AOTS Environmental Activities

Environmental Policy

  • AOTS’s Environmental Philosophy
    In order to be “an environmental-friendly specialized training organization”, AOTS is actively committed to the reduction of environmental impact arising from business operations and to environmental conservation activities. For realizing a sustainable society, all of our personnel with a global view will contribute to environmental conservation.
  • Basic Policies
    1)  We continue to check and understand the energy consumption status and to actively work on environmental activities on an all-staff basis.
    2)  We not only promote the separate collection of garbage and recycling of recyclable resources but also to try to reduce emissions, discharges, and wastes to prevent environmental pollution.
    3)  We offer a comfortable service to our trainees and try to improve the residential/training environment while we continue to work on various environmental activities.
    4)  We strive to ensure that our staff’s disciplined devotion to environmental conservation activities can serve as a model to our trainees from overseas.

Performance in Environmental Impact Reduction

  • Reduction of CO2 Emission (compared to FY 1999)
  FY1999 FY2008 Increase/Decrease
Amount		 Increase/Decrease
Rate
Per Guest Per Day
(t-CO2/person day)		 0.213 0.170 - 0.043 - 20.4 %
Total CO2 Emissions
(t-CO2)		 4387.1 3599.0 - 788.1 - 18.0 %
Change of Occupancy Ratio + 1.9 %
[1]  Despite the percentage of occupied beds (Occupancy Ratio) by 1.9% compared to the 1999 value, reduction of CO2 emissions can be achieved smoothly (in terms of both per one guest per day and total CO2 emissions).
[2]  Total CO2 emissions have been reduced by 788.1 tons compared to the 1999 value. This CO2 reduction value is almost the same as the annual amount of CO2 assimilated by about 101 ha plantation of 80 year-old cedars (approx. 55.6 thousand of cedars/ 21.6 times as large as Tokyo Dome). [which is also almost the same as the annual amount of CO2 absorbed by about 171 ha natural forest, mainly of 80 year-old beech (36.6 times as large as Tokyo Dome) ]( * )
* The calculation was made on the assumption that carbon sink per hectare of 80 year-old cedar plantation is approximately 620 tons (approx. 7.8 tons average per year) and that carbon sink per hectare of a natural forest composed mainly of 80 year-old beech is approximately 370 tons (approx. 4.6 tons average per year).

Our Main Environmental Activities

  • CO2 Emission Reduction Activities
[1]  Energy efficiency can be enhanced by using exhaust heat generated during in-house power generation by a cogeneration system.
[Tokyo, Osaka & Chubu]
Mechanism of Cogeneration System
Mechanism of Cogeneration System
[2]  Air Conditioning System Renovation in YKC (FY 2008) [Yokohama]
A. Transformation of the existing air-conditioning systems (chiller, air-conditioner, etc.) into new high efficiency models
B. Guest room air-conditioners were replaced with single packaged air-conditioners, which helped to reduce not only the power consumption for cold/hot water supply but also the excess energy due to low occupancy ratio
* In consideration of compatibility between the improved accommodation service of the center and improved energy efficiency
[3]  Implementation of Dress Codes "Cool Biz" and "Warm Biz"
A. Air conditioning temperature:
(Office)28°C (cooling period), 20°C (heating period)
B. Encouragement to wear light clothing (From Jun. to Sept.)
[4]  Environmental/energy conservation training workshops for our personnel
