Initiatives to Reduce our Environmental Burden

CO₂ Emission Reduction Targets

In December 2021, Amano formulated CO₂ emission reduction targets to help reduce greenhouse gas emissions.
To prevent global warming, we will continue efforts to reduce CO₂ emissions.

CO₂ emission reduction targets: a 46% reduction in FY2030 compared with levels in FY2013.

＊ Note: These targets concern Scope 1 and 2 corporate emissions.

Energy Saving Initiatives

In order to reduce CO₂ emissions, Amano is promoting energy-saving activities at each business site. As reducing electricity and gasoline consumption is the most effective way to reduce energy consumption, to achieve this, each business site is making continuous efforts by sharing and applying ideas.
Energy reduction measures that are common among the sites are as follows:

Appropriate air-conditioner temperature settings (implementation of Cool Biz and Warm Biz)
LED lighting and power saving
Turning off unnecessary computers
Energy saving and optimization measures for production equipment and air conditioning equipment
Reducing power consumption and number of units by adopting energy-saving multifunctional copiers
Reducing standby power consumption during long vacations
Promoting the conversion of high power consumption equipment to energy-saving models using the electric power visualization system
Promoting company-wide eco-driving
Proceeding with the switch to eco-cars

Shifting to self-consumption solar power generation (Sagamihara Factory)

Replacing laser beam machines with highefficiency machines (Hosoe Factory)

Replaced aging transformers to improve the efficiency of power supply (Hosoe Factory)

Upgraded to energy-efficient screen printers (Sagamihara Factory)

Upgraded to energy-efficient injection molding machines (Sagamihara Factory)

Water Reduction Target

Water is an indispensable resource in manufacturing activities. As such, we are setting goals to reduce environmental impact, avoid risks, and achieve sustainable water use in order to use limited water resources efficiently and appropriately.

Water reduction target : Reduce water usage by 1% compared to the previous year.

＊ Note: Targets are Head Office, Sagamihara Factory, and Hosoe Factory sites.

The amount of water used in FY2024 increased 8.3% year on year. This increase was due to the impact of sprinkling water to control dust during factory demolition and washing work that accompanies roof and outer-wall painting. In addition, additional painting operation time in part manufacturing processes also increased the amount of water used.

Criteria for Water

At the Hosoe Factory, we regularly measure the water quality of wastewater and manage it so that it does not discharge outside the factory, and there are no items that do not meet the current emission standards.

Item		Drainage reference value (mg/l)	Voluntary reference value (mg/l)	FY2024

(＊)Drainage outlet 3 is excluded from measurement since it is used for septic tank drainage.

Reducing the Consumption of Copy Paper

The three sites (Head Office, Sagamihara Factory, and Hosoe Factory) are continuing their efforts to reduce the amount of copy paper used, such as by promoting double-sided printing, paperless meetings using notebook PCs with large display screens, and the computerization of inspection sheets, etc. As a result of these efforts, the amount of paper used in FY2024 was reduced by 4.9% compared to the previous fiscal year. We will continue to promote these initiatives.

Battery Recycling

As part of initiatives to contribute to the creation of a recycling-oriented society, since December 2012, we have been extracting all depleted batteries from cleaning products and recycling them. In FY2024, 86.5 tons (2,880 batteries) were recycled.The number of items recycled is decreasing because the design of the HAPiiBOT robotic floor scrubber was changed to use lithium-ion batteries.
