Climate Change Initiatives

The TOKYO KEIKI Group strongly recognizes the impact and risk posed by climate change to the group’s businesses and all of our stakeholders as important business issues. In order to fulfill our responsibility as a company to mitigate climate change, we are promoting initiatives to reduce greenhouse gas (GHG) emissions from each of our divisions. As part of this, we announced our endorsement of the Task Force on Climate-related Financial Disclosures (TCFD) recommendations in August 2022 and have started an initiative aligned with the recommendations’ framework of governance, risk management, strategy, and metrics and targets. Through this initiative, we will strive to enhance our climate change-related information disclosure and will also be working to further increase the Group’s resilience.

The Group established a new environmental target for FY 2030 to reduce Scope 1 and 2 GHG emissions by 37% in comparison with FY 2013. However, due to a recovery in orders, which had declined because of the impact of COVID-19, facility operating hours increased. As a result of this and other factors, our emissions were 10,019 t-CO2, a 2.9% increase in comparison with the previous fiscal year. Going forward, we will accelerate reduction of our GHG emissions, promoting not only routine energy-saving initiatives, but also the introduction of renewable energy facilities and the procurement of renewable power.

Energy consumption and GHG emissions (Scope 1, 2)

Electricity use


More efficient energy use to reduce GHG emissions

We are working to make efficient use of energy. Our efforts include implementing energy-saving measures at our facilities, such as switching to new energy-saving air conditioners, highefficiency power reception facilities, and inverter compressors; increasing transformer energy conservation; and using heat shield paint on roofs and exterior walls. We are also engaging in activities to conserve energy, including power demandbased power monitoring, and proactively turning off lights. Other measures we are taking include curbing the occurrence of defects in the design stage, and engaging in continuous improvement of production processes.

Conclusion of power purchase agreement for solar power

TOKYO KEIKI PRECISION TECHNOLOGY (TPT), which produces hydraulic equipment for Asia in Vietnam, made the decision to switch approximately 30% of the power used in its factory to solar power as an initiative to reduce GHG emissions and concluded a power purchase agreement (PPA) for solar power in March 2022. With this agreement, TPT expects to reduce its GHG emissions by approximately 400 tons annually. This initiative is a first for our Group, and we will be considering similar arrangements for other production sites.

Heat shield paint applied to the roof of Sano Plant
Due to climate change, in recent years, severe rainfall occurs frequently in the Sano Plant area. Because of the increased risk of such damage as roof leaks resulting from the sudden increase in rainfall, we, at Sano Plant, conducted maintenance and repainted on the plant’s entire roof. As a result of using a heat shield paint, which reflects infrared rays to control an increase in the temperature of the roof, we confirmed an energy conservation effect by reducing the load on air conditioning equipment during the summer months.



Calculating Scope 3 greenhouse gas emissions
In order to understand supply chain GHG emissions across all of our business activities and effectively reduce them, we calculated the total emissions of all of our supply chains. The table to the right provides a breakdown of our Scope 3 emissions (indirect emissions other than a company’s own from its supply chain). Emissions from purchased goods and services (category 1) were the greatest at 49.6% of the total, followed by use of sold products (category 11) at 38.4%. Going forward, we will continue to maintain an awareness of, and promote reductions of, GHG emissions across all of our supply chains.

Overview of Scope 3 CO2 emissions calculation (FY2021)
*1: Not applicable (emissions from leased assets included in Scope 1 and 2).
*2: Not applicable (finished product logistics outsourced and thus included in category 4).
*3: Not applicable (as TOKYO KEIKI’s products are finished products, they are not processed after sale).
*4: Not applicable (no relevant leased assets).
*5: Not applicable (no relevant franchises).
*6: Not applicable (no relevant investments).

Calculation method: Based on standard guidelines from the Ministry of the Environment and the Ministry of Economy, Trade and Industry concerning the calculation of greenhouse gas emissions from supply chains.
Calculation period: April 1, 2021–March 31, 2022
Calculation scope: TOKYO KEIKI (non-consolidated)

MIRAI, a fuel cell vehicle, selected for President’s vehicle
MIRAI is a fuel cell vehicle (FCV) from Toyota that runs on hydrogen fuel and emits zero GHGs. The Group’s TOKYO KEIKI Vision 2030 identifies hydrogen and other energy businesses as candidates for new growth drivers. Based on this, the MIRAI was selected when updating the President’s vehicle.
