Measures against Climate Change


The fight against climate change is a crucial global issue that requires the further involvement of each and every person and organization.
The JAE Group in Japan is working to address climate change through environmental awareness training, production–related measures, and measures at plant facilities.
Amount of Carbon dioxide Emitted by the JAE Group in Japan
Total carbon dioxide (CO2) emissions of the JAE Group in Japan in fiscal 2019 were 74,960 tons, an increase from fiscal 2018, and also emissions per unit of sales increased.The main cause was the effect of production volume. We will continue to further promote energy saving in infrastructure and production equipment, and to carry out efficient production while monitoring total CO2 emissions and emissions per unit of sales.

※Energy usage per sales unit 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 2019, the fiscal 2018 result (0.463 ton-CO2/MWh) is being used.
Status of progress toward uniform goals in the electrical and electronics industries
The JAE Group in Japan participates in the electrical and electronics industries’ Action Plan for Achieving a Low Carbon Society and is progressing toward the goal of a 1% annual average energy efficiency improvement in production processes through 2030.Although total energy usage is increasing in line with higher production volumes, we have curbed energy usage per unit by taking steps to contribute to the fight against climate change.
In fiscal 2019, the improvement rate was 27.57% on a per-unit of energy basis, surpassing the goal of 6.79%.
Status of Response to Tokyo Cap-and-Trade Program
The Akishima Plant has an obligation to cut greenhouse gas emissions by an annual average of 15% during the second phase of the plan from fiscal 2015 to fiscal 2019.Emissions in fiscal 2019 were down 13.9% from the baseline emissions and our 15% annual reduction target was not achieved, but a 17.4% reduction was achieved in the second phase of the plan.
The Akishima Plant has an obligation to reduce emissions by 25% in the third phase of the plan from fiscal 2020 to 2024. As it is, achieving the reduction obligation will be difficult, so we will make further efforts to fight global warming by introducing renewable energy and other measures.

Fiscal 2019 Energy Conservation Case Studies
1. Plant facilities
Implemented content (1) | ||
Reduction of loss by replacing substation transformer (JAE) | We adopted a highly efficient amorphous transformer. ・Replaced the substation transformers of office buildings. ・Simultaneously integrated transformers (6 units→4 units) and re-examined capacity. ・Replaced 1 substation transformer at No. 2 Plant |
|

Result | Status |
27,966 kWh/year (office building) 11,009 kWh/year (No. 2 Plant) |
Need to replace substation transformer. (Every 30-35 years) Performed scheduled replacement of high-efficiency equipment from fiscal 2012. (Replaced 8 units up to fiscal 2018) A more efficient amorphous transformer was adopted from 2019. We plan to replace one high-voltage power receiving station, three substations at No. 3 Plant, thirteen substations at No. 1 Plant, and two substations at the gymnasium with high-efficiency transformers by 2025. |
Implemented content (2) | ||
Integrated cooling water pump for use in production at No. 1 Plant (JAE) | 2In fiscal 2017, we achieved energy saving by installing a bypass pipe for the two cooling water pumps used in production that had operated individually, and integrated them into one unit, and removed the other unit from service. | |
Subsequently, pump capacity was inadequate due to an increase in equipment that uses cooling water, so the cooling water pump was replaced in fiscal 2019 with an inverter type cooling water pump unit, loads were integrated, and two units were shut down. Further energy saving was achieved by inhibiting the output so that cooling water pressure is constant according to the load. | ||

Results of fiscal 2019;
Reduction of 35.92 ton-CO2.
Activities to Increase Awareness of Measures to Fight Climate Change
Introduced here are several fiscal 2019 efforts made to increase awareness of climate change measures.- No Driving Day
- Eco-driving training
- Clean up campaign around each work site, and other activities
(For details, see the Environmental Education section[click to open])
- Cool Biz (May 7 through October 31)
- Warm Biz (November 1 through March 31)
July 7: “Tanabata Lights Down” (Cool Earth Day)
Measures to fight climate change through supply chain cooperation
The JAE Group asks its domestic suppliers to agree to and implement greenhouse gas emission reductions in line with its CSR guidelines, and it aggregates the annual of energy purchases of each company. The top 20 companies that the Group transacts business with (excluding trading companies) have slightly decreased the amount of power they purchased since fiscal 2018.Building a sustainable world
