AOTS Environmental Activities
I. Environmental Policy
1. AOTS Environmental Philosophy
|
In order to be “an environmental-friendly specialized training organization”,
AOTS is actively committed to the reduction of the 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.
At the 8th AOTS Alumni Convention which was held in Yokohama in October 2009,
AOTS environmental policy was endorsed and supported by AOTS Alumni Associations.
Particularly this summer, with the electricity shortage resulting from the March 11 earthquake,
the issue of energy-saving is a concern throughout Japan, we at AOTS have committed to
energy-saving and environmental conservation activities. |
2. 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 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. |
| 5) |
We actively conduct training in the environmentally related fields to transfer excellent
Japanese environmental technologies to the participants who are invited from all over the world and enhance
their awareness and knowledge about environmental issues. |
II. Performance in Environmental Impact Reduction
Reduction of CO2 Emission (compared to FY 1999)
-25% (Compared to FY1999)
-6.5% (Compared to FY1999)
| 1) |
Compared to the 1999 value,
reduction of CO2 emissions can be achieved smoothly.
However, because of last year's extremely hot summer,
both total CO2 emissions and CO2 per guest per day
show a modest increase as compared with FY2009. |
| 2) |
Total CO2 emissions have been reduced by
1096.1
tons compared to the 1999 value. This CO2 reduction value is almost the same as
the annual amount of CO2 assimilated by about
140
ha plantation of 80 year-old cedars (approx.
77
thousand of cedars/
29.9
times as large as Tokyo Dome).
[which is also almost the same as the annual amount of CO2 absorbed by
about
238
ha natural forest, mainly of 80 year-old beech
(50.9 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). |

III. AOTS Main Environmental Activities
| 1) |
Energy efficiency can be enhanced by using the exhaust heat generated during
in-house power generation by a cogeneration system.[Tokyo, Osaka & Chubu] |
Mechanism of Cogeneration
|
| 2) |
Installation of an Inverter Control System to our air conditioning system (FY2009)
Energy efficiency can be enhanced by reducing the number of revolutions of air-conditioner
and exhauster motors according to the situation. [Tokyo]
|
| 3) |
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 |
|
|
| 4) |
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 May. to Oct.)
|
|
| 5) |
Removal of unnecessary lighting and enthusiastic adoption of
human detection sensors (in bathrooms, etc.)
Partial adoption of energy saving lighting (energy-saving, long life type/ LED type)
Control of power supply for guest rooms on key-tag by key-tag basis
Reduction of useless energy consumption for non-occupied rooms, etc.
|
| 6) |
Purchase of low environmental impact products
- Selection and purchase of “Energy Star” products
when buying computers
- Guest room television sets being replaced with products that
Meet energy saving standards (for all rooms), etc.
- Replacement of desktop PCs with thin-client terminals can reduce
the electricity consumption by up to 90%. In addition,
the reduction of the heat discharge from the thin-client terminal reduces
the ambient temperature, having the knocking-on effect of reducing
the need to use air-conditioners.
It also assists in energy reduction by consolidating the server system

| 7) |
Participation in the “Challenge 25 %” program
|
| 8) |
Recovery of PET bottle caps (eco-cap activities)
