TOPICS
“Eco management” is one of the action areas in Yamaha Motor Group Environmental Plan 2020, and based on this the Group has pursued
global environmental ISO 14001 unified certification, which strengthens the Group’s environmental governance framework and achieves
efficient environmental management operations, at locations in Japan and overseas since April 2012.
This program covers main manufacturing centers representing 39 companies in Japan, Europe, ASEAN, China, Taiwan, India and South
America, and as of the end of 2014 unified certification had been obtained by 26 companies (67%).
The Yamaha Motor Group has also introduced an in-house environmental management certification system for companies that have a
relatively smaller environmental impact, as part of our global environmental activities.
With this structure, each Group company reports on its environmental
activities as part of its management review, and information is reciprocally shared
with the headquarters. In addition, shortcomings and examples of improvements
are shared throughout the Group to enhance the process for corrections and
improvement. In terms of efficiency, unified certification has also led to significant
cost reductions.
We will continue to work going forward to obtain unified certification at all of
the 39 Group companies.

CO2 Emissions at the Yamaha Motor Group
As a manufacturer of motorcycles and other transportation machinery, the Yamaha
Motor Group considers the reduction of greenhouse gas emissions to be the most
critical environmental issue facing the world today.
We are targeting an annual 1% reduction in CO2 emissions per unit of sales
as a common goal for the entire Group, and are working to reduce emissions in all
of our business activities including product development and manufacturing.
We began working to reduce global utility costs in 2013, with the aim of
establishing both economic and environmental considerations (CO2 reductions). We
are also increasing the efficiency of the overall Group by providing the energy-
saving technologies developed in Japan to Group companies in Japan and overseas.
In 2014, we reduced CO2 emissions per unit of sales by 17% compared with 2013,
resulting in cost reductions of roughly ¥2.3 billion. The Group’s CO2 emissions were
reduced by 35 thousand tons, to 584 thousand tons. Going forward, we will step up
efforts to reduce energy consumption at domestic and overseas Group companies,
aiming to raise our environmental and economic performance on a global scale.
Energy Input at the Yamaha Motor Group
The total amount of energy input at the Yamaha Motor Group in 2014 was 11.05
million GJ, with electricity accounting for approximately 71% (7.90 million GJ). Of
this amount, approximately 80% was used in Asia including Japan. We are
systematically implementing various measures to reduce the amount of energy
used, including the introduction of equipment that makes it possible to analyze and
reduce electricity consumption, and the installation of energy-saving equipment at
factories and LED lighting in offices.
Measuring and Reducing Water Resources
The Yamaha Motor Group endeavors to measure the amount of water resources it uses.
The Group reduced its use of water resources in 2014 by 0.58 million m3 compared
with 2013, to 6.18 million m3, the main components of which were 2.43 million m3
(39%) of underground water and 2.35 million m3 (38%) of industrial water.
We strive to use limited water resources effectively, including through
recycling. We will continue to strive to measure our global use of water resources,
and reduce our water resource consumption through programs including the reuse
of coolant water and water collection (rainwater and other sources) at factories.

Yamaha Motor has developed next-generation electrical power assist drive units for bicycles based on the GREEN CORE concept for smart
power drive units. These units deliver an enjoyable ride with superior environmental performance due to their compactness, light weight, and
high-performance capability—and are being successively rolled out in 2015. These new models achieve a compact, ultra-light weight for a
chain resultant force-type unit, with a significant reduction in the amount of rare earth metals used, for high performance in a compact drive
unit that achieves the same maximum power as existing units. The weight of the bicycle is further reduced with the use of a lightweight
aluminum frame, which, combined with the drive unit’s low center of gravity, makes it easy to drive. These stylishly designed drive units will be
successively installed in major 2015 PAS models, beginning with the Natura series,
and will also be supplied to electrically power assisted bicycle manufacturers in Japan.
We will also continue to develop new drive units based on the GREEN CORE concept
going forward.
Main features of GREEN CORE-based next-generation drive units
1. Compact and lightweight: Reductions of roughly 16% in size and 20% in weight
2. Low center of gravity: New structural design with center of gravity lowered by 12mm
3. High-performance and power: The same 100Nm maximum torque as existing drive units
4. Environmental considerations: Reductions of 35% in the amount of rare earth metals, 28%
in the amount of aluminum, and 40% in the amount of copper wire used
