Measures against Climate Change

Amount of CO2 Emitted by the JAE Group

*Energy usage per sales unit (*use the cursor to view definition) is shown as unit of CO₂ emissions in Japan and overseas, and consolidated net sales (unit: t-CO₂/100 million yen)

※The equivalency factor for CO₂ emissions due to energy use is the value published by the Federation of Electric Power Companies. In fiscal 2021, the fiscal 2020 result (0.441 ton-CO₂/MWh) is being used.

To reduce future CO₂ emissions, JAE will work to achieve the following targets (CO₂ emissions from Scope 1 and 2 production sites in Japan and overseas), looking to achieve net-zero CO₂ emissions by 2050, in accordance with the government’s policy. 

In addition, we will continue to monitor our electricity consumption, total CO₂ emissions, and emissions per sales primary unit, while further promoting energy savings in infrastructure and production equipment and carrying out efficient production.

Status of Response to Tokyo Cap-and-Trade Program

Contribution of the JAE Group Forest

The Group has estimated that the amount of greenhouse gases (CO₂) absorbed through the planting of Japanese cypress and broadleaf trees in the JAE Group Forest is about 5.3 tons-CO₂ per year.

Fiscal 2021 Energy Conservation Case Studies

Plants and related facilities

Implementation details (1)
Maintenance of power and air conditioning monitoring systems (JAE)	The power and air conditioning monitoring systems installed in 2003 were upgraded due to deterioration. Along with the upgrade, measurement locations were established and reinforced (electric power was expanded from 192 to 268 points, and 10 air flow points were added), and software was customized. As a result, we can now monitor the detailed usage status of each department and every major process and use that information to confirm the effectiveness of energy conservation activities and identify issues needing improvement.

Implementation details (2)
Reduction of power consumption through vacuum pump replacement (HAE)	In the past, factory air was used for the suction of workpieces into automated assembly machines, but rotary vacuum pumps were installed because having a vacuum pump for each machine would reduce power consumption. Furthermore, power consumption was reduced by replacing them with rocking piston vacuum pumps, which have a lower power rating.
	Effect	Notes
	477,401.2 kWh/year	―

Lighting

Implementation details (1)
Switched to LED lighting (JAE)	Replaced 234 ceiling lights on the third floor of Factory No. 1. Replaced 129 ceiling lights on the fourth floor of the office building. Replaced 124 ceiling lights on the sixth floor of the office building. Replaced 6 ceiling lights with movement sensors in the 5th floor locker room of the office building.
	Effect	Notes
	42,809 kWh/year	Lights in buildings have been systematically changed to LED lighting since fiscal 2013. We plan to systematically update lighting in the office building and No. 1 factory floors that have become outdated. As of the end of fiscal 2021 2,945 LED lights out of 10,245 lights Progress rate: 29%

Activities of overseas production bases

Implementation details (1)
Energy conservation activities (JAE-WX) Compressor frequency conversion cabinet added Installed and began operating frequency conversion pump Improved lighting in common areas	Improved savings on electricity The existing cooling system had some power wastage due to its use of industrial frequency pumps. Power consumption was reduced, and savings achieved by changing to frequency conversion pumps. We saved power by attaching an additional frequency conversion cabinet to a compressor with a high unload rate and power wastage to reduce the compressor unload rate. We culled 300 lamps in common areas to the extent that lighting intensity was unaffected.
	Effect	Notes
	Reduction of about 271,000 RMB per year	ー

Logistics related

1) CO₂ reductions from modal shift (railway transport)

Reduced CO₂ emissions by switching from truck transport (crates) to railway transport (containers) 
CO₂ emissions were reduced by 3.4827 tons (compared to truck transport)

2) CO₂ emissions reductions by using reusable trays

CO₂ emissions were reduced by reusing trays for connectors.
CO₂ emissions reductions = 67.3149 tons
*26.398 tons of reusable trays/year x conversion factor of 2.55 CO₂/tons = 67.3149 tons
