previous year’s level (765 tons if the exhaust coefficient is excluded).
The breakdown was as follows: 683 tons of emissions were cut as a result of office responses to the coronavirus pandemic such as allowing remote work and more flexible working hours. Besides this, 82 tons were cut by using less air conditioning, by existing efforts to promote more efficient working patterns (such as instituting a no-overtime day and encouraging workers to leave work on time), and by installing energy-efficient LED lighting.
Our production sites reduced their emissions by 2,570 tons from the previous year’s level (2,121 tons if the exhaust coefficient is excluded).
The breakdown was as follows: 1,750 tons of emissions were cut because of pandemic-related production stoppages. Besides this, 320 tons were cut by operational improvements. These included cutting changeover times, tightening compliance with rules for machinery and equipment, improving inspections, making production schedules more precise, and running energy audits to ensure energy efficiency. Additionally, 51 tons were cut by installing inverters and energy-efficient LED lighting.
Our distribution channels reduced their emissions by 656 tons from the previous year’s level (484 tons if the exhaust coefficient is excluded).
The breakdown was as follows: 330 tons of emissions were cut because of shipment holdups caused by the pandemic, 31 tons were cut by ongoing efforts to save energy (operational improvements, lighting adjustments at distribution centers), and 123 tons were cut by installing energy-efficient LED lighting.
*2 As to CO2 emission coefficients for electricity, we adopt the coefficients based on Japan’s Act on Promotion of Global Warming Countermeasures (base emission coefficients for each electricity company based on actual performance for 2018 and 2019).
Total CO2 Emissions by KOKUYO Group
Total emissions for all 31 organizations1 in the corporate group (which includes Iwami Paper Industry since 2018) amounted to 32,299 tons, 2 a reduction of 7,525 tons from the 2019 level. Around 2,500 tons of the reduction was attributable to the energy provider reducing its emissions coefficients. The remaining 5,000 tons was attributable to our ongoing efforts to cut emissions as well as to reduced worker attendance amid the pandemic.

*2 As to CO2 emission coefficients for electricity in Japan, we adopt the coefficients based on the Act on Promotion of Global Warming Countermeasures (base emission coefficients for each electricity company based on actual performance for 2018 and 2019). As to CO2 emission coefficients for overseas electricity, we adopt the CO2 Emissions from Fuel Combustion 2019 edition by the International Energy Agency.
The difference due to change in coefficients is the difference with the emissions calculated based on the average of all electricity sources for 2000 (0.378 kg-CO2/kWh).

Improving the Accuracy of Scope 3 Data
Thanks in part to the work of the Carbon Disclosure Project (CDP), there is growing interest in carbon reporting. Businesses around the world are increasingly expected to disclose information on their scope 3 emissions. Scope 3 emissions are indirect emissions throughout the value chain, including in production, shipment, consumption, and disposal.
Before 2014, we were already disclosing some scope 3 emissions (such as emissions produced during shipment). Since 2014, we have disclosed scope 3 emissions in accordance with the Ministry of the Environment’s Basic Guidelines on Calculating Volumes of Greenhouse Gas (GHG) Emissions.
In 2020, our value chain produced a total of 543,478 tons of GHG emissions. Scope 3 emissions accounted for approximately 94% of this total. As much as 83% of the scope 3 emissions were from purchased goods and services (Category 1).
The reliability of our environmental data was confirmed in an independent assessment conducted Bureau Veritas Japan.
