Environmental Data

The amount of greenhouse gas emissions from all our sites in Japan is converted to a CO2 equivalent weight as shown below.

The above greenhouse gas emissions amount (t-CO2) is calculated by taking the total of the WRI/WBCSD GHG Protocol Scope 1 and Scope 2 emission amounts.

[Conversion factor]
Purchased electricity: Uses each electric company's conversion factor for the Act on the Rational Use of Energy report
Liquefied petroleum gas: 6.527 tons of CO2/1,000㎥, town gas: 2.05 tons of CO2/1,000 ㎥,
heat: 0.0468 tons of CO2/GJ, gasoline: 2.29 tons of CO2/kL,
light oil: 2.62 tons of CO2/kL, kerosene: 2.5 tons of CO2/kL

The total amount of waste generated at our business sites is as follows. We promote effective utilization through heat recovery, recycling, and other means at all office and factory sites.

We set a goal for 5% or more reduction in the amount of waste, down to 527 tons or less from the 555 ton average of fiscal years 2012 to 2014.

Although the amount of waste generated increased compared with fiscal 2024 due to the return of the east side of the 9th floor at Yokohama Headquarters, the relocation of PFU Quality Service Limited’s headquarters, and the disposal of unnecessary items associated with support for large-scale business negotiations, the fiscal 2025 result was 406 tons, a reduction of 27%, achieving the target.

At each site, we use tap water for domestic use and to humidify the office in winter. At our Headquarters, we use ground water to water our plants in summer, and at our Headquarters and the ProDeS Center, we use ground water to melt snow. We use water for our every day needs at our company sites, not for industrial purposes.

For our total water consumption amount, we set a target to reduce it by 1% or more to an amount of 35,600㎥ or less compared to the reference year of 2018.

In fiscal 2025, due to heavy snowfall, the use of groundwater for snow melting increased. As a result, water consumption was 44,000 m³, an increase of 23%, and the target was not achieved.

Our water is used for everyday purposes. We do not have any water that can be reused or recycled.

Tap water used for domestic uses drains into the sewer. Ground water used to melt snow drains into the rivers, and water used to water plants drains underground. We have been continuously monitoring and measuring water quality by using our own self management values in order to ensure the quality of water that drains from our main sites.

In fiscal 2025, heavy snowfall led to an increase in groundwater use for snow melting, resulting in an increase in the amount of water discharged into rivers.
