Initiatives for the Global Environment

Many environmental and resource-related issues which influence the realization of a sustainable society, such as advancing global warming, excessive energy and water consumption, and the loss of biodiversity, are becoming increasingly more serious on a global scale. Against this backdrop, the Paris Agreement, which sets a goal of “holding the increase in the global average temperature to well below 2°C above pre-industrial levels” was adopted at the twenty-first session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 21) held in 2015.

Against this social backdrop, the Yamaha Motor Group considers it important, as a manufacturer, to address environmental considerations through initiatives to prevent global warming, conserve energy, prevent pollution, reduce waste and conserve resources, and also through its core business of personal mobility. This includes the development of compact vehicles with little environmental impact through technological innovation, the spread of Smart Power* products such as electrically power assisted bicycles and electric motorcycles, the research and development of next-generation power sources, and the implementation of programs that contribute to society by using the human resources, assets, and know-how accumulated through our business.

In addition, initiatives to lessen global warming, reduce energy consumption, use resources effectively, improve efficiency, preserve biodiversity, and reduce our environmental impact are carried out across the entire supply chain, with our position regarding the global environment made known to the entire Group as well as to business partners including suppliers and distributors.

*Smart Power: New power sources, primarily for electric vehicles, designed to create a new paradigm of mobility

Achieved Improvement in Power-Generation Efficiency by Developing Smart Motor Generator (SMG) with Integrated Power Generator

1) Smart Motor Generator function equipped with HYBRID System*1 to assist driving force when starting
2) New BLUE CORE*2 engine provides smooth acceleration with low vibration to deliver a comfortable ride.

HYBRID System: The starter generator functions as a motor in response to throttle operation for a maximum of three seconds on takeoff from a stationary position, helping to assist the torque of the engine.
BLUE CORE: Yamaha Motor’s engine design concept which takes riding enjoyment, fuel efficiency and environmental performance to all-new levels. The aim is to achieve greater performance by focusing on the three points of high-efficiency combustion, high cooling performance and loss reduction.

NOZZA GRANDE (Model equipped with SMG; Sold in Thailand and Vietnam)


Direct fuel injection used for first time
in 4-stroke outboard motor

Development of Lightweight, Compact Power Units

A sleeveless cylinder made through plasma fusion technology was introduced to achieve a lighter weight, more compact engine.

Also, to increase fuel combustion efficiency and achieve outstanding torque and power with lower displacement, direct fuel injection, which directly sprays fuel at high pressure and precision into each combustion chamber, was adapted.




Business Activities and Environmental Impact

Yamaha Motor strives to ascertain the environmental impact of its business activities and promotes activities that minimize the effects of its products and services on the environment throughout the life cycle.

In fiscal 2018, CO2 emissions throughout the life cycle totaled 530 thousand t-CO2 (1.8%) in Scopes 1 and 2 combined, and 30,080 thousand t-CO2 in Scope 3, which accounts for 98.2% of the total.

The domain with the highest emissions was Scope 3, Category 11 (Use of sold products), accounting for 84.8% of the total. We recognize that it is vital to reduce CO2 emissions from our customers’ use of our products.


(*) Scope 3: Other indirect emissions are calculated using the Emission Unit Value Database (ver. 2.6) as per the Ministry of the Environment’s Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (ver. 2.3; December, 2017).

Category 8. Lease assets (upstream)
Operating times for copiers and personal computers under lease contracts are included in electricity charges under Scope 2. The emission volume for this category is 0.

Category 9. Shipping and transport (downstream)
Motorcycles account for roughly 80% of the number of items shipped by all operating divisions, and almost all product deliveries to customers in all countries and territories are made at dealerships. The emission volume for this category is 0.

Category 11. Use of products sold
Energy usage per vehicle based on average fuel consumption or rate of electricity use, multiplied by product lifetime in years and annual number of units sold.

Category 13. Lease assets (downstream)
This applies to leased motorbikes, electrically power-assisted bicycles, boats, etc. Because Yamaha Motor provides the same products for leasing, this is included in Category 11, “Use of products sold.” The emission volume for this category is 0.

Category 14. Franchising
As Yamaha Motor does not have a franchising system, the emission volume for this category is 0.

Category 15. Investment
As Yamaha Motor is not considered an investor for the purpose of gaining profit, this is excluded from the calculation.
