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 2018 were 72,075 tons, down year on year, but 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.
| CO2 emissions volume by energy usage |
※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 2018, the fiscal 2017 result (0.496 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 2018, the improvement rate was 27.22% on a per-unit of energy basis, surpassing the goal of 5.85%.
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 2018 were down 20.7% from the baseline year and we achieved our 15% annual reduction target. We expect to achieve our obligation to reduce greenhouse gases during the second phase of the plan.
We will keep working to do our part in the fight against climate change.
